Patent GB-629090-A (GB)
Abstract: 629,090. Autographic registers. MOSELEY, N. S., and SPENCER, F. E. April 30, 1946, No. 12931. [Class 106 (i)] An autographic cash till comprises a cash drawer mounted slidably in a body, a flexible recording strip carried in said body, a window in said body, and means for automatically advancing the strip past the window. The drawer is spring-urged to the open position and the body is provided with a releasable catch-mechanism for releasing the drawer in the closed position, situated at the front and to one side of the cash drawer. The cash drawer 13, Fig. 2, carries at its rear end a coiled spring which when the drawer is closed is compressed against the backplate of the body, the drawer being retained closed by a catch-mechanism, including a spring-pressed pivoted lever 59, Fig. 5, the outer end of which projects through the front of the body and carries a key-button 61, At its inner end the lever 59 engages a vertical rod 63 the lower end of which normally engages a recess 64 in the adjacent flange of the drawer 13. Upon depression of the button 61 the lever 59 lifts the rod 63 out of the recess 64 and the drawer 13 is pushed outwardly by the spring 9. A latch 71 pivoted to a plate 50 may be manually rocked anticlockwise, Fig. 5, to prevent vertical disengaging movement of the rod 63 when desired. At the beginning of outward movement of the drawer 13 a locking bolt 36 at the rear thereof strikes a bell 37 carried by the body. At the end of the outward movement the bolt 36 engages a flange 46 on the front of the body to prevent complete ejection of the drawer. If it is desired to remove the drawer 13 the pin 44, Fig. 2, is removed rearwardly out of engagement with the bolt 36, which then falls down below the level of the flange 46. During the outward movement of the drawer 13 a pawl 32 mounted on one side of the drawer engages a toothed wheel 31 carried by a spool 25 and so rotates said spool one tooth pitch to wind a paper strip 23 from a drum 53 on to the spool 25. The strip 23 passes over a plate 24 which is situated under an open window 19 on the lid 11 so enabling the operator to write on the paper strip. The spool 25 has at each end bearing spigots which are mounted releasably and rotatably in guides on opposite sides of the body, a plate spring retaining the spool in position. Rollers 66 on the sides of the body engage the flanges of the drawer 13 during its sliding movement. The body and drawer are made from sheet metal.

Abstract: 722,795. Hydroxyaminobenzoic acid esters. RHEINPREUSSEN AKT.-GES. FUR BERGBAU UND CHEMIE, [formerly STEINKOHLENBERGWERK RHEINPREUSSEN]. Oct. 23, 1950 [Oct. 22, 1949; July 31, 1950], No. 25817/50. Class 2 (3).  The invention comprises esters of hydroxyaminobenzoic acids in which the alcohol residue has the general formula -R.NR 1 R 2 , where R is a saturated aliphatic hydrocarbon radical containing not more than 6 carbon atoms, one of R 1  and R 2  is hydrogen and the other an alkyl, aryl, aralkyl or alkaryl radical containing not more than 8 carbon atoms, or R 1  and R 2  are each an alkyl, aryl, aralkyl or alkaryl radical containing not more than 8 carbon atoms, or -NR 1 R 2  is a nitrogen-containing heterocyclic ring; but excluding the dimethylamino-, diethylamino-, dipropylamino- and piperidinoethyl esters of 2-hydroxy-4-aminobenzoic acid. The esters may be prepared by esterification of the acid with the amino alcohol in the presence of a concentrated inorganic or an aryl sulphonic acid, the amount used being sufficient to prevent undue decomposition of the hydroxy aminobenzoic acid. Alternatively, the amino alcohol may be replaced by a halogenated alcohol and the halogen-containing ester subsequently reacted with a primary or secondary amine. In other processes, a salt of a hydroxyaminobenzoic acid is reacted with a halogenated amine, and an alkyl ester of the hydroxyaminobenzoic acid is reacted with an N-substituted aminoalcohol in an ester-exchange process. In examples, (1) 2-hydroxy-3-aminobenzoic acid is esterified by means of #-diethylaminoethanol in the presence of substantial amounts of concentrated sulphuric acid; (2) 2-hydroxy-3- aminobenzoic acid is similarly esterified with ethylene chlorohydrin and the #-chloroethyl ester formed heated with diethylamine in benzene under pressure; and (3) 2-hydroxy-5- aminobenzoic acid is reacted with 1-chloro-2- diethylaminoethane in the presence of sodium and isopropanol. Specifications 588,032, 722,885 and 722,886 are referred to.
Patent GB-2003332-A (GB)
Title: An insulating housing for junction blocks
IPC: H01R9/26
Filed: 1978-07-03
Abstract: Connection strips are made up of a stack of insulating housings (5) for junction blocks. The housings are assembled side-by-side and each includes a recess in one of its side faces (3) to receive an insulating separator (6) which is inserted between an assembled pair of adjacent housings to increase the length of the leakage path between the live parts in the adjacent housings. Play, resilience and flexibility are needed to make it possible to insert the insulating separators (6) after a connection strip has been assembled, and this has the result that they tend to come out again under, for example, conditions of severe vibration. In the present invention there are separator- engaging lugs (32, 42) which project into each recess from both housings adjacent to the recess and engage holes in the separator. Thus any force tending to release the separator from the lugs of one housing tends to lock the separator against the lugs of the opposite housing and vice versa. <IMAGE>
