Title: Jack
IPC: B66F3/12
Filed: 1948-07-22
Abstract: 656,619. Jacks; load-handling apparatus. WHITE, A. A. July 22, 1948, No. 19644. [Class 78 (iii)] A portable jack adapted to be placed under a motor car consists of a base on which are pivotally mounted two struts which extend divergingly upwards and carry at their outer ends automobile-supporting means, one of the struts being extensible by means operable from its outer end. In one form, Fig. 2, the two struts are mounted on a common pivot 24 on a base 21. The extensible strut consists of two telescoping tubes 26, 27 and the other strut of a pair of tubular members 35a, the outer portions 35 of which are flattened. The lower ends of members 35a are pivoted at either side of member 26 on the pivot 24. The outer ends are pivotally connected at 39 to a beam consisting of two portions 36, 38 hinged together at 37, the other end of which is pivotally connected to the outer end of the extensible strut at 30. The hinge 37 permits only upward bending from the position shown. By this means the jack may be folded as shown in Fig. 5. The means for extending the telescoping tubes 26, 27, Fig. 6, consists of a screwed shaft 29 which is mounted in a bearing 31 in the outer end of tube 27, and which engages a screwed collar 28 on the outer end of tube 26. The screw 29 is rotated by a handle 40, Fig. 2, pivoted at 41 to the screw for folding. A peg 32 at the inner end of the screw prevents complete withdrawal of the screw from the collar 28. In use, the tubes 26, 27 are first telescoped inwards to lower the beam 36, 38 after which the jack is placed under a motor car and the beam is raised by extending the strut 26, 27 until it engages two parts, e.g. the axle and the bumper of the car. Engagement may be facilitated by providing pegs 42 on the beam or preferably the bumper rests on a sliding block 43 while the axle is clamped to the beam. Further extension of strut 26, 27 then raises the car. In a modification, Fig. 8, a base 50 is provided with two pivots 53, 54 on which the inner ends of the two struts are respectively mounted, the extensible strut consisting of two telescoping tubes 58, 59 while the other strut is a tube 56. A chain 66 for supporting the load is stretched between a connection 67 on the outer end of tube 56 and a hook 65 on tube 59, the height of the chain thus being adjustable by altering the length of chain prior to lifting the load.

Title: Improvements relating to electric railway control systems
IPC: B60L15/12
Filed: 1921-07-21
Abstract: 167,166. Metropolitan-Vickers Electrical Co., Ltd., (Assignees of Hall, A. J., and Mardis, P. L.). July 30, 1920, [Convention date]. Master control systems; safety arrangements.- Relates to means for reinserting resistances and subsequently cutting off current from a motor in the event of overload or other abnormal conditions. The invention provides an electromagnetic switching device 17, controlled by overload and excess voltage relays 42, 44, a line switch actuated by a coil LS, and resistances 40, 41 sectionally controlled by contactor windings 1 to 7. The parts are shown in a power circuit diagram Fig. 3 and a control circuit diagram Fig. 4, the control circuit being energized by a battery B. The effect of overload or excess line-voltage is to de-energize the resistance contactors in two successive steps, and by de-energizing a coil 16<a> also to initiate a movement of the switching device 17 from a position Rs to a position Tr. The movement of switch 17, which is adjusted so that it is not completed until all the resistances have been reinserted, finally breaks the circuit of the line switch LS and thus cuts off power from the motor. In starting again, a master controller MC must be moved into its off position, which reenergizes coil 16<a>, consequently resetting switch 17, and also energizes coils 50, 51 which reset the automatic relays. A particular construction of the device 17 and its operating machanism is described in the Specification and comprises a pneumatic cylinder, a piston working against a spring, and a racked piston-rod geared to a rocking drum carrying the required contact segments. The cylinder is controlled by an electromagnetically operated valve, the winding of which is represented by 16a in the control diagram. The invention is specially designed for electric railway motors.

Title: Improvements in apparatus for the controlled germination of grain during malting
Filed: 1947-07-23
Abstract: 633,013. Air conditioning. STEWART, Sir F. C. July 23, 1947, No. 19706. [Class 137] [Also in Groups VI and XXXV] An apparatus for the controlled germination of grain during malting comprises a fan 1, an air conditioner 2, a germinating chamber 8, air circulating ducting 5, 6, 7 including an inlet 81 for fresh air and an outlet 9 for exhaust air each having respectively valves 10, 11 operated by a servo motor 12 under the influence of a thermostat 13 (see Group XXXV), a control device 14 responsive to changes in the proportion of CO 2  present in the system, said device being operative to override the functioning of the valve-controlling thermostat when the rate of intake air is insufficient to maintain efficient germination. A source of heat 3 is arranged in the air stream to the air conditioner or may be in a spray water circuit of the conditioner. Cooling means may also be provided for the spray water. The thermostat may include a differential thermostat of the wet bulb type having-one bulb located in the air circulating system and another bulb located exteriorly of the system. To prevent the germination temperature rising above a preferred level the thermostat acts to open the air inlet valve 10 to allow more fresh air to be drawn in and should the temperaturg fall too low the valves are closed. If the CO 2  content increases too much the control device operates to override the action of the thermostat should this have caused the valves to close to prevent the temperature from falling. Should the outside wet bulb temperature rise so that the fresh air passing through is incapable of absorbing the germination heat, chilled water is introduced via pipe 16, two-way valve 17 and spray pump 15 into the air conditioner. The chilled water supply is controlled by a servo motor 18 operating the valve 17 and to which current is fed directly or through a relay by the closing when the valve 10 is fully open of a switch associated with the servo motor 12. The differential thermostat' 19 having both bulbs of the wet bulb type are 21 being located in the air duct 5 and the other 22 in the outside air operates when the outside wet bulb temperature exceeds the germinating temperature by bringing the servo motor 12 to the position where fresh air is shut off except as demanded by the control device 14. If the atmospheric temperature is low, heat is supplied to the air circulating system and controlled by a switch on the motor 12 which closes when the valve 10 is closed and directly or through a relay feeds current to a servo motor 23 controlling the supply of the heating medium or operating a contacter controlling the electric supply.

Filed: 1943-11-25
Abstract: 583,857. Winding thread &c. FOSTER MACHINE CO. Nov. 25, 1943, No. 19707. Convention date, Jan. 16. [Class 120 (ii)] A method of, and apparatus for, winding thread &c. to produce a barrel-shaped package comprises laterally traversing and feeding thread &c. on to a rotating core, progressively and alternately increasing and decreasing the length of the traversing stroke, accelerating the lateral feed from the ends to the middle of the package and decelerating the lateral feed from the middle tc the ends of the package. The thread 'guide 14 is carried by a lever 13 pivoted at 19 to a lever 16 pivoted at 18 to a cross head 8 secured to a tube 7 reciprocated by a main traverse cam 4. This cam gives uniform traverse. A roller carried by a block 34, slidable along guide rods 35, is'held in contact with edge cam 25 by a spring 38. The auxiliary traverse cam 25 has the effect of making the velocity of traverse a maximum when the levers 13, 16 are vertically positioned (Fig. 1) while it is a mini-. mum at the ends of the stroke, slots 15, 36 allowing for the sliding motion of the levers. The profile of the auxiliary cam 25 is such that six lobes occur about its circumference to effect a gradual shift of the traverse and a lengthening thereof, followed by a further gradual shift and shortening of the traverse as the wind proceeds towards the middle thickness followed again by a gradual shift in reverse and lengthening of traverse and again by shortening of traverse, as the winding is completed; (Fig. 9). In the example described, the main traverse cam 4 made 76 revs. to one of the auxiliary cam 25.

Title: Butyl alcohol fermentation process
IPC: C12P7/28
Filed: 1935-07-12
Abstract: In a fermentation of the clostridium saccharo-acetobutylicum type in which the fermenting medium comprises an essentially soluble mash containing monose sugar as one of the principal components, the fermentation is effected in the presence of ammonia nitrogen and 10 per cent or more of grain alcohol distillery slop.  A preferred form of monose sugar is hydrol, i.e. a waste residual material from the corn sugar industry containing about 55 per cent of glucose and 18 per cent of higher carbohydrates.  The ammonia nitrogen may be provided by ammonia or ammonium salts such as the sulphate in proportions of 0,1 to 0,5 per cent by weight.  The grain alcohol slops as from yeast fermentations may be in proportions of 30 to 40 per cent by volume.  The hydrogen ion concentration is regulated so that the final value ranges between 5,0 and 6,2.  This is preferably done by neutralizing the slop to a pH of approximately 6,2 by soda ash and then incorporating a slight excess of insoluble neutralizing agent, e.g. freshly precipitated calcium carbonate into the mash. Where the mash contains sufficient alkaline buffer as in one containing beet molasses, the addition of alkaline materials may be unnecessary.  In examples: (1) a hydrol mash containing grain alcohol distillery slop (NH4)2SO4, K2HPO4 and CaCO3 was fermented by clostridium saccharo-butylicum a ; (2) as in (1) without K2HPO4; (3) a mash of 50 per cent hydrol and 50 per cent beet molasses containing grain alcohol distillery slop, and (NH4)2HPO4 was fermented by the same bacterium.  With a mixed mash as in (3), the fermentation may be started in the molasses and the hydrol-slop mixture added. Specifications 437,121 and 450,530 are referred to for information as to the bacteria clostridium saccharo-acetobutylicum a , b  and g . The Specification as open to inspection under Sect. 91 comprises also the addition of slop from butyl-acetonic fermentations with two examples illustrating it.  This subject-matter does not appear in the Specification as accepted.
