Abstract: 499,496. Tumbler switches. TUCKER & CO., Ltd., J. H., and FUKE, F. C. July 24, 1937, No. 20508. [Class 38 (v)] A tumbler switch has means whereby a movable contact is caused to take a period of rest after a small initial movement and before its final complete separation from the fixed contact to minimize sparking in A.C. circuits. A dolly l operates through gearing l<1>, k<5> and a quick action spring m, a cam k which has a step k<3> joining two surfaces k<1>, k<2> whose profiles are arcs of circles concentric with the pivot of the cam k. Contacts j<1>, j<2> are held together by the engagement of the cam edge k<1> with a roller j<3> on a spring contact member j. With rotation of the cam k, the roller j<3> first moves up to engage the cam edge k<2> and open the contacts j<1>, j<2> a short distance, and then moves a much greater distance on engaging cam edge k<4> to complete the contact separation. Fig. 1 shows a two way switch wherein a stepped cam surface on each of two spring contact members b, d is engaged by a roller c<1>, c<4> on a lever c which is moved with a snap action by a lever operated spring loaded toggle mechanism.

Title: Improvements in or relating to copolymerisation products
IPC: C08F214/00
Filed: 1943-12-08
Abstract: Copolymers of vinyl chloride or of vinylidene chloride with a diester of endomethylene tetrahydrophthalic acid are prepared by subjecting the mixture to the action of a catalyst and/or heat and/or actinic light.  The process may be carried out in single phase or in emulsion and preferably in the presence of an inert solvent or in an oil-in-water type emulsion.  Specified catalysts are benzoyl or crotonyl peroxides and ammonium persulphate.  The preferred amount of the diester is from 5 to 50 per cent by weight of the chloride. Specified esters are the diethyl, dibutyl, dihexyl and di-2-(ethyl)-hexyl esters-the longer the carbon chain of the alcohol radical the better the flow properties and the lower the softening point.  Plasticisers such as dibutyl phthalate and tricresyl phosphate may be present.  The sodium salt of sulphated cetyl alcohol is specified as an emulsifying agent.

Abstract: 1470653 Making bottom folded bags; seaming NATIONAL PETRO-CHEMICAL CORP 6 June 1974 [1 May 1973] 20676/73 Headings B5D and B5K In an apparatus for forming bottom folded bags, Fig. 14, lower and upper grippers 56 and 114 which grip a side gussetted bag section at lower and upper side edges GEL and GEU adjacent a sealed end S, are movable at different speeds in the longitudinal direction of the bag section to fold the bottom. The lower grippers are moved faster than the upper grippers when the sealed end S is the leading end, and the upper grippers are the faster when the sealed end S trails. In the embodiment shown the slower moving upper grippers 114 are inclined upwardly in the direction of feed of the bag sections, and bars (160) Fig. 15 (not shown) which are carried with the lower grippers, can lie in the top walls of the bag sections to define edges about which the top walls are folded during the bottom folding. The lower grippers may also carry a spacer (162) Fig. 15 (not shown) to open the gussets. In operation of the apparatus, guides 61 open the gussets in a web which has been subjected to flame treatment and printed on, and guide the lower grippers 56 which are carried by chains 54, into engagement with the lower edges GEL of the web. Heated sealing bars 62 and back-up bars (68) Fig. 1 (not shown) which are mounted between respective conveyor chains 64 and (70) Fig. 1 (not shown) for movement with the web, then transversely heat seal the web at spaced intervals. Adjustable pressing bars (76) Fig. 8 (not shown) are provided behind at least the heated sealing bars 62. The bag sections are severed from the sealed web by a rotary cutter and opened by a blast of ionized air from a nozzle 98 to facilitate the gripping of the upper edges GEU by the grippers 114. After the bottom folding, brushes 144 deaerate the bags prior to the bags being pressed by pressing belts (148, 157) Fig. 2 (not shown). The finished bags are stacked and the resulting bundle wrapped.

Mortar bomb or rocket propelled missile P is launched by means of a propellent charge L housed in a support S, which support is introduced into a launching tube T through the muzzle ahead of the missile P. The support S comprises a perforated tube 1 secured in a base 2 which houses a firing-pin 3 for actuation by a percussion member a to fire the cartridge containing charge L. At its forward end tube 1 is screwed to a body 6 which is itself screwed on to a tube 8 surrounding an obturating and igniting device b for the self-propulsion means of the missile. Housed in the body 6 is a propellent charge 11 in communication with nozzles 12.

July 27, 1933, No. 21164. [Class 40 (v)] A short or ultra-short wave radio receiver comprises a frequency changing stage in which the received signals are applied to the anode of the valve while local oscillations of longer wave-length are applied to the grid, the anode potential being adjusted so that rectification occurs in the anode circuit. In the case of a triode valve the received oscillations are applied through a tuned circuit connected across anode and cathode or anode and grid, the local frequency source being between grid and cathode, (Figs. 1 and 2, not shown). Or, as in Fig. 3, a dipole aerial 10, 11, of natural frequency equal to the received frequency is connected to anode and grid, the local frequency 9 and coupling impedance 7 being connected as before. To avoid oscillation in the anode circuit at the local frequency, a tetrode may be employed with the tuned circuit between anode and screen grid or anode and cathode, the local frequency being applied between control grid and cathode, (Figs. 4 and 5, not shown). Or a dipole aerial may be employed as shown in Fig. 6. A rectification stage may precede the frequency changer shown, and the output may be applied to an ordinary superheterodyne receiver.
