Abstract: 921,840. Suspension filing systems; gramophone-record envelopes; index tabs. G. ZIPPEL, [trading as HERBERT ZIPPEL, KOM.-GES.]. Dec. 29, 1960 [Jan. 5, 1960; July 13, 1960 (2)], No. 44557/60. Classes 16, 146 (1) and 146 (2). A suspension filing device for suspending gramophone record envelopes, folders, or the like from a single supporting rail is provided with a recess open at the top, which is shaped to form one or two noses to engage the supporting rail, and one or two tongues extending horizontally, which in use, pass through apertures in the envelope or folder adjacent its upper edge, whereby the upper edge of the envelope or folder is supported on the upper edge or edges of the tongue or tongues. The filing device 1 is recessed at 3 to provide two opposed noses and has a single tongue 16 provided with a sheet metal extension 18 at its lower edge, which, in use, is inserted through a slit or circular aperture in one cover of a folder or envelope to lie between the covers thereof and the extension 18 pushed through a second slit and bent back on itself to secure the filing device in position. Alternatively, the device is provided with two tongues 4, 4<SP>1</SP> extending in the same or opposite directions, at least one of which is flexible to facilitate engagement with slits 11, 11<SP>1</SP> adjacent the upper edge of a folder or envelope. The tongue 4<SP>1</SP> may be bent back on itself adjacent the plate 1 to extend in a direction parallel to the tongue 4 and a small tongue provided at said bend extending in the opposite direction to the tongues 4, 4<SP>1</SP>, Fig. 22 (not shown). The tongues have recesses 42 at their upper or lower edges, Fig. 14, to prevent tearing of the apertures. The thickness of the plate 1 is reduced at the lower edge 6 and the tongues cranked along lines 40, 40<SP>1</SP> to accommodate the portion of the folder or envelope between the slits 11, 11<SP>1</SP>. Similarly the plate may be reduced in thickness where it joins the tongue 16, Fig. 5.

The gramophone-record envelope is open along the edge 22 and a record maintained therein by a press-stud fastener joining the two covers at the lower corner thereof or by cutting the envelope at 29 whereby the lower edge 24 of the record projects therethrough. The envelope may be closed on all four sides and one cover slitted along a line parallel to and spaced from one side edge. Alternatively the envelope is shaped so that the lower edge is inclined downwards from the open side, or the lower edge inclined by arranging the tongues 4, 4<SP>1</SP> at an angle to the opposed supporting noses 46. Index tabs.-The upper plate-like portion of the filing device 1 may be provided on one side with a transparent pocket accommodating an index card. Specification 751,152 is referred to.
Patent GB-900584-A (GB)
Title: Luminescent screens
IPC: H01J9/22
Filed: 1958-04-02
Abstract: A luminescent screen, for excitation by cathode rays or U.V light, comprises a thin transparent crystalline film of activated zinc phosphate on a smooth surface of a refractory non-oxidizing base. The base may be transparent and formed of glass, or may be opaque and formed of platinum or a metal oxide ceramic such as Al2O3.  The screen can be made by the method and apparatus described in Specification 900,582 by vaporizing within a high vacuum zinc phosphate and an activator material and depositing a thin film of the vapours on a glass base, and subjecting the film and base to baking in the presence of oxygen, e.g. air, at a temperature between 500 DEG C. and 800 DEG  C., preferably between 550 DEG  C. and 600 DEG  C., for a period of between about 15 minutes and an hour.  With manganese as activator the colour of luminescence moves from green to red in a range of concentrations of the activator of from about 1 to 10% mols., red commencing at about 5% mols.  The zinc phosphate can be replaced by the components thereof, e.g. zinc or zinc oxide and phosphorus which are vaporized from separate vessels.  Commercial activated zinc phosphate can be used as the starting material and coactivators can also be used.  A transparent luminescent screen formed as above can be used in cathode-ray tubes for daylight viewing of the image, the inner surface of the wall of the tube being covered with a light-absorbing coating, e.g. of "Aquadag" (Registered Trade Mark).

Abstract: 1,000,928. Power-distribution tracks. LIGHTOLIER Inc. Nov. 15, 1963 [Aug. 12, 1963], No. 45150/63. Heading H2E. The Specification relates to mounting flush with a ceiling or wall, power-distribution tracks of the type described and claimed in Specification 1,000,930. As shown, the distribution track comprises a channel-shaped member 11 in which conductors 28, 29 are carried in an insulating strip 18 which is claimed in Specification 1,000,923. The channel member 11 is supported within an inverted U-shaped housing 30 which is set into the mounting surface, the open face of the track being flush with the mouth of the housing. The track is held in the housing by torsion springs 45 and channel-shaped members 50. The coil of each spring is positioned beneath a member 50 which themselves engage under flanges 15 to hold up the track. The ends of the torsion springs project through a hole in the housing and spring apart. In a further embodiment (Fig. 5, not shown) channels engage under the flanges 15 of the track and are suspended from the housing by bolts. The housing is mounted in the ceiling or wall by means of plates 40 formed on the end of lathing strips 41, the plates 40 being inserted into grooves 36, 39 formed on the side walls of the housing. To connect adjacent housings together strips 71, 71<SP>1</SP> are fitted into grooves 36, 39 (Figs. 2, 3, not shown). In the embodiment of Fig. 8 (not shown) the housing is installed in a dry type ceiling in which the edges of adjacent tiles 82 are positioned between flanges 38, 33 and 38, 34.

Title: Improvements in or relating to channel switches for channel selection and channel tuning
IPC: H03J5/12
Filed: 1962-11-29
Abstract: 1,018,761. Keyboard switches. W. PREH and A. PREH, [trading as PREH ELEKTROFEINMECHANISCHE WERKE, JAKOB PREH NACHFOLGER]. Nov. 29, 1962 [Dec. 2, 1961; Sept. 18, 1962], No. 45249/62. Heading H2B. [Also in Division H3] In a channel selector and tuner, having mutually cancelling keys provided with push-buttons, the linkage by means of which the movement of a push-button is transmitted is constructed as a screw-threaded spindle which coacts with a travelling nut displaceable along the spindle and connected to a tuning member, and a coupling between the push-button and the spindle is provided which permits transmission of a torque from the push-button to the spindle only when the key is depressed and the spindle is retained in the operative position. As shown in the Figs. 2 and 1 (not shown), a plurality of push-buttons 1 are each provided with an associated linkage for transmitting its movement, comprising a screw-threaded spindle 2 having a thickened end portion 3 and a reduced end portion 4 mounted in apertures in walls 5, 6 of the switch frame. When the push-button is operated in the position a of Fig. 1 the spindle is moved to the right by the push-button 1 acting against abutment 13 on the end 3 and slide 10 biased by hairspring 9 and clamped to spindle 10 moves over spring-loaded latching member 12 until the latter engages behind boss 10a. The spindle is thus held in its operative position so that when the push-button 1 is released the latter is biased to the right by coil spring 15 until the external teeth of an abutment 14 on the end 3 engage in corresponding recesses in the base of the hollow push-button 1 and a collar 16 on the pushbutton comes into contact with fixed abutment 17, Fig. 1c. When the push-button is now rotated, spindle 2 rotates and travelling nut 11 connected to an associated tuning member moves along the spindle. The spindle end 3 is fitted into the push-button at 19 so that the flow of air into and out of the interior of the button is throttled so that if the push-button is released when in the position Fig. 1b the push-button due to the slow flow of air into the push-button encounters the abutment 17 with some damping. Similar damping is encountered during the mutual cancelling of the keys when the backward movement of the spindle is damped.

Title: Switching circuits especially for shunt-wound motors
IPC: H02P7/00
Filed: 1971-09-28
Abstract: 1361184 Converting, control of D.C. motors MOLINS Ltd 28 Sept 1971 [29 Sept 1970] 46301/70 Headings H2F and H2J [Also in Division H3] A switching circuit for applying a reversible direct voltage to an inductive load, e.g. the field windings of shunt motor, from an A.C. supply comprises: a rectifier circuit 10; a bridge of four controlled switches, SCR's 12A, 12B through which the direct voltage is applied to the load in either direction; and means, e.g. triac 14, in the A.C. part of the circuit for limiting the rise in current when the direction of current through the load is reversed. If initially SCR's 12A are conductive and it is desired to change the direction of the voltage by firing SCR's 12B, then triac 14 is extinguished long enough for the currents through SCR's 12A to decay sufficiently for them to become extinguished. Pulses are then applied to the coils B to refire triac 14, and fire SCR's 12B. In an alternative arrangement the trial is replaced by a filament lamp. When it is desired to change the direction of the voltage SCR's 12B are fired and the lamp limits the supply current during the time that all four SCR's are on, until the current decays through SCR's 12A sufficiently for them to extinguish.

Abstract: 1,125,829. Animal feeding appliances. S.A.B.E. SPECIALITES ALIMENTAIRES POUR LE BETAIL. 17 Oct., 1966 [18 Oct., 1965; 25 Feb., 1966; 18 July, 1966; 1 Sept., 1966], No. 46310/66. Heading A1M. [Also in Division B1] Animal feeding apparatus comprises a container 1 connected to at least one feeding teat 4 and receiving powdered food from a hopper 6 via a conveyer 9 and liquid from a supply, the container being provided with means 28 for mixing together the powdered food and liquid and the hopper having a notch 6a formed in the lower part of the side wall and controlled by an adjustable slide 10 so that the thickness of the layer of powdered food withdrawn from hopper 6 by the conveyer 9 can be varied. The conveyer 9 is an endless belt conveyer and is moved by a pawl and ratchet device 13-15 operated by cam means 23 driven by an electric motor 26, the oscillatory movement of arm 16 carrying pawl 15 being controlled by an adjustable stop 18. The mixing means 28 is operated by a further electric motor 31 which also drives a stirrer 30 located in an intermediate hopper 11. The motors 31 and 26 are actuated by switch means 35 adapted to close when the feed in container 1 falls below a predetermined amount and open when the amount of feed reaches a predetermined higher level. The switch 35 also controls an electromagnet - or solenoidoperated valve 34 controlling the supply of water to container 1 from the supply tank. A time lag device operates on motor 31 so that all the powdered feed delivered by conveyer 9 is properly mixed. Heating means 46, 47 may be provided and hopper 6 vibrated by electromagnetic means 12. In a modification the time of operation of conveyer 9, the stirring means and the opening of valve 34 are controlled by a programmed device. In a further modification the amount of powdered feed supplied by the conveyer 9 is dependent on the weight of the animal feeding, the animal standing on the scale pan of a weighing device coupled to the adjustable shutter 10. In this embodiment the feed is premixed in an intermediate container connected by a siphon device to container 1. The hopper 6 is also supplied with powdered feed from a bulk supply by means of an auger. In a further modification the powder moved by conveyer 9 falls on to an inclined apron which directs it into container 1, a perforated duct connected to a warm water supply extending across the top of the apron so that powder and water are mixed before reaching container 1. A vibrating conveyer may replace belt conveyer 9.
