Patent GB-1316233-A (GB)
Title: Fuse holding apparatus
IPC: H01H85/54
Filed: 1971-04-19
Abstract: 1316233 Fusible cut-outs LITTELFUSE Inc 19 April 1971 [24 Aug 1970] 27153/71 Heading H2G A fuse holder for mounting in a hole in a panel comprises a main body 6 which can be fixed in a panel 2, and a removable fuseholding unit comprising the parts 14 and 25 which retain one end of a fuse 16, the part 25 acting as an electrical terminal member. The fuse-holding unit is inserted in the main body and locked into position by pressing on the vertical surface 12a of the front face of the unit against the action of a spring 80 until a resilient projection 33 on member 25 engages the inner surface of a hole 65 in a contact member 64, the clip being held in the hole by the action of the spring which also connects the corresponding fuse terminal to a contact member 71. With the fuse-holding unit locked in this position the arrangement is such that the front of the unit lies adjacent to the frame portion 10a of the main body, this arrangement being said to not present any convenient shoulder for grasping and pulling the fuse-holding unit from the main body. The fuse-holding unit is removed from the body by depressing an angled portion 12b of the front surface of the unit, which action disengages the projection 33 from the hole 65, permitting outward movement of the fuseholding unit under the action of the spring (Fig. 5, not shown). The main body of the holder may be formed from two generally U-shaped members 44, 44<SP>1</SP>, having grooves into which the contact members 64, 71 are inserted, the construction being held together by a frame member 10, having two resilient projections 97, 97<SP>1</SP> which clip into outer U-shaped channels 46a, 46a<SP>1</SP> in the members 44, 44<SP>1</SP>. Angled portions of these projections may also act as a means for holding the fuse-holder in a hole in a panel (Fig. 2, not shown). The claims also relate to an arrangement of such fuse holders in a panel wherein the front portions of the fuse-holding units and frame members are colour coded for identification purposes (Fig. 1, not shown).

Title: Cold cathode sequence gas discharge tube circuits
Inventor: HURR ERNEST ROY
IPC: G01D5/18
Filed: 1959-08-10
Abstract: 899,465. Electric selective signalling systems. BUSH & RANK CINTEL Ltd. Aug. 18, 1960 [Aug. 10, 1959], No. 27294/59. Class 40 (1). In a cold-cathode sequence gas discharge tube circuit for measuring the relative displacement between two members, the discharge tube is of the type having two guide electrodes between each pair of adjacent cathodes, and means are operable whenever a read-out is required to ensure that the discharge takes place from a cathode of the tube and not one of the guide electrodes. In the circuit described, movement between the two members is detected by means of a scale 5 having transparent and opaque portions 3, 4, and photo-cells 1, 2 so placed as to produce square waveforms which differ in phase by 90 degrees, the sense of the phase difference being determined by the direction of motion of scale 5. The outputs from photocells 1, 2 are supplied to respective trigger circuits 11, 12 and 13, 14 of which valves 11, 13 are normally conducting. The output of each trigger is supplied to one of the guide electrodes 25, 26 to step the discharge from one cathode to the next in one direction or the other. When a read-out is required, contacts 31, 32 are closed so that valves 11, 13 conduct and valves 12, 14 are cut off, thereby driving both guide electrodes 25, 26 positive and forcing the discharge to take place from the nearest cathode. To prevent counting errors when contacts 31, 32 are reopened, caused by the discharge moving on to the wrong guide electrode, a storage device is preferably included, sensitive to the currents flowing in the guide electrode circuits. This storage device may then, through a diode gate, be arranged to connect a capacitor to the grid of that valve 11 or 13 which was not associated with the discharge before the read-out was taken so that the potential of that grid falls more slowly, thereby ensuring that the discharge is transferred back to the correct guide electrode.

Title: Improvements in the manufacture of films, foils, ribbons and like products
IPC: B29C48/08
Filed: 1935-10-03
Abstract: <PICT:0463567/IV/1> A shaped film-forming composition is drawn into contact with and supported on a surface which is travelling in a gaseous medium, and a pocket of liquid which is compatible with the base of the products, is maintained in the angle between the shaped composition and the supporting surface so as to prevent air from being drawn into said angle.  Suitable liquids for this purpose are solvents and plasticizers for the film-forming base, particularly a solution of a liquid plasticizer in a volatile solvent identical with that of the film-forming solution.  There may be added to the liquids, colouring agents or effect materials which it is desired to introduce into the film.  In an example, a solution of cellulose acetate in acetone is supplied from a casting box 10 on to a metallic band 18 passing around a drum 19 driven in the direction of the arrow.  A pad of soft leather 20 resting on the band 18 is supplied with a solution of diethyl phthalate in acetone.  Film formation may be carried out at speeds of 50--100 feet per minute without bubble formation.  Films may be formed in a single operation or may be built up by the successive deposition of two or more layers, each layer except the last providing a supporting surface for the next layer, and a pocket of air-excluding liquid being maintained in the angle between it and the shaped composition forming the next layer.  The films may have a basis of cellulose derivatives, polymerized vinyl acetate or polymerized unsaturated hydrocarbons.

Title: Improvements in or relating to locking devices for doors and the like
IPC: E05C9/04
Filed: 1931-10-02
Abstract: 385,046. Door fastenings. TIBBLES, H. J., Brodsworth, Blenheim Crescent, Leigh-on-Sea, and RELY-A-BELL BURGLAR & FIRE ALARM CO., Ltd., 49A, Wilson Street, Finsbury Square, London. Oct. 2, 1931, No. 27402. [Class 44.] In a fastening of the kind employing a locking bar engaging a staple and secured by a padlock, the staple is rotatable and controls bolt fastenings. As shown in Figs. 1 and 2. the rotatable staple 1 is carried by a spindle 2 having a pinion 5 meshing with racks 6, 7 on bolts 8, 9, the arrangement being such that the bolts are shot by rotating the staple into registration with a slot in the locking bar 10. The staple may be locked against rotation by a bolt 20 engaging pinion 5 and controlled by a revolving barrel lock 15. As shown, a lug 16 rotating with the barrel co-operates with a cam aperture 17 in a slidable plate 18 which carries the bolt 20 and is urged to locking position by a spring 21. The locking bar shown is in two parts hinged together at 25, one part engaging the staple and secured by padlock, the other having pin and keyhole slot connection 26 with the door, and engaging a socket 11, the locking bar being placed to cover the lock 15. A form is described in which the staple registers with the slot in the locking bar when the bolts are retracted, the bar being first engaged with the staple, which is then rotated to shoot the bolts and prevent withdrawal from the slot. In this case the locking bar is arranged not to cover lock 15. In conjunction with the above arrangements the locking bar may be rotatably mounted and adapted to operate bolts, this arrangement being particularly suitable for double doors, the locking bar controlling the bolts on one door and the staple controlling the bolts on the other. Arrangement may be made for operation of the bolts otherwise than by the staple when desired. According to the Provisional Specification the bolts may be operated by follower arms on the staple spindle and the bolts locked by lever tumblers of ordinary type.
