Title: Conveyor and Apparatus for Automatically Unloading the Conveyor
Inventor: ROSTRON ROBERT ARNOLD
IPC: B65G47/82
Filed: 1966-02-22
Abstract: 1,188,671. Endless conveyers. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. 4 May, 1967 [22 Feb., 1966], No. 7711/66. Heading B8A. Each of a number of unloading points for carriers of an overhead endless chain conveyer comprises a reciprocable pusher 4 which is selectively operable. The pusher 4 is actuated by a motor 17 via a worm drive 21, 24, a rack and pinion unit 25, 27 and a crank device 19, 20. Rollers 44 reduce friction between the pusher head 7 and the load, and rollers (45), Figs. 4, 5 (not shown), prevent the head 7 from scraping along a carrier platform 3. The carriers are suspended from a rail 1 and comprise a frame 2 from which a flange 3a formed on the platform 3 depends. This flange travels along the rear side of a guide rail 29 which has rollers 30 and is mounted on a stationary framework 8. The rail forms part of a parallel linkage which is spring-urged upwardly, the arrangement allowing for small variations in the level of the carrier as it passes the framework 8. The carrier is also guided by a rail 28. Pusher control.-For initiating the discharge of a carrier a control switch A, B or C at an unloading point is engageable by a member 42 which may be selectively inserted into one of three slots 41 (a, b or c) in a channel-shaped member 41 on the carrier. The switch A, B or C is in a control circuit for the motor 17 and by choice of the slot 41 to receive the member 42, the load of the selected carrier is discharged by the pusher at the chosen unloading point. If the pusher remains in its forward position after pushing the load off a carrier, a wire (47) on the pusher, Figs. 2, 3 (not shown), fouls the carrier and a cut-out is operated to stop the conveyer. The loads are preferably carried on trays or pallets and may be transferred on to auxiliary conveyers provided at each unloading point.

Patent GB-287924-A (GB)
Title: Processes for preparing tetrazoles
IPC: C07D487/04
Filed: 1928-03-16
Abstract: 287,924. Boehringer, A. March 30, 1927, [Convention date]. Addition to 280,529. Tetrazoles are prepared by the action of hydrazoic acid or azides on imido-chlorides, which are produced by the action of inorganic or strong organic acid chlorides on monosubstituted acid amides, in the absence of concentrated mineral acids. When hydrazoic acid is used, it may be added to the acid amide prior to or after the treatment with acid chlorides, whereas azides are added only after the interaction. The reaction takes place with at least one but not exceeding two molecular proportions of the hydrazoic acid or azide, and preferably in the. presence of an organic solvent such as chloroform and of an organic base such as pyridine. According to the examples. alpha-#-cyclopentamethylenetetrazole is obtained when #-leucinelactam is treated first with phosphorus oxychloride with or without pyridine and then with sodium azide, or first with hydrazoic acid and then with phosphorus oxychloride, or first with phosphorus pentachloride and then with hydrazoic acid, or first with pyridine and benzene sulphochloride and then with sodium azide. The acid amides obtained as by-products in the process of the parent Specification may be utilized for the production of tetrazoles. Specifications 250,897 and 285,080 also are referred to. The Specification, as open to inspection under Sect. 91 (3) (a) describes amido-chlorides and the intermediate products in the treatment of oximes with acid chlorides as starting materials; and includes the following examples (1) diphenyltetrazole is obtained bv adding thionyl chloride to benzophenone and hydrazoic acid ; (2) alpha-#-cyclopentamethylenetetrazole is produced by treating cyclohexanonaxime with phosphorus oxychloride in the presence or with subsequent addition of hydrazoic acid; the same product results when cyclohexanonoxime is treated with phosphorus oxychloride and then with sodium azide, or first with hydrazoic acid and then with benzene sulphochloride.

Abstract: 1,133,493. Recovering combustible gas. OSTERREICHISCHE MINERALOLVERWALTUNG A.G. 28 Feb., 1966 [18 March. 1965], No. 8777/66. Heading C5E. Waste gases at low super-atmospheric pressure containing combustible components, e.g. waste gases from oil refineries, are sucked from a waste gas pipe 1 with a suction pressure having a minimum value equal to atmospheric pressure. The suction pressure is preferably maintained 40 to 200 mm. water column above atmospheric. Dangerous leakage of air into the pipe 1 is therefore avoided. A compressor 4 has a by-pass 8 controlled by a pressuresensitive unit 10 connected to atmosphere at 12 and to the suction side 3 of the compressor at 11, and the motor M for the compressor is controlled by switches 15, 16, 18 likewise responsive to the suction pressure. A gauge pressure equal to the water column a is maintained in the pipe 1. The unit 10 may alternatively control the speed of the motor M (Fig. 2) or the capacity of the compressor (Fig. 3), (both Figures not shown).

Title: Electrical timing system

Filed: 1962-03-07
Abstract: 1,003,622. Transistor pulse delaying circuits. RADIO CORPORATION OF AMERICA. March 7, 1962 [March 9, 1961], No. 8858/62. Heading H3T. A system for providing a signal following the last pulse in a train comprises a multivibrator arranged to steer voltage changes due to alternate input pulses to one of two delay circuits, the outputs of which are combined in an OR circuit, the delay circuits imposing delays greater than the inter-pulse interval. As shown, positivegoing input pulses at terminal 10 are steered by circuits 18 to the base of whichever transistor T1 or T2 is conductive. A pulse steered to the base of T1 will cut off that transistor giving a negative-going step at the collector which is fed via circuit 14 to the base of T2 so that that transistor becomes conductive. The negativegoing step at the collector of T1 is passed by capacitor 30 to cut off the NPN transistor T3 for a period determined by the time constant of components 28, 30. A positive pulse is generated at the collector of T3 during this period and is passed via diode 42 to the output terminal 48. The conductive state of the bi-stable circuit 12 is reversed by the next input pulse at terminal 10 giving a negative-going step at point 22 which cuts off T4 for a period determined by the time constant of components 32, 34. This results in a positive pulse which is passed by diode 44 to the output terminal 48. The system thus allows one of the timing circuits 24, 26 to recover while the other is active. In Fig. 2 (not shown) it is, shown that two input pulses fed to terminal 10 separated by a time period less than the delay period of circuits 24, 26 results in a pulse at terminal 48 starting at the leading edge of the first input pulse and ending at a time after the leading edge of the second input pulse equal to the delay introduced by one of circuits 24, 26.
