Title: Improvements in bottle collaring machine
IPC: B65C3/18
Filed: 1934-07-09
Abstract: 422,329. Labelling-machines; feeding- devices. DEHN, F. B., 103, Kingsway, London.-(Pevely Dairy Co. ; 1001, South Grand Boulevard, St. Louis, Missouri, U.S.A.) July 9, 1934, No. 20136. [Class 73] [See also Group II] A machine for placing conical advertising collars on the necks of bottles comprises a turret on which are mounted collar magazines and means for taking collars from the magazines in turn and dropping them on to bottles fed by a conveyer. The magazines 32, Fig. 2 are mounted radially on a tubular shaft 21 rotated by bevel gearing 20 from a horizontal shaft 18 driven, through a clutch, from a motor. The collars are supported by U-shaped tubular members 34 and are retained by wedges 55. The collars are removed by fingers carried by spring-influenced rods 23 which are reciprocated as the shaft 21 rotates by means of a fixed cam 25. Each rod 23 is provided with a rack 28 engaging a segment carried by a pivoted arm 36, Fig. 9 the end 49 of which forms a collar-gripping member. Another gripping member is formed by the end of a cranked lever 42 influenced by a spring plunger 47 and operated by a link 41 connected with a plate 38 pivoted at 39 and fitted with a roller 40 riding on a freely-mounted and angular cam member 37. As the rods 23 reciprocate, the levers 42 and 36 remove a collar and release it when in position above a bottle neck. Each magazine is furnished with duplicate sets of levers 36, 42, and the lower lip of the magazine is fitted with a friction member 57 secured thereto by a screw 58. The bottles are fed by a conveyer 60, Fig. 1 and engage a trip lever 65 operating a catch engaging a latch 87 on the end of a lever carried on a shaft 72 and connected by a link 77 to a clutch controlling shaft 79. The shaft 72 is rocked, in step with the rotation of the shaft 21, by means of an arm thereon engaging a cam 74, Fig. 2 on the bevel 20, and, when a bottle is not present, is engaged by the catch operated by the trip lever 65 to hold the clutch in inoperative position. The clutch comprises a dog 83, Fig. 5 mounted in a recess 82 in the driven shaft 18 and pressed by a pin 85 into engagement with one of a number of notches 86 in a driving collar. The pin is thrown into its disengaged position by a member 80 on the shaft 79 operated by the member 77. The bottles then pass a retarding arm which is operated by a cam on the shaft 21 to release the bottles in step with the operation of the collar-feeding mechanism.

Abstract: 981,752. Protective arrangements. ENGLISH ELECTRIC CO. Ltd. June 7, 1961 [June 9, 1960], No. 20256/60. Heading H2K. [Also in Division H3] A protective arrangement has timing means comprising a capacitor 12 arranged to be charged by a unidirectional overcurrent or overvoltage operating signal, non-linear resistor means connected in parallel with the capacitor to retard its charging when the signal is relatively high, and non-linear resistor means connected in series with the capacitor to retard its charging when the signal is relatively low. In Fig. 1 the parallel-connected non-linear resistor means comprise rectifiers 4, 5 in series with resistors 18, 29 and the series-connected non-linear resistor means comprise rectifiers 6 and resistors 32, 33, though in Fig. 2 (not shown) the rectifiers may be replaced by voltage-dependent resistors. In each case the capacitor 12 may be shunted by a normally-conducting transistor T1 which is rendered non- conducting when the signal reaches a predetermined magnitude. The timing means may be connected to a transistorized measuring and tripping circuit such as that of Specification 958,774. It is stated that the provision of the non-linear resistor means results in a relay characteristic curve which corresponds with that of British Standard Specification No. 142.

Title: Improvements in or relating to load supporting devices
IPC: F16F15/067
Filed: 1954-07-12
Abstract: 769,578. Spring supports. AITON & CO., Ltd., CHAMBERLAIN, J., and HILL, G. A. H. May 23, 1955 [July 12, 1954], No. 20346/54. Class 108(3). The invention relates to a load supporting device in which the load is suspended from the pivotal junction point 6 of two spring-loaded arms 2, 2<SP>1</SP>, forming the sides of two opposed and balanced triangles of forces and pivotally mounted at their respective ends opposite to the point 6. According to the invention, each of the arms 2, 2<SP>1</SP> is held under compression by an adjustable device so arranged that its position may be varied after the arms 2, 2<SP>1</SP>, have been assembled. Each arm 2, 2<SP>1</SP>, comprises a tube 10 slidable within a tube 16 having threaded engagement with a ring 4 trunnionmounted at 17. A bearing 22 permits rotation of the sleeve 16 by means of a key 23 to adjust the force of the load supporting spring 11. The degree of adjustment is indicated by the position of an indicator plate 30 carried by the bearing 22, relative to a scale behind a slot 29 formed in the frame 1 of the supporting device. A stop plate 28 limits the collapsing movement of the tube 10 in the event of fracture of the spring 11. The plate 28 is in threaded engagement with the bore of the sleeve 16 and its position may be adjusted by means of a key 27.
Patent GB-148408-A (GB)
Title: A process for the preparation of ar tetrahydro-ª -naphthol
IPC: C07C35/36
Filed: 1920-07-10
Abstract: Sulphonation of tetrahydronaphthalene with sulphonic acid produces tetrahydronaphthalene-b -sulphonic acid; fusion of this acid or its alkali salts with caustic alkalis, with or without milk of lime, gives tetrahydro-b -naphthol.  Heating a solution of the tetrahydro-b -naphthol in sulphuric acid gives its a -sulphonic acid which on nitration gives a dinitrotetrahydronaphthol.  Treatment of tetrahydronaphthalene with chlorsulphonic acid gives a mixture of tetrahydronaphthalene -a - and -b -sulphochloride; this mixture, on hydrolysis by alkalis, gives alkali-salts which yield tetrahydro-b -naphthol by alkali fusion.  The Specification as open to inspection under Sect. 91 (3) (a) states that the sulphochloride may also be obtained by chlorinating the sulphonic acid.  The sulphochloride on reduction, e.g. by means of zinc and acid or by electrolysis, gives tetrahydro-b -thionaphthol; this body gives a methyl ether on treatment with dimethyl sulphate and a thioglycollic acid by reaction with chloracetic acid; air-oxidation of its ammoniacal alcoholic solution gives the corresponding disulphide.  This subject-matter does not appear in the Specification as accepted.

Abstract: 442,862. Variable - speed gearing. TRIGGS, W. W., 57, Lincoln's Inn Fields, London.-(Lover, F. R. Banning-; Minerva House, Colpetty, Colombo) July 17, 1934, No. 20929. [Class 80 (ii)] An automatic variable-speed gear or torque converter comprises a driving-disc 31, Fig. 2, which carries weighted levers 35 each connected by a separate link 42 to a crank 34 on a driven shaft 4, Fig. 3, coaxial with the disc. Each lever supports an inertia mass 40 and is in turn supported on a pivot 39 fixed in the disc 31. As the disc turns relatively to the crank 34, the masses 40 are oscillated and their resistance produces a torque on the crank 34 and shaft 4 tending to reduce the relative motion and so drive the shaft 4 at the same speed as the disc. In Fig. 3, there are rigid with the same driven shaft 4 two cranks 34, 34<1> in two bays A and B between three driving discs 30, 31, 32. In the bay B is a duplicate set of weighted levers 35. Arrangements are described with the weighted levers arranged in pairs. In a form shown in Fig. 8, the weighted levers are cylindrical masses 76 rockable on eccentric pivots 72 carried by the driving-disc 71. A separate link 80 is journalled around each mass 76 and also upon the driven crank pin 70. Forms are described in which the oscillated weights are formed with toothed rims which serve to oscillate smaller satellite masses at a higher speed. A lay-out for driving a vehicle is described with two such torque converters for driving separately the parts of the differential axle to replace the usual change-speed gearing and differential. The Provisional Specification describes an arrangement in which a shaped inertia mass is carried round over an eccentric loose on the driven crank pin.
