IPC: H02P7/285
Filed: 1967-07-05
Abstract: 1,150,825. Control of motors. STOP-MOTION DEVICES CORP. 5 July, 1967 [11 May, 1967], No. 31033/67. Heading H2J. [Also in Division D1] Depression of an inching-button 14 energizes solenoid 46 which closes contacts 48, 50, for activating the drive for a knitting machine. As the machine rotates, generator G provides an increasing voltage until transistor 110 is rendered non-conductive to de-energize solenoid 116 and open contacts 120, 122, in series with the solenoid 46. The generator G is shunted by a resistor 106 across which is developed a voltage, dependent upon the setting of voltage divider 90, and in opposition to the generator voltage. Adjustment of slider 100 therefore determines the amount of movement of the knitting machine resulting from actuation of the button 14. If the push-button is retained in the depressed condition, no successive movements of the machine are caused since solenoid 116 is short-circuited. If additional inching movement is required it is necessary first to release the inching - button. Continuous operation of the machine may be initiated by actuating starting-button 10 which energizes solenoid 46 as well as a holding relay 54. The drive motor is stopped by actuating pushbutton 16 or by activating a stop motion to energize solenoid 20. Actuation of a jog-button 12 energizes the solenoid 46 for the period that the button is depressed since there is no holding- circuit. Diode 74 prevents energization of the relay 54 under these circumstances.

Title: Improvements in and relating to the manufacturing of compositions
IPC: C08L61/14
Filed: 1935-11-11
Abstract: Moulded products are prepared by mixing a considerable excess of fibrous material, (such as wood meal, sawdust, wood felt, sugar cane, wood pulp, cork meal, asbestos, leather waste, textile fibres or pulverulent material) with an aqueous hardenable artificial resin composition and working up the composition in known manner.  The aqueous resin composition comprises an aqueous solution of an advanced stage phenol-aldehyde condensate that has been treated with an alkali metal hydroxide in which saponifiable fats, oils or wares or non-saponifiable fat-like substances are saponified or emulsified. The hardening of the product may be accelerated by the presence of alkali chromates, bichromate, manganese salts and metal oxides. Fireproofing agents such as phosphates, sulphates, chlorides, bromides, acetates, or water-glass may be added to the composition to increase the non-inflammability of the product.  To produce loose-structure slabs the composition may be treated with an aqueous metal salt to precipitate the resin as an insoluble metal salt and the composition shaped and dried.  In examples: (1) woodmeal is mixed with an aqueous solution of a sodium hydroxide derivative of a resin containing stearin or wool fat, the product is treated with ammonium phosphate solution and the composition moulded; (2) powdered asbestos is treated with an aqueous solution of a sodium hydroxide derivative of a resin containing colophony.

Abstract: 1514859 Supporting pipes CONTINENTAL OIL CO 27 July 1976 [29 Dec 1975] 31267/76 Heading F2P [Also in Division B8] A flexible slurry carrying hose 55 extending between a fixed point and a movable mining apparatus 59 comprises an overhead monorail 10 along which hose supporting beams 18 are movable on support systems 14 rollably supported on the monorail 10, the beams 18 being pivotally mounted on the support systems 14 whereby they move into positions transverse to the monorail 10 as the hose bunches up into horizontal loops to take up slack in the hose. Each beam 18 incorporates three longitudinally spaced double clamps 50, 51 for supporting three parallel hoses 55, 57 each clamp being pivotable relative to the beam and the two outer clamps also being longitudinally slidable permitting the hoses to form smooth loops. Each support system 14 comprises monorail rollers 20, brake arms 25 spring biased into braking engagement with the monorail 10 and pivotable into their release position by cams 43 on an outer shell 30 rotatably mounted on an inner mount 37 carrying the rollers 20 and brake arms 25. The outer shell 30 is secured to and therefore rotatable with the beam 18, whereby as hose is pulled out from the bunched configuration each beam 18 in turn is pivoted causing release of the support system brake upon sufficient rotation of the beam 18. Apertures in the inner mount 37 and the outer shell 30 are aligned so that dogs 41 secured to a cable 40 can freely pass therethrough until the beams 18 become aligned with the monorail 10 where a dog 41 is locked to each support system. This permits the support systems 14 to be hauled in by the cable 40 when the apparatus, Fig. 9, is moved to generate slack in the hoses, until rotation of each beam 18 causes release of the associated dog.

Title: Improvements connected with camera shutters
IPC: G03B9/22
Filed: 1931-11-12
Abstract: 397,103. Photographic shutters. GOSSEL, M., LUDWIG, (nÚe GOSSEL), A., GOSSEL, C., and LUDWIG, L., (trading as GOSSEL, P.), 10, Heidenauer Strasse, Dresden, Germany. Nov. 12, 1931, No. 31402. Convention date, Nov. 13, 1930. Void [Published under Sect. 91 of the Acts]. [Class 98 (i).] For " time " and " bulb " exposures the shutter is operated directly from the operating lever 13, Fig. 1, through a lever 48 provided with a notch 49 adapted to engage a pin 50 on the shutter ring 51. When set for " time " exposures, a shoulder 60 on an auxiliary lever 52 drops behind the pin 50 and retains the shutter open ; during its return, the lever 48 moves outwardly upon the pin 50, and a spring latch 54 thereon engages behind a pin 57 on the casing ; upon a second operation of the lever 13, the pin 57 causes the end 53 of the lever 48 to engage the hooked end 58 of the lever 52 to release the pin 50 and allow the shutter to close. In the " bulb" position, a cam 59 on a setting ring 46 deflects the lever 52 so that the pin 50 is not engaged by the shoulder 60. When set for instantaneous exposures, the lever 48, Fig. 5, is rendered inoperative by a shoulder 62 on the lever 52 which is further deflected by a second cam 61 on the ring 46. For instantaneous exposures, the shutter blades are operated by a spring drum 7 which is locked in unwound position for " time " and " bulb " exposures by a lever 45 movable into and out of engagement with a notch 44 on the drum by a third cam surface 47 on the ring 46. The drum is held in set position by the end 10, Fig. 4, of a lever 15 engaging a notch 11 in the drum, and is released by an arm 14 on the operating lever 13 tripping the lever 15. A cam 5 on the drum operates the shutter blades through a lever 3, 4, which is set to regulate the exposure. The release of the drum 7 may be delayed by an escapement mechanism 28 .. 36, which is normally held inoperative, as shown in Fig. 4, by a pin 22 on a friction-held lever 24 engaging a clutch lever 19. In the operative position, Fig. 5, the lever 19 lies in the path of a projection 16 on the drum 7 and, as the drum is wound, the lever 19 is rocked together with a lever 26 carrying a sector 27 which winds the pinion 28, the mechanism being held in the wound position by a detent lever 38 engaging the sector 27. When wound, the release lever 15 moves out of range of the arm 14 which now engages the end 41 of the lever 38. Upon operation of the escapement, a cam 39 on the pinion 38 trips the lever 15 to release the drum 7. In the inoperative position, Fig. 4, the lever 15 moves the escapement 36 into an inoperative position through a member 43.
