Title: Micropower zero crossing detector
IPC: H04L25/03
Filed: 1973-02-27
Abstract: 1365665 Zero crossing detector; frequency responsive switch MOTOROLA Inc 27 Feb 1973 [17 April 1972] 9348/73 Heading H3T A micropower complementing F.E.T. circuit provides pulses at zero crossings of an input signal but sets the output to a given state if the frequency of the input signal exceeds a given value. Complementary input signals A and B are received from a preceding bipolar transistor Schmitt trigger squaring circuit. The A signals are fed directly and via an inverter 12 to a NAND circuit 13 to provide short pulses at D at the positive going edges of the input signal, the pulse arising from the switching delay of the inverter. The B signals together with the A signals are fed to a frequency sensitive switch comprising two inverters 15 and 16 and an OR circuit formed from a NOR circuit 17 and an inverter 18. At normal frequencies the complementary input signals provide a continuous 1 signal at C and this is used to maintain a NAND gate 14 open allowing the zero crossing pulses at D to pass to output C. Inverters 15 and 16 are formed from F.E.T.s having longer channels so that they cease to follow at a lower frequency. The P channels of 15 and 16 fail first and accordingly the output for the higher frequencies goes to "0". Accordingly the NAND circuit produces a "1".

Title: Improved method of making ferrous metal articles from turnings or like scrap
IPC: C22B1/248
Filed: 1942-07-15
Abstract: 556,059. Making articles from chips, turnings &c. CONSTANTINE, W. W. (General Motors Corporation). July 15, 1942, No. 9813. [Classes 83 (ii) and 83 (iv)] Metal chips, turnings and like swarf including if desired small pieces or chunks of metal, particularly ferrous metal, are pressed in a mould to approximately the shape of the article required under a pressure of from 30 to 50 tons per square inch. The pressings are then passed through a sintering furnace to bring them to a temperature of from 1850‹ to 2050‹ F. the preferred range being from 1900‹ to 1950‹ F. The furnace has preferably a protecting atmosphere. The heated article is then pressed to final shape in dies giving a 24 per cent to 30 per cent reduction in volume. A boss 14, Fig. 9, may thus be attached to a sheet metal part 15. Turnings &c. from a hopper 21, Fig. 10, are transferred by a slide 22 of a die at 26 where they are consolidated on a closed die compressing the parts 25, 29 and 24, 28. After sintering the article 30 is placed on a die 31, Fig. 12, on descent of a top die head 41 with flanged ring 42 retaining die 43 the latter contacts an annulus 40 above the lower die and is arrested while the punch 47 enters the article and die 32 the upper die parts then all move together depressing the die 31 and causing toggles 35 to close the segmental dies 33 radially on the article which is thus compressed both axially and radially. Excess metal if any forms fins between the die sections. and in some articles may be utilized as part thereof. Levers, brake drums, containers, covers, sleeves, rings, cylinders &c. may be so made. In the case of brake drums certain chips or powders may be used to form the braking surface and the remainder of the die cavity may be filled with steel. Other metals may be combined with iron or steel and in some cases metals may be added which alloy during the final sintering and pressing. The alloying may be confined to particular surfaces or parts.

The driving-gear comprises two parallel shafts 28, 29 geared together by keyed spurwheels 30, 33, the sprocket 26 being fixed to the shaft 28. The rack 20 meshes with pinions 31, 34, which are slidably mounted on the shafts 28, 29 respectively and are connected by sliding one-way clutches 32, Fig. 5, to the spur-wheels 30, 33, the clutches being reversely arranged, so that both forward and backward oscillations of the rocker 19 effect forward driving of the sprocket 26. In order to enable the vehicle to be free-wheeled, the hubs of the pinions 31, 34 are channelled to receive a. lever 36, Figs. 5 and 6, pinned to a horizontal arm 37, which slides in a guide 38 and has its inner end bevelled at 39 to engage the bevelled end of a spring-pressed pin 40, the upper end of which engages a cam boss 42 on the rocker 19, whereby on further downward pressure of the foot at the end of a stroke, the pinions 31, 34 are declutched. On downward pressure of the other foot, the cam face is moved off the pin 40, the pin is raised by its spring, and the clutches are returned to normal position by their springs 50. In a modification, the rocker 19 has two racks, the gearing on the shafts 28, 29 being suitably modified.

[Class 97 (i)] [Also in Group XXIII] In order to reduce the proportions of incident light reflected by glass, the surfaces are repeatedly wetted, as by dipping, with a solution of silicon tetrachloride, silicon tetrachloride or silicachloroform in a volatile non-aqueous solvent such as carbon tetrachloride. Each coating is dried and rubbed until it is bright and the process repeated until a purple line in the case of a glass containing about 72 per cent of the silica (refr. index about 1.52), or a deep bronze purple in the case of a glass containing about 30 per cent of silica (refr. index about 1.7) is observed when the.glass is viewed at an obtuse angle. The formation of the coating is accelerated by adding a ketone, particularly acetone, to the solution.
