Abstract: 591,527. Lamp supports. CROMPTON PARKINSON, Ltd., RANDALL, A. L., TEMPLETON, F. J., and SEABORNE, F. May 11, 1945, No. 11898. [Class 75 (iii)] [Also in Group XXXV] An inductance used as a choke in the supply to a discharge lamp has a body part which forms part of the suspension system for that lamp and a top cover which may be spaced apart from the body part without complete detachment. The choke coil 2 is mounted in a core 1 to the faces of which flanges or casings 3 are fixed by the bolts which hold the core laminations together. In the upper casing are terminal blocks 4, 5 and in the lower casing terminal block 11. Tappings from the choke are connected to block 5, and one connection from the supply line to the leads 12 to the lamp 26 is made through conductor 6, coil 2, block 5, movable lead 8, block 4, conductor 9, block 11, and the other connection through conductor 7, block 4, lead 10, block 11. Top and bottom covers 13, 24 are provided for the casings 3 and after removal of nut 20, by sliding studs 16 on upper casing 3 in slots 10 in lugs 14 fixed to cover 13, this top cover may be completely removed from the choke structure or opened only sufficiently to allow access to terminal blocks 4, 5. In a similar manner the bottom cover 24 can be removed or opened for access to terminal block 11. The pin and slot connection may be replaced by hinged links.

Title: Process for the Recovery of Volatile Solvents used in Manufacture.
Inventor: BREGEAT JEAN HENRY
IPC: B01D53/00
Filed: 1917-08-21
Abstract: 128,640. BrÚgeat, J. H. May 25, 1917, [Convention date]. Volatile liquids, recovering.- Certain volatile solvents used in manufacture are recovered from gaseous mixtures containing them, by absorption in phenolic reagents, such as crude carbolic acid or crude cresols, and subsequent distillation and condensation. The solvents in question are methyl alcohol, amyl alcohol, ethyl acetate, amyl acetate, carbon tetrachloride, chloroform, di-, tri-, or tetra - chlorethylene, tetra- and pentachlorethane, and petrol. Using the apparatus shown, the vapours are washed by a counter-current of cresols in the absorption column 2, and the cresol charged with the volatile bodies is pumped to the tank 6 and then flows through a heat-exchanger 7 to a steam heater 8 and cascade evaporator 9 heated by steam from a pipe 21; the volatile bodies pass off with the steam to a distilling-column 10, where they are rectified, and thence to condensers 11, 12. The cresols deprived of the volatile bodies flow from the evaporator 9 to the heat-exchanger 7, and thence to the cooler 14, and so back to the storage tank 1 for re-use. Specification 127,309 is referred to.

Title: Mechanism for Selectively Positioning an Output Member Along a Predetermined Axis of Movement
IPC: F16H35/00
Filed: 1968-03-12
Abstract: 1,169,321. Photographic type-composing. NATIONAL CASH REGISTER CO. 12 March, 1968 [31 March, 1967], No. 12010/68. Heading B6W. [Also in Division F2] An output member 33 is moved axially predetermined incremental amounts by selective operation of plungers 48, 58 acting on cam members 41, 42 and 43. The cam 42 has surfaces 63, 64 inclined at 45 degrees to the axis of movement of output member 33 and engaging similarly inclined surfaces on cams 41, 43. Inclined surfaces 65, 66 on plunger 58 engage cams 41, 43 respectively. The plungers are mounted in adjusting screws 56 and are actuacted by solenoids 52, 53, 62. Operation of solenoid 53 causes downward movement of cam 41 and one unit of axial movement of output member 33. Operation of solenoid 52 causes upward movement of cam 43, twice the extent of the movement of cam 41, and two units of axial movement of output member 33. Operation of solenoid 63 causes axial movement of plunger 58 and cams 41, 42 and 43 and four units of axial movement of output member 33. Various combinations of these movements produce resultant axial movements of up to seven units. Four such mechanisms are located at rightangles to each other to control the position in its own plane of a character-carrying mask 26 in a photographic type-composing machine including a laser beam source 20, Fig. 1, a shutter 21, a focusing and reducing lens 22, a second reducing lens 24, and the recording film 25.

Rotation is continued, with periodic reversal of direction, until the hardening of the resin is complete. If desired, the surface 48 may be coated with a thin layer of epoxy resin before positioning the band thereon. The band may be formed by a number of wire bands arranged side by side or by wire wound or with the turns abutting.

Title: Improvements in or relating to electric bistable devices

Filed: 1963-03-29
Abstract: 1,037,407. Transistor bi-stable circuits. TELEMECANIQUE ELECTRIQUE. March 29, 1963 [April 26, 1962], No. 12628/63. Heading H3T. In a bi-stable circuit comprising, for example, a reciprocally-coupled pair of transistors, means comprising a memory device which memorizes the instantaneous state of the bi-stable circuit is provided for ensuring that when the circuit is switched off and then switched on again the circuit assumes the same state as it had immediately prior to being switched off. In the circuit shown comprising reciprocallycoupled transistors T 1 , T 2 , a delay circuit comprising resistors R b , R c  and capacitor C is connected in one cross-coupling whereby, apart from the memory device constituted by a winding E on a core M of square-loop material and connected in the other cross-coupling, transistor T 1  would always become conductive in preference to transistor T 2  on switching on. If, immediately prior to switching off, transistor T 1  is conducting then the base current of that transistor flowing in a direction represented by arrow 1 switches the core M to a state such that winding E presents little impedance to the flow of current through resistors R a1 , R d  and R 2  when the circuit is once again switched on and as a consequence, due to delay circuit R b , R c , C, transistor T 1  becomes conducting and transistor T 2  remains switched off. If, however, transistor T 2  is conducting immediately prior to switching off, core M is switched to the opposite state by current flowing in the direction represented by arrow 2 through transistor T 2  and diode D 2 . Then on switching on once again, current commences flowing in direction 1 through resistors R a1 , R d , R 2  and core E but its build up is delayed due to its having to switch core M, so that transistor T 2  conducts before transistor T 1  and the circuit is re-established in the state it had immediately prior to switching off. Diode D 1  is provided in order to balance the circuit.
