Abstract: 1,202,214. Reinforced concrete structures. G. OROSCHAKOFF. 18 Aug., 1967 [23 Aug., 1966; 6 April, 1967], No. 38105/67. Heading E1W. [Also in Division D1] Overlapping grid reinforcements 1, 2 spaning between supports for a concrete structure have the bars 3, 4 which extend longitudinally of the span sandwiched between layers defined by bars 15 of the respective grids which extend transversely of the span.

Title: Roll positioning mechanism
IPC: B29B7/68
Filed: 1968-08-09
Abstract: 1,212,729. Roll adjustment. FARREL CORP. 9 Aug., 1968 [28 Ang., 1967], No. 38230/68. Heading B5A. [Also in Division B3] A screwdown mechanism, for a rubber or plastics calender or a metal rolling mill, includes a piston which is coupled to one end of an adjustable roll, the piston being movable in a cylinder through which a continuous flow of hydraulic fluid passes. Conveniently, identical screwdown mechanisms are provided at each end of the upper and lower adjustable rolls in a 3-high calender or mill. The piston 23 of a mechanism 14 is coupled through a block 25 to the bearing 8 of a roll 6, the piston being movable within a fixed cylinder 18. Fluid introduced into the cylinder can escape through a gap 29, 30, 31 between the piston and a piston-rod 35. If the rolling pressure increases, for example, this gap is reduced by slight upward movement of the piston, and the resulting reduced escape of fluid causes an appropriate increase in the cylinder pressure. Thus a constant position of the roll is maintained, according to a preset position of the piston-rod 35. This position can be varied as desired by a motor driven screw mechanism 45 to vary the roll gap. Indeed the mechanism can be controlled, if desired, to maintain the pressure constant in the cylinder space, rather than keeping the piston at a preset position. For this purpose the pressure in the cylinder is sensed and the motor driving the screw mechanism is appropriately controlled. The pistonrod 35 is under tension during rolling or calendering, and the stretch of the rod can be selected to compensate for the normal extension suffered by the housings of the mill or calender. An overload valve can be used to prevent excess pressures from being generated in the cylinder. In an alternative form (Fig. 6, not shown), a piston-rod is normally held in compression, and a fluid gap is provided between the base of the rod and a co-operating roll support block.

Title: Fabric Flaw Detecting Apparatus
IPC: D04B35/20
Filed: 1967-08-29
Abstract: 1,185,722. Detecting fabric flaws photoelectrically. APPALACHIAN ELECTRONIC INSTRUMENTS Inc. Aug. 29, 1967 [Dec. 15, 1966], No. 39414/67. Heading G1A. In a knitted fabric flaw detecting apparatus for stopping the knitting machine when a flaw occurs, a movable sub-assembly is reciprocated by a motor driven cable or cord and magnet and reed limit switches along a path across the fabric as it emerges from the machine so that photo-electric means, which may be a photo-transistor, carried by the assembly produces a signal in response to a variation in the light from a source also on the sub-assembly reflected from the fabric or from beneath the fabric in the event of a flaw, and the circuitry is accommodated in two housings, one mounted on the movable sub-assembly and the other fixed, inter-connected by brushes engaging electrical contact strips extending along the path, a flaw signal varying the current drawn by the circuitry in the sub-assembly to cause the production of a stopping signal in the fixed housing. The motor stopping circuits includes relays and a silicon controlled switch. The trolley rail is an upwardly opening, channel-shaped formation carrying the contact bars on insulation panels at different vertical levels on opposite inside faces, and the trolley is supported by wheels operating respectively on downturned channel rims and obliquely in the lower corners of the channel, and separated by compression springs to prevent wobble. The current drawn by the sub-assembly circuitry is diminished by cutting off the current to the lamp and the machine is stopped. The operator then closes a start switch to operate a reversing motor and to introduce a time-delay into the detecting circuit to prevent a further shut down by the flaw. A switch is also provided to enable actuation of the detecting apparatus with the machine stopped so that the sensitivity may be adjusted and during this time, time-delay in the detecting circuit is reduced to permit more rapid adjustment. A suitable regulated D. C. power supply is described and a capacitor is provided across the shut down relay to prevent spurious actuation due to momentary loss of bus-bar contact. A single photo-transistor, or a pair of photo-transistors actuated by a flaw in one before the other, may be used, and light may be reflected by a strip beneath the fabric. The stopping apparatus may be rendered ineffective over desired areas. A Darlington amplifier including noise attenuating filters is described.

In an electron microscope where electrons passing through the object are directed on to a fluorescent screen the electron beam is deflected over an apertured diaphragm 5, Fig. 1, to interrupt the beam, the amplitude of beam deflection being varied to vary the time duration of beam interruption and hence to vary the image brightness. This enables focusing to equal image brightness despite variations in magnification. The deflection means may be electro-static as shown or magnetic and in the latter case is two coils with iron or air cores. The diaphragm 5 over which the beam is deflected determines the maximum illumination aperture. 6 is the object, 7 the objective lens, 8 a diaphragm, 9 the projection lens, 10 the fluorescent screen, 11 an inspection window.
