Title: Improvements relating to the erection and construction of buildings and to apparatusfor use therein
IPC: E04G21/18
Filed: 1945-05-18
Abstract: 596,334. Bricklayers' lines etc.; casting mortar &c. in situ. ELLIOTT, S. V. May 18, 1945, No. 12617. [Class 20(ii)] [Also in Group XXX] A brick or like solid or cavity wall is erected and rendered on at least one face, by erecting uprights outside the corner sites of the proposed wall with means for fixing a vertically movable jig or template to the uprights at progressively increasing heights as wall construction proceeds, the jig serving as a guide for laying bricks which are spaced the thickness of the rendering from the jig, and serving also to confine mortar or other rendering between the facing member and the bricks. The rendering can be achieved in stages as individual bricks are mortared in, or the rendering can be filled in subsequently between the jig and the laid bricks. The uprights at a face of the wall which is not to be rendered may support a line. When applied to the construction of houses or other multiwalled buildings, all major walls are erected together in stages. Each upright at an internal corner may consist of an angle member 16, Fig. 1, having a footplate to receive a securing screw 18, and also a lug 19 carrying the upper ends of adjustable struts 21 secured at their feet by screws 23. The jigs 26 are of channel section, part of the flanges being removed to enable U- shaped plates 27 having clamping screws 29, to be welded to the webs, the jigs thereby engaging and being adjustably secured to the uprights. The uprights 17 at external corners are of Y-section, and are clamped in brackets 24, Fig. 3, which are held in place in the partially built wall by a removable brick. The member 17 is adjusted to the vertical by a set screw 25<1> and is clamped by screws 25. Lines 32, Fig. 4, for horizontals may be carried by brackets 34 having U - pieces engaging fianges on box section uprights 31. The lines are tensioned by springs at their anchorage points. The jigs 26 are supported at intermediate points along the length of the wall by uprights of T-section. The uprights 16, 17 are connected at their upper ends by a plate. Winches 40, Fig. 7, may be clamped at the upper ends of the uprights to facilitate the lifting of the jigs. Specification 236,956, [Class 20(ii)], is referred to.

Title: Improvements in or relating to the triggering of a triggerable device
IPC: G01R13/32
Filed: 1969-03-12
Abstract: 1,241,732. Semi-conductor trigger circuits. TEKTRONIX Inc. 12 March, 1969 [15 March, 1968], No. 12926/69. Heading H3T. A triggerable device such as a tunnel diode 20<SP>1</SP> to be triggered by a pulse from an input 34 when a hold-off signal F at a second input ceases, is first primed by the triggering of a second device such as a tunnel diode 14<SP>1</SP> in response to the first input pulse at 34 after cessation of the (negative) hold-off signal F, and is then triggered into its second state by the same input pulse delayed by, for example, a delay line 22<SP>1</SP>. This avoids jitter (inaccurate triggering) of tunnel diode 20<SP>1</SP> which could arise if the input pulse at 34 and the hold off signal F were applied directly to diode 20<SP>1</SP> and if the input pulse coincided with the changeover of the hold off signal between its two levels. The tunnel diode 20<SP>1</SP> may trigger a time base for an oscilloscope. The hold-off signal F, existing for example during the time taken for a time base sweep to recover, holds the base of T74 negative to cut it off. The potential of diode 68 cathode is then maintained by the chain 70, 72, 76 sufficiently positive to prevent switching of tunnel diode 14<SP>1</SP> to its high voltage state by any input pulses at 34; and also T80 is held off by diode 68, so that T88 emitter is somewhat negative to stop tunnel diode 20<SP>1</SP> from switching. When the hold-off signal ceases, T74 conducts, and diode 68 is reverse biased. Resistors 62, 64, 66 hold tunnel diode 14<SP>1</SP> in a primed state so that it is switched to its high voltage condition by the next input pulse at 34; thereupon T80 conducts, T88 emitter goes above earth potential due to current through 102, 100, 98, 96, 94, and tunnel diode 20<SP>1</SP> is primed. When the delayed input pulse which triggered 14<SP>1</SP> reaches 20<SP>1</SP> the latter is also triggered. (For Figure see next page.)

Abstract: 566,104. Turning. MOORE, C., and WESTBURY, E. T. Aug. 18, 1943, No. 13412. [Class 83 (iii)] In a turret attachment for a small lathe, a selector stop bar is secured to a shaft which is rotated intermittently by the turret through pins on the lower face of the latter engaging recesses in a polygonal prism attached to the shaft. The turret A is rotatable on a stud B attached to the slide C which is traversed along the lathe bed D by a hand lever N pivoted at N<1> on the bed and engaging a pin N<2> on the slide through a tumbler N3. The selector stops H are carried by a disc H<1> mounted on a shaft G rotatable in the slide C and carrying a prism J having as many sides as there are tool stations in the turret. Normally, one of the flat sides of the prism lies against the base of the turret to lock the stop disc against rotation, but when the turret is rotated for indexing, one of the pins E arranged in a circle on the turret base engages a recess J<2> in the prism to rotate it and index the stop disc, cavities A<1> being provided on the turret base in line with the pins E to clear the corners of the prism. The turret is indexed by a pawl L engaging a ratchet M on the base of the turret, the motion of the pawl with the slide C during its rearward traverse being prevented by a rod K engaging a fixed stop. The rod K may be returned on the forward traverse by a spring K<1> or may be attached to the stop for positive action in both directions. An index bolt O in the slide C is withdrawn from a recess O<1> in the turret against spring pressure, prior to indexing, by a bell-crank lever P pivoted on the slide engaging a fixed cam R during the rearward traverse. Lost motion is provided between the bolt O and lever P so that the latter may ride over the reverse side of the cam R during forward traverse of the slide.
