Title: Improvements in or relating to freezer tray assemblies
IPC: F25C1/24
Filed: 1956-06-12
Abstract: The water-repellent coating of a domestic ice-tray consists of polytetrafluoroethylene.  The tray surface is first finely roughened, e.g. by anodizing if made of preferably sintered aluminium, and then coated with an aqueous dispersion of the repellant, the dispersion including a surface-active agent obtained by condensing ethylene oxide or propylene oxide with a longchain alkyl phenol.  The dispersion may include an oxidizing acid such as chromic acid to improve the bond.  The coated tray is then heated gradually to remove the water without blistering and then is heated at a temperature above the melting-point of the repellant, i.e. above 700 DEG  F.  The coating is then toughened and improved as to transparency by quenching in water.  Two coats may be applied.  Specification 796,587, [Group XIII], is referred to.

Title: Circuit arrangement for maintaining the length of d.c. pulses constant
IPC: H04L25/03
Filed: 1958-06-06
Abstract: 886,252. Pulse shaping circuits. STANDARD TELEPHONES & CABLES Ltd. June 6, 1958 [June 11, 1957], No. 18151/58. Class 40(6). [Also in Group XL(b)] The Figure shows a circuit for re-shaping pulses such as telegraphic pulses which have been distorted by passage over a transmission path. The negative going distorted input pulse U1 is applied across a resistor W to the two wires of a transmission line. At first the resistance of rectifier Grl is very small so that the potential at point D is approximately equal to that at point C. As the input voltage rises negatively U2 rises as long as Ul is smaller than the bias voltage UV. If U1 exceeds UV rectifier Gr3 conducts thus acting as a limiter. As voltage Ul continues to increase negatively capacitor Cl charges to the peak amplitude of Ul less the biased voltage UV. The charge on capacitor C1 at first remains constant until it discharges over rectifier Gr2 so that an output wave form U2 is produced. The re-shaped output signal is phase shifted with respect to the input signal and may be further squared by applying it to trigger a relaxation stage the final output signal being a square pulse having the same duration as the original undistorted input pulse but phase shifted with respect to it.

Abstract: 477,950. Locking valves. MOORWOODS, Ltd., and PENNINGTON, A. H. July 1, 1936, No. 18280. [Class 135] [Also in Group XVIII] Steam is supplied to the interior of an oven 2 through pipe 5 and 3-way valve 4 having an actuating spindle 6 with hand lever 6b. The door 7 is fitted with diagonal bolts 8 and vertical bolts 9 operable simultaneously in known manner by a central member 10. The upper end of the bolt 9 is provided with a slotted bracket 13 which is engaged by a curved arm 14 on the hand lever 6b when lowered.

[Also in Groups XII and XXVIII] A gas turbine engine comprises a piston reciprocable in a cylinder to compress air into a combustion chamber and a gas turbine driven by gases from the combustion chamber, the turbine shaft extending axially within the cylinder, and the piston being rotatable with the shaft and being arranged to reciprocate by means of a screw mechanism. The engine shown comprises two turbine rotors mounted at either end of a shaft 6, only one rotor 4 being shown. A piston 2 is mounted on the shaft 6 and is given a helicoidal motion within the cylinder 1 by means of studs 8 in the wall of the cylinder which engage helicoidal grooves 9 formed in the cylindrical sleeve 10 constituting part of the piston wall. The cylinder is connected by inlets 13 to an annular combustion chamber 12 to which fuel is supplied by an injector 21. The gases pass through the outlet 15 to the turbine rotor and then escape through the exhaust duct 44. The inlet and outlet ports of the combustion chamber are controlled by valves 14, 16 mounted on common stems 17, the valve stems being operated by means of a ring 29 formed with a cam groove 28 which causes reciprocation of rollers 27 which in turn reciprocate the plate 22, the plate being constrained against rotation by means of guidepins 23. The plate is held against the cam followers by means of a spring 26. The plate 22 carries adjustable studs 24 which engage studs 25 screwed into the valve stems 17 on each of which the valves 14, 16 are mounted. Air is supplied to the compressor cylinder by means of a rotary blower 35 which is either driven by the engine or by a waste gas turbine. The blower rotor and shaft are arranged to slide axially so that the portion 38 may engage the seating 37 on the blower casing so as to regulate the pressure of the air delivery. The air is delivered to the cylinder 1 through the annular air duct 31 and ports 32.

Abstract: 241,318. Stibbe, G. Aug. 1, 1924. Circular machines.-One or more needle-beds are provided in each of which there is a single 'set of needles actuated for loopforming purposes by a single cam system so that the needles are divided at the feeders, some being caused to knit while others do not knit. Fig. 1 shows portions 1, 2 of the cylinder and dial cam boxes corresponding to two adjacent feeders. The needle cylinder carries two kinds of needles 3, 4 arranged in alternation or otherwise, the needles 3 having long butts 3a and short tails 3b while the needles 4 have short butts 4a and long tails 4b. The dial needles 5, 6 are arranged similarly to the cylinder needles, the needles 5 having long butts 5a and short tails 5b. while the needles 6 have short butts 6a and long tails 6b notched at 6c. The cylinder cams are so arranged that at one feed the butts 3a pass along an idle track 9 while the needles 4 are lifted by a cam 8 acting on their tails 4b so that their butts 4a pass above the point of a cam 11; these needles clear their loops and knit. At the next feed the short butts 4a pass along an idle track while the long butts 3a are taken up by the. extension 14 of a clearing cam 13. If a dial is used, the long butt needles 5 may co-operate with the short butt cylinder needles 4, while the short butt needles 6 co-operate at the next feeder, with the long butt needles 3. For this purpose there may be provided, at one feed, an idle track 18 for the butts 6a and a track 19, leading to a clearing cam 20, for the butts 5a. A guard cam 22 engages the notches 6c. At the next feed a cam 23 pushes the butts 6a past the point of a cam 24a leading to a clearing cam 26 while the butts 5a pass along an idle truck 24. In a modification, the butts approach the clearing 'cam 11, Fig. 8, at one feeder, at a common level 39 above the point 40 of the clearing cam 11. The long butts 3a are engaged by a cam 41 which passes them into an idle track, while the short butts 4a pass over the cam 11 and knit. A guard cam 43 prevents the short butt needles from dropping. At the next feed the short butts remain down and the long butts are raised on a cam 44 so as to pass over a clearing cam 13. When the. arrangements described above are employed in cylinder or dial only. the dial or cylinder may carry two sets of needles, operated as described in Specification 20409/08. Specifications 4339/96, 18140/96, and 8993/98 also are referred to.
