Filed: 1935-04-01
Abstract: 459,127. Latches. HARRISON, F. A., 2, Bromley Road, Wallasey, Cheshire. April 1, 1935, No. 10071. [Class 44] A latch or bolt, particularly for use on motor cars, is withdrawn by pushing in a panel which is normally flush with the surrounding surface. A panel 1 backed by a plate 2 normally fits snugly within an aperture 3<a> in the door panel and is supported by sleeves 2<a> sliding upon fixed pins 7. A cam surface 4<a> on the plate 2 engages a cam surface 5a on a spring latch 5, so that pressure on the panel 1 retracts the bolt. The edge of the aperture 3<a> serves as a hand grip and may be provided with a ledge for this purpose beneath its lower edge. Fig. 5 shows a modification in which a stamped panel 1 pivoted at its upper edge has a cam 4 engaging the bolt 5. Pins 13 carried by brackets on the panel engage bellcrank levers 14, 15 connected by a bar 16 which serves as a handle when the panel is depressed. The bar 16 normally lies below the opening. A panel mounted similarly to that shown in Fig. 2 may have a cam slot for raising two vertically sliding brackets carrying a bar to serve as a handle. Fig. 10 shows a fixed handle 24 of D-section which normally lies flush within a recess in the panel 1. Roller guides may be provided at the edges of the panels. An operating panel also is described mounted on a tube of approximately the same diameter which slides over a fixed tube, both tubes being slotted to permit the passage of the bolt. The latch may be operated from inside the door by the usual lever or a second panel operating independently of the outside panel may be used. For locking the panel to prevent unauthorized use, a pair of bolts 31, Fig. 15, normally retracted by springs 35, are shot by a key-operated cam 33.

Abstract: 627,642. Glass furnaces ; charging. UNION DES VERRERIES MECANIQUES BELGES SOC. ANON. April 18, 1947, No. 10346. Convention date, June 22, 1946. [Class 51 (ii)] A tank furnace for glass manufacture is charged by depositing a thin layer of batch material on the surface of the molten glass in an extended part of the tank and propelling it forward at an approximately uniform speed by means of a continuously moving member. In one form, Figs. 1 and 2, hoppers 13 and 14 are arranged to deposit superposed layers of batch material on the surface of the molten glass in an extension 6 of the tank 7, and the material is propelled into the furnace by an endless band feeder 1 positioned so that its lower periphery, is in contact with the material. The feeder consists of articulated metal strips passing over rollers 2, 3 mounted in bearings 10, 11 and is driven by speed reduction gearing 4 coupled to the roller 2 by a power-limiting clutch 5. The strips may be formed with projections such as bars 9 which penetrate the layer of material and engage the molten glass surface so that the upper layer of molten glass is also set in motion. The height of the feeder may be adjusted by means of screws 19 and the rollers may be tilted so that the material is fed to either side of the tank. The speed of the feeder may be controlled automatically by a level indicator in the tank. In a second form, Fig. 3, the endless band is replaced by a roller 2 formed with projections 9 and arranged beneath a hopper 13 with its surface in contact with the layer of material. The charged material passes beneath an adjustable refractory partition 8 which prevents escape of the furnace atmosphere.

Abstract: 1409042 Impact absorbing device SIEMENS AG 7 March 1974 [19 April 1973] 10370/74 Heading F2E [Also in Division B3] A damping device for use especially in a nuclear power plant installation for absorbing impact forces by first yielding elastically and then undergoing plastic deformation comprises a rectangular plate-like support 14 which presents an impact absorbing surface 16 and which has at least its rims 18, 19 unrestrained, and an impact receiving member in the form of a blade 17 engaging the impact absorbing surface 16 and arranged to transmit impact forces received by the damping device to the support 14, the blade 17 being made of a harder material than the material of which at least an upper support portion of the support 14 is made. Thus the blade 17 may be made of steel or hardened steel and the support 14 may be made largely of aluminium although its base 15 may be made of steel.  The blade 17 may extend laterally beyond rims 18, 19. The support 14 is advantageously pre-pressed in a localized region prior to engagement by blade 17. This may be effected by utilizing a pressure blade (not shown) to form an impression in the support 14 about 3 mm. deep and subsequently planing the support 14 to a flat surface by about 5 mm. Figs. 1, 2 (not shown) illustrate the damping device as a bearing (7 or 11) for absorbing the impact of a steam generator (1) of a nuclear power station having a pressure water reactor, which impact results from the rupture of a steam pipe (3) (Fig. 1) or of a primary coolant pipe (Fig. 2).

Filed: 1924-04-28
Abstract: 231,338. Clauss, M. O. April 28, 1924. Paper tubes. - Tubular bands of paper are formed from blanks removed from a magazine by a device which also acts as a mandrel around which the blank is pressed by a recess in a die by relative movement between the die and mandrel, the die afterwards serving as a stripper. The sheets 9 are placed in a magazine 8 and are pressed forward against a guard-plate by a spring- actuated pivoted lever 12 under a constantly decreasing pressure. The mandrel 32 which acts by suction is hollow, being connected through a bead 27 with a suction tube, and is carried so as to lie in front of the magazine by a reciprocating bar 22 actuated by a cam 18 on the main actuating-shaft 17. A pasting-box 39 and bending-roller 41 are carried at the extremities of levers 38, 40 respectively actuated by cams 43 on the main shaft, and a reciprocating stripper 61 which also acts as a former is operated by a lever 59, rock shaft 49 and cam 57. The sequence of operation is as follows. The mandrel 32 is advanced to press against the first blank in the magazine and is then retracted with the blank adhering due to suction. The stripper and former 61 is then advanced across the front of the magazine and when at rest the mandrel 32 is again advanced carrying the middle of the blank into a recess 63 in the former to rest against a spring pressed rubber-covered strip 64 in the former, thus bending the free edges of the strip at right-angles, Fig. 1. The lever 38 is then oscillated whereupon a pasting-roller on the tank 39 pastes the upper edge and at the same time bends it downward around the mandrel. The lever 38 is then retracted and a lower spring- mounted bending-roller on the lever 40 comes into operation to bend the lower edge over the pasted edge and thus complete the tube. The former 61 is then retracted from the mandrel endways, the spring presser bar 64 stripping the tube from the mandrel. All the operations are effected from a single cam shaft.
