Abstract: 1,136,449. Razors. GILLETTE INDUSTRIES Ltd. 21 Nov., 1967 [8 Dec., 1966], No. 54934/66. Heading B4B. A safety razor head comprises two spaced skin-engaging shoulders in the gap between which is the cutting edge of at least one razor blade, the effective width of each shoulder being at least 1/ 16  inch and the aggregate of the effective width of the two shoulders and of the width of the gap between them being at most ¢ inch, the blade being disposed at an angle to the plane of the shoulders of from 22 to 32 degrees, the head providing a guard support for the skin which extends parallel to the cutting edge and is spaced from it by a distance of from 0.015 to 0.045 inch, and the cutting edge of the blade having an exposure relative to the plane of the shoulders of from +0.004 to - 0.004 inch depending upon the width of the gap between the cutting edge and the guard support. In the form shown in Fig. 2, two blades 1 are provided in the gap between the shoulders 4, the cutting edge of each blade constituting the guard support for the other blade, the exposures of parts of the two cutting edges lying directly opposite one another not differing by more than 0.003 inch. The channel 5 behind the cutting edges serves to receive shaving waste and to allow easy rinsing of the blades. In the form shown in Fig. 4, only one blade 11 is provided in the gap between the shoulders 14, the guard support being constituted by the edge of the shoulder in front of the cutting edge 12 of the blade. The blade or blades may be permanently secured e.g. by moulding, in a unit which provides the shoulders and constitutes a complete razor head. The unit may include a handle so as to constitute a complete razor, which may be disposable, or may be removably secured to a handle which may comprise a pair of jaws.

Abstract: 1,153,238. Acoustic inspection devices. HEATH Inc. 12 Dec., 1967 [6 Oct., 1967], No. 56396/67. Heading H4D. A wooden pole is tested for internal decay by generating an impulse on one side of the pole, detecting acoustic energy with a transducer positioned on the opposite side of the pole, filtering the transducer output into two different frequency bands, and providing a meter indication of the relative energies in the two bands. As shown, the pole 10 is struck by hammer 12 at ground level and transducer 13 output is filtered into a high frequency band (1 kHz to 5À2 kHz) and a low frequency band (160 Hz to 600 Hz) for separate amplification in amplifiers 30, 30a. The amplifier outputs are applied via respective diode/capacitor smoothing circuits (in output circuit 37) to the two terminals of a difference meter. It is stated that a sound pole gives predominantly high frequencies, and the apparatus is calibrated such that a meter deflection one side of centre indicates a sound pole and a deflection the other side indicates a decayed pole. Circuit details are given.

Abstract: 1392780 Knitting machines C MARTINELLI 10 Dec 1973 [11 Dec 1972] 57174/73 Heading D1C A device for tensioning the side edges of knitted fabric 2 in a flat knitting machine comprises a pair of tensioning weights 4 provided with suspension hooks 8 for engaging the respective edges of the fabric and formed with vertically extending spaces 12 through which passes a repositioning rod 13, the rod 13 being periodically raised to engage carriages 10 attached to the weights 4 and thereby detach the weights from the descending fabric and lift them to a new position of suspension nearer the needle beds, the rod being subsequently lowered to a rest position spaced below the carriages so as to allow the tensioning weights to descend once more with the fabric. The rod 13 is raised and lowered by means of an electric motor 15 and crank drive 17, 18 through a rocking lever 20 and supporting arms 14. A guide bar 23 engaged by rollers 22 on arms 14 causes the rod 13 when raised and lowered to move towards and away from the fabric 2, a run-up surface 30 on one of the needle beds 1 serving to pivot the hooks 8 about the rod 13 towards the fabric. When the knitting machine incorporates a narrowing/widening device employing at each side edge of the needle beds a carriage which is displaceable longitudinally of the beds, the carriages. The carriages 10 are biassed outwardly of the rod 13 by ropes 24, springs or counterweights into engagement with guide stops 27 slidably mounted on a guide rod 25, and connected by ropes 28 to the corresponding carriages of the narrowing/widening device. The electric motor 15 may be switched on automatically after a predetermined number of strokes of the knitting carriage and switched off, after a single rotation, by a switch 29.

Relative movement of the earth strata distorts the rod 1 and the extent of the movement is determined by measuring the changes in resistance of the strain gauges 7, 8 in bridge circuits. Gauges 7, 8 are mounted at right angles to each other to determine movement in two perpendicular directions. The tie rod has a non-smooth exterior surface to facilitate adhesion, and in one embodiment has a series of spaced circumferential ribs. Several tubular tie rods may be coupled together by sleeves which incorporate plugs and sockets for the leads from the strain gauges. An assembly of four tie rods 41-44 Fig. 2 may be inserted symmetrically as shown through the wall of a cavity 40 in a mountain, the holes for the tie rods being made with a core drill which enables the different layers L-O to be examined, whereby the position and number of strain gauges is predetermined. In an alternative form Fig. 4 the tie rod 69 has strain gauges 63 mounted along its longitudinal axis.

Filed: 1973-12-11
Abstract: 1443766 Selective signalling ROBERTSHAW CONTROLS CO 11 Dec 1973 [12 Dec 1972] 57395/73 Heading G4H In a supervisory control system, a central station can address a plurality of field points at each of a plurality of remote stations using messages in bi-phase code, each remote station passing the message bits to a decoder via gating means enabled by bit window pulses generated with a delay of substantially one bit time from each bit signal. As disclosed, messages sent in each direction between the central station and remote stations are in biphase code using positive-going and negative-going transitions for the two bit valves respectively. Each message consists of a sync. portion followed by two identical words, each word having address and function portions. The receiving station recognizes the sync. code and causes each bit to produce a window pulse to gate the next bit, failure to find this next bit causing reset. The two words are compared, with resetting if unequal. Assuming no such resetting, the central station thus selects remote stations in turn and selects inputs/outputs and monitors/ controls them. Monitored states/values are sent to the central station as above. The central station address starts with a 1, whereas each remote station address starts with a 0.

[Also in Division F2] In a press of the type in which a body of, e.g. powdered material, is subjected to high hydraulic pressure in a cylinder closed at each end by slidable closures and located during the pressure applying operation between a pair of fixed yokes, a piston and cylinder device is located adjacent one of the closures and is operable to force the closures into their fully inserted positions in the cylinder after the pressure applying operation to ensure a clearance between the closures and the yokes thus facilitating easy removal of the cylinder and closures from between the yokes. In the described embodiment, the cylinder 2, containing the body to be pressed, and closures 7 and 8 are located during the pressure applying operation between the yokes 26, 27 of a stand 22 reciprocable into and out of position by a cylinder 30 mounted upon a stand 1 which slidably supports the cylinder. The lower closure 8 is resiliently suspended by means of a spring biased ring 13 and is provided with a cylinder 17 having a piston 18 supported from the closure by a return spring 19. In operation, -fluid under pressure is introduced into the cylinder through channel 16 in the closure to effect the pressing, the closures being forced outwardly under the pressure into tight contact with the yokes. After the release of the pressure and after the previously stressed stand has returned to its former dimensions, pressure medium is supplied through channel 31 to the cylinder 17 thus causing the closure 8 to be forced upwardly to its innermost position. The continued application of pressure to the cylinder causes the closure 8 and the cylinder to rise relative to the upper closure 7 until that closure has reached its innermost position. The pressure is then released and the stand is easily removed by cylinder 30.
