Title: Improvements in and relating to animal traps
IPC: A01M23/24
Filed: 1924-09-04
Abstract: 233,219. Douglas, V. R. G. May 12, 1924, [Convention date]. Animal traps. - A spring-jaw trap comprises a base 1, two jaws 3 pivoted thereto and operated to close by a spring 4, and a treadplate 6 directly engaging a projection 7 on one of the -jaws to hold the trap set. The gripping edge of one jaw is serrated and that of the other is plain as shown in Fig. 1, and the side parts of the jaws are tapered so as to be fully closed before the eye 4<a> reaches the tops of the jaws. In order to prevent sudden tensioning of the anchor chain 9 from breaking the leg of a captive animal a cushioning spring 14 is used. A link 11<a> on one half of the chain has a bearing at 11<c> for a rod 12 attached to the other half of the chain, the spring 14 being in initial compression and, when the chain is tautened, being further compressed between the end of the link 11<a> and a plate 13 on the rod 12.

Title: Improvements in or relating to display devices
IPC: G09F27/00
Filed: 1928-07-19
Abstract: 321,923. Biggs, C. C. July 19, 1928. Reel and endless web apparatus; cylinders and like elements, rotating and osciltating.-An apertured casing containing a display surface is provided with a manually operable shifting means which when moved in one direction change the display, and when released causes the display to alter again. Fig. 1 shows a cylindrical casing 10 containing a roller 15 the display matter on which is seen through a window 11 which is part of a glass tube. The roller may be removable and is rotated, through an angle limited by a pin and slot, by a pull cord 22. The cord 22 actuates a pawl and ratchet, a return spring 20 acting through a pawl on the other side of the ratchetwheel turning the roller still in the same direction when the handle is released. Fig. 4 shows two operating strings passing round two discs 29, 30 in opposite directions. The discs are loose on the roller 15 and carry spring pawls 31, 32 which engage screw-heads in the roller. Pulling the combined string 22 causes the pawl 31 to rotate the roller clockwise and release of the string allows a spring to return the discs 29, 30 and cause the pawl 32 to turn the roller still further in the same direction. Fig. 5 shows a modification in which a shutter 35 is mounted on a disc 30 loose on the roller 15, so that when a cord 22 is pulled the shutter is retracted to display the roller which has been held stationary by a pawl 31, and when the cord is released the shutter is returned and the roller moved forward simultaneously by a pawl 32 on the disc 30. An endless display band mounted on drums may be substituted for the roller 15.

Abstract: 1526885 Polycarbonates; polyurethanes BAYER AG 25 May 1976 [27 May 1975] 21614/76 Heading C3R A polycarbonate containing aliphaticallybound OH end-groups is made by transesterifying a dihydroxyl compound (D) having aliphatically bound OH groups with ethylene glycol carbonate (C), ethylene glycol being simultaneously removed from the reaction mixture by fractional distillation, as an azeotropic mixture with an inert solvent (S) in which ethylene glycol is insoluble. Suitable solvents are listed 10-30% mol excess of (C) may be used. A transesterification catalyst may be present, many being listed. High MW polycarbonates are obtained if, after removal of (S) and any unreacted (C), some (F) still remains to be distilled off under transesterification conditions. A polyurethane may be formed by reacting a polyisocyanate with the polycarbonate.

Title: Improvements relating to photographic cameras
IPC: G03B17/52
Filed: 1965-05-21
Abstract: 1,078,630. Multiple-photograph cameras. INTERNATIONAL POLAROID CORPORATION. May 21, 1965 [June 2, 1964], No.21659/65. Heading G2A. A photographic camera for obtaining multiple images on a single photo-sensitive sheet comprises six lenses 20a, ..., 20f each associated with a diaphragm 66 and a behind the lens type shutter 68 so as to expose a different area of the sheet, which areas are defined by walls (60) Fig. 3 (not shown) within the camera forming six open ended compartments, the rear surfaces of the walls being slightly spaced from the sheet; six shutter actuating buttons 32a ,  ..., 32f; a common view-finder (46) Fig. 1 (not shown) and a common shutter resetting means. Depression of a button, e. g. the button 32f, rotates a spring 100 clockwise and tensions it thus allowing an arm 100b to move in a slot 110 and hence rotate a gear-wheel 94 clockwise by means of a pin 108 round which the arm 100b is wound. A gear 92 and the integral shutter blade 88 are thus rotated so as to move the shutter blade aperture 90 across the aperture in the diaphragm 66 to expose the sheet. Clockwise rotation of the wheel 94 also moves a flash actuator 98 into contact with the flash contacts 114. After all six areas of the sheet have been exposed the shutters are reset by depressing a lever (44) (Fig. 3) which lifts platforms 84, 86 on which the buttons 32 are 'mounted. A "defeat switch" is provided to prevent actuation of the flash means during resetting of the shutters. Capping means for covering the diaphragm apertures during recocking may be provided. The photo-sensitive sheet may be part of a self processing film assembly which is processed on withdrawal of the assembly between two rollers (not shown).

Abstract: 732,373. Thermally - actuated valves. BRITISH THERMOSTAT CO., Ltd. Aug. 31, 1953 [Aug. 29, 1962], No. 21788/52. Class 135. In a thermally-actuated valve inwhich the valve 1 screwing on the stem 11 is lifted off its seat 2 by, e.g. the thermal rod 35 acting on the stem, the valve is set to close at a definite temperature by turning the stem from the knob 16 through transmission means including, e.g., spindle 13, slotted arms 17 engaging radial projections 23 on a disc 24 loosely mounted on stem 11 and loaded by spring 33 to engage two diametrical axial projections on the disc with a pair of a number of peripheral serrations 26 in a plate 27 secured to stem 11, and the transmission means is adapted to enable the screw 11 to be rotated independently of the knob and spindle for varying the range of adjustment of the valve. The disc rotates between two spacer washers 28, 29 non-rotatably but slidably mounted on the stem and having a screw-driver slot 38 whereby, after removing the knob 16 and screw 15, the disc 24 can be depressed against spring 33 out of engagement with the plate 27 and the plate and stem rotated so that other serrations engage the disc and the valve operates within a different temperature range. The valve is prevented from rotating by engag. ing a casing stop which also acts as a limit stop for the knob. The casing is formed by two nested cups 3, 4, secured at their bottoms to a sleeve 9 carrying the thermal rod and tube. Specification 689,142 is referred to.

IPC: F16B19/10
Filed: 1952-09-02
Abstract: 734,604. Rivets and bolt hole &c. bushes. NORTH AMERICAN AVIATION, Inc. Sept. 2, 1952, No. 22066/52. Class 89(1). [Also in Group XXII] Relates to high strength tubular rivets for use in blind riveting and consists in a rivet having a uniform bore for the greater part of its length, e.g. to the point 12, Fig. 4, beyond which the diameter reduces forming a curved wall of radius R considerably greater than that of the bore and struck from a centre located as at 13. The rivet has a flange 9 to form either a countersunk or an ordinary head and the bore has a countersink 10 and raised rim 11. The rivet is inserted in the plates &c. to be connected and a pin 1, Fig. 3, of diameter equal to that of the bore 3 but having an end 8 with a sharper curvature than that of the bore, is driven in expanding the rivet beyond the far side of the plates. The pin has a head formed at 7 to seat in the rivet at 10 and bevelled at 6 so that the rim 11 may be pressed down to retain the pin in place. The rivet may be of stainless steel and the pin of hardened steel and the curvatures are so selected that a radial stress is set up that strains the rivet beyond the elastic limit whilst the longitudinal strain is within it. The rivet end may have a series of grooves 16 of gradually increasing depth to increase the hold of the expanded end. The body of the rivet may be knurled or otherwise roughened. When the rivet is to be used as a bushing the head is left plain and the pin is formed without head and is driven right through or if the hole be blind a longer pin is used so that it may be withdrawn after driving.
