Title: Optical viewing instrument
Inventor: TAKAHASHI NAGASHIGE
IPC: A61B1/00
Filed: 1968-02-27
Abstract: 1,217,300. Optical apparatus. OLYMPUS OPTICAL CO. Ltd. Feb.27, 1968, No.36859/70. Divided out of 1,215,383. Heading G2J.

Title: Air heating apparatus
IPC: B23K3/02
Filed: 1974-08-22
Abstract: 1483257 Seaming non-metallic sheet material W S FORTUNE 22 Aug 1974 [22 Aug 1973 15 July 1974] 36873/74 Heading B5K [Also Division B3]  An air heating apparatus for plastics welding or plastics tube shrinking comprises an elongate heating rod including temperature sensing means for generating a control signal, a jacket body about the rod and having a nozzle outlet end and a rear portion, air inlet duct means adjacent the rear portion and means supporting the jacket body on the rod, the jacket body forming the outer wall of a chamber for heating air flowing between the inlet duct means and the nozzle outlet. In one embodiment a rod 18, Fig. 1 containing an electric resistance element carries at one end a temperature sensing element 22 for controlling the energy supplied to the element and carries at the other end a handle 14. A soldering tip 24 is located over the rod and a jacket 26 is arranged over the tip and rod, being held by a locking collar 36 on the rod, to form a chamber 28 through which air is passed from a duct 38 to a nozzle about the soldering tip. A helical spring 30 between the tip and jacket provides an elongated helical path for the air flow which may be derived from a mains supply, a hand operated bellows, bicycle pump or even the operator's mouth. In a modification the soldering tip is not employed. In another embodiment a further duct 52, Fig. 3 is suported on the jacket 46<SP>1</SP> of a tool similar to that of Fig. 1 this duct having a nozzle 60 directed towards the area to be worked on and being connected to a source of cold air to produce a thermal shock cooling or to a vacuum to draw ambient air away from the work area for cooling or to remove gaseous pollutants. In a modification the further duct surrounds the jacket to form an annular space between duct and jacket, hot air being supplied from the inner nozzle to shrink insulation tubing to a terminal of a multiprong connector while cool air is drawn or blown over adjacent terminals by the outer duct. The soldering tip may be omitted from the apparatus of Fig. 3 and its modification and instead of a helix between the heating rod and jacket foramenated ceramic material or stainless metallic wool may be used. In another embodiment a metal jacket 66, Fig. 6 is supported from a plastics bush 68 slidably disposed about a heating rod 18 carrying along the rod 18 by an operator pushing a flange 80 on the bush, a spring 92 in a bore of the bush providing positional control. Air is supplied through a duct 42 to flow about the rod 18 to emerge from the nozzle 100 formed by the jacket which latter may carry protective insulating material, e.g. silicone rubber or glass fibre. The insulating material may enable the tool to be moved through a group of insulated wires by moving them aside to allow the soldering tip to solder a terminal. Cleaning agents such as alcohol-water solutions may be atomized by air and carried with air through the jacket.

Title: Improvements relating to thief alarms
Inventor: WILKINS DAVID LEONARD WALTER
IPC: G08B13/02
Filed: 1958-11-17
Abstract: 858,599. Theft alarms. GLOBAL INDUSTRIAL CONSULTANTS Ltd. Oct. 14, 1959 [Nov. 17, 1958], No. 36923/58. Class 118 (1).  A theft alarm comprises an attachment for fitting to a container of gas under pressure having a spring- operated member for piercing the container, a trigger mechanism for releasing the piercing member after the spring has been stressed, and a sound-emitting device operated by gas under pressure released from the container. In operation a safetycatch 36 is withdrawn from a depression 37 and the attachment is set by withdrawing, by means of a knob 11, a hollow needle member 12 against the pressure of a spring 17. The needle 12 is latched in this tensioned position by depression of a plunger 19, which in turn is retained in the safety position by the insertion of a pin 39 in a bore 40. Finally, the attachment is screwed on to a cylinder 3 of gas under pressure. The device may then be fixed in position in a bag or case with the pin 39 protruding through a hole. When the bag is in use, e.g. for carrying money, the safety-pin 39 is withdrawn and the plunger 19 held down by the thumb. If the bag is snatched, the spring-loaded plunger 19 is released and rises, allowing the needle 12 to be driven by the spring 17 through the seal in the neck of the gas cylinder 3. The escaping gas passes through the hollow needle 12 and, via a cross-bore 44 (Fig. 4, not shown), through a throttle passage 13 to operate a siren 16. When the plunger 19 rises, its shoulder 25 completes an electric circuit (Fig. 2, not shown) to ignite a smoke generator 27. The alarm device may also be used to protect safes, buildings, or mail vans by mounting it so that the plunger 19 is released when the door is opened.

Abstract: 619,626. Filters; filtering-media. GENERAL MOTORS CORPORATION. Dec. 17, 1946, No. 37092. Convention date, Jan. 18. [Class 46] A filter element comprises a central tube 43, Fig. 3, having radial apertures, a double layer of paper 56 wrapped spirally about the tube and containing a manifold 65, Fig. 5, within its innermost convolution, the manifold having tongues 70 bent from openings therein and extending through one layer of paper and through the tube apertures to hold the paper to the tube and permit communication between the space within the convolutions of the paper and the space within the tube. The paper is folded and stitched at the middle to form two layers separated by a metal mesh element 63 which is clamped along one edge by the manifold 65. The convolutions of the filter element are spaced at the top and bottom by strips of corrugated paper 83. The filter element is assembled on a centre post 19, Fig. 1, in a casing 5 between sealing members, each formed of two coaxial flanged sleeves 45, 47 with a sealing ring 49 between them, the lower member ,resting on a shoulder 53 on the post 19 and the upper being held in contact with the tube 43 by a spring 55. Oil enters the casing at 13, and passes through the layers of the paper into the space partly occupied by the separator 63, and finally reaches the manifold 65, whence it passes into the annulus between the tube 43 and post 19, then through the ports 31 and bore 27, to the outlet 29. A spring-loaded by-pass valve 41 communicates with the inlet oil pressure through bore 33 and ports 35, and with the outlet oil pressure by the valve bore and ports 37.
