Patent GB-647844-A (GB)
Title: Ultra-short wave amplifier
IPC: H03G11/00
Filed: 1948-02-17
Abstract: 647,844. Pulse modulation; receiving circuits. PATELHOLD PATENTVERWERTUNGS & ELEKTRO-HOLDING AKT.-GES. Feb. 17, 1948, No. 4598. Convention date, Feb. 17, 1947. [Class 40 (v)] Low noise reception of time (phase or duration) modulated pulses is effected by passing carrier pulses from a high-frequency stage of a receiver over a rectifier 25 having associated with it at its input or output a time constant circuit 26, 28, 27 of resistors 26, 27 and a capacitor 28 feeding a valve 29 which by its grid base limits negative excursions of the input, the rectifier 25 being so poled that the circuit 26, 28, 27 biasses it to limit positive excursions. Resistor 27 is adjusted relative to resistor 26 until the sliced portion of the carrier lies midway between zero and one half of the pulse peak voltage, since this portion corresponds to minimum distortion of the flanks of the pulse. The time constant of circuit 26, 27, 28 is at least as great as the period of the lowest pulse modulation frequency. Tuned input circuit 24 presents a high impedance to the carrier but low impedance to the derived pulses, which are taken off across an output circuit 30 of valve 29. In a modification a push-pull input to a pair of rectifiers is used. The bias developed across the time constant circuit may be used for A.V.C. of preceding stages.

Abstract: 557,322. Feeding articles from hoppers. NUELL, A. P., and GOLDING, W. F. April 9, 1942, No. 4671. [Class 78 (i)] A machine for feeding discs, washers, pellets &c. into containers comprises a V-shaped hopper 1a formed at its lower end with a slot 2a in which is arranged to reciprocate a slide 3a the upper edge of which is inclined at 4a and channelled at 5a. Discs 10a in the hopper collect in the channel 5a and, at the upward limit of the movement of the slide, are fed into a channel 11a just large enough to receive them and provided with a spring-controlled device 12a for reducing the speed at which they leave the lower end of the channel. The discs are delivered in front of a reciprocating pusher bar 15a, which, on moving from right to left, carries a disc on the tip 16a and delivers it to be held temporarily between spring-pressed jaws 17a, from where it is displaced into a container 20a by a reciprocating plunger 18a. In the absence of a container 20a to receive a disc, the bed member 13a tilts down about a pivot 21a and a lever 22a moves to prevent pusher bar 15a from delivering a disc. For dealing with thicker discs a modified slide 3a and pusher bar 15a are described.

Abstract: 589,926. Rotary internal-combustion engines. GRIFFITH, J. E. Feb. 26, 1945, No. 4800. [Class 110 (ii)] The engine is of the intermittent-abutment type and has two pairs of pistons P, C or Pa, Ca, axially spaced, in a cylinder 20, pistons P, C being secured to rings 39, 37 and the other pair to rings 32, 36. Latching pins 52, 53 alternately hold each pair of pistons stationary, while the other pair moves forward, the relative piston motion being used to suck in working fluid through an inlet port 30, in a rotary valve 24, compress the fluid which is burnt and the exhaust gases pass through a port 31 to an outlet 29. A drive shaft 59 is geared to the valve 24 alternately by gears 72, 73, which have teeth around half the gear-wheel only, and gears 33, 38. Piston-carrying rings 39, 34 have ports 44a, 45a which are controlled by piston movements, and when axially in alignment, allow passage of compressed gas, or burnt products, through the discs. The rotation of shaft 59 is communicated to a cam ring 48 by means of gears 65, 63 and the ring 48 has a groove 49 on each face into which one end of a pin 52 or 53 engages when its respective pair of pistons is released, its other end disengaging from a hole 56 in a fixed end face 21 or 22. The other pair of pistons, at this time, is locked by its latching pin to a wall 21 or 22. The cam-ring 48 moves one-eighth of a revolution while the free pistons move three-quarters of a revolution. The rotary valve 24 is driven from the cam-ring 48 through gearing 68, 70, 71. A carburetter is connected to an inlet 28. A hand-starting handle 77 is provided to turn over the engine. The gear ratios of valve cylinder 24, cam-ring 48 and drive-shaft 59 are 1:1:4. A sparking-plug is carried by the valve cylinder 24. In a modified arrangement, Fig. 18, gears 72, 73, 33, 38 are dispensed with and a shaft 59a is provided with gear teeth 90 meshing with idle gears 87 which in turn mesh with internal gears 86 on a cylinder 24a which is made in two parts. The latching arrangements for alternately coupling the pistons to end walls 21a, 22a vary slightly from those used in Fig. 1.

Title: Improvements in driving and stop motion mechanism for yarn winding and like machines
IPC: B65H63/036
Filed: 1922-02-20
Abstract: 196,140. Morrison, J. W., and Holt, T. W. Feb. 20, 1922. Stop-motions.-Relates to the stop-motion mechanism of unit-head winding-machines having a weighting drum or cylinder, the stop-motion operating to release the belt-tensioning mechanism c<1>, c<2>, Fig. 1, and to brake the spindle-driving pulley a<1>. The pulley a' is driven by a belt b tensioned by a pulley c<2> supported by arms c<1> from a shaft c. Fixed to the shaft c is a lever e, which is held in its normal position during winding by a projection f<2> on an arm f<1> engaging with a projection e<1>. During winding the yarn passes through the eye i<2>, Fig. 4, of a detector i which supports a faller h in a slot in a bar f so as to be clear of the wipers l<1> on a rotating shaft l. On breakage of the yarn, the faller h drops and, coacting with the wipers l<1>, rocks the bar f and with it the drum f<1>, thereby releasing the lever e and the pulley c<2>. At the same time a stud c<4> in a lug c<5> on the arm c<1> releases a ledge d' on a brakelever d fulcrumed at d<2>, and allows a spring d' to force a brake-shoe d<4> into contact with the pulley a<1>. The weighting-drum o is displaced angularly by the growing cheese, and when the cheese is fully wound a stud p<1> on a bracket p trips a lever q which disengages the arm f<1> and stops the machine.

Title: Distortion correcting circuits
IPC: G11B20/14
Filed: 1974-02-04
Abstract: 1449383 Pulse position distortion correction SIEMENS AG 4 Feb 1974 [8 Feb 1973] 05051/74 Heading G4C [Also in Division H3] A pulse position correction circuit detects a pulse that is not correctly centred in its slot and replaces it by a pulse centred in accordance with the average spacing between pulses. The circuit is applied to phase encoded pulses recorded on magnetic tape and read out in a form in which a sudden pulse frequency change occurs, e.g. in which a pulse between the data pulses signals a change in data value. The change in frequency causes the first and last pulses of the higher frequency train to move outwardly and the circuit described detects these pulses and replaces them by correctly timed ones. Thus, in Fig. 1, the incoming pulses LES are delayed in a shift register SCH2 and normally supplied by a logic circuit VK to output LZ. A circuit SA1 detects at 6<SP>1</SP>R an interval preceding the pulse larger than the succeeding interval and at KL the opposite inequality while a circuit MS counts clock pulses during four pulse periods of the lower frequency pulses, divides this by four at DIV to produce the average period and, stores the average at SP. If an inequality is detected at GR or KL the pulse from the shift register delay SCH2 is blocked by the logic circuit VK and is replaced by a pulse timed in accordance with the stored average and spaced from the previous pulse by half or a full period depending upon whether the gap before is shorter or longer than the gap after.

Abstract: 1,057,585. Photographic processing apparatus. EASTMAN KODAK CO. Feb. 10, 1964 [Feb. 12, 1963], No.5461/64. Heading G2A. Processing liquid is applied to a photographic sheet by holding the sheet against the periphery of a rotating drum which dips into a supply of the liquid. In the form shown, a drum 16 having a hollow shaft 18 is rotatably mounted at its ends on bearings 14, 15 in side frames 12, 13. The drum is motor-driven at any suitable speed. Its temperature is maintained at a suitable value by a circulatory water supply from a reservoir 27. The water is heated to a predetermined temperature which is maintained by a thermostat, and then pumped through a conduit 32 into the shaft 18 and thence through perforations 33 into the drum. Overflow from the drum returns to reservoir 27, during which it passes a thermostat connected to a gauge 36. A tray 43 for the processing liquid can pivot on a rod 38 from an operative position (shown in full lines in Fig. 2) to an inoperative position (shown in dotted lines), and can be held by detent means in either position. A blanket 44, of some such material as nylon net or cloth, has a weighting bar 46 at one end, which may be secured by a latch 47, the blanket lying round the drum. The sheet to be processed is wetted, to increase its surface tension, and then held against the surface of the drum by the blanket, the said surface tension being sufficient for the sheet to be held stationary by the blanket as the drum rotates. Developer solution is poured into the tray 43, only a small quantity being required since the tray is shaped to fit round the drum with only a small clearance. The developer solution in the tray can then be replaced by wash water and/or further processing solutions. The blanket may be provided with perforations, Fig. 6 (not shown), to allow the back of the sheet to be washed when processing is completed.

Title: Improvements in method of making di-chloramine
IPC: C01B21/09
Filed: 1932-02-24
Abstract: Di-chloramine is obtained, in admixture with varying proportions of mono-chloramine, by the reaction of available chlorine on ammoniacal material, either in the presence of a difficultly soluble compound adopted and in sufficient quantity to retain the pH between 4.4 and 8.5, or in the presence of a base adopted and in a quantity sufficient to absorb the major part of the acid liberated and a buffer to absorb the remainder of the acid and retain the pH between 4.4 and 8.5.  The chlorine may be used in the form of free chlorine or hypochlorous acid.  The ammoniacal material may be free ammonia or ammonium salts such as the chloride or sulphate.  The difficultly soluble compound or buffer may be a difficultly soluble phosphate such as the di- or tri-basic phosphates of calcium, barium or magnesium; soluble buffers such as sodium phosphate may be employed when hypochlorous acid is used and/or when a base is employed to absorb the major part of the acid.  The bases referred to are calcium and magnesium hydroxides and carbonates, and soda ash.  Soluble bases such as soda ash should be added gradually.  The process may be used for the production of dilute solutions of di-chloramine for use in the sterilization of water.  According to an example such a solution is prepared by adding a mixture of ammonium chloride, calcium carbonate and di-calcium phosphate to water in a tank provided with stirring means, a dilute solution of hypochlorous acid obtained by treating chlorine water with limestone being subsequently run in.
