Title: Improvements in and relating to stop devices for mechanisms
IPC: G07F15/00
Filed: 1952-04-21
Abstract: 735,566. Locking rotary elements. SMITH METERS, Ltd., and CHARLES, J. A. April 21, 1953 [April 21, 1952], No. 10030/52. Class 80 (4). A stop device for a rotary shaft 1, Fig. 1, comprises a sleeve 2 with a collar 3 secured to the shaft and a sleeve 5 mounted upon the sleeve 2 'for a certain amount of relative rotation thereto as allowed by a pin-and-slot coupling 7, 8. The collar 3 and sleeve 5 have radially projecting lugs 4, 6 thereon respectively with interengaging helical surfaces so that on movement of a control member 9 axially into the path of lug 6 the initial engagement thereof effects a relative rotation and axial movement of sleeve 5 into full engagement with the member 9 until the pin 7 engages the side of the slot 8 to stop positively the shaft 1. On removal of the control member 9 from the path of lug 6 the shaft 1 can again rotate and the sleeve 5 falls to its original position relative to sleeve 2 by gravity and/or spring pressure. In a modified arrangement shown in Fig. 4 applied to a gas meter prepayment mechanism a sleeve 10 secured to the shaft of a worm 20 which is to be controlled has a gapped flange 11 with which a disc 14 with axially extending parts 16 and inclined cam surfaces 17 co-operates. When a control member 27 is moved axially into the path of disc 14 the latter is first held and moved axially into full engagement with the member 27 until a shoulder 18 of the cam surfaces is engaged to stop rotation of the worm 20. The worm 20 is driven from the meter mechanism and drives the toothed planet carrier 21 of the quantity mechanism and then through a Geneva mechanism 23, 24 a cam 25 which operates a lever 26 carrying the control member 27. This lever may also actuate a gas supply valve, if desired. The worm 20 is released by the control member 27 on reverse movement of the cam 25 effected by the drive from the coin-holder on a prepayment being made.

Title: Improvements in refrigerating machines
IPC: F25B1/00
Filed: 1920-04-10
Abstract: 165,968. Baron, H., (Schwarzwaldwerke Lanz Kommandit Ges.). April 10, 1920. Refrigerating, compression machines for.-The driving-gear casing f of a small compression machine is arranged in the vessel m containing the evaporator coil d, the condenser b being arranged in a tank around the cylinders. The passage for the refrigerant slopes continuously from the top of the condenser coil to the bottom of the evaporator coil, which communicates with the interior of the gear casing at the bottom so that any refrigerant not vaporized in the evaporator, and oil entrained with the refrigerant from the compressor, flow automatically into the gear casing, where the refrigerant evaporates. A regulating- valve c is fitted between the condenser coil and the evaporator coil. The pistons a<1>, a<2> are driven from a main shaft g through a crank h, connecting-rod i and rocking arm k, the arrangement being such as to prevent wet compression by the splashing of liquefied refrigerant into the cylinders. In a modification the evaporator coil is located at the side of the gear casing; or two coils may be used, one surrounding the gear casing and one arranged at the side of it.

Title: Heat treatment of hot rolled steel wire rods
IPC: B21C47/26
Filed: 1970-03-03
Abstract: 1310934 Heat-treating steel wire WENDEL SIDELOR S A 3 March 1970 [5 March 1969 and 3 Sept 1969] 10137/70 Headings C7A and C7N Wire containing less than 0À15%C. is subjected to controlled cooling as it leaves the rolling mill, and is then isothermally transformed at 200-400C. In one type of apparatus, Fig.1, the wire is formed into overlapping turns 5 on conveyer 6 by laying head 3 and carried through enclosure (7) heated by burner 8 before being collected into coil 2, while in the variant of Fig. 2 (not shown), the wire is first formed into a coil on plate 10 and then lowered into chamber 11 for transformation. In further modifications the isothermal enclosure is heated indirectly by air or protective gas recycled through a heat-exchanger, or by heat radiated from a jacket. As illustrated in Fig.7 (not shown), wire leaving a conventional water-cooling operation is formed into turns 103 on conveyer 104 and undergoes air cooling to a minimum of 400C in zone 105. It then passes into isothermal enclosure 112 and is finally cooled in zone 113 by water sprays before coiling. The enclosure 112 is provided on its upper face with shutters 107 which are closed when wire is to be isothermally treated but may be opened to permit the apparatus to be used for the conventional cooling of hard steel wire rod as shown in Fig. 8 (not shown), in which form of operation the steel is initially air cooled in spaced vertical turns which are advanced by rack conveyers 122.

Title: Improvements in or relating to the passing of warp threads through reeds
IPC: D03J1/14
Filed: 1945-04-23
Abstract: 604,761. Threading reeds. ZELLWEGER, Ltd. April 23, 1945, No. 10202. Convention date, April 21, 1944. [Class 142 (ii)] Manual insertion of a warp thread 20 into the hook 33 of a threading device influences a feeler 45 which initiates the drawing of the thread through the reed 8 and the return of the hook through the next dent of the reed, where it remains until another thread is placed in position. The feeler 45 is carried by a bell crank lever 46 which, when the feeler is operated, withdraws a catch 51 from the path of a pawl 28 mounted on an eccentric 25, so that the pawl engages a motor-driven toothed wheel 21; the eccentric is thus rotated and, by means of follower levers 29, 30, imparts an oscillation to the hook 33, the parts being brought to rest again in the positions shown by the pawl 28 encountering the catch 51. The thread which has been drawn through the reed is removed from the hook by a rotating stripper 19 which deposits it on the outer side of a stationary disc 5. Insertion of the hook through successive dents is ensured by an arm 39, which swings with the hook 33 and a laterally bowed switch 34, which is attached to the hook and whose tip normally rests against the arm 39. The arm is beyond the hook as viewed in the Figure and is spaced from it by the width of one dent, adjustment being provided to cater for reeds of different pitches. When the hook swings anti - clockwise through one dent, the arm passes through the next dent and the switch 34 springs away from the arm in snapping past the reed wire separating the dents. On the return swing, the switch 34, being again in contact with the arm 39, guides the hook 33 through the dent occupied by the arm; when the arm emerges from the reed, the switch 34 pushes it into line with the next dent, the step-by-step movement as threading proceeds being followed up by the whole mechanism, which runs on rails 1. If movement of the hook 33 and arm 39 is arrested by the arm encountering a reed wire, an idle revolution of the eccentric ensues, the displacement of the lever 30 merely stretching a spring (not shown) which couples it to the lever 29. Insertion of the threads into the hook is facilitated by a guide hood 44 which, together with the feeler 45, can be swung to the position shown in chain lines to allow the reed 8 to be swung upright for removal.

Title: Method of determination of the mass and centre of gravity of an object
IPC: G01G19/00
Filed: 1974-03-08
Abstract: 1461195 Measuring the centre of gravity and mass of an object COMMISSARIAT A L'ENERGIE ATOMIQUE 8 March 1974 [19 March 1973] 10452/74 Heading G1A In a device for measuring the mass and determining the position of the centre of gravity of an object C; Fig. 2, at least one beam 1 or 2 of gamma or x-ray radiation (having a small cross-section dxdz or dydz compared with the object's dimensions) scans the object C. Each beam is received by a detector D 1  or D 2  whose output is then proportional to the attenuation of each beam. The attenuation is proportional to the mass of that part of the object in the beam's path. As the object is scanned the detector's output M (x, z)dxdz is passed through a processing circuit 20 Fig. 1, also Fig. 3 (not shown) to an integrator 22 for integration over x and z so that an overall value of the mass M can be determined. The detectors output is also directed via multipliers 24 or 26 to form the products zM(x, z)dxdz and xM(x, z)dxdz and thence to integrators 28, 30 whose output is divided by the value of the overall mass M by dividers 32, 34 to give the co-ordinates Z, X of the centre of gravity. A similar procedure is carried out in determining the other co-ordinate Y of the centre of gravity. One embodiment Fig. 1 comprises two sourcedetector sets arranged, as shown, on a frame. The frame is first moved, with respect to an orthogonal co-ordinate system OXYZ, so that with the arrangement is fixed with regards to one co-ordinate Z, while one beam (parallel to the OY axis) scans the object for all values of X. The detector's output is sampled and processed, if the scan is continuous, or, just processed if the scan movement is discontinuous. From these values the overall mass of the "slice" of the object thickness "dz" can be calculated by the circuit elements and the X co-ordinate of the centre of gravity of that slice determined. Next the process is repeated for a beam parallel to the OX axis to determine the Y co-ordinate of the centre of gravity. Thus by integrating the overall value M of the mass and the co-ordinates X, Y of the centre of gravity can be determined. The Z co-ordinate of the centre of gravity can be determined by integrating the function 2M(2). Each detector comprises a scintillator Fig. 3 (not shown) a photo-multiplier and a preamplifier and the detector's output passes via an amplifier an amplitude selector 54 and a logarithmic ratemeter to a differential amplifier 60 which also receives a reference signal proportional to "log I o " (the log of the intensity received by the detector if the object is absent). The output of the differential amplifier is proportional to the mass M of the object through which the beam passes. The embodiments may be used to investigate parts of the human body using radiation of a wavelength that is absorbed to the same extent by the different constituents making up the human body.
