IPC: A62B18/04
Filed: 1961-06-28
Abstract: 931,129. Goggles. P. FRANKENSTEIN & SONS (MANCHESTER) Ltd. May 8, 1962 [June 28, 1961], No. 23334/61. Class 97 (1). A personal face protector comprises a panel of tough transparent sheet material, flexible enough to be rolled or folded and of a stretchable nature, and a collapsible frame secured round the periphery of the panel and attachable to the wearer's person at shoulder or chest level, the remainder at least of the frame being inflatable to extend the panel and effect its erection in front of the wearer's face. As shown, a frame B, inflatable from a bottle C of compressed gas, surrounds a panel A of transparent material, e.g. polyvinyl chloride, and which, on inflation, rises to a position behind the wearer's head and pulls the dome-shaped panel into a position protecting the wearer's face. When not in use the panel and frame may be folded and secured by quick-release flaps H. Specification 851,725 is referred to.

Jointing.-A method of applying sheet metal jackets, e.g. of alloy steel to foundation bodies or workpieces a such as shafts, rolls, tubes, drums and the like is characterized in that the jacket b is drawn cold over the workpiece and thereupon by appropriate local heating and mechanical pressure over a restricted area and cooling is progressively shrunk thereon. A portion of the jacket is heated by a burner C, after which the heated portion is pressed on to the workpiece by a roller d and thereafter cooled by a jet e the burner, roller and cooler being mounted on a yoke f carried by a slide g on the machine. The workpiece is mounted on the machine between a headstock k and a tailstock l, rotated and the yoke traversed so that the roller moves along a helical path over the surface of the jacket progressively pressing the jacket on to the workpiece. On being cooled the jacket shrinks tightly on to the workpiece.
Patent GB-831418-A (GB)
Title: Refining of lead
IPC: C22B13/06
Filed: 1958-07-22
Abstract: Lead contaminated with 0.05-15% of impurities consisting mainly of sulphide is treated, at a temperature in the range 330-650 DEG C., with hydrogen chloride or ammonium chloride until the hydrogen sulphide content of the gases evolved is substantially nil.  An excess of the refining agent is preferably employed, e.g. 5-50 times the amount theoretically required.

Title: Improvements relating to power-assisted mechanisms
Inventor: GARTHWAITE ERNEST
IPC: A61B6/00
Filed: 1953-09-04
Abstract: 749,855. Electric follow-up systems. MARCONI INSTRUMENTS, Ltd. Sept. 3, 1954 [Sept. 4, 1953], No. 24494/53. Class 40(1) [Also in Groups XX and XXXVII] In a power-assisted control system for positioning a head carrying the fluorescent screen of an X-ray table (see Group XX), the power supply is provided by a reversible motor 13 the torque of which is automatically reduced when the head has started and its intertia has been overcome. The motor is supplied from an alternating- current source 31 through a main switch 32 which also completes a circuit to electric locks effective when energized, to free the head for movement relative to the table. The head carries an operating handle 19, so that, with the switch 32 closed and' handle 19 in the neutral position, a twopole change-over relay RR/2 and a timedelay relay RD/1 are both energized. Pressure applied to the handle for movement in the forward direction operates switch 29 to de-energize relay RD/1 and to energize the motor in the appropriate sense, movement continuing as long as the switch 29 is maintained operated. A predetermined time after the motor starts, the relay RD/1 drops out and its contact rd1 operates to increase the value of resistance 37 in the motor circuit. If power is applied to the operating handle in the opposite direction, the switch 28 is effective to interrupt the circuit of relays RR/2, RD/1 so that the motor field winding is reversed relative to its armature and, as before, the relay RD/1 drops out after a time interval to reduce the motor power. When there is reversed pressure on the operating handle whilst the head is still in motion. the time-delay feature of the relay RD/1 is rendered ineffective and reversal takes place at low power. The motor 13 may be of the split-field type arranged for three-wire reversing, in which case the relay RR/2 is dispensed with.

Abstract: 223,606. Index Visible, Inc., (Assignees of Day, W. H.). Oct. 19, 1923, [Convention date]. Cabinets; locks and fastenings.-A cabinet for filing index cards in known manner in shallow drawers C comprises a separately constructed outer casing A, which can be slid over an inner casing B so as to form fireproof enclosures therebetween. The inner casing B is shown ready for assembly in Fig. 6, and comprises base portions 21, 22 in which standards 26, 27 are mounted. The latter support the upwardly bent angular portions 33, 34, 35, 36 of division members 29, which act as drawer guides and are stiffened by being doubled at the front end of the drawer, the edge 30 of the doubled portion being passed into a V- shaped groove 31 in the upper part. The drawers C comprise each a body 60 and a follower 61 hinged thereto so as to allow the body to hang downwards when withdrawn from the cabinet, as shown in Fig. 1. The body is formed of a metal sheet having upwardly bent side edges and sloping front and rear portions 64, 66, the front edge being bent vertically downwards and covered with an angular tongued strip 72, in which an index card is mounted. The follower 61 comprises a sheet having its forward edge bent round a hinge pin 67 secured to the bent back edge of the body, and a projecting portion 83 which, by contacting with a similar projection 84 on the body, prevents the follower from rising when the body is swung downwards. The drawers are locked in position by the engagement of flanges 89 on the followers by the downward motion of a bar 48, which is operated by rotation of the cylinder lock 52 on the end of a rod 50 mounted between the base portions 21, 22. A false top 39 is welded by its sides to the top division member. The drawer is normally prevented from being wholly withdrawn from the cabinet by ears on the follower engaging in slots 55 in the division members, but may be wholly withdrawn by raising the end of the drawer body and thus preventing engagement of the ears in. the slots.
