Patent GB-2069934-A (GB)
Title: Processing panels etc.
IPC: B44F9/04
Filed: 1980-02-09
Abstract: To produce a stone effect on a surface area of a panel or the like, striations are produced in the area by scoring. The scoring may be by use of a scoring tool, e.g. a wire brush, or blasting, and may be manual or by a machine comprising scoring means and means to effect relative movement between the member and the scoring means. Fine scoring may be preceded by cutting or coarse scoring. The member may comprise felted mineral wool fibre, and may be a whole, broken or damaged ceiling panel. It may be hardened after scoring and used as a master for moulding. Comminuted reflective material may be deposited at the surface. In the machine, the wire brush may be rotary, the wires may be long enough for random sideways motion and may have an irregular profile, the movement means may provide irregular movement, and/or reciprocatory sideways and/or normal movement, the scoring means may comprise a plurality of scoring units which may execute mutually different movements. Simulated stonework is produced by adhesively affixing the members directly to a foundation or affixing them to a perforate member, e.g. as "crazy paving". <IMAGE>

Title: System for scavenging and charging the cylinders of a two- stroke internal combustion engine
IPC: F02B25/04
Filed: 1980-02-15
Abstract: The cylinder head 3 is formed with two circular rows of air or mixture inlet ports 7 distributed uniformly and concentrically with the axis of the cylinder over the cross- section. The inlet ports 7 are closed by an intermittently moved valve slide 11 or respective valve slides (24), Figs. 4 to 9 (not shown), which are movable over a surface of the cylinder head facing the combustion space and biased into engagement with the surface. As a result of the uniform distribution of the charge entering the swept space (1) of the cylinder, a longitudinal advancing "displacing piston" of charge is formed which expels the combustion gases through piston-controlled exhaust ports (5), to provide optimum scavenging. <IMAGE>

Title: Method of and apparatus for detecting range pulses for distance measurement
IPC: G01S7/28
Filed: 1980-06-02
Abstract: In a radio distance-measuring system the received pulse is amplified in a logamp LA and demodulated to derive a unidirectional pulse which is applied to two threshold devices A1 and A2 set at different levels. The transit time interval between the crossing, by the leading edge of the pulse, of the two thresholds is timed by a timing-ramp voltage generated by two constant-current generators CC2, CC3 and a capacitor C2. The timing ramp, which appears at point g, is started when the lower threshold is crossed and its slope decreases when the upper threshold is crossed; the arrangement is such that irrespective of the strength of the received pulse the ramp reaches its final voltage at a given point, for example half-height, on the leading edge of the pulse, at which point a signal appears at an output Q of a flip-flop FF controlled through an amplifier A3 by the timing ramp at g. <IMAGE>

Patent GB-2073048-A (GB)
Title: Grinding methods and apparatus
IPC: B02C19/18
Filed: 1980-08-13
Abstract: The size reduction of plastics, rubber, or other materials is effected with reduced consumption of a cryogenic fluid such as liquid nitrogen by introducing the materials to be ground into a hopper 16 and supplying a liquid cryogen from a conduit 37 to the throat 17 of the hopper 16 which is disposed in communication with a standpipe 18. A screw conveyor 20 is provided for metering chilled material, equilibrated in temperature, from the exit of the standpipe into a grinding mill 22 where such material is reduced in size. Temperature control means are preferably provided so as to sense the temperature existing in the hopper throat to enable the flow of liquid cryogen thereto to be controlled. By passing chilled materials through the standpipe 18, sufficient time will elapse to enable a temperature equilibration of the materials and, thus, enable grinding thereof with less energy and hence less heat generated by the grinding device which in turn requires less, if any, additional flow of liquid cryogen to the grinding mill 22 and hence minimises the consumption of such cryogen. <IMAGE>

Patent GB-2077457-A (GB)
Title: Measuring deformation living cells
IPC: G01N21/47
Filed: 1981-06-04
Abstract: The invention relates to a method and device for measuring the deformability of living cells, notably of red blood corpuscules, which permits valuable indications to be obtained on the quality of the hemoglobin and the structure of the wall. In order to produce easily a deformation in a cell population enabling the production of an optical diffraction pattern, a liquid containing a suspension, either homogeneous, or localized, is passed into a transparent tubular channel with a fixed wall in the form of a laminar flow, the beam passing through this channel perpendicularly. This method avoids the use of movable mechanical means for obtaining the conditions necessary for the deformation of the cells. Blood cells are injected into an annular flow 27 stabilised by fluid from 30 and 31. A system using a laminar channel is also disclosed (Figure 1). <IMAGE>

Filed: 1982-02-04
Abstract: The brake comprises a pivotal support (4) for the two ends, remote from a floating pressure-applying device, of a primary brake shoe (1) and secondary brake shoe (2) the support (4) providing a fixed abutment during forward travel braking and deflecting towards the end of tie primary shoe against the action of a spring (8) during rearward travel braking, the pivotal support (4) supporting the end of the secondary shoe so that the distance during rearward travel between the ends of the shoes is reduced. Two abutments (5, 6) fixed to the brake back plate and associated with the pivotal support (4) are disposed on either side of a line perpendicular to line connecting their centre points and which passes through pivot point (10) of the support and the primary shoe. A contour (15) on the support (4) falling away towards the pivot point (10) is in contact with the abutment (6) acts to provide compensation for lining wear - a more inclined orientation of support (4) arises and the distance between shoes (1, 2) becomes larger (see Figure 2). <IMAGE>

Title: Telephone interface unit
Inventor: WILLIAMS EMRYS
IPC: H04M11/06
Filed: 1982-03-30
Abstract: An interface unit for location between a data processor and telephone lines, operates to convert multifrequency tones signalled along the lines into digital form for computer input and to transmit synthesised speech derived from instructions from the processor. Supervisory tones used in the telephone system are recognised by counting means operating to count signal transitions and measure tone bursts. These are identified by means of a look-up table. Ringing current is received via a transformer which also receives speech signals. The line winding of the transformer is shunted enabling the ringing current to appear in the unit within the range of normally received speech currents.
