Title: Improvements in or relating to lightweight concrete
Inventor: WILTSHIRE JOHN FRANCIS
IPC: C04B38/04
Filed: 1967-02-23
Abstract: 1,212,195. Lightweight cement. J. F. WILTSHIRE. 23 Feb., 1968 [23 Feb., 1967], No. 8771/67. Heading C1H. Lightweight concrete is made by moulding and hardening a composition comprising Portland cement or cement made by fusing lime with alumina, water, and a particulate thermoplastic material and then extracting the thermoplastic from the hardened composition. Suitable thermoplastic materials are glass and polystyrene or polyvinyl chloride which can be used as the expanded materials. The thermoplastic material is extracted in whole or in part by melting, e.g. with steam in an autoclave, or by dissolving out with a solvent. Pulverized fuel ash, sand, gravel, artificial aggregate, pigments, aeration additives, plasticizers or hardeners can be included in the compositions.
Patent GB-571051-A (GB)
Title: Production of air drying and stoving finishes
IPC: C09F5/06
Filed: 1943-06-02
Abstract: Producing air drying and stoving finishes by heating a varnish comprising castor oil and a natural acidic resin, at a temperature of 280 DEG  to 310 DEG  C. whilst a rapid stream of an inert gas is passed through the heated varnish.  Preferred resins are the rosin-modified phenolic resins such as esterified or unesterified phenol-formaldehyde rosin complexes, rosins hardened by the incorporation of a metallic oxide such as magnesium, zinc or calcium oxide, maleic anhydride-rosin addition products, or modified copals or dammars.  Rosin itself may also be used.  As inert gases there may be used carbon dioxide, nitrogen and waste furnace gases of low oxygen content.  In examples 1 to 8, a rosin modified phenol-formaldehyde resin is used; in example 9 an esterified rosin modified phenol-formaldehyde resin; in example 10 rosin; and in example 11 rosin and magnesium oxide.  The products are compatible with varnish-thinners, e.g. xylene, solvent naphthas, turpentine and white spirit, and can be pigmented or compounded.  Driers such as lead or cobalt driers can be added and the finishes can be hardened by stoving.

Abstract: 1,217,669. Tape recorders. A. & M. FELL (MFG.) Ltd. 19 Feb., 1969, No. 8897/69. Heading G5R. In a flight recorder, the bulk of a loop of lubricated recording tape is loosely wound as a flat spiral stack on a freely rotatable spool and a brake shoe bears against one flat side of the stack until it is disengaged by the operation of the tape transport system. As shown, a section of tape 10 connecting the inner and outer convolutions of the spiral tape stack (19, Fig. 2) is carried past a recording head 17 by a belt 9 driven by a capstan shaft 18, which extends through an aperture in the hub of the tape spool (21, Fig. 2) as described in Specification 1,217,667. A spring-loaded lever 14 wedges a brake shoe (46, Fig. 3) against the tape stack, to prevent tape spillage, until the increased tension in the tape 10 on its being driven acts on an idler pulley 13 to turn the lever 14 and release the brake shoe.

Title: Timing control for mechanisms

Filed: 1944-05-19
Abstract: 590,328. Paper towel dispensers. DEHN, F. B. (Towlsaver, Inc.). May 19, 1944, No. 9679. [Class 18] [Also in Group XXXII] In a paper towel dispenser or other mechanism in which an operation is repeated, means are provided whereby after completion of one operation the effecting of the succeeding operation is inhibited for a definite time period by an automatic device. In the towel dispenser shown delivery of towelling is effected by rotation of a member B, and such rotation is positively inhibited intermittently by means of a reservoir A pivotally mounted on member B and containing liquid or granular material such as mercury, water, glycerine, oil, sand &c and a control member E. In the position shown in Fig. 1, member B is held against rotation in delivery direction by contact of reservoir with a stop 14 fixed on the casing of the apparatus, but while in this position the mercury 8 runs from compartment 2 to compartment 3 through channel 5 in a definite time, so that when member B is rotated slightly in non-delivery direction under control of a pawl, reservoir A is freed from stop 14 and rotates about a pivot 1 under the weight of substance in compartment 3 so that delivery rotation of member B may be effected, the substance passing from compartment 3 to compartment 2 rapidly through channel 6 while the reservoir is in the lower part of its travel. Control by member E is effected by engagement of shoulders 20, 21 thereon with shoulders 18, 19 on an eccentric segment 17 of the member B. This control is such that the rotation of member B is constrained to be intermittent, the engagement of shoulders 18, 20 stopping the rotation until, by reverse rotation of member B by means of a handle, shoulders 21, 19 are engaged and shoulder 20 lifted out of the path of shoulder 18, when, on again reversing the motion of member B the delivery movement is unretarded except as to the action of the timing device. Specification 571,534 is referred to.
