IPC: G01L7/00
Filed: 1943-11-10
Abstract: 601,589. Indicating-apparatus; gauges. WALLACE & TIERNAN PRODUCTS, Inc. Nov. 10, 1943, No. 18682. Convention date, Sept. 24, 1941. [Classes 106 (ii) and 106 (iv)] This invention relates to apparatus for translating small displacements of sensitive precision instruments into enlarged movements of an indicating device such as a pointer for use in aneroid barometers, altimeters and similar instruments. As shown in Fig. 1, a bellows 20 of an aneroid barometer carries a post 21 and is centrally mounted at 22 to the inside of one arm of a U-shaped supporting member 23, the other arm 24 of which extends to a position close to the post 21 and has a lug 25 mounted on a vertical post 26, Fig. 4. The member 23 has an extension 30 which is held by a coil spring 32 against an adjusting screw 31 and which is guided between a pair of vertically spaced pins 38 extending from a block 34 on the screw 31. A lever 45 is attached to the post 21 and the member 23 by two flexible U-shaped strips 47, 48 and 49, 50, Fig. 4. The lever 45 is balanced at one end by a member 54 and at its other end is bifurcated into two arms 55, 56, Fig. 5, between which is stretched a thin wire 58. A member 85 connects the wire 58 to the offset centre part 73 of a vertical wire 70, 75 threaded through apertures in the arms 61, 62 of a U-shaped supporting strip 60, 61, 62 and clamped by wires 71, 76. The U-shaped strip carries a rod 63 bent at right angles to have a horizontal portion 64 terminating in a pointer 65 which moves over a scale 67. The arms 61, 62 carry a pair of damping vanes 81, 81 arranged to swing in a box 82. In another embodiment, Fig. 6, the pointer-supporting frame comprises a strip of metal having a rearwardly extending loop 90 and a forwardly extending loop 91 which carries a pointer rod 92, 94. The frame is mounted on a vertical shaft 97 freely rotatable in bearings 98, 99. The embodiment shown in Fig. 7 is similar to that of Fig. 1, but the shaft 197 which carries the pointer-supporting frame is provided with a small drum 205, Fig. 11, fixed to and round which is partially wound a wire 206 fastened to the outer end of the resiliently supported lever 145. Another wire also fastened to the drum 205 extends round it in the opposite direction and is secured to one end of a long coil spring 208, the other end of which is secured to an arm 215 of a U-shaped spring strip. The tension of the spring 208 may be varied by turning a cam 218 which abuts the arm 215. When the lever 145 is displaced in one direction, the wire 206 rotates the drum 205 so displacing the pointer 164 and when the lever 145 is displaced in the other direction the spring 208 reverses the.rotation of the drum 205 and consequently the pointer 164 moves in the opposite direction.

Patent GB-190159-A (GB)
Abstract: 190,159. Krupp Akt.-Ges., F. Dec. 9, 1921, [Convention date]. Void [Published under Sect. 91 of the Act]. Cash registers with several item-value totalizers. -In a machine adapted to print and accumulate the items of a large number of accounts, a series of totalizers corresponding with the highest denomination digits of the accountcharacterizing numbers is employed for the purpose of separately accumulating the amounts in each group of accounts during the day. Thus in the case of account numbers running up to 100,000 ten totalizers are provided for registering the items received under account numbers 1-9,999, 10,000-19,999 &c. respectively. The machine described has five banks of amount keys and five banks of numeral keys for setting up the account numbers. The highest of the latter banks, namely C', controls the differential positioning of a disc F' and thus through gearing f<13>, g<2> correspondingly rotates a disc G, Fig. 7, to bring a radially slidable block G<3> alongside a roller d<3> mounted on a pivotal frame d<1>, Fig. 3, carrying the totalizer D concerned. In the operation of the machine, a cam disc H is rotated to slide the block inwardly and so engage the selected totalizer with the gear wheels B<1> which are subsequently differentially actuated under the control of the amount keys. The differential movements are determined by the keys through the tripping of bolts such as f<9> when latches f<10> meet the depressed key stem the driver F<6> thus being disengaged from the inner end of the bolt at f<8>. For account numbers up to 10,000 no key C<1> is depressed and consequently means are provided to disconnect the driver from the differential disc F' when this is in the lowest or zero position. For this purpose, a spring-controlled lever J having two ears i<1>, i<2> and controlled by the keyrelease shaft K is so placed when no key has been depressed that the ear i<1> is to the front of the key detent plate C<4> and the ear i<2> lies in the path of a pin f<19> on the bolt. In the subsequent downward and upward excursion of the driver F<6> therefore, the bolt is unlatched when in its lowest position which corresponds with the engagement of the first totalizer D'. If a key is depressed, the detent plate C<4> effects the release of the lever J so that the ear i<2> does not function When it is desired to enter items in the machine, without registration, a lever C<5> must first be raised so as to release the lever J to render it ineffective, the driver and disc F' then moving together throughout the excursion and the grooved disc G returning to the position shown in Fig. 7 wherein the block G<3> has no influence on the totalizer frames.

Patent GB-646976-A (GB)
Title: Improvements in or relating to production of dimethylamine
Filed: 1948-07-19
Abstract: Dimethylamine is produced by treating tetramethyl methylene diamine [(CH3)2N]2CH2\t with hot aqueous alkaline hydroxide solution having a concentration between 2 and 16 per cent.  Tri-ethylamine is produced by a side reaction.  The reactants may be refluxed together, optionally in the presence of cuprous oxide, cupric oxide, iron oxide and nickel powder which accelerate both reactions but the side reaction to a proportionately greater extent.  To reduce trimethylamine formation the alkaline hydroxide should be in excess. This may be secured by heating sufficiently to ensure that all the tetramethyl methylene diamine is in the vapour phase. Semi-continuous operation is preferred in which tetra-methyl methylene diamine is vaporized and passed into the hot aqueous alkaline hydroxide solution in the absence of a catalyst.  The vaporous products are passed to a condenser when water, methanol and unreacted tetramethyl methylene diamine are condensed and recycled and di-and tri-methylamines remain as vapours which are separated by fractional condensation.  Methanol accumulating in the residue is removed by adding solid caustic soda.  Tetramethyl methylene diamine may be prepared by reacting dimethylamine and formaldehyde or in a crude amine mixture by reacting formaldehyde and an ammonium salt. In examples: (1) Volatilized tetramethyl methylene diamine is bubbled through heated caustic soda solution containing cupric oxide; (2) a process similar to (1) is carried out but in the absence of a catalyst (3); and (4) a product obtained by reacting formaldehyde and ammonium sulphate and containing tetramethyl methylene diamine, dimethylamine and trimethylamine is treated as in (2); (5) tetramethyl methylene diamine is heated with caustic soda solution under reflux at raised pressure.  Both dimethylamine and trimethylamine are produced simultaneously in all examples with the exception of (3) when dimethylamine only is produced.
