Filed: 1930-10-07
Abstract: 354,111. Bowden mechanism. AMALGAMATED CARBURETTERS, Ltd. and TISDELL, T. A., Holford Works, Holford Drive, Perry Barr, Birmingham. Oct. 7, 1930, No. 29990. [Class 80 (iii).] A solid end-piece 2 of a handle-bar is formed with a groove 3 in which the terminal block 7 of the cable 8 moves. The abutment block 5 of the sheath 6 is fixed or secured adjustably in the groove. A projection 9 on the block 7 engages a helical slot 10 in a twisting sleeve 11 adapted to be mounted on the piece 2. The block 5 may also have a projection 18 adapted to engage a second slot 19 in the sleeve to increase the relative motion of the blocks. Alternatively the groove may be formed by recessing the handle bar itself. In a modified construction, Fig. 4, the abutment 5 has lateral lugs which engage a lateral slot 20. To allow of adjustment of the angular freedom of the sleeve 11 a recess 21, 22 is formed at one end of the piece 2 to house a wedge-shaped block 23 of hard rubber or the like. By turning a screw 24 the block is moved radially to regulate the frictional resistance to movement of the sleeve. Specification 352,334, [Group XXXI], is referred to.

Title: Dynamically terminated magnetic core memory line selection arrangement
IPC: G11C11/06
Filed: 1971-06-28
Abstract: 1349021 Magnetic storage arrangements ELECTRONIC MEMORIES & MAGNETICS CORP 28 June 1971 [29 June 1970] 30214/71 Heading H3 To pass a switching current pulse through a drive line selected from a group of drive lines in a magnetic storage matrix 20, the group of lines is initially charged to a potential V<SP>1</SP> by applying a charge current pulse from a charge pulse source 1a or 1b to the coupled sink ends 13 of the lines, and the drive end of the selected line LL1 is subsequently connected to a drive current pulse source 3a or 3b which acts in series with and assists the charge pulse source. Pulse sources 1a, 3a and 1b, 3b are operative for reading and writing, respectively, and in the inoperative condition both switches Q1a, Q1b are closed to maintain the group of lines at approximately earth potential. For reading, the pulse source 1a is operative, switch Q1a is opened and switches 2a, 4a are closed, the group of lines being then charged to a potential V<SP>1</SP> limited by a diode D2a biased by a potential Vs. Due to a connection with the charge current source through a bias resistor 7a the drive ends of the lines are subjected to a similar potential. Reflections in the lines are suppressed by characteristic impedances 8a and 9a. As soon as the drive lines are charged, and with the charge pulse source 1a still operative, a current pulse is produced through the selected line by the series assisting drive pulse source 3a. Reverse current through a selected line for writing is similarly obtained by using pulse sources 1b and 3b in conjunction with opened switch Q1b and closed switches 2b, 4b. Two groups of lines of which only one is operative at any given time may be interleaved, Fig. 4 (not shown), so that a selected drive line in a group has an adjacent line on either side at ground potential. The drive circuit may inelude the voltage stabilization circuit described in Specification 1,344,484 the circuit being connected in parallel with the characteristic impedances 8a, 8b, Figs. 1 and 2 (not shown).

Abstract: 793,783. Switching systems. GENERAL ELECTRIC CO. Oct. 21, 1954 [Oct. 27, 1953], No. 30352/54. Class 38 (4). [Also in Group XXXVII] A direct current relay whose energizing winding is connected through a rectifier to an A.C. source is dropped out by passing through its winding alternating current which flows through either a thermistor or a layer which separates the signal and heating conductors of an electricallyheated blanket which thermistor or layer is shunted across the rectifier and is normally electrically insulating to permit closure of the relay but at a predetermined change of temperature or humidity is sufficiently conductive to pass the alternating current necessary to drop out the relay. As shown in an indicating circuit in Fig. 3, which is in the operative condition, the relay 65 has its winding 66 connected to plug terminals 67, 73 through the rectifier 69 and relay holding contacts 71, the winding being energized initially by closure of a normally open starting switch 75 and maintained energized during non-conducting half-cycles of the rectifier by a shunting capacitor 74. Located where it is subjected to the temperature of the apparatus or device with which the circuit is to be used is the thermistor 76 which when subjected to abnormal operating conditions conducts alternating current, thereby dropping out the relay 65 which closes its contacts 77 to energize an indicator lamp 78. Applied to an electrically-heated blanket 4, Fig. 1, the heating circuit made via a control box 13 and plug-andsocket 8, 17 comprises conductor 18, the heating wire 5, conductor 19, the heater 24 contacts 20 and bimetal strip 23 of a cycling switch, and the contacts 21 of the relay 22. The relay winding 25 is energized, on closure of a normally open " ON " switch 33, by a D.C. circuit comprising rectifier 26, current-limiting resistance 27, signal wire 6, and conductor 29. Should the blanket become overheated at A the electrically insulating organic layer 7 separating the two wires 5, 6 becomes conductive, thereby permitting the alternating current to flow in the relay winding circuit and dropping out the relay. Should the blanket become over-heated at B the ensuing conduction of layer 7 reduces the relay winding current sufficiently to drop out the relay. In a modification, not shown, two D.C. relays are used. Specifications 703,813 and 705,844, [Group XXII], are referred to.

Abstract: 536,826. Vehicle fittings for loading. BURGESS, A. F. (Anthony Co.) Nov. 27, 1939, No. 30860. [Class 78 (iv)] [Also in Group XXXII] In vehicles in which the body moves rearwardly on the chassis and then tips to discharge or pick-up a load, an automatically-operated ground-engaging jack is forced downwards against the ground as the body begins to tip to form an additional support for the body during the tipping process. Fig. 1 shows a construction in which the piston of a hydraulic cylinder 7 is connected to one cross-bearer 16 of the body-frame. Admission of fluid to the left hand end of the cylinder, for example through the medium of a pump 8 driven by themotorofthe vehicle, also causes the jack foot 37 to be extended as shown in dotted lines and gives an initial tilt to the body about the axis of the rollers 30 by the riding of the cams 21 over the rollers 23 on the chassis. When these members disengage, further cams 24 engage rollers 25 and increase the angle of tilt. Finally the rollers 30 reach the forward end of the slots 29 and together with the jack form the support for the body during the rest of the tipping movement. The jack reaches the ground early in the tipping movement. A hydraulic circuit and arrangement of control valves for the mechanism is described. Discharge can be assisted by releasing the upper or lower end of the tail gate 18. In a modification for picking-up and setting down loads as a unit, the tail gate 18 is replaced by a load-support slidable in vertical guides. This rests horizontally on the ground when the body is tipped and the vehicle can be drawn away leaving the load stacked on the support. Fig. 8 shows a modification in which the body or the flat table 67 is fitted with a crane or derrick so that a container can be attached as shown in the full line position and swung to the dotted-line transporting position by the movement of the body.

[Class 110 (iii)] In a turbine with oppositely running rotors driving concentric shafts as for driving a torpedo, in order to avoid a torque produced by the reaction forces in the nozzles there are two sets of nozzles directed in opposite peripheral directions, the fluid from one set of nozzles impinging on the first ring of blades and that from the other set impinging on the second ring of blades. A further correction is produced by an inertia device which controls the relative supplies of fluid to the two sets of nozzles. The nozzles 14, 15 may be side by side as shown in Fig. 2, or, the nozzles 15 may be brought nearer to the second blade ring 11<2> as shown in Fig. 4. A free pendulum 19, Fig. 6, which remains vertical when the vessel carrying the turbine heels over, closes a part of one of the nozzle rings 14, 15, which merely for illustration purposes are shown in one plane, and so reduces the reaction due to those nozzles to regain the reaction balance. The part 20 extends over both nozzle ring widths and the solid pieces 21 in the two rings are staggered. Alternatively, the parts 21 are side by side and the effective edges of the parts 20 are staggered. Specification 570,624 is referred to.

Abstract: 744,568. Hydraulic couplings. BECKER, J. E. Nov. 9, 1953 [Dec. 2, 1952], No. 30989/53. Class 69 (2). In a coupling having freely rotatable outer and inner shells surrounding an impeller and a runner, any speed ratio is obtained by manipulation of brakes governing the speed of rotation of the shells. When the coupling is in driving operation, the outer shell 12, combined with a reservoir 16, the inner shell 17, the impeller 2 and the runner 18 are all rotating. To reduce the speed of the driven shaft 9, a brake 39 is applied and retards the shell 17 and fluid passes from the members 2, 18 through a check valve 27 into a passage 26 and to the reservoir 16. To return the fluid from the reservoir to the coupling, a brake 40 is applied and retards the reservoir, while an impeller wheel 37 secured to the driving shaft 4 maintains its speed. An increase of pressure in the fluid ring then causes fluid to pass from the reservoir through check valves 35 to a passage 36 and thence through orifices 44 to a passage 43 where it is carried centrifugally to the peripheral portions of the impeller and runner and passes between blades 29, 30 in the housings.
