Abstract: 750,881. Archery bows. MEYER, L. S., and SHIRA, G. A., [trading as PARALLEL PLASTICS CO.]. Aug. 23, 1954. No. 24447/54. Class 132(3) The limbs of an archery bow each consist of two thermosetting polyester resins one rigid and one flexible disposed respectively at the face and back, the whole being reinforced by glass fibres extending substantially longitudinally of the bow and moulded as a single unit. The bow is made in the shape shown in Fig. 10, taking up the shape shown in Fig. 6 when the string is fitted, and comprises a handle 20 and limb 21, 21a. At the outer ends of limbs 21, 21a, hooks 22 are formed having string grooves 23 (Fig. 9) merging with a Y- shaped channel where the string loop fits over projection 24. Handle section 20 is heavy and rigid with holes 25 to reduce the weight and is shaped to form a hand grip, which may be wound with tape or the like 26 Shoulders 27 forming arrow supports are provided so that the bow can be used by right-handed or left-handed archers. The bow has straight sides above the shoulders. When the string has been attached to the bow, the face of the bow will be under compression while the back is under tension and different resins are used for the two sides of the limbs to resist these forces. The back of part a (Fig. 10) of each limb is made of flexible polyester resin of substantially the same extensibility as the glass fibres, e.g. a blend of alkyds and monomeric styrene. The face of part a (Fig. 10) of each limb is also a blend of alkyds and monomeric styrene whose strength may be increased. by the use of an inert mineral filler, e.g.. calcium carbonate.

Title: Improvements in or relating to devices for regulating liquid level
IPC: G05D9/02
Filed: 1936-09-08
Abstract: 467,389. Automatic control systems. IGRANIC ELECTRIC CO., Ltd. Sept. 8, 1936, No. 24481. Convention date, Sept. 12, 1935. [Class 38 (iv)] Fluid level and pressure.-Liquid level in a closed container is regulated by a diaphragm subject to the pressure of the liquid and transmission means whereby movements of the diaphragm are conveyed to a control element through the medium of on enclosed body of liquid. In the system described, an electric motor drives a pump 13 transferring condensate from the container 10 to a boiler 12 in a steam heating plant and a degree of vacuum is produced above the liquid level 10a by a second pump 52. The motor 15 is started at maximum liquid level and stopped at minimum level by a switch 17 when a switch 57 is set as shown. It is started either by high liquid level or low vacuum when the switch 57 is in its upper position, a switch 53 in parallel with switch 17 being subject to the vacuum; the motor runs until minimum liquid level and maximum vacuum are obtained. In the lower position of switch 57 the pumps will run continuously. Fig. 1 shows a flexible diaphragm 23 of corrugated phosphor bronze, for example, to opposite sides of which are secured metal discs and bellows 20, 38. Two housings 25, 26 clamped about the diaphragm form fluid-tight chambers connected to the container respectively above and below the liquid level 10a. The bellows 38 is open to atmosphere and is not essential. The bellows 20 and the bellows 19 and connecting tube are filled with fluid. A modification is described Fig. 2 (not shown) employing a rubber diaphragm and detachable bellows. The bellows 19 actuates a snap action switch of the kind described in Specification 434,064, [Group XXXVII], against a spring 18 which is adjustable to determine maximum fluid level; minimum fluid level is determined by adjusting a screw abutment for an element of the switch mechanism. A bellows 55 contains a spring and its interior is subject to the vacuum above the fluid level which may be adjusted by varying the compression of a spring 18a; it actuates a switch of the kind referred to.

Title: Improvements in electro-capillary devices
IPC: H04R23/00
Filed: 1928-08-25
Abstract: 296,102. Latour, M. Aug. 25, 1928. [A Specification was laid open to inspection under Sect. 91 of the Acts, Aug. 26, 1928]. Electrocapillary instruments.-Relates to telephone transmitters or receivers of detectors of electric oscillations which rely upon electrocapillary action. As shown in Fig. 1, an electrocapillary microphone comprises a tube 1, the inner section of which increases towards the upper opening according to the exponential law, filled with an electrolyte 3 such as salt water, acidulated water &c. and dipping into mercurry 2. The electrolyte is covered by a. layer of oil 4 to prevent evaporation. The deformations of the upper surface of the electrolyte which result from the action of the sound waves produce corresponding deformations in the contacting surface of the meniscus 7 and consequently corresponding variations of the potential difference between the conductors 5, 6. In the modification shown in Fig. 2, the meniscus is situated inside a calibrated glass tube 8 connected to a metallic tube 9 which is insulated on the outside. The tube 9 may have frictional sliding contact in a stopper 14 to facilitate adjustment of the meniscus. In order to improve the transmission of the sound waves to the electrolyte a diaphragm arranged in contact with the electrolyte may be provided. The positions of the mercury and the electrolyte may be interchanged and a plurality of units may be connected in series or parallel. The operation of the apparatus is reversible and may be used for transforming varying electric currents into sound waves. Furthermore modulated high-frequency waves mav be transformed directly into sound waves. The apparatus is adaptable to submarine telegraphy or telephony, sea water being used as the electrolyte.

Title: Window regulating mechanism
IPC: E05F11/44
Filed: 1962-06-26
Abstract: 1,015,987. Vehicle window regulators. I.N.M. INDUSTRIES CORPORATION. Heading E2M. In a window regulating mechanism, particularly for cars, a fixed support 27 carries two levers 23, 24 pivoted at fixed points 28, 29 and attached at their ends to a carrier member 22 that supports the window A, a spring 35a being arranged to counterbalance the weight of the window. A connecting arm 34 pivotally connected at one end to the lever 23 has at its other end a handle 36 constrained to move in an arcuate slot 36a during operation of the mechanism. An actuating member 32 pivoted about a shaft at 33 has arranged at its top end a releasable pawl mechanism that engages with a serrated track 33a for locking the window in any adjusted position. Initial movement of the handle 36 in either direction releases the pawl so that further movement of the handle 36 adjusts the window position. In a modification (Figs. 12-16, not shown) the handle 36 and the arcuate slot 36a are replaced by a conventional crank handle connected to a shaft at 33, to which shaft is attached the actuating member which is in turn connected to the connecting arm. The actuating member is attached to the shaft by way of a "lost motion" device containing either bell crank levers or a sliding member acting on a toothed segment so that the window is locked at any adjusted position and is released during the initial movement of the handle. In saloon cars where the vertical movement of the window is constrained between guides in the door, the bottom lever 24 can be omitted and lever 23 bent upwards at the end connected to the window to pivot and slide in a slotted member attached to the bottom of the window. An embodiment is also shown for a rear quadrant window which pivots about one corner. The window may be operated manually or by an electric motor.

Title: Programme sequence control
IPC: G05B19/05
Filed: 1972-05-24
Abstract: 1364800 Microprogrammed systems BUNKER RAMO CORP 24 May 1972 [8 Sept 1971] 24516/72 Heading G4A In a processing system of the type in which instruction words from a relatively slow access (e.g. core) program store S (Fig. 1) addressed under the control of a device 41 are read out to a microprogram counter register UA to address a relatively fast access (e.g. semi-conductor read only) program store U, an additional buffer register N is inserted between the memory S and register UA to hold the instruction word for the succeeding micro-program operation. This increases the speed of operation of the system since it prevents the fast store U standing idle whilst waiting instructions from the slow store S. If, after a cycle of store U a change is required in the next instruction to be fetched from store S a circuit 62 applies an overriding signal to register UA to clear it to zero so that an instruction from store U is read into micro-order register U1 to step the device 41 through a no operation cycle whilst the new word is loaded into the buffer register N. If a new instruction is not available from memory S, e.g. when program counter register P is being loaded, a memory synchronizing circuit 66 disables a clock line 54 to prevent operation of all the registers and memories. Processing time is also conserved if a particular micro-instruction is to be executed repeatedly. This is effected by storing in the store S a repeat instruction having a variable data field for the number r of desired repetitions (up to a maximum of n). In the store U there are provided n separate repeat micro-instruction addresses R 1 -R n . If an instruction at an address Al of memory S is to be repeated, the next address A2 designates the number r of repeats. This address is entered into register UA so that micro-program store U is addressed at R n-r . The micro-order at this address is decoded by a repeated decoder 88 to prevent reloading of micro-order register U1 from the memory U. The output of memory U is however used to increment register UA so that the memory U is next addressed as R n-r+1 . The twelfth bit of the last micro-order of each micro-order sequence (including repeat sequences) is marked to energize a gate OR2 so that the program counter register is incremented to read the next address into store S. Space in a store U is conserved by by-passing the store when a micro-order instruction word stored in memory S represents the complete micro-order (rather than the address at which memory U is to be accessed) since the resulting word from register UA is decoded by circuit 76 as a single micro-order and entered direct via enabled gate AND 2 into register U1 (this being effected by marking the twelfth bit of such words).

Title: Antenna system
IPC: H03H2/00
Filed: 1947-09-08
Abstract: 637,551. Aerials; radio receiving systems. HAZELTINE CORPORATION. Sept. 8, 1947, No. 24676. Convention date, Sept. 17, 1946. [Classes 40 (v) and 40 (vii)] An aerial system radiating with approximately circular polarization includes at least one helical conductor so dimensioned that the average conductor turn has an area equal to the product of the average pitch of the turns times the wavelength of the radiation divided by 2#. The Specification includes a discussion showing how a helical conductor can be regarded as a combination of electric and magnetic dipoles and the relationship stated derived for circular polarization. It is stated that the resonant length of the conductor should be wound into a substantial number of turns. A helical antenna according to the invention may comprise a multi-turn helix 10 which may be fed at its mid-point by a balanced feeder 11. If the coil is shorter than the length required for self resonance, resonance may be achieved by capacitive loading by means of non-radiating radial conductive spokes 14. On the other hand where the length exceeds that required for self resonance capacitive reactance may be inserted in the feeder and between short sections of the helix to balance the excess inductive reactance (Figs. 2c and 2d, not shown). An alternative feed arrangement, which may be used without the extra stubs 25 introduced to preserve symmetry, is shown in Fig. 3b. The length of the transmission line 20 is approximately half a wavelength. An unbalanced (e.g. coaxial) feeder may be connected one side to the helical antenna and the other a set of radially extending conductive spokes arranged below it (Fig. 4, not shown). It is stated that to obtain greater efficiency the dimensions of the helical antenna should be comparable with the radian length (i.e. #/2#) and in some cases this results in a helix of only a fraction of a turn. The construction of a suitable half-turn helix on a cylindrical former is shown in Fig. 5. Four half-turn helical wires are spaced round the former and connected in parallel by radial wires at the ends; the axial length is preferably equal to the radius of the cylinder. Multi-wire helical aerials may be fed at the centre.point of one of the helical wires (Fig. 6, not shown). Radio receiving systems. In a complete communication system using aerials according to the invention, the transmission and receiving aerials should be pitched in the same sense for a direct path. To receive reflected signals but to reject direct ones, however, the receiver aerial should be of reverse pitch to that of the transmitter. A diversity receiving system may comprise two receivers fed by separate helical aerials of opposite pitch sense and having their outputs combined.

An annular channel 16<a> may be provided between the solid nose and the space 27. Cooling of the solid nose is assisted by an annular fin 32 projecting into the cooling space. In cases where the nose tends to burn away at one side only, it is made solid at this side only, the cooling jacket being continued within the nose on the other side. As shown, the tuyere fits within a tuyere cooler 12 and the monkey within a monkey cooler 22 which in turn is fitted within a cinder notch cooler 21.

Abstract: 1311923 Glass fibre-resin composite: finishing fabrics RHONE-PROGIL 10 June 1970 [12 June 1969] 25035/70 Headings D1R and D1S An unsaturated polyester resin 1 glass fibre sheet is produced by exposing the resin or resin-fibre mixture mixed with photoinitiator, to a short period of intense light irradiation to gel its surface, followed by a longer, less intense irradiation of the mixture to cure the resin. The glass fibres may comprise a woven or nonwoven fabric of continuous filaments or cut fibres. The polymer resin comprises maleic anhydride or other unsaturated diacid or anhydride, optionally mixed with saturated analogues such as phthalic, sebacic or adipic acid, or phthalic anhydride, condensed with a diol, specifically ethylene or propylene glycol. The condensate is dissolved in one or more of styrene, vinyl acetate, an acrylate, or other vinyl monomer. The photo initiator may comprise diacetyl, dibenzoyl, benzophenone, benzoin or an alkyl ether thereof. Ortho-hydroxybenzophenone, phenyl salicylate, phenylbenzotriazole or other strong ultra-violet absorber, and azobisisobutyronitrile, benzoyl peroxide or cyclohexanone peroxide or other radical initiator, and hydroquinone as stabliser, may be added.  In one embodiment the glass fibre mat is introduced at 2 onto a regenerated cellulose or polyethylene terephthalate support film 1, followed by the resin at 3. A second support film 4 is placed over the mat, then the sandwich is calendered at 5 to remove air bubbles. Mercury vapour lamps 6 ge1 the resin, then lamps 7 cure it, whilst some diffusion of the vinyl monomer to the surface occurs. The sheet can meanwhile be shaped, e.g. corrugated, by tool 8. The support sheets are collected on reels 9. Alternatively, one or both sheets 4 are coated with resin on one side, and then briefly irradiated from the opposite side, to gel the resin before being applied to the glass fibre mat impregnated with more resin.

Abstract: 1341635 Casting processes LA SOUDURE ELECTRIQUE AUTOGENE PROCEDES ARCOS SA 19 April 1971 [3 April 1970] 25124/71 Heading B3F In a electroslag remelting process, the molten slag 8 is in contact with confining means 4 distinct from the confining means 1 in contact with the pool of molten metal 9. The apparatus may consist of two ingot moulds 1 and 4 separated by a layer of alumina 3 and joined by bolts 6, and the boundary between the slag bath 8 and molten metal 9 is normally maintained slightly below the layer 3. When it is necessary to replace the top mould 4 during a casting operation, the speed of withdrawal of the ingot 10 is increased until the top of the slag bath is below the alumina layer 3. In an embodiment, Fig. 6, the mould is formed by pairs of co-operating shells 31 which are formed in two identical endless chain systems supported by sprockets 32 and 33. The external faces of these shells are cooled in the region where the melting operation takes place by sprays of water. In another embodiment, Fig. 5 (not shown), three mould units (26), (27) and (28), each formed by two mould halves, are provided in a three storey structure. When the pool of molten metal reaches the top mould unit (27), the bottom unit (26) is removed and reinstalled above the top unit. Similarly the unit (28), which is now on the bottom, will later be removed and reinstalled on top of the unit (26). The metal to be melted may be introduced to the slag pool 8 in the form of ingots, bars, wires or powders.
