Title: Sound reproducing means
Inventor: LICITIS GUNARS
IPC: G11B33/06
Filed: 1969-08-13
Abstract: 1,208,537. Playback of grooved tape sound records. M. I. GLASS, [trading as MARVIN GLASS & ASSOCIATES]. 13 Aug., 1969, No. 40513/69. Heading G5R.  A tape 34 having a plurality of generally parallel sound grooves (36, Fig. 5) thereon is secured at one end to a reel 38, which is rotatably mounted in a housing 12 and is biased by a spring 68 to wind the tape on to the reel, the free end 43 of the tape 34 extending through an opening 40 in the housing 12 which carries also a vibratable diaphragm 22 connected to a stylus 30 which engages the tape 34 as the latter is being pulled out of the housing 12. The application of tension to the tape 34 causes rotation of an arm 42 about its pivot 82, in opposition to a spring 94, and consequent pressing of the tape against the stylus 30 by a spring-biased pressure pad 44. The opening 40 is wider than the tape 34 which may therefore be moved laterally to select the groove to be engaged by the stylus 30.

Title: Improved manufacture of vinyl esters
Inventor: BEESLEY STANLEY
IPC: C07C67/055
Filed: 1964-10-06
Abstract: In the process for making vinyl esters by circulating at an elevated temperature a liquid solution of a palladium (II) carboxylate, a metal salt capable of oxidizing palladium metal and an alkali metal salt of a carboxylic acid, dissolved in a carboxylic acid, through two zones, bringing the solution into contact with ethylene (which is in excess of any molecular oxygen which may be present) in one zone and into contact with molecular oxygen in the second zone whereby the vinyl ester is formed with the simultaneous reduction of the palladium carboxylate to palladium metal, part of which is precipitated, and heating the precipitated palladium with a carboxylic peracid to form a palladium carboxylate.  The process provides a method for oxidizing with peracid any reduced palladium salt which has not been oxidized by the redox system provided by the metal salt which may be, e.g. a cupric or ferric salt.  The peracid oxidation may be effected by separating the precipitated palladium from the reaction prior to oxidation or by forming the peracid in situ, by supplying acetaldehyde to either or both zones, and oxidizing the palladium in situ.  An example describes the preparation of vinyl acetate, using peracetic acid to oxidize the precipitated palladium.

An external and internal locking system for a structure having two or more doors, comprises a control lock for one door, a controlled lock for the or each other door, and electromagnetic control means by which the controlled lock or locks can be operated from the control lock, each door having both an external and an internal locking arrangement with independent locking action without operative interconnection, so that neither arrangement can be unlocked by operation of the other, whilst either can be brought into the locking position independently of the other. As shown, the invention is applied to the four doors 1, 2, 3, 4 of a vehicle each of which is provided with a latch device 5 operable by a catch or handle 10 against a spring 7 which also loads the latch device 5 in its locking position corresponding to its full engagement in a keeper socket 6. In this position the latch device is lockable by an internal locking element 12 and, or, by an external locking element 13, the elements 12, 13 being engageable in a single or a pair of bores 11 in the latch device. The element 13 of the control door 1 is actuated by a central lock-actuating part 20 to which is coupled a switch 21 in an electrical circuit which includes solenoids 24 for simultaneous operation of the elements 13 of the other doors, the arrangement being such that the latch devices can only be locked when the elements 12, 13 are aligned with the bores 11. In another arrangement Fig. 3 (not shown), the latch bolt of the latch device is slidable against a spring (50) relative to the rest of the device to permit locking prior to the door being latched.

Abstract: 960,108. Calculating machines, setting &c. mechanism. TRIUMPHATOR-WERK VEB. Nov. 30,1960, No.41166/60. Heading G4B. In a calculating machine each type wheel setting segment is controlled, through a transmission lever, by the pin carriage and releases a latch from the type carriage which is still retained by a holder until all the segments have been set, when printing can take place. The segment 3 rotates about a shaft 31, causing a transmission lever 5, attached by a pin 4 and pivoting about a fixed pin 6 in a slot 7, to detect a set pin in the pin carriage 1. The rotation of segment 3 sets, via transmitting wheel 10, a type wheel 11 accordingly and also releases a spring- urged latch 14 from the type carrier 19. This latter is still held, however, by a bar 20 which is not removed until all-the segments have been set. When this occurs the carriers 19 are rocked by springs 28, about a shaft 21 and the type wheels strike against the ink ribbon of a platen 22. An aligning detent 23 normally held clear of the type wheel 11, engages with its tooth 26 to lock the wheel 11 during the printing operation.

[Also in Division B8] A device for applying a button to a valve of an aerosol container has means 150 for projecting the buttons pneumatically one at a time and a centring head 107 pneumatically connected to the means 150 so as to receive the projected button and guide it on to a container 117. In operation Fig. 5, a valve 116 is opened due to the presence of a container 117 (position A) arriving on a conveyer to allow air to flow from a source S through a conduit 113a. A valve 110 is thereby operated to connect conduits 108 and 121 which moves piston 111a and an attached pusher member 112 to the left, the latter moving the container from position A to B. A valve 115 is actuated by the pusher member 112 causing air to flow through conduits 124 and 125 so as to lower a piston 106b secured to a tube 134 slidably mounting the spring loaded centring head 107. After centring, the further downward movement of the tube 134 relative to the head 107 causes conduits 126, 129 to be connected via channels 127, 128 in the head 107 and a groove 134b in the tube 134. A valve 102 is thereby actuated causing air to flow through the projecting means 150 which projects a button through the tubes 153 and 134 and on to the valve stem of the aerosol container. A valve 120 is also actuated by the air flowing through the conduit 129 to cause the valve 110 to retract the pusher member 112 whereupon the conduit 124 is connected to atmosphere and the centring head 107 is raised by the air flowing through conduit 104. When the pusher 112 is next actuated the container is pushed on to a discharge conveyer (position C). Projecting means 150, Fig. 1.-When an aperture 19 of the projecting means 150 is connected to atmosphere dire to the raising of head 107, a member 6 is moved to the left by a spring 17 until a flange 10 abuts the end of a cylinder 4 and the end of a recess 12 in the member 6 abuts a screw 13. A piston 14 surrounding the member 6 is also moved back by the spring 17 to block radial apertures 9 leading to an axial aperture 8 of the member 6. In this position a button is received in an extension 20 from a guide 1. When the aperture 19 is connected to the air source S, the member 6 and piston 14 are displaced to the right until further movement of the member 6 is limited by engagement with a shoulder 18 whereupon the piston 14 is forced forward relative to the member 6 by the compressed air to uncover the radial apertures 9. The air is thereby passed through the conduit 8 to eject the button into the tube 153.

Title: An improved method of manufacturing cyanuric chloride
Filed: 1960-12-08
Abstract: Cyanuric chloride is produced by reacting chlorine with hydrocyanic acid in tetrachlorethane as reaction medium.  The chlorine should be present in stoichiometric excess.  The cyanuric chloride may be obtained by cooling and filtering, the filtrate being reused as the reaction medium.  The tetrachlorethane may be saturated with cyanuric chloride and may be obtained by concentrating the filtrate from a previous reaction.  The chlorine and hydrocyanic acid may be introduced separately into the reaction vessel in solution in the reaction medium.  The reaction proceeds at from - 20 DEG  C. to 160 DEG  C., preferably 15-160 DEG  C. Hydrochloric acid produced acts catalytically and the pressure build up of HCl may be used to effect filtration under pressure. The reaction may be carried out continuously by introducing the reactants in solution, withdrawing the reaction mixture from the vessel, filtering, degasifying the filtrate to remove HCl, separating into two parts, dissolving chlorine in one, hydrocyanic acid in the other and reusing in the reaction vessel. Specification 974,228 is referred to.
