Title: Telephone and like transmission systems
IPC: H04B3/20
Filed: 1938-06-24
Abstract: 504,169. Two-way transmission. STANDARD TELEPHONES & CABLES, Ltd. June 24, 1938, No. 18798. Convention date, July 22, 1937. - [Class 40 (iv)] In a four-wire transmission system having paths for signal transmission in opposite directions between two stations, means, governed by the voice currents on an active path are provided for transmitting a tone over the idle path. The attenuation of the idle path is controlled solely by this tone. Two stations 3 and 4 are joined by an east to west line' 2 and a west to east line 1, the two lines being connected through hybrid coils to two-wire circuits 6, 7 and 9, 10 at the east and west stations respectively. A signal along the line 2 operates a series of relays 84, 85, 86, 87 and 82, through an amplifier detector 83, the relay 87 short-circuiting the west to east path at station 4 and the relay 82 removing a short circuit from the control circuit for the loss device 48 in the line 1. The signal passes through an amplifier 13, a pad 14, a loss device 15, and amplifiers 18 and 19, and operates relays 68, 71 and 72 through an amplifier 66 to short-circuit line 1 at station 3 and to apply a source of A.C. 73 within the voice frequency range to the line. This tone is amplified at 77 and controls the bias on the grid of a valve 80 which supplies current to the loss device 48. A condenser 79 between the grid and cathode of the valve 80 is arranged to be positively charged through a cold cathode gas-filled discharge device 102 by means of a battery 106. The condenser is negatively charged through the discharge device 100 by means of the battery 98. Charging only takes place when one or both of the discharge devices are broken down, this being effected by the amplified tone signals which are applied to the control electrodes 95, 96 and 103, 104 in devices 100, 102 respectively. The device 100 is broken down by any tone and tends to lower the loss effected in device 48. The discharge device 102 is only broken down to increase the loss in the device 48 when the tone gets too strong. The loss in line 2 is similarly controlled when line 1 is in use.

Abstract: 790,679. Controlling change-speed gearing. COMPAGNIE DE PONT-A-MOUSSON. June 19, 1956 [June 20, 1955; May 12, 1956], No. 18917/56. Class 80 (2). In an hydraulically-actuated constant-mesh change-speed gear A for a motor vehicle, the liquid supply pipe 1 from an engine-driven pump E to the manual control piston valve 10 has a branch 69 leading to an exhaust piston valve 48 subjected, in opposition to the pressure in the branch and through a spring-loaded plunger 43 in series with a spring 53, to the liquid pressure in a cylinder 122, this pressure being controlled by a centrifugal governor 76, driven from the driving shaft C and fed from the pipe 1 through a branch 70 and delivering through a pipe 84, so as to increase with the speed of the driving shaft C whereby the exhaust valve 48 closes progressively as engine speed increases and pressure builds up progressively in the system at starting of the vehicle. The apparatus shown is the same as that in Fig. 1 of Specification 757,169, comprising a main exhaust piston valve 48 for the branch 69 and an auxiliary exhaust valve 66 controlled by a spring-loaded valve 37 opened momentarily during movement of valve 10 from any gear position to another so as first to exhaust the chamber 122, which is supplied from pipe 1 through an adjustable needle valve 60, and then allow the pressure in chamber 122 to build up again, with the addition of a further exhaust valve 93 which is controlled by the pressure in pipe 84 and which successively connects to exhaust, as the engine speed increases, a series of longitudinally-spaced passages 90 leading from the chamber 122. In a simplified form, the auxiliary exhaust valve 66, its control valve 37, the adjustable valve 60 and the further exhaust valve 93 are all dispensed with and the chamber 122 is supplied by the pipe 84 instead of by the pipe 1.

[Also in Group XXXII] A heat-insulated motor vehicle body, in which CO 2  may be distributed about the interior of the body (see also Group XXXII), and Figs. 1 and 2, has an opening 3 which may be closed by a hinged flap 4, a sector-shaped canopy 9 having a ceiling and side walls 10 hinged at 8, and a flap 11 which is upwardly spring-biased to close the bottom of the canopy 9 when the body is not being unloaded. A user wishing to enter the body or chamber first hinges down the flap 4 to the Fig. 2 position and then sits upon it so that he may depress the flap 11 with his feet, at the same time pulling the canopy over his head until its rim engages with the flap 4. Goods loaded through flaps 15 into insulated holders 14 may be removed from outside the body by opening doors 13, and a pullout holder 16 having a door 19 may be loaded through openings 17 and 20. In a modification, Figs. 4-7 (not shown), the insulated side holders may be extended upwardly to define a central aisle and the flap 4 is omitted, the canopy 9 merely engaging either the flap 11 as before or a base member forming part of an extension of the body. Side loading flaps may be provided in the external and internal body walls. In a further modification, Figs. 8 and 9 (not shown), internal loading flaps giving access to the insulated holders are linked to a movable barrier which prevents the user from leaving through the exit 3 whilst the loading flaps are open. Alternative forms of mechanical or electrical interlocks may, however, be employed to prevent ambient air in quantity from entering the main portion of the body.

Title: Improvements relating to crimping or pleating
IPC: D06J1/06
Filed: 1947-07-16
Abstract: 627,367. Pleating. PILLINER, B. J. July 16, 1947, No. 19012. [Class 141] [Also in Group XXII] In a method of and machine for pleating materials such as thin metal sheet, metal gauze, woven textile and other materials, blades are moved angularly into engagement with the material alternately from opposite sides of the material, each blade picking up the material and carrying the material with it until the blade has been brought into a position substantially parallel to the preceding blade with a length of material between the two blades, the blades being moved forwardly with the pleated material and the parallel series of blades being simultaneously moved out of the formed pleats towards their respective sides of the material and permitted to remain parallel until free of the finished pleated material. In the embodiment described, the material is fed from a table 13, Fig. 1, through tension rollers 14 to a region between a pair of rotary members each comprising a pair of circular flanges 20 mounted upon one of the shafts 1, 2, between which flanges are pivotally suspended a plurality of blades 3. The shaft 1 is driven in a clockwise manner, a spring 7 preventing the blades on their downward movement from turning under gravity to a vertical position, and the shaft 2 is driven in an anti-clockwise manner. A pair of levers 4, 5, loosely mounted upon the shafts 1, 2 are rocked by a crank 11, whereby spring-loaded pawls 6, Fig. 4, are engaged alternately behind the blades of the upper and lower rotary members which in turn are alternately impelled to a vertical position, pleats of the material being formed therebetween. The blades are urged by the levers 4, 5, to a position beyond a pair of spring loaded check pawls 21, which thereafter prevent backward movement of the blades. Subsequent to the pleating operation, the blades move forwards and outwards whilst remaining in parallel relationship, the pleated material being directed by guides 18 into a box 15 against a spring-loaded bar 17. The pleats may be tensioned by advancing the point at which the blades complete the folding operation so that they slidably increase their overlap after the pleats have been formed, this being effected by adjusting the position of the check pawls 21, the throw of the crank 11 and the angle of set in the arms 4, 5.

[Also in Group XL (c)] In triggering apparatus for a gas tube which generates luminous flashes for use in a stroboscope as described in Specification 686,092, in which a pulse train is applied to a valve to render it alternately conducting and non- conducting to trigger the tube, a capacitor connected across the tube has its rate of charge controlled by a further valve to prevent premature firing of the tube. In the Figure the gas tube 1 is triggered by pulses derived from the multivibrator comprising valve 6, the " squarer " stage 9 and the trigger stage 2. Capacitor 4 is charged from the E.H.T. supply via resistor 8 and valve 3 at a rate determined by the control grid potential of this valve so that when valve 2 is conducting and tube 1 is discharging the control grid potential of valve 3 is low and the charging rate is low, the voltage across the capacitor at first rising and then remaining constant. When a negative going pulse at the grid of valve 2 renders it non-conducting, the potential on the grid of valve 3 rises and capacitor 4 charges rapidly to its maximum value, Fig. 4 (not shown). The multivibrator may have its " mark-space " ratio adjusted by resistor 7 or it may be replaced by a triggered " flip-flop circuit, Fig. 3 (not shown).

Abstract: 533,014. Feeding sheets. BATTEY, A. P., and BACKHOUSE, H. T. July 3, 1939, No. 19347. [Class 100 (i)] In sheet-feeding mechanism of the kind in which the sheets are registered laterally by a reciprocating suction or mechanical sheet gripper movable to and from a fixed side leg, the reciprocation of the gripper is effected by means of a closed fluid-containing pipe, e.g., a flexible pipe 6, Fig. 1, connected to a cylinder 7 fitted with means for varying the fluid pressure in timed relation with the operation of the sheet feeding mechanism. This pressurevarying means may comprise a piston 8 moved in one direction by a cam 10 and in the other direction by a spring 12. The suction gripper 1 is connected to a piston 2 in a cylinder 5 to which the pipe 6 is secured. The gripper 1 may be replaced by a gripper of the kind described in Specification 485,252, and the grippers may be moved either to or from the side lay 19 by the fluid pressure and returned by spring means. Also diaphragms may replace the pistons, and in one modification suction may be used to effect or assist in effecting the movements of the sucker in one direction. The invention is applicable to machines as in Specification 427,041. Specification 464,873 also is referred to.
