L. ; 4905, 39th Avenue, Long Island City, New York, U.S.A.) July 29, 1932, No. 21416. Convention date, Aug. 14, 1931. [Classes 40 (iii) and 40 (v.] A carrier current system transmitting a wide band of frequencies comprises a plurality of channels arranged in groups so disposed in the frequency spectrum that those in one group lie between those in another group. In the system described low frequency lines l1, l2 &c., Fig. 1, are divided into groups A-R each containing for example sixty lines, and each of which passes to a modulator M fed from generators G1-G60 with intermediate frequencies ranging from say 263 KC to 499 KC. and separated by 4 KC. The lower sideband is selected by band filters CBF1-CBF60 the output from the odd filters being taken to a valve amplifier A1 and that from the even filters to an amplifier A2 both amplifiers feeding a line individual to the group such as L1 for group A, L2 for group B and so on. The amplifiers A1, A2 may be replaced by resistance pads 7, 8, Fig. 3, the input circuits 9, 10 and the common output circuit 19 being arranged as shown or by a hybrid coil 21-24, Fig. 4, arranged as shown. The total output from each of the groups A-R is dealt with in a manner similar to that from each line l1, l2, &c., passing to modulators M<1> fed from generators C1-C18 with radio frequencies ranging from say 1080 KC. to 5160 KC., and separated by 240 KC. The outputs from the modulators pass to band filters GBF1-GBF18 the output from the odd filters being taken to an amplifier A3 and that from the even filters to an amplifier A4 both amplifiers feeding a further amplifier A5 connected to the outgoing line LE which is preferably of the coaxial conductor type. The receiver circuits are also described (Fig. 2, not shown) and comprise a similar arrangement of apparatus to the transmitter, the amplifiers operating in the reverse direction and the modulatiors being replaced by demodulators and curves are given (Figs. 5 and 6, not shown) showing the impedance-frequency characteristics of the band filters CBF and GBF.

Title: Improvements in or relating to fuel metering for internal combustion engines
IPC: G01F9/02
Filed: 1951-09-14
Abstract: 722,261. Fuel-consumption indicators; indicating-apparatus. CHARLES, G. R. S. Dec. 15, 1952 [Sept. 14, 1951], No. 21689/51. Classes 106 (3) and 106 (4). The fuel pump of an internal combustion engined vehicle and the odometer or a road wheel of the vehicle are connected respectively to two inputs of a differential gear, at least one of the connections including a variable-speed drive which is adjusted according to the rotation of an output element of the differential gear so as to balance the two inputs, and the angular position of the output element, which corresponds to the fuel consumption with respect to the distance travelled, is indicated. Cones 21, 22 having hard rubber peripheries, are driven respectively by the fuel pump and odometer and are engaged by bronze wheels 35, 36 which drive rubber rollers 34, 37 geared to the crown wheels 24, 25 of a differential gear mounted with the rollers and bronze wheels in a frame 33. The planet-wheel carrier 27 of the differential gear is fast with a shaft 28 which has a threaded portion engaged in a fixed nut 41 and a splined portion which rotates a shaft 42 geared to a pointer 44. If the wheels 35, 36 are driven at different rates, the shaft 28 is rotated and consequently moves with the frame 33 longitudinally, thus altering the drive ratios to the wheels 35, 36 until a position is reached where the wheels 35, 36 are rotating at the same rate. This position corresponds with the ratio of the rates of rotation of the cones 21, 22 and is indicated by the pointer 44 which co-operates with a scale showing the existing miles-pergallon ratio. The wheel 35 may be arranged to slip at either end of the cone 21 to prevent damage when the vehicle is coasting or stationary. The cone 21 may be driven through an electric coupling.

Title: Radar display system
IPC: G01S7/06
Filed: 1976-05-25
Abstract: 1519412 Radar displays BENDIX CORP 25 May 1976 [11 July 1975] 21710/76 Heading H4D The Specification describes a development of the digital radar display device described in Specification 1,398,506 and relates to the utilization of R.A.M.'s as the main memory, read-out data from which, at the "higher than p.r.f." rate for display purposes, and including at least a dual readout from any one range sweep data word stored, being possible without requiring provision of an output buffer means, said readout data being fed direct to a D to A converter and then to display, where each range sweep video signal is displayed twice in succession. The received radar video signal is fed in digital form to two buffers as in the prior specification, and outputed therefrom, in two parallel word trains, each bit thereof corresponding to one of 128 range bins, to a respective memory unit 25a comprising R.A.M.'s 52a, 53a, 54a, 55a, or 25b comprising R.A.M.'s 52b, 53b, 54b, 55b. Each memory unit comprises a store for 128 words one of which is updated once per radar p.r.p. Address multiplexer 66 is arranged to readout all of the stored information within one radar p.r.p., at the basic system information rate f 1 . Each R.A.M. comprises a 64 Î 64 storage matrix addressable as to row and column sequentially (under the control of the Row Access Strobe (RAS) and the Column Access Strobe (CAS) signals respectively) along address lines 90-95, from address multiplexer 66. In operation, for each memory section, the elements of an enabled row pair are sequentially written with the most recently received range sweep word from the respective buffer and integrator 14 or 16, at input 32 or 33 respectively, at a specific one of the read scans of each memory unit, and controlled by an input signal at 36 which controls a WRITE signal from AND gate 62. A range sweep word to be read and displayed is actually written on two rows of a respective R.A.M. unit, and, each pair of rows is read out twice, due to an idling action in counter 64 which controls multiplexer 66 and shift register 68 which enables, by counting a logic zero round AND gates 72, 74, 78 and 80, a respective pair of R.A.M. units 52a, 52b etc in turn. Counter 64 controls multiplexer 66 to address sequentially the elements of each selected row and includes standard counting portion 64a, and flip-flops 64b and 64c. Flip-flop 64b is toggled by an output appearing on output 7 of counter 64a corresponding to the first bit of the second row of a pair of rows but is arranged to produce no output signal and thereby "idles". In this way counter 64 is arranged to "miss a beat" and count each pair of rows containing a range sweep word twice, which words are read under the action of addressing multiplexer 66 and fed to D to A converter 26, Fig. 1, and thence to be displayed adjacently on CRT 28.

Title: Improvements in or relating to hammer type stapling machine
IPC: B25C5/08
Filed: 1952-08-29
Abstract: 737,926. Hammer staplers. SPOTNAILS, Inc. Aug. 29,1952 [Sept. 1, 1951], No. 21759/52. Class 89 (3). In a hammer stapler comprising a handle 35, a magazine 37 for a roll of staple blanks, a driver head 38 and a striker member 98, 99 vertically slidable thereon, the driver blade 90 and staple former 91 are fixed to the head and cooperate with the striker to sever and drive the leading staple and to form the next one. Return movement of the striker member effects the feed of the staple strip. The magazine is provided with a hinged door 60 secured by a resilient stud 70 and socket. The striker member 98, 99 is closed at the upper end by a pivoted latch member 174 which is slotted to engage over ears 180 on the casing member 99, being retained by resiliently mounted pins 183 engaging holes in the ears. The striker member includes an anvil 108 which has a shearing edge 118 to co-operate with the driver 90, and a reduced portion therebehind to co-operate with the former 91. In one form, Fig. 9, the staple strip 31 is fed forward step by step by spring- pressed pawls 145 pivoted on a lever 148 which is itself pivoted at 150 to a spring-pressed plunger 133 slidable in a bore 132 in the head block 78. The plunger carries at its lower end a shoe 141 which serves to hold down and flatten the staple strip. Rocking of the lever 148 to move the feed pawls is effected by a stop 155 pushing down a plunger 153 and by a pin 168 both of which act on a tail 167 of the lever. A stud 93 co-operates with a cam surface 165 on the lever 148 to keep the pawls 145 clear of the driver and former. Retrograde movement of the staple strip during loading is prevented by spring-pressed pawls 170. Tilting of the formed staples is prevented by flat springs 127 engaging behind their legs. In a modification, Fig. 20 (not shown),.the plunger 133 is dispensed with and the pivot pin 150 of the lever 148 is slidable in a vertical slot in the head block. The striker is pressed downwards directly by a pair of coil springs. In another modification, Fig. 23, feed of the staple strip is effected by a pair of toothed wheels 211 carried by a spring-pressed plunger 205. The wheels 211 are operated from a cam 228 on the head block 78<SP>11</SP> through lever 222, links 225, pawl 218 and ratchet 219.

Title: Device for testing magnetic thin layers
IPC: G11C11/14
Filed: 1975-05-21
Abstract: 1510658 Testing magnetic thin layers PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 21 May 1975 [24 May 1974] 21804/75 Heading G1N In order to test magnetic thin films to be used in bubble domain devices for defects parallel domains are produced in the film 4 by a magnetic medium 1 in which a pattern 2 having the same periodicity of elongate areas magnetized alternately in opposite directions is longitudinally recorded and the domain pattern is visually inspected by a magneto-optical device. The bubble layer 4 grown epitaxially on non-magnetic substrate 3 is subjected to the magnetic field from a tape 1 on which is written by a recording head a magnetic pattern 2 having a wavelength which is between 1 and 4 times the stable strip width of the domains. Polarized light from source 7 and polarizer 8 is directed by polarization microscope 6 on to the film 4 and the image produced after reflection from the film 4 and analyzing by analyzer 9 is inspected. The pressure of a defect in the layer 3 results in the parallel lines of the image being disturbed, Fig. 2 (not shown). By slightly moving the film with respect to the tape 1 the defect is better visualized since it retains its own pattern upon moving while the strips are bent out around the defect, Fig. 3 (not shown). The tape to film interaction can be intensified by carrying out the procedure in the presence of weak alternating magnetic field the direction of which is normal to the film. Alternatively a uni-directional magnetic field may be applied to the film either normally or parallel to the film 4. In order to achieve a gradation of the defects the amplitude of the signal written in tape 1 may be varied stepwise or a non-magnetic plate 10 of a transparent material having a reflecting surface and a step-like varying thickness may be interposed between the tape 1 and film 4.

Title: Improvements in overthrow guards for the needles of knitting machines
IPC: D04B15/32
Filed: 1919-09-09
Abstract: 151,255. Wilcomb, J. F. April 12, 1919, [Convention date]. Overthrow guards for needles.-Slidable friction elements such as jacks 26 are provided in the slots of the needle carrier individual to the needles and are adapted to be struck thereby, near the end of the knitting stroke. The jacks 26 are taken up on a low angled cam 27x and by their resistance to the impact of the needles act as guards to restrain the needles from overshooting the lower point of the stitch cam. The tails 26<x> of the jacks are cramped to engage the walls of the needle slot and thus provide frictional resistance tb prevent the overtlirow of the needles. Wear due to impact of needles is spread over a large number of jacks instead of being concentrated on one part of a guard cam, and wear and upsetting effect on jacks and needles is automatically neutralized and compensated. The device may be used in conjunction with the improved knitting or crochet needle unit described in Specification 141,660.

Filed: 1952-09-04
Abstract: 709,358. Valves. SHELL REFINING & MARKETING CO., Ltd. Sept. 4, 1952, No. 22277/52. Addition to 668,451. Class 135 A modification of the balanced valve of the parent Specification has the application of the pressure at the delivery point of a conduit (or a pressure proportional thereto) and of control pressure to the respective diaphragms or plungers 19, 20 reversed so that the diaphragm or plunger facing the valve seat 14 is exposed on one face to the control pressure in a chamber 27. The arrangement enables the valve to be used to open a bye-pass conduit from a main conduit upon cessation of flow in the latter, a chamber 25 being connected to the throat of a Venturi in a conduit connected in parallel with a portion of the main conduit which has a spring-loaded valve to ensure that a proportion of the flow takes place through the Venturi. Thus, the rise in pressure in the chamber 25 consequent upon cessation of flow through the Venturi causes the valve to open. A pipe 34 with a valve 32 enables any liquid which leaks past the piston 19 to be drained. As in the parent Specification the control pressure may be that of a spring. The seat 14 may, alternatively, lie in a plane normal to the direction of fluid flow.
