Title: Manufacture of carboxylic and sulphonic acid chlorides
IPC: C07C63/00
Filed: 1973-08-17
Abstract: 1434400 Preparation of carboxylic and sulphonic acid chlorides HOECHST AG 17 Aug 1973 [19 Aug 1972] 38967/73 Heading C2C Carboxylic or sulphonic acid chlorides are prepared by reacting a carboxylic or sulphonic acid and a nitrogen-containing compound, which is an N,N-dialkyl carboxylic amide having at least 4 carbon atoms, an N-alkyl pyrrolidone, or tetramethylurea, in an inert polar watermiscible solvent or diluent, with phosgene, at a temperature of less than 0‹ C. The acid and the nitrogen-containing compound may be used in the form of their salt-like addition compound, and the reaction temperature, which is preferably from -20‹ to 0‹ C., may be allowed to rise to not more than 30‹ C. after the reaction is substantially complete. If the reaction is conducted under an elevated pressure, the latter may be reduced after the reaction is substantially complete, and an excess of the nitrogen-containing compound may be employed as the solvent. The starting materials may be aliphatic, cycloaliphatic, aromatic or heterocyclic mono- or poly-carboxylic or sulphonic acids, many of which are specified. The products may be used directly for a subsequent reaction, e.g. in the preparation of ester or amides, without further treatment or purification.

Savings' boxes; coin action, weight.-A savings' clock has a two armed lever 15, 16 frictionally held by a spring on the winding axle 13, so that, when the clock is wound, the lever is rocked thereby causing a resilient pin 20 on the arm 15 to engage the balance wheel 21 to stop the clock and the arm 16 to project through slots 22 into a coin shoot 23. A coin inserted through a. slot 24 hits the arm 16 and rocks the lever back to start the clock. An arm 26 of a spring-controlled locking pawl 26, 27 engages under a lateral extension 25 of the arm 16 to prevent the lever 15; 16 from being released by shaking the clock or by a blow. The arm 27 enters the coin shoot above the arm 16 so that the coin first disengages the locking pawl before actuating the lever 15, 16. Fraud, preventing; coin-slit closing-devices.- In order to prevent the lever 15, 16 from being actuated by the insertion of a long thin article, the coin slot is normally covered by the arm 2S of a two armed lever 28, 29. A coin during insertion acts on a bevelled edge of the arm 28 to move this aside against the action of a spring 31, and cause the, arm 29 to engage the extension 25, so that the lever 15, 16 is locked when the coin slot is uncovered.

There may be such means for a price indicator and for a volume indicator. The volume indicator is directly driven by the pulses, whereas the price indicator may be driven through change-speed gearing. Each fluid pulse may release one pawl in a set to allow movement in steps, the next pulse releasing the next pawl, and so on. The starting and stopping of the pump may be controlled by fluid-pressure means. An interlock system may be provided whereby dispensing is not possible unless the grade of petrol indicated by a movable bond is the same as that represented by the setting of the change-speed gearing, and the meters are zeroized. The means for controlling starting and stopping of the pump and the interlock system form the subject of Specification 1268489.

Abstract: 859,327. Making bearings and cams. MAYBACH - MOTORENBAU G.m.b.H. Dec. 10, 1958 [Dec. 12, 1957], No. 39896/58. Class 83 (2). [Also in Groups XXIV and XXXIV] A wearing surface on a shaft, e.g. a cam face or a journal bearing surface, is produced by shaping the member from a non-hardenable basic material, such as austenitic steel, forming a groove or fillet in the raised working surface with its boundaries left intact, filling the groove or fillet with wear-resistant material as by built-up welding or spraying, and then grinding down to the lateral boundaries, this method avoiding clogging of the grinding wheel by the softer basic material. In the case of a cam, Fig. 1, an arcuate fillet 13 is formed in the working surface with the lateral portions 14 intact, while in the case of a journal bearing, Fig. 5, a shallow groove with a roughened base portion 18 and undercut sides 19 is formed for the reception of the wear-resistant material.

Title: Apparatus for supplying objects to be bound to an automatic band-binding means
IPC: B65B13/18
Filed: 1975-09-30
Abstract: 1513475 Conveying objects to a banding machine S MAE & M UMEZU 30 Sept 1975 [4 Dec 1974] 39905/75 Headings B8A and B8C A pusher 22 driven by a connection 23 to a driving belt 27, engages the rear face of an object (not shown) which is to be tied with a band under a banding arch (17) (Figs. 1 and 2, not shown), the pusher being stopped automatically at three separate binding positions corresponding to the length of the object. The pusher carries a switch-operating member 30 on an arm 29 (rigid with a slider 21 carrying the pusher). The member 30 first engages a switch S5 causing the ram to stop while the first band is tied. At the end of this tying operation, the pusher is restarted, and is stopped again for the second tie, when the member 30 engages a switch S6. The final tie is carried out when the member engages switch S7. The switches S5, S6, and S7 are driven along their mounting on a slideway 41 while the object is being conveyed into position by feed-in belts 3, 3, by respective belts 57, 58 and 59. These belts have a common drive shaft 51 but the drive pulleys have different respective diameters. In this way the stopping positions for the object beneath the banding arch (17) are adjusted in relation to the length of the object in the conveying direction. The movement of the switches ceases when the leading edge of the object operates a switch S3, thus in effect (with the operation of the pusher mechanism so far) measuring the length of the object. The head (35) of the pusher (Figs. 7 and 8, not shown) is spring urged upwardly to a position above the surface on which the object is conveyed. Before it commences its travel however, it is held in a retracted position below the surface (full line position, Fig. 8, not shown).

Title: Transistor oscillator
IPC: H03K3/354
Filed: 1972-08-31
Abstract: 1341797 Transistor variable frequency oscillators RCA CORPORATION 31 Aug 1972 [7 Sept 1971] 40341/72 Headings H3T and H4L A relaxation oscillator has a capacitor 135 alternately charged by invertors 121, 121<SP>1</SP> under the control of a bi-stable 140, itself triggered by the voltage on the capacitor. Complementary FET's constitute the invertors, and are also used in the bi-stable Fig. 5 and in the invertors 146-149, 151-154 which drive it. The positive supply current at 119 is variable by Vin at 101 to vary the output frequency at 156. Supposing the output Vco to be low and the other output 143 therefore high, then p-channel FET 123<SP>1</SP> and n-channel FET 124 will be on, and 123, 124<SP>1</SP> off. Plate 134 of C135 is therefore earthed, and plate 134<SP>1</SP> is charged positively towards Vdd. When it reaches the threshold of invertor 151, the bi-stable is triggered to its other state, and the outputs 143, 144 turn off FET's 123<SP>1</SP>, 124 and turn on FET's 123, 124<SP>1</SP>. Plate 134<SP>1</SP> of C135 is therefore earthed through FET 124<SP>1</SP>, and plate 134 is carried negative, which causes the drain-substrate function diode of FET 124 to conduct, thus discharging the negative level to earth. FET 125 now charges the plate 134 towards Vdd, until invertor 146 conducts to change the bi-stable state again. The invertors 146-149 and 151-154 provide a delay to ensure complete switching of the bistable before the capacitor 135 is discharged each half-cycle. AND gate 150 ensures that the oscillator starts when the supply is turned on, by preventing the NOR gates 145, 155 from receiving simultaneous 1 inputs. The variable input voltage Vin controls the current in FET 103, and hence the voltage across a FET 110 having its gate and drain connected. This latter voltage controls a matched FET 115 supplying the resultant variable current at 119, and hence varies the output frequency. The bi-stable Fig. 5 has each of the crosscoupled NOR gates 145 (155) formed by a series pair of FET's 203, 205 (203<SP>1</SP>, 205<SP>1</SP>) feeding the output 156 (143) and receiving respectively the two inputs A, B, (C, D) and also a parallel pair of FET's 204, 206 (204<SP>1</SP>, 206<SP>1</SP>) likewise feeding the output and receiving the respective inputs A, B (C, D). The AND gate 150 is incorporated in one of the NOR gates 155<SP>1</SP>, and involves the addition of two FET's 207, 208 receiving the further input C, one 207 being in parallel with one of the series FET's 203<SP>1</SP>, and the other 208 in series with one of the parallel FET's 206<SP>1</SP>. Two inputs C, D are thus ANDed at the input of one NOR gate 155<SP>1</SP>.
