IPC: G01B5/08
Filed: 1956-09-19
Abstract: 816,075. Optical gauging-apparatus. RANK CINTEL Ltd. Sept. 19, 1957 [Sept. 19, 1956], No. 28643/56. Class 106 (2). The eccentricity of an approximately central hole in the end face of a cylindrical cup 2 is determined by rotating the cup rapidly about its axis of symmetry and examining the face containing the hole by means of an optically magnifying measuring instrument to determine the difference between the diameters of the fully lit and penumbral areas of the viewed field as a measure of four times the eccentricity. The cup 2 may be rotated at about 5,000 r.p.m. by applying compressed air to four sets of tangential ports 4, 5 in a metal block 1 bored to receive the cup with a slight clearance and provided with four tangential outlet ports 6. The hole in the block 1 is closed by a flat glass plate 3 so that the cup 2 can be illuminated from below by diffused light. A metal cup 2 could be rotated by a rotating electric field produced for example by three-phase electric currents of suitable frequency passed through multipolar windings on a hollow ferromagnetic member.

Title: An improved trap for rabbits or like animals
IPC: A01M23/30
Filed: 1927-10-27
Abstract: 304,828. Jones, W. Oct. 27, 1927. Animal traps.-An animal trap of the type in which a trapping member is actuated by a torsion spring and operates pivotally about the axis of the spring when the retaining member is freed, has the trapping member so shaped as partially to embrace the trapped animal and to hold the animal to the trap without injuring the animal. A transverse limb of the base 1 supports the torsional spring 2 one end of which is extended as a crank portion 10, bent into an arm 11, and continued as an arched trapping member 7. The trap is set by pressing down a pivoted bar 15 on the part 11 of the trapping member until the free end of the bar can pass under a hook 18 on a cranked extension 19 of a trip plate 5. In a modification in which the animal is intended to approach the bait plate longitudinally of the trap, the trapping member, which is arched to embrace the animal as before, is arranged transversely and is carried by two arms extending from the sides of the spring. In another form a transverse trapping member is carried by one central arm and the central arm as well as the trapping member may be curved to engage the body of the animal.

In a lubricating pump in which several discharge outlets 24 in the pump casing 1 lead to corresponding ducts 18 in a fixed conical seating 2 for a conical distributer 3 which is rotated to bring a duct 19 therein successively into register with the discharge ducts 18 and the duct 19 in the distributer 3 is in open communication with an axial bore in the distributer, constituting a cylinder for the pump piston 7, the piston is actuated by a member 10 arranged in a slot 4, 8 extending across the distributer and piston, with its centre portion engaging the piston and its ends in contact with a fixed ring 11 having a number of pairs of cam surfaces adapted to force the member and piston downwards to effect discharge. A lever 6 in the slot 4 in the distributer engages a pin 5 spanning the slot 8 in the piston to effect the suction stroke when the outer end of the lever is depressed by one or other of several cam surfaces 14a formed on screws 14 set in a fixed ring 13, adjustment of the screws varying the suction stroke to control the delivery of the pump. The suction operates through ducts in the seating ring 2 alternating with the discharge ducts 18 and communicating with an annular recess 22 underneath the ring 2, there being a single inlet port leading to the recess. The internal surface of the ring 11 carrying the screws 14 is grooved circumferentially and slotted radially to provide superposed lugs which are subsequently distorted to make the screws engage with considerable friction.

Title: Improvements in direct coupled amplifiers

IPC: H03F3/36
Filed: 1954-10-07
Abstract: 772,757. Valve amplifying circuits. SAUNDERS-ROE, Ltd. Sept. 30, 1955 [Oct. 7, 1954], No. 28916/54. Class 40(6) The anode supply voltage of a direct coupled amplifier is made up of two components, a highly stabilized component and a component directly proportional to the heater voltage. It is explained in the Specification that variations in the same sense of the heater voltage and the anode voltage produce opposite effects and that by arranging that the charges run in the right proportions the effects may be made equal. Fig. 2 shows a circuit for producing the required anode voltage. The stabilized component E1 is derived from a mains stabilized high tension rail through a cathode follower valve 12; the variable component E2 is derived from the main supply, from which the heater voltage is also derived, through a conventional rectifier circuit, and the resultant voltage Ebb = E1 + E2 is used for the anode voltage supply of the first as first two stages of the amplifier.

Abstract: 1,005,810. Grinding pick-ups. DECCA Ltd. July 26, 1963 [July 30, 1962], No. 29174/62. Heading G5R. A pick-up arm is provided with magnetic means for providing a force acting to oppose any side thrust of the stylus against the wall of the record groove. In one arrangement, Fig. 2, the pick-up arm 1 carries a disc 9 concentric with its pivot and magnetized across a diameter; a fixed permanent magnet 10 erts a counter-clockwise force on the disc by magnetic attraction, Fig. 2, or by magnetic repulsion, Fig. 3 (not shown). The magnet 10 may be adjustable vertically to vary the force, Fig. 4A (not shown), or may be replaced by two longitudinally adjustable bar magnets, Fig. 4B (not shown). In another arrangement, Fig. 5 (not shown), the pivots for vertical movement of the pick-up arm are carried by a bar magnet attached to the arm and co-operating with a bar magnet in a fixed base. In an automatic record player the magnets may be mounted beneath the base-plate, Fig. 6 (not shown). In a further arrangement, Fig. 7, the blade-shaped pivot 18 of the pick-up arm has a needle point rotating and rocking in a conical socket in a fixed pivot member 20, which may be a cup filled with a viscous fluid. The pivot 18 is mounted in a cylindrical cup 19 which carries a ring-shaped magnet magnetized across a diameter. Co-operating bar magnets 10 are mounted in a stirrup-shaped element 21 which extends over rather more than 180 degrees of arc and is a smooth sliding fit over the exterior of the pivot base 13. The element 21 may be of polyethylene.

As shown, the non-rotatable axle 1 is formed with a torque flange 5 to which is secured a pressure plate 8, bolts 12 extending through the plate, a back plate 9 and a torque tube 13; spring or Belleville washers 14 are disposed about each bolt and between the plate 9 and the tube 13. The latter is secured to the plate 8. A plurality of brake discs 15 have outer peripheral notches for receiving keys 16 on the wheel 2 and secondary brake discs 17 have notches for engagement with splines on the tube 13. An annular cylinder 19 and piston 21 operating on the bolts 12 cause the plates 8, 9 to be drawn together. Each disc may be of carbon particularly in the form of graphite or amorphous carbon, or carbon compounds such as boron, silicone and titanium carbide. In addition to the carbon base other ingredients may be used such as boron, tungsten silicone carbide or titanium, binders, fillers, reinforcing fibres and high temperature strengthening agents such as tungsten metal or silicone carbide. To prevent oxidation of the discs around the notches therein a coating covering the non-rubbed surface of the disc is applied as by slurry techniques, electrolysis, electroplating, plasma spray, spluttering and vapour depositions, and typical coatings include electrolysis nickel and electroplated chrome, electroplated nickel and chrome flash, chromium and chromium oxide, silicon carbide, silicon metal, electroplated nickel over copper and electroplated cadmium over nickel. For strengthening the load bearing portions of the discs, straps 32 riveted to the area in the vicinity of the notches are used; the discs 30 may consist of segments 30a, 30b and 30c.
