Title: Improvements in or relating to television transmission systems
Inventor: WHITE ERIC LAWRENCE CASLING
IPC: H04N3/16
Filed: 1949-05-19
Abstract: 666,289. Television. ELECTRIC & MUSICAL INDUSTRIES, Ltd. May 5, 1950 [May 19, 1949], No. 13336/49. Class 40 (iii). In a television transmission system in which recurrent datum level signals interspersed with the picture signals are caused to assume a fixed level (i.e. D.C. re-insertion) and in which shading signals are mixed with the picture signals prior to D.C. re-insertion, the shading signals are provided, during the recurrent intervals, with portions of fixed level exceeding the amplitude of the shading signals and which are unaffected by changes in the amplitude of the latter signals. With this arrangement the amplitude of the shading signals may be adjusted without affecting the re-inserted D.C. level. The invention is described as applied to a system in which the scanning cathode-ray beam of the picture signal gener. ating tube is suppressed during " fly-back " periods so that signals related to the black level are produced. In the arrangement shown in Fig. 2 the outputs of the shading signal generators comprising line " tilt " and " bend " generators 1, 2 and frame " tilt " and " bend " generators 3, 4 respectively are fed via variable resistances 33 ... 36 to a mixer and limiter 42 to which pulses 43, of amplitude greater than the maximum amplitude of the shading signals and which occur during the recurrent intervals, are applied. The level 45 at which limiter 42 operates is arranged to be intermediate the maximum amplitudes of the shading signals and the added pulses so that portions of fixed amplitude are introduced, the level remaining fixed despite variations in the amplitude of the shading signals which it may be necessary to make during operation. The output from 42 is thus fed to a further mixer 46 to which auxiliary signals 47, recurrent at the frequency of the pulses 43, are applied (to shift the level of the fixed amplitude portions to a required value prior to D.C. re-insertion as described in Specification 515,360) and then combined with picture signals from source 37 the combined signals, after amplification at 38 being fed to a D.C. re-inserter 39. Specifications 442,666, 449,242 and 508,377, also are referred to.

Abstract: 717,072. Honeycomb paper; compound sheet materials. CALIFORNIA REINFORCED, PLASTICS CO. May 28, 1952, No. 13540/52. Classes 96 and 140. A honeycomb structure is made by applying lines of adhesive 10a and 10b on opposite sides of a web 18 of flexible material drawn from a roll 17 with the lines on opposite sides out of register, and lapping the adhesive-coated web upon itself to build up a stack of superposed layers, e.g. on a horizontally-reciprocating table 31, while continuously applying pressure to the stack along its whole length, e.g. by two systems of travelling belts 46 running around rollers 42, 43 and 44 mounted in fixed bearings, and 46a running around a similar set of rollers 42a, 43a and 44a. The belts 46, 46a, which are out of register with one another and with the lines of adhesive on their side of the web, are pressed against the top of the stack by freely rotatable rollers 45. The adhesive lines are applied by discs 26 on a driven shaft 25 which are fed by a driven roller 23 dipping in an adhesive trough 22 and may be partly dried, e.g. by infra-red lamps in a casing 27. The adhesive-coated web is drawn downwardly towards table 31 by co-operating discs 54, 54a on driven shafts 53, 53a. To accommodate the growing stack, table 31 is spring-mounted on a carriage 15, which is constrained to move horizontally by sets of rollers 13 and 14. The carriage is reciprocated by a driven cog 36 which acts on a rack 35 attached to the carriage, and is periodically reversed when one of two lugs 66, 67 on the carriage strikes reversing lever 65. A second rack 52 attached to the carriage causes rotation of cog 51 and hence of belts 46. The flexible material, which may be impregnated with phenolaldehyde resin, may be paper, cloth, glass fabric, or aluminium foil. The material is used as a lightweight core in laminated panels, bulkheads, or fuselage walls.
Patent GB-135852-A (GB)
IPC: F01L7/08
Abstract: 135,852. Sinclair, A. C. Aug. 6, 1917, [Convention date]. Valves; valve-gear. - In a four-stroke cycle engine having a main valve of the rotary or oscillating type controlling exhaust or both inlet and exhaust and held against its seating by the pressure in the cylinder, a supplementary exhaust port is uncovered by the piston towards the end of the power stroke so as to relieve the pressure on the main valve, which is stationary whilst under pressure and moves only after the pressure has been reduced. In the engine described, the exhaust gases are discharged through terminal ports 60, air compressed in a pair of crank chambers is admitted through terminal ports 61 before the ports 60 close, scavenging the cylinder and cooling its walls, and this air is discharged through a valve 47 in the cylinder head. The scavenging-air is admitted to the crank chambers of the pairs of cylinders 1 and 4, 2 and 3 respectively through ports 73, 73<1> in a rotary cylindrical valve 65, Figs. 4 and 25, driven at half the speed of the crank-shaft. The crank chambers of a pair may communicate directly, or through the valve as shown. The admission or scavenging-air to the cylinder ports 61 from each pair of crank chambers to each of the two corresponding cylinders in turn is controlled by the parts 71 of the valve. The discharge of the scavenging-air from the working cylinder and the admission of the new charge are controlled by the oscillating conical valve 47, Fig. 25, which has alternate inlet and exhaust ports opening to the chamber 40 and the casing 46 respectively. The valves 47 are worked by grooved cams on an overhead shaft driven at one-half the speed of the crank-shaft through a countershaft 56, Fig. 2, and the valves are stationary during the compression and power strokes and until the cylinder pressure has been relieved by the opening of the terminal ports 60. The terminal exhaust ports 60 may be controlled by a cylindrical valve 80. Fig. 13, rotated from the countershaft 56 through spur gearing at one-third or other odd fractional part of the speed of the air valve 65. The scavenging-air discharged from the cylinders through the valve 47 passes through the casings 46, 90 of the valve-gear and thence through the hollow interior 91 of the exhaust-valve 80 into the exhaust pipe 88, exerting an ejector action and cooling the exhaust. The sparking-plug is mounted centrally in the valve 47.

Abstract: 377,338. Coin-freed apparatus. NAAMLOOZE VENNOOTSCHAP GENERAL HOLDING CO., Wassenaar, Holland. May 11, 1931, No. 13935. Convention date, May 10, 1930. [Class 27.] Testing coins ; returning coin ; coin action, weight ; delivery of articles stored in piles.--In a coin testing and releasing mechanism for coin-freed apparatus which separates under and over weight coins from those of correct weight, a coin inserted through a slot 2, Figs. 1 and 2, passes down a shoot 1 and falls into a weighing device 5 rockably mounted by means of a clamping plate 11 engaging a steel band to a pendulum arm 6 pivoted at 7 to a bracket 3. The pendulum arm 6 allows correct weighing of the coin if the apparatus is inclined. The weighing devices comprise a counterbalance weight 12 and a channel having a fixed side 13 and a resiliently mounted side 15 provided with a slot 16 through which a pawl 17 connected to the arm 18 of a bell-crank lever 18, 23 can pass when a coin 14 of correct weight is in the device 5. Excessive oscillation of the weighing device, when it receives a coin, is prevented by a baffle 31 carried by it working in an oil or air dashpot carried by the arm 6. The pawl 17 has a narrow portion 17a and a broad portion 17b forming shoulders with the part 17a. The portion 17b can pass through the slot 16 only when the weighing device contains a coin of correct weight. In the case of light or heavy coins, either the lower or upper shoulder of the pawl catches the edge of the slot. The bell-crank lever 18, 23 is pivoted at 19 to the bracket 3 and held in the position shown in Fig. 2 by a coiled spring 20. An arm 21 is also pivoted at 19 and held'raised by a blade spring 24 connected to the arm 18 and stronger than the spring 20. When a drawer or slide 25 is pulled out to deliver an article, a projection 26 thereon depresses the arm 21 and moves the bell-crank lever so that the portion 17b passes through the slot 16. When the drawer is fully withdrawn, an abutment 30 opens the side 15 and the coin drops to a money box 39. If the coin is of incorrect weight, the pawl 17 is caught in the slot 16, and the arm 21 is depressed against the action of the spring 24 so that the projection 26 engages teeth 22 in the lever arm 23 and the drawer cannot be withdrawn further. The slight movement of the drawer opens the side 15 and the incorrect coin dropping out is directed by a guide 41 on the arm 18 and a second guide 42 to a return space 40. A blade spring 35 acts against a roller 36 to assist the return of the drawer. The testing mechanism is mounted on a baseplate which is readily removable for the mechanism to be inspected. The drawer may be locked by several weighing devices each for a, coin of a different denomination. Coin-slit closing-devices.-When the drawer is pulled out, a stop 27 thereon disengages a resilient arm 28 and allows a plate 33 to close the end of the shoot 1.
