Title: Improvements in or relating to electrical compandor circuits
IPC: H04B1/64
Filed: 1955-06-10
Abstract: 804,802. Automatic volume control. PHILIPS ELECTRICAL INDUSTRIES Ltd. June 10, 1955 [June 15, 1954], No. 16747/55. Class 40 (4). In a compandor system having expansion or compression circuits comprising variable attenuation networks in the signal circuit and in the compression or expansion control circuit to give a fixed ratio, the networks are controlled jointly at each station by a voltage obtained by rectifying a portion of the transmitted signal and equality of network attenuation is maintained by an additional control signal derived by comparing the outputs of auxiliary signals passed through the network. In the compressor, Fig. 1, networks 3, 14 are both controlled in accordance with the difference between the rectified signal voltage across condenser 29 resulting from the output of amplifier 4, and a constant reference voltage applied at terminal 18. Network 3 is controlled additionally by the output of a difference producer 37 to which auxiliary current outputs from the networks are applied over coils 30, 31. The auxiliary currents which are chosen with frequencies above the intelligence band are applied to the networks over windings 33, 34 and are blocked from the transmission and control paths by filters 39, 40. The auxiliary signal control voltage is added to the main control voltage in a circuit 38 of small time constant. The application of auxiliary equalizing currents to the control networks of an expander of the type described in Specification 804,801 is described with reference to Fig. 2 (not shown).

Title: Improvements in or relating to tandem rocket launchers
Inventor: GRAHAM CONNELLY LOWRY
IPC: B64D1/04
Filed: 1955-06-13
Abstract: 772,884. Launching rockets from aircraft. NORTHROP AIRCRAFT, Inc. June 13, 1955, No. 16994/55. Class 9 (2). A rocket housing and launching device comprises pods 2 fitted at the wing-tips of aircraft and each containing three launching tubes 6 in which the rockets R1, R2, R3 ... are arranged in tandem, each pod being closed at the forward end by a transparent frangible cover 4 which is ruptured by the first rockets fired from the device. To protect the intermediate rockets from the propellent gases of the preceding rockets, each tube is provided with enlargements forming exhaust chambers 7 which surround the rocket nozzles. In each chamber is a pivoted baffle 10, which diverts the exhaust gases into a channel 12 communicating with ports 13 in the pods 2. On each baffle is an electric igniter 15 connected by leads 16 and 17 to the control within the aircraft. The leads 17 are also connected to a solenoid 20, which withdraws a pin 21 from the rocket simultaneously with firing of the igniter. Each baffle 10 is connected by linkage to a bell-crank 30 which has an arm 33 projecting into the tube 68 carrying a roller 29 which is thrust laterally by a rocket R2 moving forward in the tube. Movement of the roller 29 swings the bell-crank and, through the linkage, pivots the baffle 10 out of the path of the rocket. At the same time a catch plate 41 is moved until a spring 43 engages a notch 42, thus locking the baffle in the inoperative position. The gases from the rearmost rocket are exhausted through an elongated port 50 in the pod 2. In a modification, Fig. 5, the baffles are deflected by the exhaust gases. Each channel 12 is normally closed by a hinged flap 60 connected by linkage to the baffle 10 for the next preceding channel 12, the linkage being also connected to a positioning pin 67. Thus as the rocket R2 is fired, the exhaust gases pivot the flap 60 which through the linkage withdraws the pin 67 and moves aside the preceding baffle 10. A catch 70 keeps the flap 60 open after firing.

Title: Improvements in and relating to the preparation of organohalogenosilanes
IPC: C07F7/16
Filed: 1947-06-27
Abstract: Organohalogenosilanes, in particular those containing a hydrogen atom directly attached to silicon, are prepared by reacting at an elevated temperature a hydrocarbon halide and the silicon component of a mass comprising silicon and a halide of copper.  The temperature range may vary between 200 DEG  and 500 DEG  C. The copper halide may comprise from 5 to 60 per cent by weight of the silicon-copper halide mass. Suitable halides of copper are cuprous or cupric halide, e.g. cuprous and cupric chlorides, bromides and fluorides.  The hydrocarbon halide may be an alkyl, aryl, aralkyl or alkaryl halide, particularly a chloride or bromide.  In examples: (1) and (2) methyl chloride is passed over heated silicon and cuprous chloride to yield methyl dichloro-, dimethyl dichloro- and methyl trichloro-silane.  The process may be used to prepare other alkyl halogenosilanes, e.g. methyl, ethyl, propyl, butyl, amyl or hexyl halogenosilanes, aryl halogenosilanes, e.g. phenyl halogenosilanes, aryl-substituted aliphatic halogenosilanes, e.g. phenylethyl halogenosilanes, aliphatic-substituted aryl halogenosilanes, e.g. tolyl halogenosilanes.  Organohalogenosilanes containing a hydrogen atom directly attached to silicon may be alkyl halogenosilanes, e.g. methyl, ethyl or propyl dichlorosilane, arylhalogenosilanes, e.g. phenyl dihalogenosilanes, for instance by the reaction of a monohalogenated benzene such as chlorobenzene and silicon in the presence of a copper halide, aryl-substituted aliphatic halogenosilanes, e.g. phenylethyl dihalogenosilanes, aliphatic substituted aryl halogenosilanes, e.g. tolyl dihalogenosilanes. Specifications 572,740, [Group VIII], 575,657 and 585,947 are referred to.
