Title: Automatic lifting device or jack for motor vehicles
IPC: B60S9/06
Filed: 1920-04-23
Abstract: 165,273. Baron, H. April 23, 1920. Stands or supports for vehicles.-Jacking- apparatus for raising motor vehicles comprises two screws which are connected to a common groundengaging member and carry nuts rotated through worm and spur gearing from the motor to raise or lower a framework connected to one of the axles of the vehicle. A worm 3 driven by the motor drives a worm-wheel 4 and a pinion 6 secured to the worm-wheel shaft 5. The pinion 6 drives a pinion 8 on a swivelling head 9 which can be moved angularly round the shaft 5 and fixed in position by a setting-and-retaining device 23. The head can be moved so that either of the pinions 8, 10 gears with a wheel 11 to rotate the nut 12 in reverse directions, or can be positioned intermediately so that neither pinion is engaged. The nut 12 is geared to the opposite nut 12a through the wheel 14. The setting and retaining device comprises a spring 20 fitted with a downwardlyprojecting stud 22 engaging notches on the framework. The latter is bolted to the vehicle axle at the points 2. Provision is made for disconnecting the power drive automatically when the nuts reach either end of the screws. For this purpose one screw is fitted with a groove furnished with stops 25, 26. At the end of the stroke a lug 27, Fig. 5, contacts with the stops and swings a plate 30 about its pivot 31, thus causing one or other of two horns 30a to raise a plate 21a. The plate is fixed on the end of the spring 20, which is raised thus to release the setting and retaining gear. The driving-torque then rotates the swivelling head 9 towards the disengaged position. During this movement the plate 21a is rotated away from the horns, and the setting-device re-engages at the disengaged position of the head.

Title: Improvements in or relating to synchronous clocks comprising a striking mechanism
IPC: G04C21/08
Filed: 1933-04-18
Abstract: 403,273. Electric clocks with striking mechanism. KINKHORST, H., 18, Mariaplaats, Utrecht, Holland. April 18, 1933, No. 11345. Convention date, April 18, 1932. [Class 139.] A single synchronous electric motor 2 drives both the time train and the striking mechanism and the member 15 which is adapted to lift the hammer(s) 14 of the striking mechanism is brought into cooperation with a wheel 11 continuously rotated by the motor. The latter drives the hands 3 and also a minute wheel 4 with two pins 5 coacting with a lever 6, 9 pivoted at 6<1>, the end 9 raising a double-armed lever 7 so that the latter releases the rack 8. The rack 8, thus released each half hour, falls an amount governed by a disc which is connected to the motionwork and has in its circumference slits and cams of unequal length. Rack 8 is linked by rod 23 to a lever 16, 17 pivoted at 16<1> so that as the rack falls the end 18 of arm 17 moves to the right, Fig. 1, whereby the cam face on end 18, Fig. 2, allows shaft 13 to be moved axially by spring 19 so as to bring arm 15 within the path of pins 12 or the constantly running wheel 11. Shaft 13 is rigid with hammer 14 and thereby effects striking. Rigid with wheel 11 is a wheel 10 with two pins which restore the rack upwards step by step as striking proceeds. To give the rack 18 ample time to fall its correct distance before striking commences slots 21 are provided in a peripheral flange of wheel 10. A resilient pin 22 on rack 18 has to pass through a slot 21 to the inner surface of the flange if the rack is to fall, and each slot 21 is directly behind a pin on wheel 10 so that the maximum time is given before striking commences.

Title: Process and apparatus for heat-treating granular material
Inventor: VANEY FRED DANIEL DE
IPC: F27B1/08
Filed: 1953-04-24
Abstract: 725,204. Automatic level control systems. ERIE MINING CO. April 24, 1953, No. 11371/53. Class 38 (4). [Also in Group XII] In a shaft furnace for indurating pellets of ore concentrates or fines, a substantially uniform stockline is preserved by control of the charging mechanism responsive to the position of a stockline feeler to maintain constant profile of the stockline, and by control of the discharge mechanism responsive to the position of the stockline feeler to maintain average stockline elevation. The charging mechanism comprises a rotary carriage 2 carrying upper and lower shoots 6 and 7 oscillated by a motor 9 through a reciprocating drive 8, and a feeler cup 32, which is pivotally mounted on a rocking shaft 34 in a bracket 35 secured to the carriage 2, and which precedes the shoot 7 as it rotates and oscillates according to the contour of the stockline. The lower shoot 7 tapers in width inwardly, so that pellets discharged over the edges are distributed evenly over the stockline, which may be horizontal or dimpled (Fig. 1). The carriage 2 is formed with a circular track 3 seating on rollers 4, and with a ring gear 17 meshing with a gear 18 driven by a motor 19. The discharge mechanism comprises an endless belt 30 driven by a motor 31. As the feeler cup 32 rides over hills 15a and valleys 15b, Fig. 3, in the stockline, it rocks an arm 40, and moves a slide 38 over the resistance 39 of a rheostat 36 to vary the speed of the motor 19 and hence the speed of rotation of the carriage 2 and the rate of charge deposition. The arm 40 also carries a mercury switch 42 by which a resistance 43 is switched in or out of the circuit of the discharge motor 31. When the feeler cup rides the stockline at or above the normal level 15c, the switch 42 will cut out the resistance 43, increasing the speed of the motor 31 and the discharge conveyer 30, whereas when the stockline falls, the switch will re-connect the resistance 43 and slow down the discharge conveyer 30. Conventional sliprings 54 and contact brushes 53 on the carriage 2 connect the switch 42 and rheostat 36 into their respective control circuits. In a modified control circuit, Fig. 4 (not shown), the rheostat 36 is replaced by two mercury switches and shunted resistances in order to provide the speeds " high," " normal " and " low " for the charging motor 19.

Filed: 1936-04-22
Abstract: A rubber adhesive or cement comprises a mixture of vulcanized and unvulcanized latex or like dispersion in such proportions that the mixture when dry is adhesive but exhibits the characteristics of vulcanized rubber.  The adhesive may be used in a single solution process, in which the parts to be joined, e.g. the sole and upper of a shoe, are coated with the adhesive, dried and pressed together, or in a double solution process, in which the parts, after being coated with the adhesive and dried, are treated with a rubber solvent or solution to revive the latex film. Sulphur, zinc oxide, and an accelerator, singly or in combination, may be added to the adhesive or to the solvent or solution or partly to one and partly to the other.  In an example, an adhesive comprises 5 pints of vulcanized latex of 50 per cent rubber content and 3 pints of unvulcanized latex of 30 per cent rubber content.  This may be modified, for a single solution process, by the addition of 2 oz. of sulphur, 3/4 oz. of accelerator and 1/2 oz. of zinc oxide.  For a double solution process, a vulcanizing solution may be used comprising 8 pints of trichlorethylene, 1/2 oz. of accelerator and 3/4 oz. of sulphur. Other examples are given.

Title: Methods of and systems for controlling vehicle wheel slip
IPC: B60K28/16
Filed: 1975-03-20
Abstract: 1497816 Controlling wheel spin ROBERT BOSCH GmbH 20 March 1975 [26 March 1974] 11586/75 Heading G3N Wheel spin in an accelerating vehicle is prevented by comparing the speeds of a driving and non- driving wheel on the vehicle and producing a pulse train whose frequency controls the engine torque which pulse train is interrupted when spin is detected and is resumed at reduced frequency for a preset time after the wheel spin condition has ceased. Preferably the pulse train is used as a clock pulse in the fuel injection system of the vehicle engine. In the arrangement shown, pulse trains on lines 40, 41 from the driving wheels pass through a 'highest wins' circuit 50 and a divider 53 to one input 56 of a comparator forming threshold stage 58 and pulse trains on lines 42, 43 from the non- driving wheels pass through 'highest wins' circuit 52 to the other input 57 of comparator 58. When wheel spin is present comparator 58 produces an output which passes through OR gate 72 and amplifier 66 and is used to inhibit the supply of fuel to the engine thus reducing the driving torque. In order to provide a reduced torque when wheel spin ceases the frequency of the pulses from the ignition contact breaker on line 32 is halved by bi-stable 81 and applied to NAND gate 77 together with the output from monostable circuit 68 which responds to the disappearance of the output signal from comparator 58. The circuit responds to inhibit alternate pulses to the fuel supply system for a period set by monostable 68 thus allowing the torque to be restored gradually to the driving wheels.

[Class 135] [Also in Group XXVI] Apparatus for controlling the supply of liquid fuel to internal-combustion prime movers has a variable choke 20 situated between an inlet 16 and an outlet 17 and adjusted by a barometric device 33, 34, a throttle 49 which is closed manually and opened by means 57 responsive to the fuel pressure, and means such as the diaphragm 45, responsive to the pressure difference across the choke to control the fuel pump 1 or a member such as a throttle or byepass valve regulating the delivery of fuel. As shown, the pump 1 is of the swash-plate type and its delivery is controlled by a spring-loaded piston 10, the two sides of which are connected by a restricted passage 13 and the movement of which is controlled by a vent valve 41 connected to the diaphragm 45 by a lever 40. The diaphragm 45 separates chambers 43, 44 connected by passages 48, 47 to the outlet 17 and a cylinder 23 respectively. The choke 20 is formed as a hollow plunger co-operating with a fixed conical member 21. The choke is rigid with a piston 22 in the cylinder 23. The passage 47 communicates with the inlet 16 through the cylinder 23 and a passage 24. The two sides of the piston 22 are connected by a restricted passage 27. The piston 22 is controlled by a vent valve 32 carried by a bellcrank lever 30, 31, the arm 30 of which is acted on by springs 35, 36 and by two capsules 33, 34. The capsule 34 is evacuated and the capsule 33 is open to atmospheric pressure. The lower spring 36 acts on the piston 22 through a stem 38. The throttle valve 49 is connected by a spring 25 to a lever 52 which is also connected by a spring 53 to the casing of the apparatus. The lever 52 is moved positively to close the throttle by a stem 56 and a manually-operated cam 55. The lever is moved in the opposite direction, when permitted by the cam 55, by means of a capsule 57, the interior of which is subject to a pressure dependent on the speed of the pump through a pipe 59 so that the throttle opens at a controlled rate independent of the rate of movement of the cam 55. Specifications 429,682, [Group XXVII], and 600,522 are referred to.
