Title: Improvements in or relating to mudguards or side-splash guards for vehicle wheels
IPC: B62D25/18
Filed: 1921-01-17
Abstract: 169,657. Sherrington, W. J. Jan. 17, 1921. Lateral-splash guards for road-vehicle wheels, rotatablv mounted at or near the wheel centre as described, for example, in Specification 141,487, have a yielding clutch or coupling interposed between the guard and the spring tending to hold the guard in its middle position. As shown, the carrier sleeve 1, rotatably mounted on a ball bearing (not shown), is fitted with a plate 3 which is pivotally connected at 4 to the red 5 of the spring control-device 5, 7 and is provided with a projection 9 adapted normally to engage with a recess 10 in the rod 5, the parts 11 of the rod being inclined in order to guide the projection into the recess. By these means, the leverage of the spring is automatically reduced when the spring tension reaches a predetermined amount. The lower end of the rod 5 may be forked so as to grip the plate 3 between front and rear limbs, and the effective length of the rod may be altered by connecting the spring thereto at different points 12 along the rod. The plate 3 may be in one with the sleeve.

Title: Improvements in or relating to radio signalling
IPC: H04B14/00
Filed: 1934-01-24
Abstract: 426,227. Wireless signalling. ARMSTRONG, E. H., 211, Central Park West, New York, U.S.A. Jan. 24, 1934, No. 2435. Convention date, Jan. 24, 1933. [Class 40 (v)] Frequency or phase modulation is effected by aperiodic circuits, the phase shift of the carrier wave being directly proportional to the amplitude and inversely proportional to the frequency of the signal. The output from a constantfrequency oscillator 1, Fig. 1, is connected (a) through an amplifier 2 to a resistance 3, and (b) in parallel to two amplifiers 4, 5 coupled at 6 to the signal source 26, and at 9, 10 to an amplifier 12 which feeds back to the resistance 3 currents displaced in phase by the signal components. As shown in Fig. 3, A represents the signal voltage and B the corresponding plate voltages impressed on the valves 4, 5. The vector MN at C represents the voltage across the resistance 3 in the output of amplifier 2 when no signal component is present, whilst ON and NP represent the phase-shift over one cycle of signal current. The resulting phasemodulated carrier is fed through further amplifiers, filters, and current-limiters to the transmitting aerial. Since the time taken to shift the phase is inversely proportional to the frequency of modulation, a correction circuit 27, 28 is introduced at the signal input. This feeds to the transformer 6 a voltage which is inversely proportional to the signal frequency, thereby maintaining constant modulation for high notes and low. The initial small phaseshift may be increased, say for television, to any desired extent by frequency-multiplying, combined if necessary with heterodyning. Specifications 290,642, [Class 40 (v)], and 426,228 are referred to.

Title: A Protector Fitting for Use in Packing Tinned Goods into Cases.
Inventor: PELLING ERNEST
IPC: B65D25/02
Filed: 1918-02-12
Abstract: 122,717. Pelling, E., and Snow, J. Feb. 12, 1918. Packing tins.-To prevent tins that are packed in cases from damaging each other when the cases are handled roughly, protectors such as shown in Fig. 1 are placed between the tins. The protectors are formed with an angular part 1, which fits on a vertical edge of a tin and with a flange 2, which overlaps an adjacent tin; or, for use with curved tins, the part 1 is of curved form. The protectors may be formed at the edge 4 and the part 4a with two or three thicknesses of metal. The protectors are particularly applicable to packing tins of truncated pyramidal form, which are arranged in the case 6, Fig. 3, in alternately inverted order with the corners of the large ends 8 in contact. The protectors are placed on the corners at the large ends of the tins and overlap the adjacent large ends of diagonally adjacent tins. If the tins become relatively displaced, the protectors receive the impact and prevent damage.

Title: Apparatus for filling bottles, jars, boxes or other containers with granular material
IPC: B65B1/36
Filed: 1942-03-02
Abstract: 555,833. Packeting granular material; delivering measured quantities. GILBY, J. A., and MILKFILLERS, Ltd. March 2, 1942, No. 2716. [Class 94 (i)] [Also in Group XVIII] Apparatus for filling bottles, boxes or other containers with a granular material comprises a number of cylinders in each of Which a pair of spaced pistons is reciprocated as a unit, means for adjusting the capacity of the space between the pistons, and means for registering the space alternately with a filling aperture and an outlet aperture as the pistons reciprocate. The machine may be used for filling cartridges or shells with explosive. The cylinders may be stationary or they may be carried by a rotating frame. A machine of the rotary type comprises a number of cylinders C, Fig. 1, carried by a table 2 which rotates about a vertical column 1, the exterior of each cylinder being connected by a shoot 10 with a hopper 9. Within each cylinder is a pair of pistons 6, 7, Fig. 3, which are separated from one another and are reciprocated in unison, so that the space 11 between them forms a measuring chamber that moves back and forth between the shoot 10, from which it is filled, and an outlet 12 through which the contents are discharged into a container D through a vertically-movable nozzle 34. The pistons 6, 7 are connected to pivoted levers 13, 14, Fig. 2, respectively, which are connected by a link 15. This link is pivotally connected with one end of a pivoted lever 20, Fig. 1, which is rocked by a stationary cam 23 so that the pistons are reciprocated as the table 2 rotates. The inner end of the lever 13 is pivoted on the table 2, while the inner end of the lever 14 is pivoted on a disc 25 which rotates with the table 2 but is rotatable relatively to the table by means of an adjusting shaft 29a or by a manually-controlled lever. Thus by adjusting the position of the disc 25 about the axis of the table 2, the lever 14 can be turned relatively to the lever 13 and the capacity of the space 11 between the pistons 6, 7 can be adjusted. The discharging nozzles 34 are movable vertically and are pressed upwards when a container D is placed in position to be filled. When this occurs, a lever 36 draws a plunger 37 downwards against the action of a spring. If a container be absent from the filling position, the plunger 37 is not drawn downwards and prevents the link 15 from moving the piston into the charging position. In a non-rotary machine, shown in Figs. 7 and 8, a number of cylinders are formed in a plate 50 disposed beneath the outlet slot of a hopper 72. Pistons 51, 52 reciprocate in the cylinder and carry charges of material from an inlet aperture 53 on each cylinder to an outlet nozzle 55.

Filed: 1933-01-28
Abstract: 414,113. Starting prime movers. ECLIPSE MACHINE CO., Elmira, New York, U.S.A. Jan. 28, 1933, No. 2753. Convention date, Jan. 29, 1932. [Class 38 (iv).] For starting internal-combustion engines, a common driver-operated control is provided for the carburetter choke valve, the starting motor and the ignition system. As shown, the common control comprises a rod 12 carrying an operating button and connected through a lost-motion connection 16 and a link 17 to the choke valve, which is closed or partly closed by movement of the rod 12 after the lost motion has been taken up. A switch arm 18 operated by collars 19, 21 on the rod 12 moves over a contact member 26 connected by a lead 28 to the ignition circuit and through a switch 31 and lead 32 to a solenoid 7 for closing a switch 4 in the circuit of the starting motor. When the engine is running, the circuit of the solenoid 7 is broken by engine suction acting on a piston 38 carrying a contact member 35 for engagement with contacts 33, 34. The solenoid circuit is also broken by the separation of contacts 45, 46 on actuation of the accelerator pedal 53. In a modification, the manual switch 31 is omitted and the starter control circuit is connected to a contact member adjacent to and shorter than the member 26, so that the ignition is switched on before the closing of the solenoid circuit.

Title: Arrangement for reinforcing weak continuous currents
IPC: H02M3/18
Filed: 1921-01-21
Abstract: 159,499. Reichinstein, D. Feb. 25, 1920, [Convention date]. Telephonic, telegraphic, and other non-contactmaking relays and repeaters.-An arrangement for reinforcing weak direct currents consists of an electrolytic cell connected alternately by a commutator to a source of current maintaining the polarization and to the circuit of the current to be reinforced which reduces the polarization, so that, on the next reversal of the commutator, an increased current flows from the source. Received electric waves rectified by a detector Dt produce a continuous current through a resistance W. The electrolytic cell Z is polarized by a battery A1, and a rotating commutator switch connects the terminal c of the cell alternately to the terminal a of the battery A, and a terminal b of the circuit containing the resistance W. A battery A2 is arranged just to compensate the back E.M.F. of polarization in the cell Z so that, when no received current flows in resistance W, the current is received in the telephone T, but when such current flows, the cell Z is partly depolarized, and when the commutator again connects a and c an increased current flows from battery A1 and its impulses are detected in telephone T. A source of weak alternating current may be substituted for the battery A2 and the commutator K made to run synchronously therewith.

Title: Improvements in or relating to implements for working material lying on the ground
IPC: A01D78/00
Filed: 1961-01-24
Abstract: 975,899. Haymaking machines. C. VAN DER LELY N.V. Jan. 24, 1961 [Feb. 4, 1960], No. 2798/61. Heading A1F. In a haymaking machine of the type having tine-bars each carrying a row of resilient tines, each tine is connected to its tine-bar through two substantially horizontal straight portions which are resiliently deformable about their own axes to enable the tine to be deflected. In Figs. 4, 5 and 7 the tine-bar 47 is of inverted L- shape, the tines 45, 46 being formed in pairs and bolted to the tine-bar at their centre-point. Between the bolt 63 and the tine-stem 45, 46, each tine has a horizontal portion 56, 61 leading into a vertically-disposed loop 55-52, 60-57 which passes vertically through a hole 50, 51 in the tine-bar and merges into the tine-stem 45, 46. In Fig. 15, each double-tine is clamped to the tine-bar 108 at its centre and then has limbs such as 115, 114, 113, which finally bend over the edge of the tine-bar to form the pendant tines (not shown). In Figs. 25, 27 each tine depends from a fixing nut 163 in the tine-bar 149 and has three intermediate horizontal portions 152, 153, 154 between the portion 155 and the tine-stem 148. In each case, the horizontal portions (i.e. 55, 56, 113, 115, 152, 153, 154) are capable of deforming torsionally when the tine encounters the crop, the holes, such as 50, 51, being of sufficient clearance to permit tine movement. As shown in Fig. 4, the upwardly extending loops are capable of acting as scrapers for the adjacent tines during rotation of the tine-bars. The tines are shown applied to a machine (Fig. 1, not shown) having a main frame in the form of a deformable parallelogram and being arranged for direct coupling to tractor hitch-links; the tine-reel is powerdriven from the tractor power take-off. Specification 975,900 is referred to.

Abstract: 1,035,554. Circuit assemblies. UNITED AIRCRAFT CORPORATION. Jan. 23, 1964 [June 26, 1963], No. 3035/64. Heading H1R. A modular circuit assembly, Fig. 7, comprises a plurality of insulating wafers 50, 64, each having terminal areas deposited around at least one edge thereof and bearing thin film and/or solid state circuitry which is connected to the terminal areas, substantially parallel conductors 72 interconnecting terminal areas on different wafers. The wafers are stacked in corner stabilizers 70 upon a header comprising a metal outer member 94 sealed to a glass inner member 96. Plug-in pins 92 extend through glass member 96, the upper ends of the pins being welded or brazed in metallized holes and edge-notches in a transfer wafer 80 having conductive paths which connect conductors 72 with pins 92. The assembly is hermetically sealed in a nickel, copper, or steel can 100 which may be evacuated or filled with helium, dry nitrogen, or a mixture thereof. Wafer preparation.-Wafers of glass or, preferably, ceramic are cleaned, rinsed, and provided with terminals by the vacuum deposition of successive layers of chromium and gold on edge and marginal surfaces of the wafer. These terminals are masked and joined by a deposit of aluminium, which is given an oxide plating- resist coating, after which the terminals are electroplated with nickel or copper; the aluminium is then removed. Thin film components such as resistors and capacitors may be deposited on the wafers, for example chromium, " Nichrome " (Registered Trade Mark) or other resistive material may be deposited on a wafer by vacuum deposition, sputtering &c. and given a protective overlay of silicon monoxide, and resistive paths between selected terminals may be formed by electron beam scribing. Capacitors may be formed from alternate layers of metal and dielectric; or a wafer of barium titanate may have metallic electrodes deposited on opposite faces thereof. Additionally or alternatively, unencapsulated solid-state devices may be alloyed to gold-on-chromium bonding areas on a wafer, such devices being connected to edge terminals on the wafer by gold leads attached by electron-beam welding or by thermo-compression. The conductors 72 which may be of copper, are bonded to the edge terminals on the wafers by electron-beam welding.

Title: Improvements in and relating to electrical cut-outs
IPC: H01H87/00
Filed: 1925-02-03
Abstract: 256,282. Bell, B., and Illingworth, W. H. Feb. 3, 1925. Mercury cut-outs. -In mercury-thread resettable cut-outs of the type described i n Specifications 159,917, 172,446 and 189,284, the reserve of mercury is contained in a compressible rubber reservoir 4 secured between the orificed core e of ceramic material and the lower end of the insulating casing c so that the mercury is in contact with the lower terminal cap a. The core fits tightly within the lower portion of the partitioned inner casing f of metal, a hole in the partition registering with the channel in the coil and communicating with an axial orifice in a metal valve-member 3 fixed to the upper terminal cap b. The upper chamber of the casing j contains mercury which connects with the upper cap through the metal valve but, according to the invention, in order to provide an additional path independent of the valve member, a contactmember with spring tongues 6 is secured to the upper cap by the shank of the valve-member and rubs upon the inner surface of the casing f. The mercury thread is renewed by depressing the knob d, whereupon the inner ends of the guide bolts d' depress the easing f and with it the core e, against the action of the spring 2 on the pin 1, so as to compress the rubber container and force mercury therefrom up the channel to complete the column. On releasing the knob, the inner end of the valve-member bears down again upon the partition. The valve is provided with a venting passage 3g communicating with a channel in the valve-member vented at 3h to the atmosphere. The valve-member prevents the gravitational return of the mercury after expulsion on overload and is formed with inclined passages 3d leading to an axial channel 3<c> and constituting with it a number of acute-angled edges or covers over which the mercury spills, and at the same time presenting on the upper surface a number of deflecting baffles to control the ejected mercury. The valve proper, with a tapered portion to constitute the weir, mav be a separate element screwing into the valve stem. In the case of small current cut-outs where a capillary duct is used and the mercury does not tend to run back under gravity, the valve formation is unneccessary and the inner extremity of the member 3 which does not bed upon the partition is formed to serve simply as a, deflecting baffle. In this form the spring tongues 6 form the sole electrical connection between the upper end of the mercury column and the upper terminal.
