Title: Welded double glazing unit
IPC: E06B3/66
Filed: 1949-12-20
Abstract: 665,977. Hollow glass blocks. PITTSBURGH CORNING CORPORATION. Dec. 20, 1949 [Dec. 28, 1948], No. 32578/49. Class 56. [Also in Group X] Double glazing units are formed by taking two flat panes, one very slightly larger than the other, heating them above the critical temperature, bringing them face to face with the larger pane uppermost but not quite touching the lower pane, heating the margins of one pane to weld them to the margins of the other pane and pulling the pane having the heated margins away from the other to provide a sealed chamber c as shown in Fig 4. The pane 15 having the heated margins is vibrated relatively to the other pane 16 to fillet the margins and to form an internal U-curved section 20. The panes are preheated in a portion 21, Fig. 6, of an oven and are conveyed by a carriage 35 to an intermediate chamber 22 where they are positioned by a centring device 49 ... 61 between a pair of complementary platens 41, 42 having recesses connected to suction for holding the panes to the platens. The heating of the margins is effected by the passage of current through conducting strips which are burnt away as the temperature rises and the glass becomes conducting. The upper platen is then vibrated. After formation the units are removed by a carriage 35a and transferred to an annealing rack 71. Small apertures are provided in one of the panes through which the units may be filled with dry gas, the apertures being subsequently sealed.

Title: Improvements in bottle corking apparatus
IPC: B67C7/00
Filed: 1930-11-01
Abstract: 370,891. Crown corking machines. WORSSAM & SON, Ltd., G. J. and FOX, D. P. S., Wenlock Road, Islington, London. Nov. 1, 1930, No. 32943. [Class 125 (ii).] In a rotary multiple-head crown corking machine, the crown cork is applied by pressure applied mechanically through springs at one end and pneumatically at the other. The bottle-supporting platforms J are mounted on plungers K housed in pneumatic cylinders K<1>, which communicate with a source of compressed air through a reservoir L. The crown corks, contained in a hopper M‹, gravitate through a shoot the top part M<1> of which is fixed to the hopper while the lower portion M rotates with the crowning head. The feed of the corks is governed by a spring-biased escapement device N carrying a roller N'. If a cork is not situated beneath the nose of a lever O, the releasing arm P moves it into the path of the roller N<1>, whereby the escapement device is moved to release another cork. The lower part of the upper shoot M<1> is hinged at M<2> to allow for movement in case of a jamb. The crowning heads are operated by rollers H on a cam track G the sealing and crimping pressures being independently variable by different spring loadings. The head may be adjusted as a unit by the screw adjustment S, S<1>, T.

Title: Improvements relating to plant for drying or like treatment of garments
IPC: D06C5/00
Filed: 1952-12-30
Abstract: <PICT:0733377/IV (c)/1> <PICT:0733377/IV (c)/2> A treating plant for textile or knitted articles comprises carrying forms for the articles to be treated which are passed by means of a pneumatically driven conveyer into and out of a treating chamber.  Figs. 1, 2 and 3 show a machine for use in finishing knitted garments which are passed in sequence through the machine and subjected to the action of steam and then hot air. The garments are mounted on forms 2, 3 and 4 which are carried by a conveyer comprising an endless chain 1 which is moved in steps so that a form passes first into a steam chamber having a casing 17 and doors 16, and then into a drying chamber 27.  The conveyer chain 1 passes round a rotary table 5 which is driven by a chain 13 so that when a form moves into the steam chamber the chamber is sealed by doors 16 which have felt inserts 18 pressing against the inner surface of casing 17.  When steam valve 24 is opened steam passes from distributer 21 upwards through the chamber 17 over the form-mounted garment.  The garment next passes into drying chamber 27 into which air is forced by blower 29 and <PICT:0733377/IV (c)/3> heated by element 31 which is transversed by steam from line 23. The garment finally passes into the position shown at 2 where it is removed from the form and a further garment to be treated is put into place.  The impulsion of the driving chain 13 is carried out pneumatically from a main compressed air motor 33 (Fig. 3). Compressed air is forced via a reversing valve 45 alternately into the two sides of piston 39 which thus moves alternately to left and right and thus imparts a stepped movement to chain 13 by means of a driving pawl 38.  Each of the outlets from reversing valve 45 contains a needle valve 51 which enables the rate of travel of piston head 46 to be adjusted and thus the speed and period of dwell of chain 13 to be controlled.  The distance of travel of piston 39 in either direction is controlled by limit switches in the form of change-over valves 54, 55.  A cam 61, Fig. 3, controls the supply of compressed air to assembly 68 and 69 so that when the garment to be treated is correctly situated in the steam treating chamber the spring loaded cam 72 enters a notch 74 in rotary table 5 to hold it stationary and the steam valve 77 is opened to let steam into the treatment chamber.

A remote control circuit for selectively switching individual electric or electronic components, or groups of such components, e.g. piezoelectric crystals Q1-Q6 into connection with a controllable circuit, e.g. a tank (tuning) circuit connected to points A, B, comprises first diodes D1-D6 which are series-connected with each of the components, or groups to be switched, the biases to said diodes being varied and all the series-connected circuits being connected in parallel to one another and the controllable circuit. There is further provided a second diode, i.e. diodes D11-D16, connected in parallel to each component or group to be switched, a control voltage being applied to the mutual connecting points P1-P6 of each pair of first and second diodes, the mutual connecting point, e.g. P1 being connected to one terminal being connected to one terminal of the control voltage source in the circuit of the selected component, e.g. crystal Q1 to be switched, whereas the connecting points, e.g. P2-P6 of the circuits of components not selected for switching are connected in common to the other terminal of said source. In the embodiment the connecting means comprise remote switches S1-S6, each with its moving contact connected to one of the mutual connecting points P1-P6 via a choke L1-L6 and decoupling capacitor C1-C6: in each switch one fixed contact is connected to the + 10 V source and the other via a resistor R1-R6 to the negative terminal of the source. A resistor R7 is connected across terminals A, B. The arrangement is such that when any one of the series diodes, e.g. D1 is biased conductive the corresponding shunt diode e.g. D1 is biased non-conductive, while the other series diodes, e.g. D2-D6 are biased non- conductive and the corresponding shunt diodes, e.g. D12-D16 are biased conductive.
