Patent GB-2040069-A (GB)
Title: Apparatus for handling photographic negatives
IPC: B65C9/00
Filed: 1979-10-15
Abstract: The apparatus is for separating a photographic negative strip 12 from an adhesive layer 13 on a medium which is more flexible than the negative strip. It comprises a reel 18 for drawing the flexible medium over an edge 17 so as to alter abruptly the direction of travel of the flexible medium and thereby separate the negative strip from the adhesive layer. Collecting means 20 is provided adjacent the edge for collecting the separated negatives. Preferably, a deflecting surface 24 is provided which reduces the tendency for the negative strip to curl up on separation from the flexible medium and which assists in the collecting of the negatives in the collector. <IMAGE>

Title: >Focus indicator
IPC: G01S17/88
Filed: 1979-12-14
Abstract: The invention relates to a lens focus indicator. Two radiation sensitive detectors 4 and 5 are arranged adjacent to one another in the focal plane of a lens 1. Each detector provides an electrical signal of magnitude dependent upon the intensity of illumination to which it is subjected. An object to be focused is illuminated through the lens 1 by a beam of radiation which appears to originate from a point in the focal plane of the lens between the two detectors 4 and 5 and electrical signals obtained from the detectors are compared to indicate whether the object is in focus. The invention is suitable for use in the focusing of camera lenses. <IMAGE>

Title: Rotary mineral cutting apparatus
IPC: E21C25/10
Filed: 1980-03-11
Abstract: The apparatus comprises a shearer drum (18) having picks (22) and water jets (25) adjacent the picks. The drum is mounted on a hollow driven shaft (12) by means of a boss (16) fixed to the interior of the drum. The boss includes a central removable part (17) having a socket (35) for receiving water and passages lead to the jets from the socket through the boss and the drum. A supply conduit (40) is a push-fit in the socket and extends through the shaft (12) so that it can be removed from the goaf end. The conduit is rotatable with the boss and static seals are provided to prevent water leakage between the conduit and the boss in between the fixed and removable parts of the boss. At the goaf end, the conduit engages in a rotary seal (51) which can readily be replaced. <IMAGE>
Patent GB-2076603-A (GB)
Title: Radio Receiver Squelch Circuit
IPC: H03G3/34
Filed: 1980-05-21
Abstract: In a radio receiver which is continuously in an "ON" condition, in order to reduce power consumption a squelch circuit is employed to suppress any audio output in the absence of a received signal. The receiver has an IF amplifier 22 and discriminator 24 incorporating a resonant circuit normally tuned to the intermediate frequency. The output from the discriminator is proportional to differences between the frequency of the input signal and that of the tuned circuit and the resultant audio tone output on reception of a signal is used to switch the output stage 34 of the receiver ON. A tone filter 28 feeds a varactor diode whose capacitance is modulated by the output tone when an IF carrier is present. An audio output tone is produced by the quadrature detector 24 even if the IF carrier is unmodulated. Provided the gain and phase shift are correct through amplifier 26 and tone filter 28 the circuit becomes regenerative when an IF carrier is present and oscillation builds up at the tone filter frequency. The output from the tone filter is then used to unmute the output stage. A tone rejection filter 36 removes the tone from the audio output at 38, 40. <IMAGE>

Title: Reactivatable set-inhibited cementitious compositions
Inventor: SPENSLEY ROBERT HARDY
IPC: C04B28/06
Filed: 1982-12-08
Abstract: Aqueous grouting compositions based on high alumina cement have the onset of setting delayed for upwards of one month by the incorporation therein of a set-inhibiting agent such as boric acid or gluconic acid delta lactone and can then be rapidly reactivated for use by the incorporation therein of a reactivator, for example lithium carbonate, to produce a high strength hardened cementitious composition. The reactivated composition can advantageously be used to anchor a reinforcing element such as a rockbolt or dowel in a borehole and for this purpose the set-inhibited cementitious composition and the reactivator can be packaged in the separate compartments respectively of a dual-compartment frangible cartridge.

Title: In-vivo radiation counter
Inventor: POLLARD DAVID E
IPC: G01T1/167
Filed: 1981-09-25
Abstract: A radiation counter utilizing at least one detector (12) for sensing radiation from living body (14). The radiation counter also includes an aperture (32) for forming a corridor (38) between the body (14) and the detector (12). A shield (40) outside the corridor (38) prevents passage of background radiation through the corridor (38) and gaining access to the detector (12). The counter also includes a device (52) for isolating a selected portion of the body (14) from the corridor (38) such that radiation counting is restricted to a region of the body (14) through a separate detector (72, 74). The corridor (38) formation permits a user to stand in an upright position while the detector (12) and detectors (72 and 74) are able to separately monitor different sections of the body (14). The radiation counter overcomes the problem of obtaining accurate and quick measurements or radiation doses sustained by a large group of persons.
