Title: Improvements in fastenings for windows, doors and the like
IPC: E05C9/04
Filed: 1924-08-18
Abstract: 220,656. Petersson, C. H. Aug. 18, 1924. Multiple-bolt fastenings; fastenings for hinged doors.-A pivoted bolt moving in a plane at rightangles to the door is operated by a a link pivoted at 'one end to a boltactuating member and at the other to an intermediate member pivoted to the bolt, and is constructed so that the pivots of the link are at right-angles to the pivots of the bolt and intermediate member. The actuating member may also move sliding bolts, to one of which the link may be pivoted. The Figures show the latter arrangement. The bolt-actuating member 17 moves vertical bolts 13, to the lower one of which one end of the link 3 is pivoted at 10. The other end of the link is pivoted at 9 to a member 2 pivoted at 7 inside a recess 18 in the bolt 1 which is pivoted at 5 to the door. The pivots 9 and 10 are at right-angles to the pivots 5 and 7. Movement of the actuating member 17 moves the bolts 13, and consequently the bolt 1, into locking or unlocking position. When only the bolt 1 is employed, the link 3 is pivoted directly to the member 17.

Title: Improvements in and relating to land mines
IPC: C07C29/62
Filed: 1960-06-02
Abstract: 918,173. Land mines. RHEINMETALL G.m.b.H. June 2, 1960 [June 4, 1959], No. 19628/60. Class 9 (2). A land mine comprises upper and lower parts 1, 2 made of a weather resistant stable explosive or a thermoplastic composition, the part 1, which houses the fuze mechanism, being slidable in a recess in the part 2 and supported by a flexible tube 6 containing air under pressure. The uppermost section of the part 1 is frustoconical and surrounded by an annulus 4 of similar explosive, which holds the parts together and may be secured in position by adhesive tape. Below a certain load on the mine, the air cushion returns the part 1 to its initial position should it be depressed. Should this load be exceeded, a valve 7 opens and air escapes from the tube 6, whereupon the part 1 moves into contact with the part 2 and a bush 10 holding a detonator 16 is forced upwards after a flange 17 engaged in the fuze body 9 has sheared. The upward movement compresses a spring 12 supporting a striker member 11 holding a percussion cap 14. Flexible arms 23 of a distance sleeve 13 supporting a firing pin 15 are forced outwardly by inclined surfaces 24 of the bush 10 and the cap 14 is forced against the pin 15 as claimed in Specification 918,174. A telescoping handle for transporting the mine is provided. The fuze parts and handle are preferably of synthetic plastic.

Patent GB-516681-A (GB)
Title: Acetylene generator
IPC: C10H5/00
Filed: 1938-07-04
Abstract: 516,681. Acetylene generator. I. G. FARBENINDUSTRIE AKT.-GES. July 4, 1938, No. 19757. Convention date, July 2, 1937. [Class 2 (i)] In an acetylene generator having apparatus for stirring the carbide and the calcium hydroxide in order to obtain substantially dry hydroxide, the supply of water and the motion of the device for stirring the carbide are automatically regulated in dependence on the pressure or volume or both of the acetylene in the generator or in a storage vessel. In the Figure, in a generator 1 is mounted a stirrer drivenby a motor 2 the circuit of which includes a deferred-action switch 3 which is connected by a cord 4 with the bell 5 of a gasholder 6. The water enters the generator by way of a valve 8 which is also connected with the bell 5 by means of a cord 9. When the bell 5 is below a certain position the generator is permenently running, but when it rises above this position, the valve 8 is closed and the switch 3 is set for deferred-action. The operation'of the apparatus is as follows : When the bell sinks to the operating position the switch 3 switches on the motor 2 driving the stirrer and after a short time the water valve is opened and acetylene generated. So long as the quantities of gas produced and drawn off are substantially equal, the working remains unaltered. If, however, the bell rises above the operating position the valve 8 is closed by the cord 9 and simultaneously or subsequently the deferred-action switch 3 is set for operation but keeps the stirring apparatus in motion for a predetermined period, for instance one hour, after the cessation of water supply.. If during this period the bell once more sinks below the operating position, the switch is returned to the position in which it is no longer set for deferred-action and the valve is opened again. The automatic switching may be carried out mechanically, electrically or optically. The addition of water and the deferred-action switch may. alternatively be regulated by the'pressure of acetylene in the holder through a manometer, the cords 4 and 9 or an arrangement of electrical contacts in the manometer being suitably adapted. The invention may be applied to any form of dry generator, the stirring apparatus being suitably adapted.
Patent GB-198134-A (GB)
Abstract: 198,134. Drummond, A. March 23, 1922. Systems, electric.-In order that a current of sufficient strength at starting may be obtained, a magneto is driven at higher than engine speed, so that it makes more than two cycles for each ignition, the impulses not required for ignition being short-circuited. For this purpose a disc c, which may be a gear-wheel on the half-time shaft, is provided with a conducting-contact, insulating segment, or space c<1> which engages or passes close to a brush E connected either to the hightension or low-tension circuit. When a conducting contact is used the current passes through it into a second contact connected to one of the sparking-plugs. If an insulating segment is fitted into the gear-wheel, or a space is left, the sparking-plug is not short-circuited while the brush is adjacent to the segment or space.

Filed: 1962-05-23
Abstract: 932,785. Attaching pronged fasteners. MORLEY CO. May 23, 1962 [June 13, 1961], No. 19827/62. Class 89 (3). [Also in Group XXV] A machine for attaching handles 42, having pre-attached pronged fasteners 44, to a strip of material 16, such as the side of a mattress, comprises a frame 10, having a bed 14, a reciprocatory head 20 provided with driving dies 22, means 65, including fastener closing dies 60, for positioning the fasteners, and feed means 40 for feeding the handles between the driving and closing dies. The head 20 is guided in the frame 10 and driven via a toggle linkage 24 by means of a ram 32 supported on a bracket 34. The closing dies 60 are provided in discs 65 which are rotated on the upward stroke of the head by means of a ratchet-gear device driven by a ram 70; locking rings 62, Fig. II, are fed into each empty die via tubes 67. The feed means 40 for the handles is in the form of a guideway into which handles are inserted and fall by gravity to a position under the dies 22 where they are supported on the tapered edges of spring-loaded levers 52. In operation, upon actuation of a valve 86 in one direction, compressed air is fed to the ram 32 so as to drive the head downwardly and thereby force the prongs through the strip 16 and into contact with the closing die, the prongs then being folded over the locking ring 62; during this operation, the ram 70 is operated in sucn a direction as not to rotate the discs 65. Upon actuation of the valve in another direction, compressed air is fed to the opposite ends of the rams 32, 70 thereby, respectively, returning the head 20 and indexing both discs around so that locking rings are located under the dies 22 in readiness for the next operation. Air jets 88 are provided which, in addition to the gravitational force, move the handles under the dies. Air jets are also provided for ejecting from the closing dies 60 any damaged locking rings.

Title: Detecting malignant cells
IPC: G01N33/60
Filed: 1973-04-26
Abstract: 1432834 Detection of malignant cells; detection of cancer cells AMERICAN SCIENCE & ENG Inc 26 April 1973 [26 April 1972] 19911/73 Headings G1A and G1B Malignant cells are detected by a method comprising gathering a sample of exfoliated cells that may include malignant cells, placing the sample in a solution containing a gallium compound and allowing the gallium to be absorbed from the solution by the cells, washing from the cells gallium not absorbed by the cells and detecting the gallium in the cells. The test may be carried out with the cells either as a smear on a slide or in suspension in a continuous flow system. The gallium compound may contain radio-active gallium. Alternatively, a non-radio-active form of gallium may be used and after its absorption by the cells the gallium compound may be reacted with 8- hydroxyquinoline, optionally in the form of 8-hydroxyquinoline 5-sulphonic acid tagged with S35, the fluorescence and if appropriate the radioactivity of the sample being measured. There is reference to use of a C14 labelled compound. For a slide test using cells treated with non-radio-active gallium then with 8-hydroxyquinoline, the slide is exposed to light of 3650A or 4358A wavelength and the fluorescence so produced is measured. For a flow test using cells treated with non-radioactive gallium then with 8-hydroxyquinoline- 5-sulphonic acid tagged with S35, both the radioactivity and the fluorescence produced by U.V. light are determined for each cell, the results being gated together to ensure that each radio-activity count is associated with a single cell. In the determination of the fluorescence of a sample exposed to 8-hydroxyquinoline Fig. 2 (not shown) the light scattered from the cell is removed using a long wavelength pass filter (25). The 4358A incident wavelength is preferred to reduce possible fluorescence from organic cell constituents. A broadband filter may be used to exclude scattered excitation light from the detector (26) without reducing the fluorescence intensity appreciably. The radiation source may be a mercury lamp providing 42 to 76 w. in the 4300 to 4400A range, or a laser providing 100 mw. of 3638A light which can be focused on the desired area of illumination.

Abstract: 793,186. Amplifiers; non-contact-making relays. ELECTRICITE DE FRANCE. July 9, 1954 [July 10, 1953; Aug. 7, 1953], No. 20220/54. Class 40 (4). [Also in Group XL (c)] An amplifier comprises a frequency discriminator D, Fig. 1, of the Foster-Seeley type which is supplied with a fixed frequency at P. The discriminator includes a variable tuning condenser C which is mechanically coupled to a galvanometer movement G so that the voltage Us of the direct current output is an approximately linear function of the input Ue to the galvanometer. The fixed frequency is supplied by a quartz-controlled oscillator OS, a clipper E and an amplifier A with negative feedback and has a substantially constant amplitude. In a modification, Fig. 5, the usual spring restoring force on the galvanometer is not used and the torque produced by the input Ue in coil G is balanced against the torque produced by a feedback from the discriminator output Us in a second coil GA, the relation between Ue and Us being determined by the electrical constants of the circuit. A number of discriminators may be fed by the same oscillator, clipper and amplifier. A different form of frequency discriminator is used to provide more power. A wide-band transformer 19, Fig. 6, is fed with a fixed reference frequency from the output valve 11 of the amplifier. Transformer 21 is fed with the same frequency from valve 11 but with phase controlled by inductively coupled tuned circuits 15, 16. The circuit 16 includes a condenser C controlled by the input voltage Ue and by the output voltage across the load 40, the resultant torques being balanced as in the previous example. The circuit 16 is coupled to transformer 21 by a pentode 20. The combined output of transformers 19, 21 is rectified by a double rectifier bridge. The output current is independent of the load. The load current Is and the voltage across the load 40 are proportional to the signal Ue. The tuned circuit 28 serves as a high-frequency choke. The amplifier comprises three pentodes 9 having a tuned anode circuit, 10 being a cathode follower and 11 providing the output. The oscillator and clipper are combined in OS.
