Abstract: 947,091. Photo-electric sun tracking. NATIONAL RESEARCH DEVELOPMENT CORPORATION. May 11, 1962 [May 17, 1961], No. 18039/61. Heading H4D. [Also in Division F4] A solar heater, comprising a blackened and flattened tube 11 through which water or air as working fluid flows and is disposed along the focal line of a stainless sheet steel or sheet aluminium cylindrical parabolic reflector 12, is caused to home on to the sun by a scanning arrangement incorporating orthogonally-directional photo-electric receivers 32, 33, see also Figs. 3 and 4 (neither shown), mounted on a shaft to which crank 31, reflector 12 and tube 11 are connected. The photo-cells or phototransistors in receivers 32, 33 control respective motors 22, 27 to stop them when the sun is found, which is then tracked. Red filters may be used to remove interference from sky-or cloud-light. It may be arranged that, when the apparatus has homed on to the sun, motor 22 continues to run at a set speed to cause receiver 33 to follow the sun. The power supply to the motors may be switched on automatically by photo-electric or heat-sensitive means only when solar energy reaches a predetermined level. The reflector aperture may be covered by two nearby transparent and parallel sheets so as to enclose a layer of air, to minimize cooling of tube 11 by convection; and the transparent material reflects infra-red rays to reduce re-radiation from tube 11.

IPC: B23F23/10
Filed: 1920-07-02
Abstract: 146,459. Akt.-Ges. Brown, Boveri, et Cie. July 5, 1919, [Convention date]. Indexing.-To compensate for the errors in pitch.in milling or planing toothed wheels arising from inaccuracies in the dividing mechanism or other part controlling the movement of the work or tool, an additional neutralizing motion, 'based' on a curve representing the errors of. pitch, is imparted to the inaccurate detail. In compensating for errors in the worm wheel of a dividing- mechanism, the additional motion may be given to the worm wheel by moving the worm radially or axially with respect to the wheel or by varying the rotation of the worm. The radial movement may be given by mounting the worm b, Fig. 3, in occentric bushes l rocked by an arm k operated by an eccentric g or cam driven from the worm shaft at the speed of the worm wheel or at a speed corresponding to the cycle of errors. The rotation of the worm may be varied by means of a differential train, Fig. 10, interposed in the worm shaft, and having its frame rocked by an eccentric C. The Specification as open to inspection under Sect. 91 (3) (a) states that the axial movement may be imparted by lever q, Fig. 9 (Cancelled), driven by an eccentric or cam shaped to produce the desired corrections. This subject-matter does not appear in the Specification as accepted.

Abstract: 996,356. Hydro-pneumatic shock absorbers. STABILUS INDUSTRIEUND HANDELSGESELLSCHAFT m.b.H. May 14, 1962 [May 17, 1961], No. 18514/62. Heading F2S. In a method pressurizing the gas chamber 13 of a hydro-pneumatic shock absorber a peg 19 with a slot 18 is first introduced into a filling orifice 17 in a cover 16 of a cylinder 11 so that the upper end of the slot 18 projects outwardly above the cover 16 and then a cylinder 23, with a resilient insert 24 and having a plunger 27 mounted in its bore 25, is clamped against the cover 16 over the peg 19. Pressurizing gas, e.g. nitrogen with a small amount of a leak detector auxiliary gas, is then passed through a pipe 26 branched from the cylinder 22, through the slot 12 in the peg 19, and into the chamber 13. As soon as the gas in the chamber 13 has reached the desired pressure the supply of gas is cut off and the plunger 27 is moved downwardly either manually or automatically, e.g. by pneumatic, or hydraulic means responsive to the pressure in the chamber 13, to drive the unslotted part of the peg 19 home into the bore 17. The cylinder 23 can then be removed from the cover 16 and the top of the peg can be soldered, or burred over. The peg 19, which can be made of steel, non-ferrous metal, or plastics, may be uniformly conical, or cylindrical throughout. In a modification the orifice 17 is sealed by a ball which is fed through a slide leading into the bore 25 of the cylinder each time the plunger 27 is operated, the end of the plunger 27 being of concave shape to fit over the ball.

[Classes 65 (i) and 65 (ii)] A stay for hinged articles comprises a friction controlled pivoted arm 3, a swivel guide 9 and a buffer spring which serves as a stop to limit the amount of opening. The spring is adjusted by a nut 11. The arm is secured to a head 2 of a pivot pin and fibre washers 6 are disposed between the head 2 and the upper arms of a U-shaped bracket and between the bracket arms and a washer 7. These parts are pressed into frictional engagement by a spring compressed between the washer 7 and a collar 4, fixed on the pin, which bears on the lower arm of the bracket. The arm is secured radially to the pin 2 when the hinged movement is limited to one right angle. When an opening of two right angles is required the arm is secured to a lever of U-shape, the arms of which are pressed outwards by a spring between them into frictional contact with the U-shaped bracket.

Abstract: 455,244. Roller and roller-and-breast mills. COX, H. E., 131, City Road, Bristol. June 29, 1935, No. 18641. [Class 59] Adjusting mechanism for a mill having a spring - pressed roll or bar is provided with means for dead-setting or rendering the springs inoperative at any predetermined spring pressure within the limits provided which operate to pull or urge the movable roll or breast bar towards the co-operating roll. In Fig. 1, the movable roll 10 has its bearing block 9 encircled by a yoke 3 having one end 5 in contact with a spring 6 housed in a slotted cap attached to the block 9, the other end of the yoke being provided with a set-screw 7 on which the adjusting screw 4 bears, the set-screw 7 being adjustable in the yoke to abut against the block 9 whereby the spring 6 is rendered inoperative and the invention consists in adjusting the set-screw 7 in the yoke to provide a clearance 8 between the head of the set-screw and block 9 which determines the spring pressure at dead set position of the rolls. In a modification, Fig. 6, in which the rolls are forced together by the pressure of a spring 17 the screw 4 bears on a pin 18 and compresses the spring 17 in a housing 19 an the bearing block until the pin bears against a spigot 16 and thereby limits the spring pressure of the rollers at dead set position.
