Title: An improved jack adapted to be mounted on and co-operate with a threaded rod in a load lifting apparatus
IPC: B66F1/08
Filed: 1962-04-02
Abstract: 990,526. Step-by-step jacks. E. J. VON HEIDENSTAM. April 2, 1962 [Dec. 11, 1961], No. 12537/62. Heading B8J. An hydraulic jack comprises a threaded rod 1, supporting nuts 2, 3, and an hydraulic ram consisting of an annular cylinder 4 and piston 5 having flanges 12, 15 engaging in grooves in the nuts 3, 2. The nuts are rotated alternately by an hydraulic torque motor comprising an annular channel 18, Figs. 1, 3, in the nut 2 enclosed by a sleeve 19 which is rotatable around the nut, which is provided with a vane 20 and which is connected to the nut 3 by a clawcoupling 21 so that the sleeve is axially but not rotatably movable with respect to the nut 3. Stops 38a, 38b, 39a (not shown), 39b, mounted on a ring 37 supported on the upper end plate 6 of the cylinder 4 engage a tooth 34 on the nut 3 to limit rotation of the nut 3. In operation, to raise a load supported by the cylinder 4 when the rod 1 is stationary, fluid is supplied to the chamber 10 beneath the piston 5 thereby raising the piston and raising the surface 16 of the piston flange 15 from the shoulder 17 on the nut 2, the flange 12 of the cylinder 4 being supported on the shoulder 14 of the nut 3. Fluid is then supplied to the chamber 22, Fig. 3, to rotate the nut 2, since the sleeve 19 is secured to the nut 3 which is prevented from rotating by the friction between the flange 12 and the shoulder 14. The nut 2 is rotated until the shoulder 17 engages the surface 16 of the piston which is at its upper limit of travel in the cylinder 4. Fluid is then supplied to the chamber 9 above the piston 5, thereby raising the surface 13 of the cylinder 4 from the shoulder 14 on the nut 3 and releasing the tooth 34 on the nut from the stop 38a. On supplying pressure to the chamber 23, Fig. 3, as the nut 2 is prevented from rotating by the engagement of the shoulder 17 with the flange 15, the sleeve 19 and, therefore, the nut 3 are rotated, this rotation being limited to half a revolution by the stop 38b. Pressure fluid is then discharged from the chamber 9 allowing the cylinder 4 together with the load to'sink until the surface 13 of the cylinder flange 12 rests on the shoulder 14 of the nut, Fig. 1, and the cycle is repeated. In each cycle, the load is raised by a distance corresponding accurately to half a revolution of the nut 3 on the rod 1. In a modification, the load is attached to the rod 1 and the cylinder 4 is held stationary. The nut 3 is provided with a cam 42 associated with microswitches which are actuated at the end of each complete cycle. A device may be provided to count the rotations of the nut 3. In further modifications (not shown) two or more hydraulic motors are coupled together to rotate the nuts through more than half a revolution and these hydraulic motors may be replaced, by electric motors. A plurality of jacks may be interconnected through the microswitches to lift a load such as a slab on a building site.

Title: Improvements in the treatment of vegetable and silk material with chrome mordants
IPC: D06P1/00
Filed: 1928-10-24
Abstract: 324,358. Hankey, J. L. Oct. 24, 1928. Fireproofing.-Vegetable or silk fibre is treated with a solution comprising a chromate or bichromate of a fixed alkali and a sulphoxylate compound, in the absence of ammonia, and then aged. Increased quantities of chromium are thereby absorbed and the fibre made fireproof. The fibre may be subsequently treated with known water soluble fireproofing compounds, such as ammonium sulphate or phosphate, sodium tungstate, borax or boric acid. In an example, a solution of sodium bichromate containing dilute caustic soda and a solution of formosul are mixed, dry bleached cotton treated therewith, and the fabric then aged with moist steam, rinsed and dried. To remove alkali, the fabric may be finally rinsed in dilute acetic acid. Glucose and glycerine may be added to the bath to render the solution stable. Britulite and the compounds having the Registered Trade Marks " Rongalite " and " Hydraldite " are also mentioned as sulphoxylates that may be used. Specification 117,715, [Class 15 (ii), Dyeing, Processes &c. for], is referred to.

Title: Improvements in or relating to the lubrication of air or like pressure fluid rotary motors
IPC: F16N7/30
Filed: 1926-05-17
Abstract: 276,064. Lithgoe, J., and Richardson, D. E. May 17, 1926. Lubricant conveyed by fluid.-Lubricant entering a rotary air or like fluid-pressure motor with the pressure fluid is supplied, without the aid of valves, by the excess of pressure at or towards the initial point of entry of the fluid over its pressure at or near its point of admission into the working space during the working of the motor. An oil chamber D arranged below the motor cylinder B communicates above the level of oil through passages d with the inlet end of the pressure-fluid passage E. Small inclined channels d<1> extend from the lower portion of the chamber D into the port F leading from the passage E to the cylinder B. During the working of the motor the slight decrease in pressure due to friction and other disturbances between the inlet end of the passage E and the port F causes oil to flow through the channels d<1> to the port F. According to tthe Provisional Specification the pressure fluid passes through the oil chamber, the drop in pressure as it passes therefrom to the cylinder causing the flow of oil.
Patent GB-569891-A (GB)
Title: Improvements in or relating to loading ramps or the like
IPC: B65G69/28
Filed: 1943-08-05
Abstract: 569,891. Loading vehicles. SHELVOKE & DREWRY, Ltd., and EDWARDS, C. K. Aug. 5, 1943, No. 12666. [Classes 78 (ii) and 78. (iv)] In ramps for use in transferring loads to or from a wheeled vehicle or stationary platform of the kind which are arranged to be turned upwards from the operative position through a dead-centre position to rest upon the vehicle or platform when not in use, two spring mechanisms are provided which operate respectively on each side of the dead-centre position to counteract the gravitational turning moment on the ramp. The vehicle 1, Fig. 1, which is a large lorry designed to carry another vehicle, is provided at its rear with two ramps 7 which are spaced apart and each of which is of sufficient width to take the wheels or tracks of the carried vehicle. Each ramp is provided with a shaft 10 which is connected by links 8, 9 to a shaft 2 mounted at the rear of the vehicle. These links are free on the shafts 2, 10 and have extensions 11 which are pivotally connected to tension springs 12, 13 secured to the ramp by pivotal connections. A cam 23 fixed to the shaft 2, Fig. 2, has a peripheral groove which receives a cable 20. One end of the cable is attached to a ring 19 against which bears a compression spring 16 mounted in a tubular structure 17 on the lorry. The other end of the cable is secured to the cam at a point beyond the end of the groove. An arm 28 fixed to the shaft 2 carries an adjustable bolt 27 which bears against an abutment 29 on the ramp. By this means the spring 16 exerts a turning moment on the ramp and assists its lifting when manual force is applied to the handles 30, 31. This moment decreases as the ramp rises, since the cam 23 turns with the shaft 2, but bears a substantially fixed relation to the turning moment due to gravity. When the centre of gravity of the ramp is vertically above the shaft 2, the cam is in engagement with a stop which prevents its further rotation and the spring 16 ceases to exert any pressure on the ramp. At the same point the rotation of the links 8, 9 about the shaft 2 is arrested by stops, and in consequence the springs 12, 13 become stretched when the ramp is turned beyond the dead-centreposition to lie on the vehicle. Specification 566,032 is referred to.

Title: Improved manufacture of halogen derivatives of organic compounds
IPC: C07C17/10
Filed: 1928-04-30
Abstract: 289,795. Polanyi, M., and Bogdandy, S. von. April 29, 1927, [Convention date]. Methyl chloride; halogen derivatives of hydrocarbons. - Halogen derivatives of organic compounds, more particularly of hydrocarbons, e.g. methane, are produced by bringing together in the vapour state the halogen and the hydrocarbon mixed with a body capable of combining more rapidly than the hydrocarbon w i t h the halogen and thereby initiating the reaction. Alkali metals in particular are suitable as "initiators." In the production of methylchloride the apparatus utilized comprises a jacketed chamber a into which a mixture of chlorine and methane is admitted bv the inlet c and methane and sodium vapour through the inlet d. The sodium vapour is provided by passage of methane over metallic sodium contained in a heated vessel g. Cooling jackets b, c are provided to keep the temperature in the chamber a from rising above 300‹ C. When the temperature of vaporization of the hydrocarbon is above 300‹ an inert carrier gas such as nitrogen is employed to convey the hydrocarbon vapours into the reaction space or the reaction is carried out under reduced pressure. The Specification as open to inspection under Sect. 91 (3) (a) comprises also the use as initiators of metals other than alkali metals, of non- metallic substances such as arsenic or phosphorus, and as hydrocarbons suitable for halogenation higher homologues of methane such as pentane and C18H38 and aromatic hydrocarbons. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in or relating to clips
IPC: H04R25/04
Filed: 1952-05-21
Abstract: 769,525. Clips. DENT, Ltd., R. H., and HOYLES, L. May 21, 1953 [May 21, 1952], No. 12851/52. Class 44. [Also in Group XXXIX] A clip assembly for securing an article (e.g. a hearing aid) which includes a case to a support (e.g. coat pocket) by gripping the support between a clip member and the case, comprises a clip member provided with two arms adapted to lie against a surface of the case when the clip member is in the gripping position, each arm having attached thereto a pin member extending into the case and acted upon by biasing means disposed within the case so as to tend to maintain the clip member in gripping position. The clip member 13 has two angle-section arms 14 normally resting on the end wall 11 of a hearing- aid case 10 and disposed on either side of microphone grille 12 set in the wall. Each arm 14 is pivotally actuated to a pin member 15 passing through a hole in a flange 16a of a supporting member 16. Each pin member carries a cross-arm 17 slidable on the limbs 18a, 18b of a U-shaped member 18 carried by the flange 16a and each limb carries a compression spring 19 between the flange and the cross-arm. The springs urge the pins into the case and thus the member 13 towards its gripping position. When the clip member is moved to the position shown in broken lines in Fig. 2, the free ends of the arms pivot on the case wall 11. The supporting members 16 each have a flange 16b which hooks under the lower edge of the grille 12 and the springs 19 act to hold the members 16 in position. According to the Provisional Specification, a compression spring may be inserted over each pin and act between the case and a washer carried by the pin. Also the clip can be reversed so that the member 13 will coact with the other side of the case. Specification 769,524, [Group XXXIX], is referred to in the Provisional Specification.

Title: Hoisting engine controls
IPC: B66B5/08
Filed: 1924-05-26
Abstract: 237,390. Lilly, W. J., and Logan, H. H. May 26, 1924. Overwinding and overrunning, preventing, and emergency power cut-off gear.- Comprises mechanism in which a cam or the like the movements of which correspond with those of the cage, operates end stop gear, and a centrifugal governor operates over-speed stop gear, the stop means including a circuit having a switch which may be opened by the governor and a pair of switches either of which may be opened by the cam. A cam disc 9 positively rotated from the winding drum carries a pair of retarding cams 10, 11, one for each direction of rotation, final stop cams 14, 15, a cam for operating a warning bell 74 just before the end of the wind, and a pair of cams additional to the retard ing cams for slowing down the cage at an earlier point when men are being carried. The last cams are brought' into use by means which also impose a lower speed limit than that normally imposed by a centrifugal governor 29. The governor, which is controlled by a dashpot 47 and an adjustable weight 48, operates a lever 38 carrying a contact member 63. When the speed becomes excessive this member rises and makes contact with a spring member 64, so closing an alarm bell circuit. If the speed still rises, the member 63 compresses the spring 64 and raises a pivoted arm 50, Fig. 4, to open switch contacts 52, 54 of a circuit controlling the hoisting engine and the brakes. The contacts 52, 54 are carried by an arm 49 connected to a lever 69 having a roller 70 acted upon by one of the retarding cams according to the direction of movement of the cage. The effect of this is to bring the arm 49 and the spring contact 64 nearer to the governorcontrolled contact 63 and so to lower the speed at which the governor acts. At the end of the wind one of the stop cams 14, 15 acts on a roller 28<a> or 27<a> and opens another switch 22 or 21 in the circuit controlling the engine and the brakes. For carrying men a lever 102, Fig. 3, is raised or lowered from the central position shown and (1) rocks an arm 97 on the axis of the roller 70, thus bringing one of a pair of rollers 98 into the path of an additional retarding cam (not shown) which acts at an earlier stage than the main cam 11. and (2) lowers the switch-carrying arm 49 so that the governor will act at a lower speed. At the same time the lever 102 closes switch contact's 106 or 107, giving notice through lamps to the engineer and the men at the top and bottom of the shaft that' the additional safety control is in action. The various cams are adjustably secured to the disc 9. Specification 152,466 is referred to.
