Title: Machine tool control apparatus
Inventor: ALLEN ARTHUR FREDERICK
IPC: B23Q15/00
Filed: 1962-01-12
Abstract: 936,716. Machine tool details. ROLLSROYCE Ltd. Jan. 12, 1962, No. 1309/62. Class 83 (3). Stop means adapted to prevent a cutting tool and a workpiece from being adjusted relatively towards one another but which allows adjustment relatively away from each other when the workpiece has been machined to size, includes signal means controlling the stop means to prevent a new cutting operation being performed until said workpiece has been machined to size. The tool-slide 15, Fig. 1, of a lathe or other machine tool is moved by a handle 18 and screw 17 to operate a tool 20. A position detector device 23 is provided for the slide 15 and is connected to a control device 25 which contains an electronic information store and comparator circuits for comparing the signal produced by the position device 23 with a standard signal, the latter being indicative of the final cut required by the tool 20. The control device 25 is connected in a circuit 26, which includes a source of direct current 27, to a stop device 29. The circuit 26 includes solenoids 30, 31, Fig. 3, which control the position of a steel wedge 32 which selectively prevents forward or reverse rotation of the screw 17 at predetermined positions. Wedge 32 is connected to a slide block 86 with cam slots 92, 93 engaged by rollers on the ends of vertical slides operated by the solenoids 30, 31. Screw 17 is keyed to a sleeve 34, Fig. 4, to which hand wheel 18 is secured. A gear-wheel 44 is arranged on sleeve 34 with a friction grip and engages gears 56 and 60 arranged in the stop gear housing. Each gear has a reduced integral plane roller portion between which wedge part 32 fits with a cut-away portion to clear these roller portions when the wedge is central. With the wedge displaced to right or left the feed or return motion is locked. The solenoids 30, 31 move the wedge under control of a switch 112 which is operated by a plunger 116 from a spring 117 attached to a ring 120, Fig. 3. This ring is frictionally engaged with a sleeve 118 integral with gear 44 but moves only between the limits of a slot 124 and fixed stop pin 125. The solenoids are thus arranged to be operated alternately or forward and reverse rotation of the gear 44. Warning lights are also operated, green when the tool is near the end of the set cut and red when the final cutting position is reached.

Patent GB-446536-A (GB)
Title: Improvements in or relating to the production of hormones
Filed: 1935-01-16
Abstract: The process of the parent Specification in which male germinal gland hormone is extracted from crude oily materials by causing the materials to react with a substance capable of forming condensation products with the keto group is applied to very crude hormone preparations of a purity up to 15 mg. per capon unit, and is further characterized in that the ketone reagents employed do not contain salt forming groups.  Ketone reagents which are especially suitable are semi-carbazide and thio-semicarbazide.  In examples: (1) crude hormone oil of an activity of 15 mg. per capon unit is reacted with thio-semicarbazide in glacial acetic acid solution, and the crystalline product recrystallized from propyl alcohol; (2) a crude oil having an activity of 18 mgs. per capon unit is reacted in alcohol solution with semicarbazide.  The semicarbazone crystallizes out on cooling.  The Specification as open to inspection under Sect. 91 comprises also the application of the process of the parent Specification to any kind of starting material of animal or vegetable or synthetic origin and of any degree of purity.  Additional reagents for the keto group which are mentioned are aminoguanidine, phenylhydrazine and its substitution products such as p-nitro-, p-bromo-, and di-phenyl-hydrazine.  It is stated that the semi-carbazones and thio-semi-carbazones form insoluble compounds with heavy metal compounds such as silver nitrate, copper acetate and mercuric acetate which may be purified by crystallization. Additional examples are: (1) equal weights of semi-carbazide hydrochloride and sodium acetate are melted together and extracted with alcohol.  The extract is reacted with an oily hormone preparation, the condensation product purified by crystallization from propyl alcohol, and the hormone regenerated by sulphuric acid; (2) an alcoholic extract of testes with an activity of 1 mg. per capon unit is purified by convertion into its oxime using hydroxylamine.  Two detailed experimental procedures are described; (3) impure androsterone acetate is purified by convertion into its oxime using hydroxylamine acetate; (4) the male sex hormones substituted at position 3 by acyl groups may also be purified in the manner of this invention.  In addition to the subject-matter referred to above, the Specification as open to inspection contained the subject-matter of Specification 446,537. This subject-matter does not appear in the Specification as accepted.
Patent GB-1511411-A (GB)
Title: Shock absorber
IPC: F16F9/512
Filed: 1976-01-15
Abstract: 1511411 Indicating shock absorber malfunction STANDARD TELEPHONES & CABLES Ltd 15 Jan 1976 01555/76 Heading F2S An hydraulic shock absorber (or other device which produces a resistive force proportional to the velocity of one part of the device relative to another) is provided with a mechanism which indicates when the shock absorber is no longer in good working condition. The mechanism includes a member 6, 8, 9 acted on by drag forces (viscous, not shown, and/or electromagnetic) and opposing fluid pressure forces developed by the shock absorber during operation. These opposing forces normally balance to keep the member stationary, but, when the shock absorber is not functioning efficiently, the drag force overcomes the fluid pressure force and so the member moves and provides a signal. The shock absorber comprises a piston 3 and piston rod 4 slidable in a cylinder 1 against a fluid resistance proportional to the piston velocity developed by valves (not shown) in the piston 3, the piston rod guide 4a and the cylinder base 5b. The member 6, 8, 9 is free to move longitudinally with respect to the cylinder 1 and to the hollow piston rod 4. The member comprises a cylinder 6 of aluminium or copper which co-operates with permanent magnets 7, a connecting rod 8, and a piston 9 which slides in a cylinder 10 and is acted on, via orifice 11, by the fluid pressure in the cylinder 1. In operation, on compression of the shock absorber, viz. movement of the piston rod 4 downwardly, movement of the permanent magnets 7 relative to the cylinder 6 induces in the latter eddy currents which tend to cause the member to move downwardly too. However the increased fluid pressure in the cylinder 1, and thus in the cylinder 10, tends to cause the member to move up. Should the fluid pressure force be reduced, the drag force predeminates, the member moves down and the orifice 11 communicates the pressure in the cylinder 1 to a chamber 13, which causes visible movement of a rod 15, or visible rupturing of a diaphragm, or operation of a switch.

IPC: F42C15/23
Filed: 1916-08-04
Abstract: 124,493. Davy, W. J., and Blake, E. W. Aug. 4, 1916. Projectile fuses. - Consists in providing in a percussion grenade a spring-urged firing- pin b, which is normally held in a cocked position by unstable or easily displaceable means, such as an eccentrically weighted ring t, operative to fire the grenade on impact, and which is also positively held by other means, such as a safety-pin v, released automatically by the unwinding of a tape x after the discharge of the projectile. The tape, which has a weight x' at one end, is wound round the neck w of the grenade, and is normally secured by means which can be readily unfastened before the grenade is thrown. In a modification, instead of the ring t, a circular weight holds up the firing- pin indirectly, through the interposition of a pivoted catch against which the safety-pin bears. Reference has been directed by the Comptroller to Specification 124,837.

Title: Improvements in gas turbine marine propulsion plant
IPC: B63H23/00
Filed: 1958-01-17
Abstract: 871,963. Nuclear power plant. SOC. RATEAU, and ANXIONNAS, R. Jan. 17, 1958 [Jan. 17, 1957], No. 1745/58. Class 39(4). [Also in Group XXVI] In a marine propulsion plant comprising a main gas turbine plant for ahead travel and an auxiliary steam turbine for braking and astern travel which derives its energy from a steam accumulator, the gas turbine cycle includes a high pressure compressorturbine and a low pressure turbine which provides the ahead drive and the steam generator consists only of a pressurised hot water accumulator heated by gas obtained from the gas turbine plant in operation. Air compressed in a compressor 1a, 1b and cooled in intercooler 21, Fig. 3, is first heated in a heat exchanger 2a, 2b and then in a heat exchanger 28 before passing to the turbine 4 driving the compressor 1a, 1b. The turbine 4 discharges through an ahead turbine 5 and the heat exchanger 2a, 2b to the intake of the compressor 1a, 1b. A water heater 8 is arranged between the two parts of the heat exchanger 2a, 2b. The heat exchanger 28 is heated by a nuclear reactor 24. A valve 10 and by-pass 11 with control valve 11a and cooler 23 are provided to isolate the ahead turbine 5. The accumulator 13 supplies steam to the astern turbine 14 which discharges to a condenser 15. When the turbine 14 is running the turbine 5 is isolated. There may be more than one turbine 4 with reheating between the stages. Hot water may be taken from the accumulator for outside needs. To enable the nuclear reactor to act independently of the plant, a valve controlled by-pass 22 is arranged around the initial stages of the turbine 4 to -control the speed of the compressors so that the gas conditions before and after the turbine 4 remain constant. The working fluid is heated by the coolant of the nuclear reactor which is circulated by a pump 25. Valves 26, 27 cause the coolant to flow through the heat exchanger 28 or a cooler 29. To pressurise and scavenge the gas turbine circuit, a compressor 33 driven by a turbine 34 and motor 35 is provided. The heat for the steam accumulator can be derived partly from the nuclear reactor or from any other heat source. The reactor can be of any kind. Its coolant can be a gas or a liquid such as molten metal or even a fluid containing the fuel as is relatively homogeneous reactors containing a super-critical volume reacting chamber. The gas turbine working fluid can be used as the coolant. The astern turbine is preferably of the type shown in Fig. 4 and consists of two elements 39, 40. The element 39 is designed for efficient astern operation and the element 40 is designed to provide a braking torque. The valves 45, 46 are controlled by the ship's speed and change-direction operation limited to operation of the valve 16. The valve 16 can be operated simultaneously with or subsequently to the valves 10, 11a. Some of the steam from the accumulator 13 may be led to an ahead turbine.

Abstract: 435,161. Autographic recorders. BLACK, H. D., 39, St. James's Street, Pall Mall, London, and WEBB, C. F., 24, Deane Way, Eastcote, Middlesex. March 5, 1934, No. 1747/35. Divided out of 434,601. [Classes 106 (i) and 106 (iii)] In an autographic recorder having means for feeding superimposed fan-folded voucher and record strips to the exterior and interior of the apparatus, respectively, the record strip passing around the periphery of a rotary member and being folded into the storage receptacle by a rocking lever swinging first in one direction and then in the other as successive forms pass from the rotary member, the rocking lever is actuated by engagement with a surface that is rotatable as one with and about the axis of the rotary member. The folded voucher and record strip are fed from a compartment in the right-hand side of the casing, Fig. 1, via a roller 7 and feed closure 8 to a writing plate 10. After leaving the writing plate, the voucher strip passes out through a slot 15 while the record strip is fed by a drum 13 to a compartment on the left-hand side of the casing. The feed drums are driven by a hand-crank 2 operating through a pin-wheel 22 and a gear 18. The strips are apertured for aligning purposes, such apertures taking over teeth 16, 17 projecting from the feed drums. To ensure that the record strip is correctly folded in the storage compartment, a lever 24, Fig. 2, is provided to guide the strip into the compartment. In the position shown, the arm 26 of the lever allows the leading edge of a form to proceed towards the right, the other arm 25 of the lever projecting at this time through a slot 23 in the drum. However, as the drum rotates it engages the arm 25 and swings the arm 26 against the action of a spring 27 to the position shown in dotted lines, in which position it deflects the leading edge of the next succeeding form to the left. Indications are provided on the drum 13 to show what its position should be for feeding a first form that bears an even or an odd serial number. Clips 30 are provided to clamp the leading edge of the first form, these also are marked " even " and " odd." A gong 21 is operated once in each operation.
