Title: Improvements in burglar and like alarms for motor vehicles
IPC: B60R25/10
Filed: 1946-02-27
Abstract: 601,153. Theft alarms. RUNBAKEN, J. H. Feb. 27, 1946, No. 5045/45. [Class 118 (i)] [Also in Group XXXVII] In a car theft-alarm of the type in which tilting of the vehicle closes a switch fitted transversely across the vehicle, a visual testing means is embodied. When switches p and s are closed, tilting of the vehicle will tilt a switch d (see Group XXXVII) and so sound the hooter or the like r. In order to test the alarm switch d, switch p is opened and a test switch o closed, so that when the vehicle is tilted a lamp q will light, or a resistance in series with the lamp q will be short-circuited so that the lamp brightens. The switches p and o may be ganged together, so that when one is closed, the other is open. In order to cut-off the alarm completely, a nullifying switch s is opened.

Title: Method and apparatus for fabricating tapered tubing
IPC: B21C37/16
Filed: 1972-02-04
Abstract: 1386002 Making helically wound tubes; coiling; rolling L E EMBURY 4 Feb 1972 5364/72 Addition to 1276725 Headings B3A B3E and B3M [Also in Division F2] A method of making a tube comprises applying pressure to each edge of a flat strip in turn so as to impart alternating parallel curvature to the edge thereof in the plane of the strip helically winding the strip and joining the adjacent edges of the helically wound strip in abutting relationship thereby to produce a tube which alternately increases and decreases in diameter. In operation a longitudinal edge portion of a strip 170 is thinned to impart edge curvature in the plane of the strip by pinch rollers 368 and 508, Fig. 8, the roller 368 being biased at one end. The strip is then formed into a frusto-conical ring by rollers 324, Fig. 11, and roller 338, Fig. 3, and the ring centered by four rollers, e.g. 262A, Fig. 3 and 262D (324), Fig. 11, mounted at 90 degrees to each other. The leading edge of the ring being formed is abutted to the trailing edge of the previously formed ring by rollers 332 and 336, Fig. 11, and the two edges welded together by an electrode 172. The formed tube having a variable diameter is ground by abrasive belts and is supported by circumferentially, radially movable rollers mounted in housings 432, Fig. 2, 184 and 186, Fig. 17. The leading end of the tube activates a limit switch 592, Fig. 17, which actuates a cutting wheel 574 mounted on the housing 432. Engagement of the cutting wheel with the tube pulls the housing 432 along rail 198 until the housing activates a limit switch 570 which retracts the cutting wheel on completion of the tube cutting and allows a spring 572 to return the housing to a stop 568. In the embodiment shown in Fig. 2, a cutting torch 476 is used, the movement of the housing 432 towards switch 570 being effected by the housing rollers which are angularly positioned so as to be dragged by the tube movement, and the return movement of the housing being effected by a ram 232. Limit switches 584 and 588, Fig. 17, activate closure of the tube retaining rollers of housings 184 and 184, the latter switch also actuating a solenoid 546 to reverse the rotation of gear 542 and a template 178, the gear being driven, via a gear assembly 208 and a rubber coated wheel 510, by a wheel 504 driven by the pinch roller 368. The reversal of the movement of template 178 causes the closure of one of the air valves 558A or 558B by a plate 559. Air pressure is thus released from the opened valve to reverse the biasing of the upper pinch roller 368, the reversal of biasing causing a reversal in the gradient of the tube.

Title: Electro-acoustic transducer assembly
IPC: G01F1/66
Filed: 1975-02-11
Abstract: 1501756 Piezoelectric devices WESTINGHOUSE ELECTRIC CORP 11 Feb 1975 [25 Feb 1974] 5721/75 Heading H4J  An electro-acoustic transducer assembly 16, (Fig. 2), e.g. for use in flow meter or flaw detectors, comprises a generally tubular enclosure 22 having sealed thereto a transducer window 24 acoustically coupled to a piezoelectric element 28. Piezoelectric element 28 is acoustically coupled to an electrically conductive damping element 36. An insulating plug 38 fits around element 26. The insulating plug 38 is compressively held so that it acts to compress the damping element 36 against the piezoelectric element 28. This ensures maintenance of acoustic coupling and protection of the damping element 36 against damaging mechanical shock. As shown in Fig. 1 the assembly 16 is in position against a metallic vessel wall 12 such as the pressure vessel of an atomic reactor and is maintained in contact by a spring-loaded retainer 14 or by a magnetic coupling. In the assembly 16 the enclosure 22 acts as a conductive shield and this is connected to a stainless steel air-tight bellows 18 overlaid with a double braided stainless steel jacket and then to a housing 20 carrying a pot core transformer. The outer end of the enclosure has an hermetic seal 20 and two contact pins connected to the transformer secondary winding. The output conductors are terminated with a resistor which matches the impedance of the transducer assembly. The enclosure 22 (Fig. 1) is of nickel-iron alloy. Window 24 is a disc of the same alloy and is brazed to an alumina disc window 26 which in turn is brazed to a piezoelectric disc 28 of lead zirconate lead titanate. Alumina disc 26 is metallized on both surfaces by the moly-manganese process and is afterwards nickel plated. An annular terminal 30 is brazed to the disc 26 and a lead 34 is connected to it. The brazing alloy is of silver, copper and palladium. The damping element 36 is a graphite rod having an end in compressive contact with piezoelectric element 28 ground flat to provide dry acoustic coupling. The insulating plug 38 has a central aperture 50 through which passes a lead 43 connected to a terminal 44 abutting the conductive damping element 36. A forcing plug 52 is screwthreaded within the enclosure 22. A disc spring 57 or a number of disc springs mechanically joined in series extends between the plug 52 and an enlarged end 40 of the insulating plug 38 to hold the insulating plug 38 so that it acts on the damping element 36.

Abstract: 1,031,632. Fluid bearings. GEORGE RICHARDS & CO. Ltd. Feb. 6, 1964 [Feb. 12, 1963], No. 5750/63. Heading F2A. In a hydrostatic bearing, Fig. 1 (not shown), wherein high pressure lubricant is supplied from a source 18 through a pressure dropping device to the spacer 14, 15 between each pair of bearing surfaces, the clearance between the bearing surfaces is detected by the change in pressure in a small bearing pocket 26 and this change in pressure is arranged to adjust the pressure drop of lubricant supplied to one side of the bearing without adjusting the pressure drop of lubricant supplied to the other side. The pressure dropping device comprises a spool 17 slidable in a cylinder 16 and having a piston 22 acted upon by pressurized oil supplied from a source 27, and a piston 23 acted upon by pressurized oil branched from a line leading from the source 27 through a restrictor 28 to the pocket 26. In operation, should the pressure in the pocket 26 increase, thereby detecting a reduction in the upper bearing clearance, the pressure on piston 23 increases and the spool 17 is displaced to the right whereby lubricant passing through the annular space between the spool 17 and the cylinder 16 to the space 15 undergoes a reduction of pressure drop because of the decrease in the length of the annular space, whereas the pressure drop of lubricant supplied to the space 14 is unaltered. The pressure dropping devices may also be throats of adjustable cross-section.

Headings B8A, B8C and B8H. Bottles 5 are gripped by resilient grippers 3 which have portions 8 for clamping on an endless chain 1. Bottle-gripping arms 3a, Fig. 2 (not shown), are normally inclined inwards and a tension spring 9 may assist the gripping effect, Fig. 3 (not shown). The outer faces of upper arms 3b are engageable by frusto-conical discs 4 which are associated with each return wheel 2 for the chain 1. In operation, as the chain engages the wheel 2 above a feed conveyer 6, the discs 4 urge the arms 3b together and the gripper arms 3a diverge. The bottles thus enter the grippers, Fig. 2, and are gripped for transport as soon as the chain leaves the wheel 2. On arrival at a discharge conveyer 7, the gripper arms 3a are again caused to diverge and the bottles are released. When the bottles are to be transported in an inclined path, the interval between the grippers is increased and the speed of the conveyer 6 is made adjustable. A number of chains 1 with grippers 3 may be arranged side by side.
