Title: Improvements in and relating to recording systems
IPC: G01D9/34
Filed: 1946-01-17
Abstract: 608,261. Frequency modulation; thermionic valve circuits. BRITISH THOMSON-HOUSTON CO., Ltd. (General Electric Co.). Jan. 17, 1946, No. 1652. [Classes 40 (v) and 40 (vi)] [Also in Groups XIX and XXXVIII] A recorder 13, Fig. 1b, moves to successive positions corresponding to a plurality of quantities, and is prevented from recording while moving, by developing from the deflecting potential a bias to cut off a valve 28. The invention is described with reference to a radiosonde transmitting signals modulated in frequency according to temperature, pressure and humidity. At the receiver, the signals are applied to a frequency discriminating circuit 10, Fig. 1b, feeding a meter 11. A follow-up device 12 positions a recorder 13, and the follow-up signals are applied over diode 16 to triode 18a, so that when the follow-up signalis zero, the potential at 19a is zero, but when the follow-up signal is negative, the potential at 19a is positive, thus applying positive potential to grid of valve 23. If the follow-up voltage is positive, the grid of valve 23 gives positive over diode 17. A positive potential on valve 23 results in a cut-off negative bias on valve 28 so that the recorder 13 is inoperative except when the follow-up voltage is zero. In a modification, the follow-up signal actuates a relay to complete the circuit of a diode rectifying A.C., thus driving the grid of valve 28 to cut-off, Fig. 2 (not shown). Transmitter.-Resistances 5, 6, 7, Fig. 1a, are varied in accordance with temperature, pressure and humidity and, together with a reference resistance 8, are successively connected to earth by switch 4 so as to form with condenser 3 R.C. circuits of different time constants to determine the blocking rate of blocking oscillator 2 modulating transmitter 1.

Filed: 1937-01-20
Abstract: 489,176. Moulding sliding-clasp fasteners. CORNER, G. H. C., and IMPERIAL CHEMICAL INDUSTRIES, Ltd. Jan. 20, 1937, No. 1754. [Class 87 (ii)] [Also in Group XXV] For the manufacture of sliding-clasp fasteners there are used strips of integrally connected elements formed by moulding or casting or plastic deformation of plastic non-metallic material. The strip of integrally connected elements shown in Fig. 3, is formed in the drum mould shown in Figs. 1 and 2, the moulding recesses comprising portions 2 to form the interlocking projection parts 3 and portions 5 to form the leg or base parts 6 ; the segmental covers 9 have core projections 10 to form the usual interlocking recesses in the elements and have channels 14 by which the moulding material fed through axial and radial ducts 12, 13 passes to the moulding recesses 2, 5. The drum has steamheating and water-cooling passages. When the moulding is completed the cover segments 9 are moved away, the material indicated at 17 as arising from the channel 14 is trimmed off, and the strip of elements integrally connected at their leg portions is pulled off the drum. The drum recesses may be helically arranged so that a long length of integrally connected elements is obtained; the arrangement in this case may be such that the longitudinal edges of the strips are connected and that the connected strips are removable in the form of a cylinder convenient for storage, the strip of elements, when required, being obtained by a cutting action as in screw cutting. A strip of elements connected as shown in Fig. 6, may be obtained by the injection mould shown in Fig. 5. The strip of elements may be obtained by the action of heated dies on a strip of material. Specifications 391,146 and 444,405, [both in Group XXV], are referred to.

Title: Sound, flame and recoil subduing apparatus for automatic fire arms
IPC: F41A21/30
Filed: 1928-01-20
Abstract: 289,420. Wilman, Z. April 27, 1927, [Convention date]. Machine guns. - Relates to sound, flame, and recoil subduing devices comprising a chamber at the muzzle of the gun into which the gases expand before leaking out, and consists mainly in the provision of a double closure for preventing the escape of gas through the exit hole for the bullet and the return of gas to the barrel. In the form shown in Fig. 1, when a shot is fired, the bullet from the barrel 1 passes through a small chamber 3, an orifice 19, a main chamber 5, and an outlet 20. The gases expand into these chambers, and the pressure in the small chamber 3 operates a piston 18, which bears on an arm 11 and rocks a lever 8 pivoted at 7, thereby closing the orifices 19, 20 by means of balls 9 on pivots 10 on the ends of the lever 8. The arm 11 has a hole 12 for the passage of the bullet. The closing movement is allowed by the recoil of the barrel 1 relatively to the chambers, which are attached by a socket 2 to the radiator of the gun. When the barrel subsequently runs out, it bears on a transverse bar 15 connected by rods 13 to the lever 8, and returns the lever to the open position shown. In one modification, the lever is returned to the open position by a spring plunger at the front end of the chamber 5. In another modification, Fig. 5, the chamber containing the lever 38 has a rear extension 29 enclosing a barrel extension 31 having radial holes 30 covered by a correspondingly perforated sleeve 33 interposed between a rear spring 35 and the lever 38. The gas pressure moves the sleeve 33 to the rear, closing the various orifices; and the spring 35 returns all the parts to the open position when the gas pressure has subsided. In a further modification, Fig. 6, the gases are deflected by a " funnel " member 42 through orifices 44 and are trapped in the chamber 43 by rear and front valves 39, 40 interconnected by links 46. The valves, are closed by the gas pressure, and are re-opened by the gun barrel 45 when it subsequently runs out. The Specification as open to inspection under Sect. 91 (3) (a) describes also another modification, shown in the closed position in Fig. 8 (Cancelled). In this modification, the member which closes the outlet 50 is in the form of a ball 47, which turns about a pivot 49 while it slides backwards and forwards. A passage 48 through the ball is in line with the barrel in the open position. This subject-matter does not appear in the Specification as accepted.

In a colour television camera relatively narrow-band signals corresponding to lowdefinition colour and luminance information are produced by a plurality of different colour pick-up tubes each corresponding to a different primary colour image and these signals are supplemented with wide-band high-definition signals complementary thereto derived from a luminance pick-up tube. Fig. 1, of the drawing accompanying Provisional Specification (not shown), depicts one arrangement in which signals derived from pick-up tubes for the primary colours R (red), G (green) and B (blue), and which tubes may be of comparatively poor quality, are fed via respective low-pass filters, to gamma-correcting circuits RGC, GGC and BGC together with signals derived from a highquality luminance pick-up tube Y and fed via a high-pass filter YHP the pass-band of which is complementary to that of the low-pass filters. In a modification of this arrangement the green pick-up tube is not employed, the green signals being derived by a known matrixing technique (Fig. 2, Provisional Specification, not shown). A preferred arrangement is shown in the drawing accompanying Provisional Specification 29567/64, where the outputs of the low-pass filters are combined in a matrix M 1  in the proportions 0À3 RN+0À59 GN+0À11 BN to produce a narrow band low-definition signal YN which is then subtracted from the wide-band luminance signal YW to produce the required complementary signals YD for combination with the low-definition signals at the inputs to the gamma-correcting circuits.

Abstract: 1330284 Monitoring multiple spindle textile machines S PEYER 14 Jan 1971 [14 Jan 1970] 1959/71 Heading D1F [Also in Division G1] A system monitoring a multiple head machine, with a switch (S1, S2.. Sn) for each head closed or opened to indicate that the head is running or stopped, comprises a charging circuit JG associated with the switches for charging a capacitive reactive element C with an electric current, the size of which is related to the number of machine heads operating at any instant, and a discharging circuit SE for discharging the element c when a predetermined charging level has been reached and, upon such discharge, supplying an output pulse to provide a series of pulses which are spaced from each other in dependence on the number of switches closed, to form a measure of the time integral of the heads in operation. A resistor Ro is placed in series with each switch S and all the switches with their series resistors are placed in a parallel circuit so that when all the operating heads are functioning properly a certain equivalent impedance RN will result in the parallel circuit. The discharge circuit SE includes a threshold detector whereby the capacitor C discharges when, a predetermined charge level is reached. The output pulses from terminals F, O after passing through certain time units Um are counted and the total in a store represents the time integral of operating heads which may be compared with real elapsed time to provide a measure of efficiency. The heads may be monitrode in groups and the efficiency of the groups may be recorded individually in sequence for example at the end of each hour. The elapsed time clocks for each machine or group of heads may be synchronous clocks or each clock could be a circuit similar to that shown in Fig. 3 but with the input terminals A, B, connected at a single fixed resistor of suitable value corresponding to the equivalent resistance RN when all switches are closed so as to provide a fixed number of clock output pulses per unit time, e.g. a thousand pulses an hour. The machine may be multiple spindle spooling machine with the switches operated by running threads.

Title: Improvements in and relating to a method of and means for producing relief maps, charts, models and like substantially flat articles
IPC: G09B29/12
Filed: 1935-01-24
Abstract: Flexible relief maps, charts, placards, models, and like substantially flat articles are prepared by subjecting a thin layer of rubber composition having a fabric backing to pressure between positive and negative moulding surfaces while heated to effect vulcanization, whereby the rubber composition permanently acquires the form of the mould surfaces without losing its flexibility.  From an original plaster or like cast a matrix is made in aluminium, chrome bronze, or other metal, which is then worked or engraved to the desired configuration.  A counter-mould is prepared from the metal matrix, with the necessary clearance to receive the rubber material.  A layer of rubber mixed with kaolin, on a fabric backing, is applied to the matrix, and heavy pressure is then applied by the counter-mould, at a temperature of approximately 140 DEG  C., to vulcanize the rubber and attach it firmly to the fabric backing. Coloured products may be obtained by incorporating dye in the rubber composition.
