Patent GB-525993-A (GB)
Title: Apparatus for storing and conveying card indexes or other suitable articles in containers or the like
IPC: A47B63/06
Filed: 1939-03-04
Abstract: 525,993. Storing and displaying index cards &c. BECKER, O. A. March 4, 1939, No. 7202. Addition to 503,320. [Class 146 (i)] [Also in Group XVIII] In the apparatus described in the parent Specification for storing and conveying index cards &c. in containers to an inspection or working position, the superposed containers, instead of circulating in a rectangular path, are accommodated in a vertically movable box from which the required container is removed laterally by hand or automatically after selection by a setting-device. In the arrangement described, the containers 1, Fig. 1, are supported in two boxes 3, which are moved up and down independently by screw-spindles 6 meshing with racks on the boxes. The spindles are driven from a motor 7 through gearing which can be connected with either box by a clutch operated by an electromagnet. The selection of the box and the starting of the motor are effected by the depression of one or other of two pressbutton contacts. The weight of the boxes is balanced by spiral springs acting through cords. The moving box is brought to rest by an electromagnetic brake 25 operated by the setting-device when the required container is in position. At the same time, the motor is switched off, and a magnet-operated plunger 15 pushes the selected container laterally. The container is then engaged by catches on endless chains 19 driven by a second motor 22, by which it is conveyed to -the working place. On reaching this position, a contact is made, which stops the motor 22. Depression of another press-button contact causes the container to be moved back into its box. The selecting-device comprises an endless band 43, Fig. 6, which is operated from a knob 42, and has markings indicating the containers, the marking of the required container being brought under a window. Turning of the knob 42 also adjusts two screw-spindles 38, on which travels a selector-bar 28, one end of which slides on a contact-bar .55 connected to a source of current. Two slides 29 are movable up and down by screw-spindles 35 geared to the driving- mechanism of the container-boxes. Each slide carries upper and lower insulated contact-strips 30, which are engaged by projections on the selector-bar 28. The contact-strips 30 are so connected to the motor-circuit that a containerbox will move either upwards or downwards, as necessary, to bring the required container to the working position. When a contact 31, connected to the operative slide 29, meets the selector-bar 28, the container-box is stopped. Pressure-contacts switch off the motor as soon as a box reaches the highest or lowest position. Other contacts prevent operation of the motor if a container is not pushed sufficiently far into its box.

Abstract: 725,448. Key-holders. BUXTON, Inc. March 16, 1953, No. 7207/53. Class 44. A key hanger support adapted to be fixed by rivets 28 to a key case 27 comprises an outer member 1 formed from a folded sheet metal blank and provided with a series of slots 4 having enlarged upper ends 5. Each key is carried by a hanger such as a loop 26 having an enlarged upper end 25 which can be inserted in the enlarged end 5 of a slot 4 and retained as shown in Fig. 1. An inner locking member 2, Fig. 9, is positioned inside the member 1, slots 15 providing limited endwise sliding movement on the rivets 28. An end part 17 slides in the cylindrical end part 10 of the member 1 and limits any rocking action. At the other end a spring tag 18 engages a slot 8 in the member 1 and biasses the locking member to the right so that a domed finger piece 16 projects. In this position the flat ends of teeth 14 on the locking member effectively block the slots 4 and prevent removal of key. However, the enlarged parts 5 of the slots 4 are exposed and a key hanger may be inserted, the sloping sides of the teeth 14 causing the hanger to move the locking member to the left against spring action. To remove a key, the finger piece 16 is pressed to move the locking member to the left so that the teeth 14 clear the slots 4.

Filed: 1963-02-25
Abstract: 984,988. Transistor switching circuits. KOEFOED, HAUBERG, MARSTRAND OG HELWEG A.S. TITAN. Feb. 25, 1963 [Feb. 27, 1962], No. 7457/63. Heading H3T. A circuit for remotely controlling a transistor switching device comprises a switch S, a timing capacitor C, a load L and a high voltage supply B1. The circuit is connected to the transistors by a lead IU, which performs the dual functions of feeding a control signal to the transistors and feeding power to the load from the transistor device. When used in an elevator control system, control switches and indicator loads are sited on each floor whilst transistorized bi-stable or latching circuits are situated on the top floor. Transistor T1 is normally off and T2 on, capacitor C being charged from a supply B1 of higher voltage than the supplies to the transistors. When switch S is closed, capacitor C discharges via resistor R1 and the load L until line IU approaches earth potential, when the conductive states of the transistors are reversed, energizing the load L. The rise in voltage of line IU is limited to earth potential by diode DO. The load L remains energized until the circuit is reset, e.g. by pulsing the base of T2.

Title: Improvements in or relating to the formation of adherent silver films on non-metallic surfaces
IPC: C03C17/10
Filed: 1943-05-19
Abstract: 569,388. Silvering; extracting silver. STANDARD TELEPHONES & CABLES, Ltd., NEW, A. A., and BODYCOMBE, E. L. May 19, 1943, No. 7941. [Classes 82 (i) and 82 (ii)] Finely comminuted silver is manufactured by precipitating from highly concentrated solutions of silver salts at high temperatures in the presence of high molecular weight, watersoluble organic compounds, such as gelatine or liquorice extract. The precipitation may be effected by adding ammonium formate in a water solution or in the solid form. A paste suitable for application to a surface by brushing, printing or spraying is made by separating the silver in a centrifuge, washing and mixing the separated silver with a liquid vehicle which is mutually soluble with water to the extent to which it is used. Suitable liquids are water, glycerol, ethylene glycol, methyl alcohol and ethyl alcohol. It is desirable to retain about 5 per cent of a high molecular weight organic compound content in the paste. This content is adjusted by additions to the separated and washed silver. When used in the manufacture of silvered mica condensers, or generally in the production of silver films on non-metallic surfaces, the paste is applied to the surface which is then fired at a temperature below 350‹ C. for 5-15 minutes. Electrical condensers made in this manner give consistantly good power factors of between 0.00005-0.0003 measured at 1 kc. per second.

Abstract: 115,854. Brown, R. G. April 30, 1917, [Convention date] Intermittent toothed gearing. - A gearing for converting rotary motion of one shaft F into intermittent rotary motion of a shaft 72 at right angles thereto, comprises a dish P on the shaft F with a gap in its rim co-operating with three radial arms 77 on the shaft 72. Fig. 1 is a plan of the gearing, and Figs. 6 and 10 show the disk P. The radial arms 77 lie in a plane above the level of the shaft F. When the shaft 72 is at rest, two of the radial arms 77 are in contact with the flat face of the disk. A lip 81 turned outwards from this face snaps past one of the arms 77 when it is on the rising side of the disk P. When, however, the lip 81 is descending past the second arm 77. the first arm is opposite the gap in the disk and the lip 81 forces the first arm into the gap. The uppositely-bent lip 82 engages the arm that has entered the gap and advances it until the third arm comes into contact with the flat face of the disk. The arms 77 and shaft 72 are thus turned through 120 degrees for each revolution of the shaft F.

Title: Improvements in and relating to the production of protective gases suitable for use in metal heat treatment furnaces
IPC: C01B3/04
Filed: 1936-03-18
Abstract: Nitrogen or nitrogen-hydrogen mixtures are obtained by the controlled combustion of ammonia, or partially-cracked ammonia and residual traces of ammonia are removed by passing the hot combustion gases, together with a predetermined small amount of oxygen over an ammonia-cracking or oxidizing catalyst.  The required oxygen content may be obtained <PICT:0473696/III/1> by designing the burner jet so that some air in the initial gases escapes combustion or by bye-passing some of the gases or by adding oxygen-containing gas just before the catalyst. Furthermore, in order to obtain pure nitrogen, after passage over the catalyst, the gases are arranged to possess alternately small p  hydrogen and oxygen contents and are then passed over a metallic mass, such as copper, which is alternately oxidized and reduced. In the apparatus shown, ammonia is partially cracked in the coiled tube 13 in the combustion zone 6 and is fed into the burner 10 which consists of an inner tube 21 having three concentric tubes 22, 23 and 24 forming annular passages, the ammonia passing through the middle one and air through the other two.  The hot combustion gases then pass through the catalytic zone 7, air being added through pipe 20.  The catalyst consists of a number of gauzes 14 of metals such as nickel, copper or palladium, or magnetic iron oxide may be used, and they are shielded from the flame by the perforated sheet 15.  The gases may then pass directly to a cooling zone or are passed through zone 26 filled with copper turning &c. which may be oxidized by air supplied via pipe 20A.  The hydrogen and oxygen concentrations are measured by samples withdrawn through branched pipe 27.  If the copper is oxidized the gases are given a small content of hydrogen, which is removed by the copper oxide. When this is reduced, the gases are given a small oxygen content which is again removed, so that the difficulties of accurately adjusting the combustion step to obtain pure nitrogen are obviated. The gases then pass through a cooling zone 8 carrying a water-cooling coil 18.  A refractory partition 9 is placed between the cooling zone and the remainder of the furnace.  Specification 473,697 is referred to.
