Title: Improvements in or relating to pump units
IPC: F04B9/06
Filed: 1954-10-29
Abstract: 782,838. Reciprocating pumps. CANDY FILTER CO., Ltd., and THOMAS, W. D. J. Oct. 24, 1955 [Oct. 29, 1954], No. 31321/54. Class 102(1). A pump plunger 10 is actuated on the suction stroke by mechanism comprising a rod 20 connected to a ring 20a mounted for eccentric rotation round a drive shaft 21, and passing through a bore in a pin 19 transversely pivoted to the plunger 10, and having a rebate 22 engageable with a detent 23 so that while the rebate 22 engages the detent 23 due to rotation of the shaft 21 the plunger 10 makes a suction stroke and a spring 26 is compressed. Further rotation of the shaft 21 causes the rebate 22 to clear the detent 23 and the spring 26 forces the plunger 10 to make a working stroke. The length of working stroke is adjusted by means of a stop nut 27. The commencement of the working stroke may be varied by adjusting the height of the detent 23. In a modification a spring- loaded plunger prevents the plunger 10 making a working stroke until the spring-loaded plunger is withdrawn. In a modified construction, a large diameter piston is secured to the plunger 10 and the spring 26 acts directly on this piston. Combinations of these pumps may be mounted on a common drive casing and be driven by a common shaft and deliver to a common outlet, each drawing, if desired, from a separate supply. the timing of each pump being set as required. A free wheel may be incorporated in the drive to prevent reversal of the shaft 21.

Abstract: 520,983. Two-part couplings combined with switches. MYERS, J. W., and ROESCH, S. J. Nov. 7, 1938, No. 32253. [Class 38 (i)] [Also in Group XXXVII] In electric cooking apparatus a manually adjustable thermostatic switch in the heating circuit, receives heat principally from a cooking vessel but also from part of the apparatus, to control the degree of ebullition of the contents of the vessel. A framework 3 carries two annular heaters 1, 2 heat insulated on the underside at 4, and also an insulating base 6 on which are three spring contact strips 7 to which electrical connection is made. A removable control unit 12 has a base 14 under which are three contacts 18 which rest on contacts on the end of spring strips 7 which provide a resilient mounting for the unit 12 which is located in position by two pins 11, 11a. From contacts 18 connection is made through the base 14 to three contacts 21, 24 mounted above the base on strips 19, 22. Two switches which control the two heaters 1, 2 respectively, are provided, each of which comprises a bimetallic strip 27 which is fixed at one end 32 to the underside of a top plate 33 of the unit 12 and carries pivotally at the other end a lever 28 having a universally mounted contact 31 which is urged by a spring 29 to bridge one pair of the fixed contacts 21, 24. Upon bending of the bimetallic strip the end of the lever 28 engages one of the cams 34, 35 and rotates to open the switch, the position of the cams being altered by rotation of a setting knob (Fig. 9, not shown), through a flexible shaft. In the position shown in Fig. 3, shoulders 40 on the unit 12 engage the heater 1 to allow direct thermal conduction to the bimetallic strips, but on placing a utensil on the heater the unit 12 is pressed down against the springs 7 to break the direct thermal conduction, the thermal switches now being mainly influenced by heat conducted from the base of the utensil, but partly by radiation and convection direct from the heaters which provision allows control at different rates of ebullition although the utensil may remain at the same temperature. In a modification described, rods fixed to the base 6 holds the contacts open when the utensil is removed.

Title: Process for making silicon polymers from organo-substituted silicanes
IPC: C08G77/08
Filed: 1945-11-29
Abstract: Polymers are produced by treating under anhydrous conditions with acids having at least one acid hydrogen atom linked to oxygen, a mono-organo silicon compound of formula <FORM:0609324/IV(a)/1> or a mixture of such compounds, where R= an alkyl radical and R1, R2 and R3= alkyl or aryl radicals.  Suitable acids are sulphuric, phosphoric, boric, carboxylic acids, e.g. mono-, di-or tri-chloracetic acid or salicylic acid, or partial esters of polybasic acids.  The reaction mixture may be heated. Reaction may be performed in presence of a solvent for the monomer or the product, e.g. benzene or toluene.  The reaction may be accelerated by addition of anhydrous hydrochloric acid as catalyst.  Preferably, acids are used which form during the hydrolysis low boiling esters which may be removed by distillation.  In example (1) dimethyl dimethoxy silane was refluxed with boric acid, methyl borate distilled off, the polymer dissolved in benzene and freed from boric acid by filtration. In example (2) a solution of dimethyl dimethoxy silicane and phenyl trimethoxy silicane in toluene was stirred with sulphuric acid. The methyl hydrogen sulphate layer was separated and the toluene layer washed with sodium bicarbonate, and distilled water. Evaporation of toluene left the hard clear solid polymer.  In example (3) a mixture of dimethyl dimethoxy silicane and trimethyl monomethoxy silicane was treated in toluene with trichloracetic acid.  Solvent and methyl chloroacetate were removed by distillation.  In example (4) diphenyl dimethoxy silicane was hydrolysed with salicylic acid.  The Provisional Specification describes the treatment of di-n-hexyl dimethoxy silicane with boric acid.
