Title: Improvements in or relating to aerial systems
Inventor: CLOUGH NEWSOME HENRY
IPC: G01S1/02
Filed: 1957-01-23
Abstract: 818,347. Directive radio systems. MARCONI'S WIRELESS TELEGRAPH CO. Ltd. Oct. 15, 1957 [Jan. 23, 1957], No. 2438/57. Class 40 (7). An aerial system of rotatable directivity for use in direction finding or at a radio beacon comprises a set of similar aerials arranged at equal intervals round a central axis, the aerials being in diametrically opposite pairs which are joined by a diametrical conductor shaped to form a part turn about the axis, and a coupling loop rotatable about the axis and inside, and in coupling relation with, the cage of conductors formed by the crossing part turns. In one convenient construction the cage referred to above is formed by a cylindrical structure having a closed upper end 9 and its curved surface split into as many parts 10 as there are aerials by cuts parallel to the axis. Each of the aerials, which as shown are radial elements arranged in opposing pairs 1a, 1b; 2a, 2b; and so on, is connected to one of the sections 10, at its lower end. The coupling loop 11 fits into the cylinder and rotates within and about the axis thereof. The overall length of a pair of elements such as 1a and 1b and the connection between them is made half of the working wavelength and rotation of the loop 11 produces a rotating figure-of-eight diagram. In another arrangement, shown schematically in axial section in Fig. 3, the pairs of aerials consist of the vertical sides 12, 13 of a frame and are joined at their upper ends by conductor 14 and at their lower ends by conductor 15 containing the part turn 9, 10 which couples with the rotatable loop as before. Both the above embodiments are subject to zenithal error and may be enclosed in a polarizing screen, slotted waveguide or tower. In a further embodiment shown in axial section in Fig. 4, each aerial is a centre fed dipole and the upper and lower sections of opposite pairs of aerials are each connected by diametrical conductors 15 including part loops 9, 10. These extend in opposite directions and completely surround the coupling loop 11. The upper and lower sets of part loops may each comprise a split cylinder as above described and screening as indicated at 18 may be introduced.

Title: Improvements in or relating to the automatic fastening of vehicle doors
IPC: E05B65/42
Filed: 1924-01-31
Abstract: 223,464. Stedman, L. B., and Sterling, A. Jan. 31, 1924. No Patent granted (Sealing fee not paid). Railway-carriage doors and the like, fastening automatically; striking-plates and staples for locks and latches.-The spring-shot latch bolt 7 of a vehicle door fastening mounted on the member A is secured in the closed position by a spring- pressed bolt member a, integrally or otherwise connected with a bell-crank lever c pivoted in a casing on the member B, the lever c being stated to be secured against operation whilst the vehicle is in motion by a pendulum P, since the projection 5 on the horizontal arm of the lever C can only work in the vertical slot 3 in the pendulum bob when the vehicle is at rest and the pendulum P hangs in the vertical position. In a modified construction, the projection may be on the pendulum bob and the slot in the lever C. The bolt 6 may be operated to release the latch 7,. when the vehicle is at rest, by means of a spring- retracted bolt 10 mounted on the member A and operable by a handle 8 connected thereto either by a lever 9 or by a raok-and-pinion engagement, or the bolt 10 may be dispensed with and the bolt 6 operated directly by a follower. Any undue oscillation of P is damped by forming the lower part of the casing on B as a fluid container and connecting the pendulum by a rod 20 with a piston 18 working in a cylinder 19 the wall of which is provided with an orifice 21, or the piston 18 may be dispensed with and the pendulum bob provided with transverse vanes. In cases of emergency the pendulum may be brought back to the vertical position by a key-operated, pivoted, T-shaped member 22 having turned-up edges 24 adapted to co-operate) with the pendulum. In the construction shown in Fig. 7, one or two pendulums P are arranged to control a number of vertical rods 5<a> each connected to a lever c. A weighted or spring-controlled lever 26 is pivoted at 4a on which pivot is also mounted a link 27 pivoted at 25 to a rod 5b the other end of which is pivoted to a second link 27 which may be connected to a second lever 26 and pendulum P. The levers c can only be operated so as to lower the rods 5<a> and depress the bar 5b when the pendulums P are in the vertical position so as to allow the projections 5 on the levers 26 to enter the vertical slots 3 in the pendulum bobs.

Title: Improvements in and relating to Dash-pots.
IPC: F16F9/16
Filed: 1918-02-13
Abstract: 120,682. British Thomson - Houston Co., (General Electric Co.). Feb. 13, 1918. Dash - pots. - A dash-pot, particularly intended for reducing axial vibrations in a turbine or like shaft, comprises a cylinder 14 fitted with a piston 13 to which is connected the end of the shaft 5, valves 18 spring- mounted in the end wall 17 and opening inwardly into the cylinder 14, a casing 22 having a corrugated or fluted wall 23 which forms a flexible diaphragm, and a conduit 24 by which oil or like fluid is supplied under pressure to the casing 22 and cylinder 14. Normally, the wall 23 of the casing is distended so that, when any movement of the piston away from the end wall 17 occurs and the valves 18 open, the wall 23 assists the flow of fluid through the valves but resists the return movement of the piston. The latter movement is effected with the valves 18 closed and the fluid forcing its way past the piston rings 13a to the drain-pipe 26. In a modification, Fig. 2, both end walls 15, 17 of the cylinder are provided with valves, the additional valves 27 leading into an annular chamber 28 connected by a pipe 30 to the casing 22.

Title: Improvements relating to the manufacture of moulded articles from moulding powders
IPC: B29D19/00
Filed: 1948-01-29
Abstract: 634,764. Moulding buttons, slides &c. from different ly-coloured moulding powders. HORNFLOWA, Ltd., and WINTER, H. A. M. Jan. 29, 1948, No. 2720. Addition to 566,837 and 588,635. [Class 87 (ii)] In Specification 588,635 a process is described in which a mould comprising parts A<SP>1</SP> A<SP>2</SP>, B, C, Fig. 1, is filled with heaps of differently-coloured moulding powders G, F<SP>1</SP> F<SP>2</SP> (by a method described in Specification 566,837), the combined heap is then pressed into a volume small enough to be contained in the middle mould part A<SP>1</SP>, as shown in Fig. 2, the part A<SP>2</SP> is separated from the remaining mould parts and turned upside down, graining recesses formed by the mould part C are filled with powder, and the material is then pressed a second time. The product of that process is a tablet or preform that is to be moulded later under heat and pressure, for finally setting the moulding powder, into a finished button or other article. In the present process, which results in the production of a finished article, the plunger K<SP>1</SP>, Fig. 2, employed for the preliminary compression of the powder to form a tablet in the part A<SP>2</SP>, has a moulding face corresponding substantially in shape to the moulding face of a second plunger K2, Fig. 6, which is used to press the tablet out of the part A<SP>2</SP> and against the mould top B<SP>2</SP> to mould the final product, for which purpose the parts K2, B<SP>2</SP> are formed with flash lands L<SP>1</SP>, L<SP>2</SP> surrounding the shaped mould parts, so as to co-operate in the manner of an open flash mould and extrude superfluous material through the narrowing gap formed between the flash lands as they close. The (hot) mould is kept closed as shown in Fig. 6, until the material has been cured, and may then be placed between a pair of cooled platens in a power press to improve the surface of the moulded article and facilitate its subsequent removal from the mould. The extrusion shown in Fig. 6 results in the basic material forming the peripheral portion of the preform being forced out, leaving coloured material showing at the edge. A semi-positive type mould (Fig. 7, not shown) may be used, the flash in this case being extruded into a gap in the mould parts. To reduce transference of heat from the platen P, Fig. 8, to the tool plate T that carries the plunger K, the plunger stands proud of the plate and the plate does not contact the platen. The plunger is secured to the plate by means of a spring clip S.

Abstract: 1299861 Valves FAIREY HYDRAULICS Ltd 13 Jan 1970 [17 Jan 1969] 2889/69 Heading F2V [Also in Division B1] An hydraulic or pneumatic system comprising a reversible pump (10) and motor (11) connected in a closed circuit (Fig. 1, not shown) has a filter 13 in each line, the filters having by-pass valves automatically opened on reversal of flow so that only the filter downstream of the pump and upstream of the motor filters, the other being bypassed to prevent accumulated solids being backwashed into the circuit. Fig. 2 shows a filter on forward flow, fluid passing inwards through the filter element then out through valve housing 15, through sleeve-like by-pass valve member 27 and past check valve disc 26. On flow reversal (Fig. 3, not shown), the pressure distribution allows valve disc 26 to descend under its spring 35 to close the end of valve sleeve 27, whereupon the pressure forces both valves down against spring 28 to expose by-pass apertures 33. End cap 22 of the filter housing completely encloses the valve housing 15 which screws into it at 21.

IPC: C08K5/132
Filed: 1952-02-04
Abstract: 2:21- Dihydroxy-4:41 - dialkoxybenzophenones are used as light stabilizers for synthetic resin and cellulose ester compositions. The specified resins and cellulose esters are polymerized ethylene, styrene, vinyl chloride, vinyl ethers, vinyl esters, and acrylic acids, cellulose acetate, nitrate, and cellulose acetate butyrate. In an example, a cellulose acetate film contains 2:21 - dihydroxy - 4:41 - dimethoxybenzophenone prepared in a casting solution containing also triphenyl phosphate, ethylene glycol-mono methyl ether, ethyl acetate, and ethanol.ALSO:The invention comprises 2:21-dihydroxy-4:41-dialkoxy benzophenones obtainable by causing a resorcinol dialkyl ether dissolved in a chlorinated ethane derivative to react in presence of anhydrous aluminium chloride at 0 DEG -4 DEG -C., with carbonyl chloride.  Alternatively the products may be obtained by alkylating the tetra-alkali metal salt of 2:21:4:41-tetrahydroxybenzophenone with 2 mols. of alkyl halide or other alkylating agents.  In examples the condensation of resorcinol dimethyl ether, diethyl ether, dipropyl ether and diisoamyl ether with carbonyl chloride as above is described, to give the corresponding 4:41-dialkoxy products, and the alkylation of the tetrasodium salt of 2:21:4:41-tetrahydroxybenzophenone with isoamyl bromide to give the 2:21 dihydroxy-4:41 diisoamyloxybenzophenone, and the 4:41-diethoxy-dihexyloxy and dioctyloxy-, by similar methods; The products are yellow solids with a useful absorption of ultraviolet light in a composition without impairing its stability.  They may be employed in film-forming materials such as cellulose esters.

Title: Improvements in or relating to internal combustion engines for locomotives and other purposes
IPC: F02G3/00
Filed: 1927-02-03
Abstract: 265,599. Hildebrand, R. Feb. 8, 1926, [Convention date]. Locomotives, internal-combustion engine.-For working a four-stroke or two-stroke Diesel or other engine under load without increasing the maximum pressure in the cylinders, an auxiliary power medium under pressure is heated externally of the engine and is introduced into the cylinders during the power stroke after the combustion is completed and preferably after the expansion of the gases of combustion to a pressure equal to that of the auxiliary medium. The invention is applicable to engines in which supercharging takes place, and the auxiliary medium may be steam, compressed air, products of combustion, or a mixture, of these, and may be admitted by the means shown in Fig. 2. A supply pipe 34 and valve 36 are connected to the engine cylinder 18 by a fluid-actuated valve 22, the stem of which carries a piston 25 sliding in a valve cage 23, the valve being normally closed by a spring 24. The space between the valve 22 and the piston 25 is connected by passages 38, 40, 41 to the space above the piston and to a space behind a piston valve 29 actuated by a cam 32 on an engine-driven shaft 33. The valve 29 is normally held by a spring 30 in the position shown, in which the space above the piston 25 is connected by passages 43, 45 to the atmosphere. When the valve 36 is opened, the pressure of the auxiliary medium holds the valve 29 in contact with the cam and the space above the piston 25 is connected continuously to the pressure medium and also intermittently to the atmosphere, opening the valve 22. The operation of the valve 22 may be timed by axial adjustment of the cam 32 on its shaft, the recess 46 in the cam having an inclined end 48. As applied to a locomotive engine 5, Fig. 1, the auxiliary power medium may be steam from a boiler 53 heated by exhaust gases from the engine exhaust pipe 55.

Title: Improvements in or relating to the measurement of velocities
Inventor: HAYES MONSON HENRY
IPC: G01S13/60
Filed: 1958-01-31
Abstract: 887,646. Echo sounding; radar. GENERAL PRECISION Inc. Jan. 31, 1958, No. 3299/58. Class 40(7). In an apparatus for determining the relative velocity of two objects, the first object, for example a ship, carries transmitting and receiving apparatus, a movable receiver and means for moving this receiver such that the difference frequency between the transmitted wave and the wave reflected from the second object, for example the sea bed, is reduced to zero. The radiated energy is of sonic or radio frequency and is pulsed or continuous. In a ship-borne apparatus, Fig. 2, pulses of energy are directed toward the sea bed and, after reflection, detected by the movable receiver 16. The Doppler frequency is obtained in a detector 17 and a signal proportional to this frequency fed to a servo-system 19 comprising an amplifier, motor, and generator. The motor drives the receiver 16 at such a speed that the Doppler frequency is reduced substantially to zero. The output of the generator, which is coupled to the motor, is indicative of the speed of the receiver, this speed being the speed of the ship since the receiver must be stationary relative to the sea bed when the Doppler frequency is zero. To correct for pitch or roll of the ship a circuit comprising a resistor R-3 and a cosine potentiometer R-2 is provided, the wiper of the potentiometer being adjusted in correspondence with the pitch or roll angles. In a second embodiment, Fig. 3 (not shown), a number of receivers are used, all being rotated about a common axis and having connections to a commutator such that only the receiver moving most nearly to the horizontal is put in circuit. The brush to the commutator is kept vertical by means of a gyro- and servo-system.
