Filed: 1974-04-09
Abstract: 1421695 Range finders C E KESTER 9 April 1974 [19 April 1973] 15753/74 Heading G2J A short home base range finder of the coincidence type includes a flexible tape T which carries a graduated scale G and moves past a fixed reference mark on operation of a control knob 54, 55 to bring the two images seen through an eye-piece 22 into coincidence. The appropriate object distance is read from the scale G through a window 90 in the rangefinder housing. The control knob 54, 55 is coupled to a mirror 40, rotating it about a pivot 34. Both ends of the tape T are wound on adjacent zones of a cylindrical surface 60 which forms an integral part of the control knob portion 55. An idler spool 80 takes up slack in the tape as the knob is rotated. The two parts 54, 55 of the control knob may be axially separated in order to effect an initial adjustment of the tape T without moving the mirror 40. The pivot 34 may be moved along its axis to pivot the mirror 40 about a line defined by two bearing points 29 and so adjust the vertical alignment of the observed images.

Title: Improvements in electrical step-by-step mechanism
IPC: H02K7/065
Filed: 1925-06-19
Abstract: 258,022. Parsons, I. H., and Ball, A. E. J. June 19, 1925. Reciprocating and oscillating machines.- In a clock wherein the minute hand is advanced step-by-step by electromagnetically - operated ratchet mechanism the ratchet wheel is partly protected by a guard and the driving pawl works between light rods or check springs arranged at an angle preferably of 45‹, to the path of the pawl. The ratchet wheel A of metal, fibre, or the like is either mounted on, or geared to, the minute hand spindle and is rotated by a wire pawl B pivoted at B1 to the armature lever B4 of the magnet H. A guard plate D constrains the movement of the pawl B and masks the ratchet wheel so that only a few teeth thereof are exposed at any one time to the action of the pawl. The movement of the driving pawl is also limited by two wire spring arms E, F; C being the usual pawl preventing retrograde movement of the wheel A. B6 is a right-angled arm on the part B co-acting with a fixed pin B7 to keep the pawl engaged with the wheel. In a modification a ratchet wheel having twelve teeth is operated from an armature which is centrally pivoted and oscillates between the two poles of its magnets. In a further modification the armature is of wire and is slidably adjustable upon its central supporting member. In another modification a single wire is bent to a triangular shape to constitute the two check springs and the guard.

Title: Improvements in electric thermostats
IPC: G05D23/24
Filed: 1935-05-31
Abstract: 451,141. Automatic control systems. GENERAL ELECTRIC CO., Ltd., Magnet House, Kingsway, London, and WESTELL, E. P. L., c/o General Electric Co., Ltd., Coventry. May 31, 1935, No. 15876. [Class 38 (iv)] Temperature.-The input of an amplifier is connected to one diagonal of a Wheatstone bridge and the output to the other so that when in balance no oscillation. occurs. Means causing a current variation according to the state of oscillation of the amplifier caused by a degree of unbalance of the bridge control an element supplying heat to the space containing the bridge to maintain its temperature constant. The bridge may itself comprise the heating element. The anode circuits of two thermionic valves 15, 25, Fig. 4, are connected through the windings of a relay 21 so that their energizations under normal conditions balance. The valve 15 has its grid circuit connected through the transformer 12 across the diagonal 4, 41 of the bridge 1 subject to the temperature of a heated space 11 and the output of valve 25, which amplifies the output of the valve 15, is connected through the transformer 52 to the other diagonal 6, 6<1>. When the bridge temperature falls sufficiently the compling through the bridge is adequate to establish oscillation and the relay 21 becomes unbalanced so that the contacts 38 are closed and heating current is supplied to the resistance 36 to raise the temperature. The valve 15 is at the same time rendered more susceptible of oscillation with a view to avoidance of hunting by a change in grid bias caused by the winding 34 of the transformer 52. The connections shown provide for the application of D.C. to the bridge and an instrument 56 measures the D.C. out of balance current and acts as a distant reading thermometer. It may also act as an alarm or safety device if a wide departure of temperature occurs. Fig. 3 shows a form in which the bridge is at the same time the heating means for the space 11 the output of the valve 25, supplemented if required by alternating current supplied over the impedances 44, 45 from the source 37, traversing the bridge 1. The invention is not applicable to cases where temperature deviations in both senses may occur.

Abstract: 580,487. Fluid-pressure servomotorcontrol systems. LUCAS, Ltd., J., IFIELD, R. J., and NICOLLS, W. E. W. Sept. 29, 1943, No. 16000. Addition to 577,016. [Class 135] In a variable output pump of the swash plate type as described in the parent Specification, the valve which provides the restricted passage between both ends of the servo-cylinder and which, when actuated, allows the pump to operate as a constant delivery pump, is loaded by fluid pressure as well as by a spring. As shown, the valve 5<1> abuts against or is connected to a piston or diaphragm 12<1> loaded by a spring 15<1> and by air pressure supplied through a passage 14<1> from a blower driven by the prime mover fed by the pump. The delivery pressure from the pump acts on the diaphragm through a passage o, and when this pressure falls below a predetermined level communication between the conduit o and the left-hand end of the servo-cylinder is cut so that the spring m<1> will force the piston k<1> to the left to move the swash plate of the pump to its maximum setting. In a modification, the passage 16<1> is omitted, the passage o leads into the chamber 41 which also communicates with the chamber 10<1>, and the passage o<1>, which leads only to the sump, is put into communication with passage p<1> when the valve is actuated.

Title: Improvements in and relating to sheet-fed offset lithographic printing machines
Inventor: KING CARL GUSTAVE
IPC: B41F13/28
Filed: 1953-06-10
Abstract: 737,513. Printing-machines. ROTAPRINT, Ltd., [formerly KAYES ROTAPRINT AGENCY, Ltd.]. May 28, 1954 [June 10, 1953], No. 16046/53. Class 100 (2). Tripping-arrangements.-In an offset lithographic machine means is provided whereby when the offset cylinder is tripped relatively to the impression and printing cylinders the sheetfeeding means can be rendered operative by the actuation of a hand-lever or foot-pedal so that sheets can be fed through the machine for test &c. purposes without the necessity of removing and remounting the printing-plates. As shown, the shaft on which the offset cylinder 2 is rotatably mounted has eccentric ends 4 mounted in the machine frame, one of which has secured thereto a support 5 having two links 6, 7 pivoted thereto. The links are connected by a crosslink 8, and an arm 9, secured to the link 6, carries a roller 10 which co-operates with a fixed plate 12 having arcuate abutment surfaces 13, 14. A lever 15, pivoted intermediate its ends to the arm 9, has a hook-nose 16 adapted to engage a shoulder 19 on a cam projection 18 on the cylinder 2, and a tail 17 provided with a stud 17a adapted to be engaged by a lever 22 which is rigid with a link 21 pivoted to a pushrod 20. Before printing, and the rotating cylinder 2 not in contact with the rotating forme and impression cylinders 1, 3, respectively, the push-rod 20 is depressed to the position shown so that the lever 22 forces the nose 16 of the lever 15 to engage the shoulder 19 on the cam 18. As the cylinder 2 rotates, the lever 15, attached links, and eccentric shaft end 4 are carried round with the cylinder to a position where the roller 10 engages the first arcuate surface 13, and the tail 17 of the lever 15 strikes a stop 24 to cause the nose 16 to leave the shoulder 19. A tension spring 23 now pulls on the links to cause the roller 10 to enter the second arcuate surface 14; in this position the cylinder 2 now contacts the cylinders 1, 2 for printing. The sheet-feeding means is driven by a gear 24, loosely mounted on the shaft 3a of the impression cylinder 3, adapted to be driven with the cylinder 3 when a lug 27 on a pawl 25 pivoted on the gear engages a notch 28a in a member 28 secured to the shaft 3a. Normally, with the cylinder 2 tripped-off, a slidable bar 29 prevents such engagement, the bar being slotted at 30 to engage over a pin 31 on the member 5; but when the push-rod 20 is depressed, the member 5 rotates to withdraw the bar 29 to allow the sheets to be fed. To allow the sheets to be fed with the cylinder 2 trippedoff, one arm 32a of a bell-crank lever pivoted at 32 is pivoted at 33 to the bar 29, so that hand or foot pressure exerted on the other arm 32b slides the bar to allow the lug 27 to engage the notch 28a; the slot 30 ensures that the member 5 is not moved by this operation. Specifications 728,737 and 729,548 are referred to.
