Title: Improvements relating to spring handles
Inventor: ROWLAND FREDERICK GEORGE
IPC: H01H3/04
Filed: 1959-04-08
Abstract: 881,587. Linkwork. SWITCHGEAR & COWANS Ltd. April 28, 1960 [April 8, 1959], No. 11829/59. Class 80 (3). [Also in Group XXXVII] A handle 7 for operating a rotary member 3 of an electric switch is pivoted at one end 8 in a housing 5 and carries a leaf spring 9 which engages pins 4, 6 on the member 3 and housing 5 respectively. The free end of the spring 9 is stepped and the shorter part bears against the fixed pin 6 and the longer part 10 bears against the pin 4. When the handle is turned, the spring 9 bends until it slips under the fixed pin 6 and, due to the engagement of the part 10 with the pin 4, the subsequent straightening of the spring 9 causes rotation of the disc 3. In a three-position switch, three projections 14, 14a, 14b are provided on a rotary member 13, and two slots 21, 22 are provided in a fixed cover 15 to receive the spring 19 of a handle 17. The projections 14a, 14b are elongated so as to obstruct incorrect insertion of the spring 19 into the slot 21 or 22. For a two-position switch the centre projection 14 may be omitted and the angle between projections 14a and 14b halves.

Title: Improvements relating to the treatment of petroleum hydrocarbons
IPC: C10G69/08
Filed: 1953-04-29
Abstract: <FORM:0748894/IV(a)/1> Petroleum hydrocarbons are treated by passing a petroleum fraction boiling in the gasoline range to a hydroforming stage wherein it is contacted at elevated temperature and pressure in the presence of hydrogen with a dehydrogenation catalyst, passing the whole of the products from the hydroforming stage to a hydrocatalytic desulphurization stage in admixture with a petroleum fraction to be desulphurized which boils above the gasoline boiling range, and fractionating the products from the hydrocatalytic desulphurization stage for the recovery of a hydroformate and a desulphurized petroleum fraction.  The catalyst may be a platinum group metal such as platinum and a halogen such as fluorine.  In a preferred embodiment, a Kuwait naphtha of 100-200 DEG  C. boiling range is passed via line 10 and heater 12 to the platforming reactor 13 where it is treated at 910-930 DEG  F. under a pressure of 700 pounds per sq. inc.  The product is then mixed with a Kuwait gas oil from line 15 and the mixture treated in the hydrocatalytic desulphurization reactor 17 at a temperature of 780 DEG  F. and a pressure of 700 to 500 pounds per sq. inch over a catalyst of cobalt and alumina supported on alumina.  The product leaves the reactor via line 18, heat exchanger 19, cooler 20 and high-pressure separator 21 from which the gaseous fraction passes via hydrogen sulphide removal system 28, compressor 29 and line 30 into admixture with the naphtha feedstock while the liquid product passes via reducing valve 22 and heater 23 to the fractionating column 24 from which desulphurized gas oil is removed via line 27.

Title: Improvements in or relating to High Speed Impact Forming Machines.
IPC: B21J7/24
Filed: 1967-03-14
Abstract: 1,174,295. Power hammers. KOBE-STEEL Ltd. 14 March, 1967 [14 March, 1966], No. 11874/67. Heading B3H. A high-speed hammer comprises a ram 2 with a piston 4 in a cylinder 3 formed in the upper wall of a gas-pressure chamber 1 through which the ram passes, conduits 5, 6 connecting the upper part of the cylinder through a valve 7 to the chamber and crank drive 12 to raise the ram after impact and a drive for a cam 20 to operate the valve in timed relation with the movement of the ram. The ram has a spindle extension 8 with a head 9 above a supporting frame 10 which is connected to the crank drive by rods 13. The chamber 1 is formed in a movable frame 10a slidable in guides 10b of a fixed frame 10c. The movable frame is mounted on an air cushion 26. Hydraulic-operated stopper pistons 17 have piston-rods 14 which abut the movable frame 10a when the ram is raised by the supporting frame 10 to separate the forming dies 28. In operation the valve 7 is opened to allow the pressurized gas from the chamber to enter above the piston 4. Since the upper face of the piston is larger than its lower face the piston starts to descend until it emerges from the cylinder 3 whereupon the pressurized gas acts on the piston to cause it to descend at high speed, Fig. 2 (not shown). Since the area of the upper wall of the chamber 1 is greater than that of its lower wall the movable frame is oscillated as soon as the piston 4 emerges from the cylinder 3. The stopper piston-rods 14 remain retracted. After forming the supporting frame 10 is raised by the crank and abuts the head 9 to raise the ram. Just prior to this abutment the piston-rods 14 are moved to engage the movable frame 10g so that the dies 28 can be separated. When the piston 4 is fully within the cylinder 3, Fig. 4 (not shown), the valve is closed. The frame 10 is raised further by the cranks and the stopper units 16, 17 act as hydraulic cushions, Fig. 5 (not shown). The frame 10 is then lowered and the piston-rods 14 push the movable frame 10g downwards to its equilibrium position and the rods 14 are retracted. The hammer is now ready for a further cycle of operations. In an alternative embodiment, Fig. 8 (not shown), the stopper unit 16, 17 serves solely to limit the movement of the movable frame and separate hydraulic piston cylinder assemblies (29)-(31) are provided between the rod (13) and the supporting frame (10). These assemblies act as hydraulic cushions separate from the stopper unit.

Title: Improvements in bridge-type transistor converters
IPC: H02M7/537
Filed: 1961-04-04
Abstract: 937,294. Transistor oscillator circuits. GENERAL ELECTRIC CO. April 4, 1961 [April 11, 1960], No. 11877/61. Class 40 (6). A D.C.-A.C. converter, Fig. 2, comprises a four-armed bridge circuit with a transistor 3a . . . 6a in each of the arms; a D.C. source 1a connected across a first pair of diagonally related junction points; a saturable core transformer 9a having its input winding 7a connected across the other pair of diagonally related junction points; two feed-back windings 11a, 12a which produce feed-back control signals in response to the current in the input winding; and a circuit for applying the feed-back control signals to at least two of the transistors whereby to bias either a first or a second path comprising the transistors in non-adjacent arms conducting, and the other path non-conducting, the conductive path being switched each time the transistor saturates. As described with reference to Fig. 2, four PNP transistors are employed in the bridge. The windings 11a, 12a are connected to produce pulses of opposite polarity so that as transistor 3a is switched on, transistor 4a is switched off. The emitter of transistor 3a is connected to the base of transistor 6a, and that of transistor 4a to the base of transistor 5a, so that switching of transistors 3a, 4a on and off applies a corresponding switching pulse to the other transistor in the path, e.g. switching on transistor 3a produces a negative pulse at its emitter which switches on transistor 6a to complete a current path from the source la through transistor 3a, winding 7a, and transistor 6a. Diodes 34 ... 36 are provided to shunt inductive surges. In an alternative embodiment, Fig. 3, PNP and NPN transistors are employed, each feed-back winding 11b, 12b being connected to a respective PNP and NPN transistor. Assuming the condition when a negative pulse is produced in winding 11b, this is fed to the bases of transistors 3b, 40 switching transistor 3b on and transistor 40 off. The corresponding positive pulse produced in winding 12b will switch transistor 4b off and transistor 41 on, so that a current path exists from the source 1b to the winding 7b via transistors 3b, 41.

Fig. 1 shows a known horizontal gas engine with two cylinders 2. The cylinders together with an intermediate part 3, a rear guide 4 and frame part 1 are held together by two longitudinal fixing bolts 5, 6, only one of which is shown. This known engine is modified by the provision in the part 8 of the frame 1, Fig. 3, of cylindrical plugs 11 comprising threaded bores 12 into which the ends of the associated fixing bolts screw. The fixing bolts can thus be located nearer to one another. This distance may be further reduced by special formation of the rib like walls 8a of the frame cheeks 8 as shown in Figs. 4 and 4a, Fig. 5 shows a modified form of the intermediate part 3 of Fig. 1. This part consists of two portions manufactured separately from one another, i.e. an upper and a lower portion of which only the lower portion 16 is shown in Fig. 5. This lower portion is made just high enough to enable one of the longitudinal tie rods 5 or 6 to be supported on it. The longitudinal tie rods 5 and 6 may each be surrounded by a water jacket 17 to remove the heat produced by the tensile stresses.
