Title: Apparatus for forming a profile frame
Inventor: KAUFERLE JOSEF
IPC: E06B3/673
Filed: 1982-12-14
Abstract: It comprises a profile shaping unit for shaping a continuous profile strand from a metal band, a punching device controlled as a function of the dimensions of the profile frame to be formed to form mitre recesses (84) in the locations corresponding to the corners of the profile frame to be formed, and means (90) for bending sections of the profile strand about axes oriented in the mitre recesses to form a closed profile frame. In a bending operation disclosed, the profile strand, held by a workholder (130), is fed to a driver (118) with a rotatable driving head (120) having a channel (122) to accommodate the leading end of the strand. Feeding the strand in direction B, the driver is simultaneously moved upwards on a guideway (116) so that the first section (124) is bent a right angles through apex (126) of the recess (84). With further feeding and reverse movement of the driver, the strand is similarly bent to form the frame. <IMAGE>

Title: Ground anchor
Inventor: WISE EDGAR GERALD
IPC: E02D5/80
Filed: 1983-01-05
Abstract: The anchor has earth-penetrating head 1 detachably connected to tubular driving-shaft 9. Tubular anchoring- element(s) 6 can pass through shaft 9. Load-bearing tendon or rod 4, secured to head 1, passes through element(s) 6. After insertion of head 1 into the earth, shaft 9 is disengaged and partly withdrawn from head 1. Ramrod 10 then forces the penetrating end 5 of element 6 against deflecting surface 3, thus directing end 5 outwards, perpendicular to tendon 4. This rotation of element 6 is permitted by virtue of opposing slots 8, which accommodate tendon 4 as the element is deflected. A series of elements 6 may be inserted, each being deflected by the preceding one in a different direction. <IMAGE>

Patent GB-880727-A (GB)
Abstract: 880,727. Transformers; selsyn machines; dynamo-electric machines having planar air gaps and printed windings. INDUCTOSYN Ltd. Feb. 18, 1958 [June 13, 1957], No. 5211/58. Classes 35 and 38 (2). In a position measuring transformer, to reduce stray coupling between the relatively movable primary and secondary windings caused by the return conductor of one winding, this conductor is duplicated and suitably disposed relative to that winding. The transformer may be of linear or rotary form and comprises two glass strips or discs on which are deposited closely spaced parallel conductors 54, 55. These are connected to provide a single winding on one member (the secondary), while on the primary they form two windings in quadrature. The two members are arranged face to face with the conductors in close proximity, the amplitude of the secondary voltage depending on their relative linear or angular position. It is shown how a single return conductor from the secondary winding forms a large single loop with the end connections of that winding and, being coupled with the primary, has an error voltage induced in it. To avoid this, two return conductors are provided 56, 63 adjacent the ends of the active conductors, and the current divides to cancel that in the end connections as shown in Fig. 11. Rheostats 43, 44 are provided to obtain correct division of current. 45 represents an indicating device or position correcting servo mechanism. The return conductors may alternatively be arranged on top of the end connections, separated from them by an insulating layer (Fig. 15, not shown). In the rotary form the active conductors are arranged radially on the discs, the end connections and return conductors being circumferential (Fig. 16, not shown). Specification 801,516 is referred to.

Filed: 1988-06-08
Abstract: An emergency speech communication system for use with a plurality of remote call stations (2). At each call station there is a call unit (1) having a call raising switch and sound transducer means. Transmission means (6) interconnect the call units with a master unit (5) for conveying data, control signals and audio signals between the master unit and each call unit. A personal radio transmitter unit (9) is associated with each call unit, and is operable to issue a call radio signal which is distinctive of its own call unit. A central radio receiver (41) is arranged to receive the call radio signal and is connected to a control unit (7), which responds to a received call radio signal to raise a call on the system in the same way as if the call raising switch of the call unit had been operated. A self-test arrangement provided in the control unit includes a timer operative to initiate a warning signal after a predetermined period unless re-set to zero within that period. A fixed radio transmitter (43) is triggered by the control unit at regular intervals to issue a test radio signal distinctive of the fixed radio transmitter. The control unit (7) is responsive to a received test radio signal to cause the timer to re-set to zero, and means are provided in the control unit responsive to the warning signal from the timer for initiating a warning call on the system indicative of a failure of the central radio receiver, in the event of the predetermined period expiring without the timer having been re-set to zero. <IMAGE>
