Title: Improvements relating to flexible joints and to methods of applying such joints to twin shackles or the like
IPC: B60G11/12
Filed: 1932-08-15
Abstract: 386,587. Shackle for laminated spring. TECALEMIT, Ltd., Great West Road, Brentford, Middlesex. Aug. 15, 1932, No. 22890. Convention date, Dec. 9, 1931. [Class 108 (iii).] In a joint, such as for a spring shackle, comprising inner and outer metallic sleeves with a resilient bushing between them and fixed to them, the inner sleeve is fixed to the shackle links by a right-hand threaded screw at one end and a left-hand screw at the other. This arrangement prevents relative movement of the parts and permits the use of hard metal for the bolts, which take the shear stress, while the sleeve is of light or soft metal with a high coefficient of friction against the shackle links. As shown, the outer sleeve 5 of the joint is fixed in the eye 4 of a laminated spring, and the inner sleeve 7 is fixed by left- and right-hand screws 8, 81 to the shackle links 1, 2 which are pivoted to the vehicle chassis 3. The rubber bushing is shown at 6.

Title: Electric resistance welding gun
IPC: B23K11/31
Filed: 1957-07-19
Abstract: 811,051. Welding by pressure. ALLAN, A. J., and BOOTH, P. H. July 19, 1957 [Sept. 10, 1956], No. 22943/57. Class 83 (4). An electric resistance welding gun comprises a plunger 11, for carrying an electrode 14, slidable in a guide member 10 and biased in one direction, a switch 25 mounted on the guide member for connecting the gun to a source of current, means on the plunger to engage a member. 29 to actuate the switch, a trigger 37 movable against a bias to actuate the switch and means 40 to render selectively the plunger and trigger inoperative to actuate the switch. Handles 13a, 13b extend from each side of the guide member, a cylindrical barrel, and the plunger in the barrel is connected at one end to a copper or brass ferrule 16 holding the electrode and bears at the other end against a spring 20 which urges the plunger against a stop 24 in the barrel. The tension of the spring is adjustable by a screw 23 in the barrel end cap. A micro switch 25 is mounted in the handle 13b and an operating arm 29 therefor is pivoted at 30 to extend through a slot 31 in the barrel into a recess 32 in the plunger. The trigger 37 is slidable in the guide member and engages a spring-loaded pin 39 in contact with the arm 29. A cam 40 rotatable by a lever 42 is mounted behind the trigger so that when the lever is in a position 45 a flattened cam portion 43 allows a locking pin 49 to be spring urged out of a recess 47 in the plunger but prevents movement of the trigger. In lever position 44 the locking pin is urged into the recess 47 and the flat 43 allows trigger operation. In lever position 46 both plunger and trigger are locked. In operation with lever 42 in position 45 the gun is pressed against the work to move the plunger against the spring so that a face 34 on the plunger engages the arm 29 to actuate the switch thus allowing current flow along the cable 35 to a carbon bush 36 contacting the ferrule 16. With the lever 42 in position 44 the gun is pressed against the work and the trigger is pressed to actuate the switch. The spring 20 may be dispensed with when compressed air is admitted to the barrel behind the plunger by a pipe 55.

Abstract: 1,261,748. Infra-red heating element. FUJI SHASHIN FILM K.K. 6 May, 1969 [18 May 1968], No. 23119/69. Heading H5H. To prevent a substantial area of the electrical heating strip '22 engaging the inside of heat resistant glass tube 21 on thermal expansion the strip 22 has at least one bent portion 23 intermediate its ends engaging the glass tube 21. Thus the bent portion or portions 23 absorb the thermal expansion and only the bent portion or portions of the strip engage the tube. 'The'bent portions may extend-on both sides of the ship as shown 'or on only one side 'thereof. The heat resistant tubes are made of quartz glass or crystalline glass. A plate heater was made from a plurality of glass tube heating elements of the type described above laid side by side with all the heating strips lying in the same plane, the glass tubes being cemented to transverse glass reinforcing tubes. The glass of the heating tubes consists of LiO 2 -Al 2 O 3 -SiO 2  with ZrO 2  added as a nucleii forming agent. An aluminium reflector plate was arranged on one side of the heating plate. The plate heater may be used in a surface heater or foot-warmer.

Title: Improvements in or relating to control systems for steam power plants
IPC: F01K13/02
Filed: 1957-07-22
Abstract: 850,476. Fluid-pressure servomotor-control systems. SIEMENS-SCHUCKERTWERKE A.G. July 22, 1957 [July 23, 1956], No. 23136/57. Class 135. In a control system for a steam power plant in which an hydraulic prime mover controller converts rotational speed variations of the prime mover into proportional pressure signals which are fed to a control circuit from which both steam generator and prime mover control signals are derived in parallel from a point in the circuit at which the pressure is dependent both on load variations of the prime mover and on independently controllable factors such as speed adjustment, the arrangement is such that upon occurrence of load variations and the consequent transmission of control signals to the prime mover and generator controllers, a further signal derived from the steam generator is superimposed temporarily on the prime mover control signal, so as temporarily to delay or reduce the controlling effect of the prime mover signal without affecting the generator control signal. By this means the comparatively slow response of the steam generator to rapid load variations is counteracted. In the system shown in Fig. 1 comprising a steam turbine 1 and boiler 12, pressure signals proportional to turbine speed variations obtained from a pressure converter 5 supplied by a turbinedriven pump 3 are fed to turbine and boiler controllers 9, 10 in parallel, a signal derived from the live steam connection 13 from the boiler being superimposed on the turbine controller 9. The latter controls a steam admission valve 11. In the arrangement according to Fig. 2, controllers 19, 20, 21 for the H.P. and L.P. turbines 33, 35 and the boiler 27 are provided, the superimposed control signal from a live steam connection 43 being applied to the H.P. turbine controller 19. For this purpose pressure from pump 3 is supplied to a bellows 17 with an operating rod 46 acting through a variable velocity ratio linkage 50, 51, 47 upon piston leak-off valves in the controllers 19, 20, 21 by which their output pressures are modulated. In the case of controller 19, the pressure in steam line 43 acts upon a regulator to impose the delay signal and thus modify the action of the leak-off control valve.
