Title: Machine for drawing and shearing of wire or bars
IPC: B21D43/28
Filed: 1968-07-15
Abstract: 1,223,300. Shearing. VYZKUMNY USTAV TVARECICH STROJU A TECHNOLOGIE TVARENI. 15 July, 1968 [24 July, 1967], No. 33616/68. Heading B3W. A machine for drawing and shearing wire or bars 50 comprises a drawing die 48, and a crank-shaft 4 which through connecting rods 13 and 6 actuates a feed device 23, a hold-down 41, a shear blade 35 and a slug-supporting device 36. A stationary blade 46 is mounted in a support adjustable relative to the machine frame 1 to vary lateral clearance between the blades. The feed device 23 comprises tapered jaws 26 and is connected to the connecting rod 13 by links 21, 19 and slide shoe 15 adjustably mounted, for varying the feed stroke, in lever 17. The connecting rod carries a pin 27 on which are pivoted links 28 and 29 connected to a shear slide 30 and a slug-supporting slide 32 respectively and a pin 27 on which is pivoted a lever 38 connected to a bell-crank lever 39 which forms the hold down and is pivoted about a fixed pin 40 on the machine frame 1. The arrangement of links 28 and 29 on the connecting rod 6 is such that during shearing the slide 32 carrying the slug support 36 clamps the slug against the blade 35. After shearing, a spring 42 raises the slides 32 and 30 until the axis of the slug coincides with the axis of the stock at which point movement of the slide 32 is prevented by a stop nut 44. The shear slide is returned to its initial position by continued upward movement of the connecting rod, releasing the slug which is ejected by the advancing stock on the next feed stroke.

Patent GB-1172008-A (GB)
Title: Improvements in or relating to Hydraulic Pressure Modifying Devices
IPC: B60T8/26
Filed: 1967-07-21
Abstract: 1,172,008. Pressure-reducing valves. SOC. ANON. D.B.A. 21 July, 1967 [4 Aug., 1966; 29 June, 1967], No. 33691/67. Headings F2F and F2V. An hydraulic pressure modifying device for a vehicle braking system comprises a normally open valve between inlet and outlet chambers controlled by the pressure in the outlet chamber to close the valve when the inlet pressure is above a predetermined value, the valve seat being movable towards the outlet chamber against the force of resilient means, means being provided to oppose the displacement of the pressure-responsive element which is connected to the valve control member by retractable means. In the device of Fig. 1, a through path is normally open from the master cylinder 12 to the brake cylinders 14 via inlet chamber 44, orifice 30 and outlet chamber 46. When the pressure in the latter reaches a predetermined value a piston 32 is driven back against a spring 42 until it reaches an abutment 52. A U- shaped piece 60 bears against the piston and is driven with it by a spring 64, carrying with it a head 56, valve stem 54 and valve closure member 50, thereby closing the orifice 30. Further increase of inlet pressure drives the piston 28 backwards against a spring 38, the valve 50 remaining closed, the decrease in volume of chamber 46 causing the outlet pressure to rise, but at a lower rate than the inlet pressure. The relationship between the two (preferably linear) depends on the characteristics of spring 38. In a modification (Fig. 2, not shown) the piston 32 and spring 42 are replaced by an elastomeric diaphragm, to the other side of which a modifying pressure can be introduced, e.g. representing axle loading. The piston 28 and spring 38 are also replaced by an elastomeric washer. In another modification (Fig. 3, not shown) both piston-spring assemblies 28/38/64 and 32/42 are replaced by elastomeric rings of circular cross-section as in Specification 1,148,557. The spring 62 is replaced by a further spring (78) between the head 56 and a plate (76) bearing on the right-hand ring. In both these modifications the abutment 52 is omitted. The different features of the various modifications shown may be combined in any way.

Title: Method of removing aluminum oxides from aluminum-killed steels and steels produced by such method
IPC: B22D7/00
Filed: 1962-09-04
Abstract: To remove oxides from aluminium-killed steel, uranium is added whereby uraniumaluminium oxide compounds of high density are formed; the steel is then poured under such conditions that settling out of these compounds is substantially complete before solidification occurs, whereby an ingot is formed, a major portion of which is free of said compounds and is subsequently separated from the minor bottom portion in which they are concentrated.  The uranium may be added either in metallic form or as ferro-uranium or aluminium-uranium alloy. Further deoxidation beyond that resulting from the addition of aluminium is said to occur.

Abstract: 174,506. Webster, C. W. Dec. 2, 1920. Bell-operating mechanism, hand. - Relates to a mechanically-operated door bell in which a shaft P of small diameter extends through the door and engages a turning-member T, one end of which may operate in a guide T<1> formed in the bracket T<2>. The turning-member consists of a coarse-threaded rod, and the guide T<1> is shaped accordingly. The other end of the turning- member is in the form of a pin passing through a hole in the middle cross-piece of the bracket T<2>. On this pin a boss carrying a pinion T<6> revolves. When the shaft P is operated, the turning-member T is moved through its guide and the rotary movement is transmitted to the gearwheel T<3>. This wheel gears with a long pinion T<4>, along which it travels, and the pinion T<6> is rotated by the gear-wheel T<5>. The pinion T<6> is in connection with the arms C' so that rotation causes the clappers C to strike the gong. On releasing the press button P<1>, the gear-wheel T<3> is pressed into normal position by a spring S, so that the movement of the gear-wheels is reversed and the bell rings again.

Title: Improvements in or relating to the vaporisation of hydrocarbons
IPC: C07C7/163
Filed: 1958-10-24
Abstract: <PICT:0826607/III/1> A process for the catalytic hydrogenating refining of hydrocarbons such as petrol, benzene and gas oil which, in the presence of hydrogen, are vaporized in a double or more effect vaporizer through which they pass in succession in admixture with hydrogen before being refined and which in the course of their vaporization are maintained in circulation through each vaporizer effect by the action of the hydrogen as in an air-lift pump in such a manner that only the liquid phase flows through the heating system of the vaporizer, in which the vaporizers are heated by the gas-vapour mixture emerging from the hydrogenating catalyst refining reaction after the mixture has transferred some heat to the gas-vapour mixture which is about to enter the refining reaction, in such manner that the gas-vapour mixture which serves as the heating medium flows in succession through the heating systems of the several vaporizer effects, entering the last and leaving the first effect the hydrogen and hydrocarbon being conducted through the vaporizer effects in countercurrent to the heating medium. Fine solid impurities which cannot be removed by filtration such as iron dust, rust and iron sulphide can be removed from the process before they have been able to form deposits on the walls of the apparatus.  In a preferred apparatus comprising a sextuple-effect vaporizer of which heater 12 is the last of 6 identical heaters the benzene vapours from the vapour head 30 of the final heater 12 enters the column 58 which operates as a scrubber.  After undesirable higher-boiling substances have been removed the benzene vapours flow through a pipe 51 through heat exchangers (not shown) where their temperature is raised to that required for the catalytic reaction in the reactor (not shown). The scrubbing medium leaves the column 58 through a pipe 52 and after passing through a heat exchanger 53 is conveyed by a pump 54 through the pipe 59 into the first heater.

Patent GB-383085-A (GB)
Title: A process for the production of clear and transparent artificial resin masses
IPC: C08L61/10
Filed: 1931-12-10
Abstract: Clear and transparent artificial resin masses are made by the direct hot compression of resitols which are entirely, or almost entirely, free from volatile constituents and which contain some resol (5-25 per cent) and which have not been converted into the resite phase to such an extent that compression is no longer possible.  The resitols may be prepared by subjecting resols or liquid or semiliquid, viscous or solid initial resol condensation products in a finely divided condition to the action of heat. Hardening agents may be added to the resols before or during the resitol formation.  Mixtures of novolacs and substances which contain reactive methylene groups, e.g. hexamethylenetetramine may be used instead of resols as starting materials.  Patterns and/or colours may be produced in the finished products by adding fillers and/or pigments to the resitol or by employing coloured resitols. Specification 350,427 is referred to. The Specification as open to inspection under Sect. 91 (3) (a) comprises also the use of resitols made by heating soluble and fusible condensation products of phenol and aldehydes capable of hardening (resols) in thin layers to a high temperature for a short time.  This subject-matter does not appear in the Specification as accepted.

Title: Automatic ventilating and cooling system
IPC: F24F11/08
Filed: 1953-12-14
Abstract: 728,281. Automatic temperature control systems. VAPOR HEATING CORPORATION. Dec. 14, 1953 [Jan. 7, 1953], No. 34788/53. Class 38 (4). In a railway car a blower supplies a fixed quantity of air, a proportion of which, dependent on the setting of a motor-driven damper, has passed through a cooler. The amount of cooling is adjustable by a pre-set damper which determines the amount of re-circulated air. Car temperature is maintained constant by thermostats within the car controlling the motor-driven damper. In Fig. 2 the cooler D is switched on and off by a relay C<SP>1</SP> under the control of a thermostat C. A reversible motor 69 operating the damper is controlled by relays A<SP>1</SP> and B<SP>1</SP> under the control of cycling thermostats A and B. Thermostats A, B, C, which are each responsive to car temperature, are biased by heaters 76, 77 and 78 respectively. The operating temperatures of the three thermostats are simultaneously adjustable by operation of a switch E to select, through contacts 3, 4, 5 or 6, a resistor 79, 80, 81 or 82 in series with a parallel arrangement of the thermostat heaters. A resistor 77<SP>1</SP> in series with heater 77 raises the operating temperature of thermostat B relative to thermostats A and C. Switch E may be set to close contact 1 only, to switch on a blower 12 and provide ventilation without temperature control. When switch E is set to close also contact 2 and one of contacts 2, 3, 4 or 5 for automatic control, the cooler D is brought into operation if the temperature rises to the operating temperature of thermostat C. A resistor 101 then increases thermostat heater energization to ensure that the cooler remains operative for a period. At temperatures above the operating temperature of thermostat C the cooler is operative, thermostats A and B operate cyclically, and the arrangement is such that if the temperature rises the change in the relative times of operation of relays A<SP>1</SP> and B<SP>1</SP> causes adjustment of motor 69 to increase the proportion of cooled air but if the temperature falls the change in the relative times of operation of relays A<SP>1</SP> and B1 causes adjustment of motor 69 in the reverse - sense. Thermostat heater energization is modified when heater 76 is switched off by relay A<SP>1</SP>,  or when resistor 102 is introduced by relay A<SP>1</SP>. or B<SP>1</SP>. A resistor O is substituted to prevent modification of heater energization when heater 77 is switched off by relay B<SP>1</SP>.
