IPC: F16B19/10
Filed: 1939-05-15
Abstract: 528,773. Friction clutches. NEWTON. N. B. May 15, 1939, No. 14406. [Class 80 (ii)] [Also in Group XXV] Two-part rivets, for example, for use in connection with clutch plates as described in Specification 443,608, consist of one inner hollow stud b of soft metal such as copper and an outer sleeve c of harder metal such as steel. In the application to clutches the friction lining h' is connected to the backing plate g by pressure between the head a of the stud and the end of the sleeve c. Mounted on the sleeve on the backing-plate c and spring washer k the flange d of the sleeve limits the separation of the backing plates. The tubular shank b of the stud is expanded into a countersink c in the sleeve. In a modification the sleeve has a reduced end forming another shoulder against which the plate 9 is held by winding the sleeve into a countersink therein. In this construction the backing-plates and spring washers remain assembled during the renewal of the linings. The studs are inserted alternately from opposite sides of the plates.

Title: Improvements relating to copying telegraph systems
IPC: H04N1/12
Filed: 1929-05-14
Abstract: 311,711. Kolster-Brandes, Ltd., (Assignees of Broker, W. M.). May 14, 1928, [Convention date]. Copying-telegraphs.-In a copying-telegraph apparatus a plane surface is scanned with light from a. stationary source, the light being focussed on the surface by a lens oscillating in an arcuate path, the light passing through the surface and then being directed on a stationary photo - electric element. At the transmitter, Fig. 1, light from a source 16 travels along a hollow tube 21, rotatable in bearing 22 and carrying hollow extensions 18, 19 perpendicular to the axis. The light is reflected by prism or mirror 24 along the tube 19, is focussed by lens 27 on to the translucent document 13 supported on a glass sheet 38, is then collected by lens 28, reflected by mirror 29 along tube 18, and finally reflected at 31 on to a photo-electric cell 11. A cam 33 driven by a motor 34 drives an arm 36, which oscillates the arms 18, 19 at a definite rate to and fro across the document 13. The document 13 is advanced a small distance perpendicular to the scanning motion either continuously or intermittently at the completion of each swing of the scanning arms. The light from source 16 is modulated at an audible frequency, say 1000 cycles, by a perforated tone wheel 39 driven by motor 41, and interposed at some point between the light-source and the photo-electric cell. An amplifier 43 has its input connected to the cell 11, and its output to a radio-frequency modulator 44 associated with a master oscillator 46, the modulated output being passed through amplifier 47 and impressed on a transmitting aerial 48 At the receiver, Fig. 2, the incoming signals are amplified and impressed on a spark gap apparatus 56, comprising two electrodes 58, Fig. 4, supported by an insulator 57 formed with an annular ridge 59, which rests on the photographic paper 54. The unit 56 is mounted on an arm 67, oscillated by cam 69 and rod 72 in synchronism with the transmitting mechanism. The paper 54 is also advanced in synchronism with the document 13 at the transmitter. Synchronous movements.-A synchronizing frequency is radiated by the transmitter, once for every complete cycle of the scanning mechanism at the transmitter, as follows. The arm 18 at the end of its swing closes the switch 74, which impresses a modulating frequency differing from the tone frequency of the wheel 39 upon the modulator 44. At the receiving station the cam 69 is driven through an overrunning clutch 78 at a slightly greater speed than the transmitter cam 33, and the synchronizing signal is selected from the amplifier 53 by a filter 76, and actuates a tripping solenoid 77 which allows a member 79, carried by the cam 69, and normally engaged by the solenoid rod, to rotate for another complete turn.

Title: Information input device
IPC: G06F3/023
Filed: 1973-03-29
Abstract: 1415469 Electric selective signalling OMRON TATEISI ELECTRONICS CO 29 March 1973 [4 April 1972] 15220/73 Heading G4H An information input device (e.g. for an electronic desk calculator) comprises a keyboard output unit 1 comprising input lines L1-L7 connected in pairs by switches K1-K21 each closed by the depression of a corresponding key. A generator TG cyclically produces bit and digit timing pulses t1-t5, T1-T14, the width of one pulse T being equal to the sum of the widths of pulses t1-t5. Pulses T7-T13 are inverted and fed to lines L1-L7: a NAND gate G1 thus receives one LOW (Lo) and six HIGH (Hi) signals during each T pulse duration (when no key is depressed) and its output is Hi. Depression of, e.g. K9 short-circuits L2 and L5, whereupon the Lo signal on L2 is replaced by the Hi signal on L5, and vice versa. Thus the Hi output from G1 goes Lo while pulses T8 and T11 are applied. In the embodiment of Fig. 1 the two Lo output from G1 enable gates G3, G6 to set flip-flops F2, F5; the flip-flop output (0100100) representing the depressed key in 2/7 code is then fed to an encoder E and a calculation circuit C. In the Fig. 2 embodiment the inverted T6 pulse sets flip-flops F10, F11. Pulses t2, t3 then pass through gates G9, G11, G13 to an adder FA and a circulating register R during each T pulse duration until the output from G1 goes Lo-i.e. a count of 6 (00110) is accumulated in R for each T pulse which does not produce a Lo output from Gl. The first Lo output resets F10, whereupon pulse t1 (count of 1) passes via gates G10, G11, G13 to FA during each T pulse until the second Lo output resets F11. The total count in R (e.g. 6+1+1 for K9) uniquely represents the depressed key and is output to a calculation circuit C.

Title: Apparatus for measuring the weight of liquid in a tank
IPC: B64D37/00
Filed: 1972-04-04
Abstract: 1373574 Measuring weight of liquid in tank HONEYWELL Inc 4 April 1972 [19 April 1971] 15275/72 Heading G1N The weight of fuel in an aircraft fuel tank is measured by sending pulses down a transmission line 2, measuring the time taken to receive reflections from the fuel surface and the bottom of the line, and computing volume, density and hence weight of the fuel. An initial reference pulse for the timing may be derived from a deliberate mismatch at the top of line 2. To give a linear output even though the tank is not of constant crosssection, the line 2 may have appropriate non constant inductive or capacitative reactances, as by comprising a central helix of non constant pitch surrounded by a tubular conductor, Fig.5 (not shown), or having a profiled dielectric (47), Fig.6 (not shown), or having a profiled ferromagnetic sleeve. Several tanks may be monitored with a single pulse generator, detector and computer, each transmission line sensor receiving pulses from the generator 3 via a respective delay, Fig.3 (not shown).

Title: An improved method and means for intercepting night flying hostile aircraft
IPC: B64D47/04
Filed: 1940-09-16
Abstract: 574,970. Searchlights for use on aircraft. COTTON, F. S., and HELMORE, W. Oct. 16, 1940, No. 15311. [Classes 75 (ii), 75 (iii) and 75 (iv)] Relates to means for illuminating night-flying enemy aircraft by a searchlight carried on a. pilot aircraft and only rendered operative when the target is within effective range of the beam. According to the invention, the pilot aircraft carries a detector, embodying a sound or other wave transmitter and a receiver, which has its datum axis fixed in line with or parallel to the fore and aft axis of the aircraft, the searchlight being normally similarly disposed for automatic direction on the target by steering the aircraft in the direction recorded by the detector. Fig. 1 shows a searchlight 10 fixed in the nose 'of the aircraft and supplied with current from a heavy-duty accumulator 14 through a switch 13. The detector 16 of known kind which records the direction and range of the target enables the lens of the light to be adjusted to vary the divergence of the beam to suit the indications of range given by the detector. Shutters 19 for the light are operated from a remote control 20. Fig. 2 shows a searchlight 21 which can be extended from or retracted within the aircraft by fluid-pressure under the control of a valve 24 applied to a piston 23 attached to a hollow support 26. A training motor 28 and an elevating motor 29 are controlled from a box 30 to suit the indications of a detector 16. The pipe lines and electric cables pass through the hollow piston rod. By adjusting the searchlight, the target can be retained in the beam although the pilot aircraft is steered away from the target.
