Title: Method and apparatus for measuring thickness
Inventor: ALLEN HENRY HANS
IPC: G01B5/06
Filed: 1955-07-08
Abstract: 791,382. Linear dimension gauges; recording- apparatus. BRITISH CELANESE, Ltd. July 5, 1956 [July 8, 1955], No. 19813/55. Addition to 759,196. Classes 106 (2) and 106 (4). In apparatus for measuring and recording variations in thickness of a flexible sheet material 55, comprising a stationary thickness gauge 14, having a movable foot 15, a stationary anvil 8, advancing mechanism 6,' 5, 4, for forwarding the sheet intermittently between the foot 15 and the anvil 8, and means 58 for urging the foot towards the anvil, as described in the parent Specification, means 19 are provided to withdraw the foot 15 out of contact with the sheet 55 before each intermittent movement of the sheet and releasing it into engagement afterwards. The strip of recording material 34, is advanced by pulleys 48 and gearing 47 in accordance with the movement of the material 55 and a pen 25 records, on the strip 34, variations in the displacement of the foot 15 from the anvil. A cam 26 counterbalanced by a weight 29 acts on a pivoted lever 19 which engages a button 18 on the end of the plunger of the gauge 14. This action disengages the foot 15 from the material 55 at the appropriate time and then releases it. The intermittent movement of the apparatus is controlled by a rubber eccentric 4 on a driving wheel 5 driven by a belt 6. This eccentric engages a drum 1 around which the material 55 is placed, the drum being braked by a friction pad 7 to prevent over-running. A crank 46 on the driving wheel 5 moves a horizontal arm 41 pivoted at 42 by means of a cord 43 running round pulleys 45, 42, 44. This arm 41 is connected to the upper supply roller 32 of the recording strip 34 and moves the strip away from the pen 25 at the appropriate time. A cord 51 passing round a pulley 52 and connected to the free end of arm 41 operates on the cam 26 to disengage the foot 15 of the gauge 14 from the material 55. Between the drum 1 and the anvil 8 are a pair of de-electrifying pads 59, which relieve the film of any electrical charge it has accumulated and also of any dust which might observe the accurate reading of the gauge.

Title: Improvements in or relating to methods of treating thermoplastic material
IPC: B29B13/02
Filed: 1953-07-17
Abstract: Thermoplastic sheet material is differentially softened by radiant heat by locally treating it with or applying thereon a paint or other material either having a high absorption factor or being highly reflective for the radiation used, or by using both absorbing and reflecting materials in different areas, the sheet being then distorted at the softened parts to produce shaped articles.  By applying coated patterns to thermoplastic blanks and, after heating, clamping the blanks around their peripheries and applying pressure or vacuum to one surface elaborate shapes may be produced, simple moulds being used additionally if desired to limit the maximum deformation of the blanks.  The thermoplastic material may be polymethylmethacrylate and the source of radiant heat may be electric lamps while the absorbent material may be black paint and the reflective material may be white or aluminium paint or a bright metal mask.  Specifications 696,563 and 707,160 [both Group XVI], are referred to.

Filed: 1938-07-06
Abstract: 516,872. Valve amplifying circuits. SNEATH. O. B. July 6, 1938, No. 20043. [Class 40 (v)] A manual volume control consists of a potentiometer constituting a variable resistance in series with the signal input to a valve and to which negative reaction is applied and a variable resistance shunting the whole or a part of a winding of an audiofrequency transformer. The Figure shows an arrangement in which the feedback is fed through a condenser C1 and resistance R1 to the potentiometer R2, part of which varies the voltage fed back to the grid circuit, while the other part forms a variable resistance shunting a part of the input transformer winding. The range of the volume control can be further extended by including some positive reaction in the grid circuit. Frequency selective circuits may be used to vary the relative amplification of different frequencies, e.g., the variable resistance may be shunted by a condenser or a resistance shunted condenser may be included in the cathode circuit.

Title: Lithium soap lubricating grease
IPC: C10M123/02
Filed: 1975-05-15
Abstract: For the preparation of a lithium soap lubricating grease from a lubricating oil and a lithium soap of a hydroxy-fatty acid and a boron compound as a thickener providing consistency, the thickener is prepared by reacting an ester of 12-hydroxystearic acid and boric acid with lithium hydroxide and mixing the product with a lubricating oil. The lithium soap lubricating grease thus prepared contains preferably 5 to 20% by weight of the lithium soap of 12-hydroxystearic acid and 0.1 to 3% by weight of boric acid, for example in the form of dilithium borate or monolithium borate. Preferably, the methyl ester of 12-hydroxystearic acid is used. This allows a comparatively inexpensive production of lubricating greases having a dripping point higher than the conventional one.

Title: Improvements in or relating to hypodermic injector
IPC: A61M5/24
Filed: 1955-07-18
Abstract: 777,302. Hypodermic infection devices. SCHERER CORPORATION. R. P. Julv 18, 1955 [Sept. 7, 1954], No. 20760/55. Class 81(2) The power means for operating a needleless hypodermic injector comprises a number of pairs of diametrically placed springs. The appliance described has a primary plunger 50 and a secondary plunger 60, so actuated by spring means bearing on a disc 70 that the plunger 50 strikes the ampoule piston 46, over a small area, thereby giving an initial high pressure injection, and thereafter the disc 70 engages the head 64 of the secondary plunger 60 so that both plungers more downward together, bearing on the whole area of the piston 46. This arrangement is similar to that described in Specification 705,515. However, in the present apparatus the power springs are arranged in diametrical pairs around the central axis, each pair consisting of two concentric, oppositely wound springs 80, 81, and having a guide rod 71a at their centre. The winding stem 74 has a double thread and is rotated, to compress the power springs, by the winding head 14, and is latched, prior to winding, by wedge latches 82 engaging under a pin 76. These wedges are withdrawn by pressure on a knob 90 to allow their outer ends to' pass into recesses 92. The primary plunger 50 engages the sleeve 72 with a single thread only so that fine adjustment of its position in relation to the ampoule piston 46 can be obtained. If the diametrically opposite springs are of different periodicity the tendency to eject the medicament with a high frequency surge is minimized. A dosage sleeve 12 is threaded on to the body 10 so that any predetermined quantity of medicament can be expelled prior to the injection. It is retained in various set positions by a spring arm 15 engaging in locating notches.
