IPC: B29D99/00
Filed: 1929-08-17
Abstract: 317,728. Kalle & Co. Akt.-Ges. Aug. 20, 1928, [Convention date]. Capsules, non-metallic.-Capsules and other water-swollen bodies made of cellulose esters and in particular of acetone-soluble cellulose acetate are prevented from shrinking at low temperatures by using as dispersian medium a salt solution instead of water. When the capsules are frozen and then thawed they retain their original dimensions and capacity to shrink on drying. Before drawing the capsules on the containers, which are to be sealed, they are immersed in pure water to remove the salt water and restore them to their original water-swollen state. As salt solutions there may be used solutions of common salt, or other suitable salts such as sodium acetate. In an example, water moist capsules of cellulose acetate are immersed in a 10 per cent solution of sodium chloride and then taken out and packed in the usual waterproof manner. The Specification as open to inspection under Sect. 91 (3) (a) relates also to the treatment of cellulose hydrate and specifies also magnesium sulphate and calcium chloride as suitable salts. This subject-matter does not appear in the Specification as accepted. Reference has been directed by the Comptroller to Specifications 224,487, 236,336, and 259,568.

Title: Improvements in and relating to electric translating circuits utilising electric discharge devices
IPC: H02M7/00
Filed: 1933-09-14
Abstract: 422,073. Converting. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London.-(Assignees of Mittag, A. H. ; 1455, Dean Street, Schenectady, New York, U.S.A.) Sept. 14, 1933, No. 25501. Convention date, Sept. 14, 1932. [Class 38 (ii)] To ensure parallel operation of discharge devices in a converting arrangement having groups of parallel connected grid controlled discharge devices 15, 16, 17 and 18, 19, 20, inductances 21 are inserted in the cathode leads of the devices and the grids of each group connected to one side of a secondary winding of a grid transformer 28, the other side being connected to the cathodes through resistances 27. When a discharge device (e.g. discharge device 15) commences to conduct before the others in the group, the voltage drop in the inductance 21 is impressed across the seriesparallel connection of resistances 27, thus applying a negative bias to the grid of discharge device 15 and a positive bias to the grids of discharge devices 16, 17. The two secondaries shown may be replaced by a single centre tapped winding. With this arrangement the de-ionizing current of the discharge devices may flow directly from the secondary winding through the grid-cathode circuits of the two groups of discharge devices and the inductive windings 21. The Specification as open to inspection under Sect. 91 comprises also a modification, Fig. 1 (Cancelled), in which the centre tapped secondary of the grid transformer 28 is connected to the grids through resistances 27, the centre tapping being connected to the lead interconnecting the inductances 21. In a modification of this, to enable a multiple anode discharge device with a single cathode to be used, the inductances are arranged in the anode leads and inductively coupled to the grid circuits. Modifications of the inductance arrangement are described. This subjectmatter does not appear in the Specification as accepted.

[Class 40 (iv)] Substation amplifying and loud-speaking equipment utilizes the ordinary telephone receiver for both reception and transmission by means of a coupling unit comprising a microphone for receiving incoming speech and an electromagnetic or inductive coupling device for outgoing speech. As shown in the Figure, the unit comprises a casing 10 having a perforated cover-plate 12 against which the telephone receiver 15 is supported on a flange 14. The electromagnetic coupling device for outgoing signals comprises a permanent magnet 18 having coils 17 connected to the output of amplifier 63 deriving its input from microphone 62, the magnet 18 being shaped to lie around an inner casing 56 enclosing a microphone 55, preferably of crystal type, which responds to incoming speech and is connected to amplifier 60 and loud-speaker 61. The front wall of casing 56 is formed by a diaphragm connected to the crystal. Switch contacts 58, normally short-circuiting the microphone 55 or amplifier 60, are opened when the receiver 15 is placed in position. Each amplifier is disabled by output in the other. In a modification, Fig. 2 (not shown), the electromagnetic coupling device for outgoing signals is replaced by a coil which may have an iron core and is inductively coupled to the windings of the telephone receiver. The receiver diaphragm does not respond to outgoing signals in this case. The speech coils 17 may also be closely coupled to the receiver windings. Automatic volume control may be provided, and a single amplifier may be used for both directions by means of manual or automatic switching arrangements controlling the output and input connections as described in Specification 492,368. Additional loud-speakers and microphones may be located in different rooms and selectively connected up by a switch.
