Abstract: 1,266,673. Antiskid brake mechanisms. AISIN SEIKI CO. Ltd. 9 March, 1970 [8 March, 1969; 5 April, 1969], No. 11272/70. Heading F2F. An antiskid brake control mechanism in an hydraulically operated vehicle braking system comprises a first pneumatic servo mechanism 38 having a diaphragm piston 41 establishing two variable volume chambers 38a, 38b in the mechanism 38, a check valve unit 78 actuable by movement of the diaphragm piston 41 and intended to allow or cut off hydraulic flow between a master cylinder 31 and rear wheel brake cylinders 18, a second servo mechanism 19 having a diaphragm piston 21, 22 establishing two variable volume chambers 11a, 11b, a plunger 12 actuable by movement of the diaphragm piston 21, 22 to increase or decrease the volume of the connection between the master cylinder 31 and the brake cylinders 18, the servo mechanisms 38, 19 being operated by a changeover valve unit 50 on receipt of an electric signal from a skid sensor 66. As shown in Fig. 1, chambers 38a, 38b and 11b are normally connected to a vacuum source 46 and chamber 11a is connected to atmosphere via valve unit 50. In a braking action and upon a skid being sensed a signal is sent from sensor 66 to a solenoid coil 64 of the valve unit 50, this causes movement of a hollow plunger 59 to connect chambers 38b and 11b to atmosphere and chamber 11a to vacuum source 46. Pressure differentials are thereby established on either side of the diaphragm pistons 41 and 21, 22: the diaphragm piston 41 moves to the right to close valve unit 78 by movement of a valve member 26 and thereby break off hydraulic connection between the master cylinder 31 and the cylinders 18; the diaphragm piston 21, 22 moves to the left to thereby move plunger 12 so that the increasing volume causes the pressure at cylinders 18 to be relieved, and the brakes taken off. As shown in Fig. 2 the chambers 116<SP>1</SP> and 386<SP>1</SP> are interconnected by a duct 101 for the simultaneous admission of atmospheric pressure to both upon a skid being sensed.

Abstract: 1287823 Automatic control WERKZEUGMASCHINENKOMBINAT FRITZ  HECKERT KARL-MARX-STADT VEB 27 Feb 1970 9620/70 Heading G3R A control arrangement, preferably for machine tools in which a measured parameter has a superimposed disturbance due to non-concentric mounting of a workpiece, comprises, Fig. 1, a comparison stage 1, in which the measured parameter X is compared with a desired value W, followed by an intermediate stage 2 having a threestate switching characteristic of a bi-directional polarizing relay. The output of the intermediate stage are a logic L on a line 3 when X is less than W-a (a dead-zone value) and a logic L on a line 7 when X is greater than W + a and are fed back through a delay member to the comparison stage and over lines 3, 7 to a stage 4 and a setting stage 6 which determines the operation of a control path R. The stage 4, Fig.2, receives the L signal on line 3 and through a synchronizing contact 8, actuated by a cam 10 on a machine spindle, feeds it through a pulse-divider 9, at half-rate, to a bi-stable device 11. Restoring inputs of divider 9 and device 11 responsive the O signal on the line 7 through a negator 12. The output of device 11 is fed to an AND-gate 15 together with direct L-signal from the line 3. The output of the AND- gate is fed to the setting stage 6. The stage 4 operates so that L-signals on line 7 are always effective and L-signals on line 3 only during the operation of the contact 8 so that the measured parameter tends to be maintained at the maximum actual value irrespective of the superimposed disturbance. In a modification (not shown), the restoring inputs of pulse divider 9 and device 11 are directly connected to line 3 and the AND-gate 15 eliminated.

Abstract: 1308455 Radio transmission of alarm condition T C MORRIS 7 May 1970 [7 May 1969] 23378/69 Headings G4H and G4N In a burglar and/or fire alarm system, the alarm condition is transmitted by radio from a sub-station to a central station by means of a pre-recorded message on a tape recorder with staggered sound heads, The detection circuit x and y, pass a current, which holds relay A in the open condition. If an alarm condition occurs the contacts 10 close shorting out the detection circuit, causing a momentary high current to pulse to pass through relay C which activates the tape recorder and transmitter units. The relay contacts 10 are then opened as the shorted current flows through the relay coil. Contacts 13 are also operated by relay A to select a track on the tape recorder indicating that the alarm condition is a burglar alarm condition. The fire detector operates in a similar manner via relay B. When the alarm is actuated, a mechanical switch 15 is driven by the spindles of the tape recorder deck, so that about a minute after the alarm signal has been initiated the switch automatically stops the transmission. In another embodiment an audio alarm at the sub station is also provided.

The indicia may be applied to the carrier by printing with an ink which contains a precursor for a urethane polymer, which is subsequently caused or allowed to become converted to the polymer. Prior to use, the adhesive of the transfer may be covered by a protective sheet. Two support films may be present, one over and one under the indicia, with which they transfer. A polymer film which forms the uppermost layer of the carrier sheet may be made to separate from the remainder of the carrier sheet and cover the indicia on a receiving surface.

The gas emerges vertically from the apertures 14 thus producing a lifting effect on the articles while it emerges inclined in the direction in which the articles are to travel from the apertures 12, thus moving the articles. In motion the articles are guided by rods 8 whose lateral position relative to the surface is adjustable. In an alternative embodiment, Fig. 5 (not shown), the chamber is divided into three sections by partitions (22, 23), each section having dampers (24-26) controllable by handles (27-29) such that the lifting thrust from the apertures 14 can be controlled independently of the propulsion thrust from the apertures 12.

Title: Clad composite stent
IPC: A61F/
Filed: 1994-01-13
Abstract: A body compatible stent is formed of multiple filaments arranged in at least two sets of oppositely directed helical windings interwoven with one another in a braided configuration. Each of the filaments is a composite including a central core and a case surrounding the core. In the more preferred version, the core is formed of a radiopaque and relatively ductile material, e.g. tantalum or platinum. The outer case is formed of a relatively resilient material, e.g. a cobalt/chromium based alloy. Favorable mechanical characteristics of the stent are determined by the case, while the core enables in vivo imaging of the stent. The composite filaments are formed by a drawn filled tubing process in which the core is inserted into a tubular case of a diameter substantially more than the intended final filament diameter. The composite filament is cold-worked in several steps to reduce its diameter, and annealed between successive cold working steps. After the final cold working step, the composite filament is formed into the desired shape and age hardened. Alternative composite filaments employ an intermediate barrier layer between the case and core, a biocompatible cover layer surrounding the case, and a radiopaque case surrounding a structural core.
