Abstract: 1,118,130. Storage systems. CONSTRUCTIONS MILLS - K. 16 Dec., 1966 [20 Dec., 1965], No. 56520/66. Heading A4T. A storage device comprises a supporting framework of uprights (7, 8) and bracing members (5, 6, 9-13) for a. plurality of platform frames 1-4 which incline downwardly from the rear 14 to the front 15 of the device to gravity feed articles in files to the front of the device. Each platform is supported on the convex bearing faces 26 of brackets 23 hooked into selected slots 22-24 formed along the length of the uprights (7, 8). Further brackets 30, similar to the brackets 25, are hooked into selected slots 28, 29 in the side members 16 of the platform frames so that their convex bearing surfaces engage the rear walls of the front uprights (8) to act as stops preventing forward movement of the platforms. The platforms may carry T, L or I section rails with polished or plastics covered surfaces on which the articles are slidably supported. Alternatively the articles are supported on wheels or rollers carried by the platforms. A front end cross member 21 of the platform frame forms a stop to arrest forward movement of the articles. A hand operated ejector lever (71a, 71b, Fig. 17) may be mounted beneath the cross-member 21 to lift the leading end of the foremost article over the cross-member 21 to facilitate removal. Alternatively. the cross-member 21 carries a pair of outwardly projecting arms. (72; Fig. 18) supporting an adjustably inclined article receiving tray (75).

Title: Thermostatically Controlled Mixing Valve
IPC: G05D23/13
Filed: 1966-12-30
Abstract: 1,162,809. Valves. DANFOSS A.S. 30 Dec., 1966 [22 Jan., 1966], No. 58327/66. Heading F2V. In a thermostatically controlled mixing valve, closure of the cold and hot water inlets 2 and 3 respectively, is effected by means of bellows 19, 20 acting on a support 15 which is of hollow cylindrical form with lateral slots (17, Fig. 4, not shown) and carries at each of its ends valve closure members 11 and 12 for the two water inlets. The bellows is fixed to an annular plate 21, this plate being anchored to the housing 1 by two diametrically opposite arms extending from it, through the slots (17) and engaging recesses 23 in the housing. A pin 24 and weak spring 26 move the support 15, and hence the closure members, in response to deviations of the mixture temperature from the desired value as set by a control knob 28. Rotation of this knob results in an axial movement of a U-shaped coupling element 34 whose limbs 27 pass through apertures (38) in the end plate 13 of the support 15 and have recesses 39 which together with the end plate form a lost motion coupling. For a temperature range of between 30‹ and 40‹ of the mixed water, the thermostatic system alone acts upon the support 15 to maintain the mixed water temperature constant. To obtain water at below 30‹ or above 45‹, control 28 is rotated until one of the edges of recess 39 directly engages the end plate 13 and displaces the support accordingly, this allowing the hot and cold inlets to be completely shut off without using the thermostatic system. Reference has been directed by the Comptroller to Specification 1,078,995.

Patent GB-2019341-A (GB)
Title: Improvements in or relating to roller conveyors
IPC: B65G13/07
Filed: 1979-03-19
Abstract: A roller conveyor is provided in which the rollers are driven by resilient drive belts looped about the rollers and a drive shaft (10) that extends at right angles thereto. The tension in the drive belts is normally insufficient to transmit drive and tension is applied by a series of tensioning rollers extending parallel to the drive shaft and acting to apply pressure to respective groups of drive belts to produce driving tension therein. Each tensioning roller is supported on arms for pivotal movement away from its respective drive belts. Sensing rolls (50, 51, 52) are located between rollers intermediate each group of drive belts and have a surface proud of the rollers surface. Each sensing roll includes an operating arm (60, 61, 62) extending below and upstream of the rollers; an end portion of the operating arm acts against an arm of the tensioning roller acting on the drive belts of the next but one group upstream to cause that tensioning roller to pivot away from the drive belts in response to pressure exerted on the sensing roll by a stationary package, thereby causing the associated rollers to stop and preventing further packages being forwarded thus avoiding an undesirable build up of pressure between upstream packages. <IMAGE>
