Filed: 1931-12-16
Abstract: 378,751. Smallarms. RHEINISCHE METALLWAARENUND MASCHINENFABRIK, 195, Ulmenstrasse, Derendorf, Dusseldorf, Germany. Dec. 16, 1931, No. 34880. Convention date, Sept. 11. [Class 119.] Relates to smallarms having a longitudinally moving breech-bolt, and a safety device mounted in the bolt adapted to engage with and lock the firing-pin. According to the invention, the safety catch i, Figs. 1 and 3, has a hand-grip i<1> which is so shaped and disposed that it can nest completely within the breech-bolt b. In the form shown, the barrel c recoils with the bolt b when the gun is fired. The firing-pin e is guided by telescopicallymounted members f<1>, f<2>, f<3>, which are surrounded by the firing-pin spring f, which also acts as a brake for the recoil of the barrel. The safety catch i is pivoted on a pin b<2> in a transverse slot b<1> in the bolt b. When the hand-grip i<1> is withdrawn from the slot b<1>, a shoulder i<2> of the catch enters one of two slots e<1>, e<2> in the firing-pin and holds the latter against movement in either the stressed or de-stressed position. At the same time, the hand-grip engages with a shoulder a<1> of the breech casing a and thereby prevents the bolt from being retracted. In a modification, the slots e<1>, e<2> are replaced by an upper ledge on the firing-pin, which ledge also constitutes a guide for the pin. A lever g pivoted to the firing-pin is connected to the trigger mechanism and is adapted to hold the firing-pin in the stressed position until the trigger is pulled.

[Class 106 (i).] Multiplying and dividing apparatus.-In a machine for the four rules having a product register and a grand total register means are provided for converting the terminal fractional value in the product register to the nearest whole number when transferring the amount to the grand total register. The invention is shown applied to a machine of the type described in Specifications 229,642 and 304,121, [both in Class 106 (i). Calculating &c.]. In Specification 304,121 is described an arrangement whereby the amount standing on a product register can be transferred to a grand total register by zeroizing the product register. In accordance with the present invention the grand total register 33 is displaced to the left with respect to the product register by three denominations as shown in Fig. 3 for the purpose of effecting an approximation in the result transferred. The units numeral wheel 33a, Figs. 1 and 3, is provided with a transfer lever 64a having a depending projection 128 adapted to co-operate with a cam disc 125 associated with the numeral wheel 5a of the highest discarded denomination of the product register. The cam 125 is provided with two surfaces 126, 127 corresponding to the digits 5 .. 9 and 0 . . 4 respectively. When the grand total register is lowered into engagement with the intermediate pinions 4 as described in Specification 304,121 the projection 128 moves into contact with one or other of the surfaces. If the surface 128 is engaged the transfer lever 64a will be rocked to raise its shoe 67 into the path of a pin 75 on a lever 72 pivoted on a recessed disc 71 carried by the shaft 34. As the shaft rotates the pin 75 rocks the lever 72 so as to cause a second pin 76 on the lever to engage the teeth 35 of the units pinion 33a and advance it one step. The machine is driven by an electric motor the application of power being controlled by a clutch 105 through the medium of a lever 114 and key 116, Fig. 9.

Filed: 1969-07-15
Abstract: 1281601 Flat glass manufacture GLAVERBEL 15 July 1969 [24 July 1968] 35640/69 Heading C1M In a method of manufacturing flat glass using the " float " glass process, a portion of the protective atmosphere is withdrawn from above the surface of the molten material at one zone in the tank, purified by passing at least a portion of the withdrawn gas through caustic soda or limonite, and then reintroducing the gas thus treated into the tank at another zone. The gas may also be cooled outside the tank to condense impurities from the gas. Preferably, the gas is withdrawn from a zone in the hotter end of the tank and reintroduced into the tank in a cooler zone thereof. The gases withdrawn from the tank are passed through a cooling chamber 73 and as a result condensable impurities such as SnS are collected in a funnel 77. The gases then pass through a filter 86 to an absorber chamber containing the caustic soda or limonite to absorb non-condensable impurities such as H 2 S. Finally, the gases pass through a deoxygenating device 101 within which oxygen is reacted wth the hydrogen in the gas stream in the presence of palladium mounted on an alumina support.
