Abstract: 1315222 Photographic processing apparatus INTERNATIONAL BUSINESS MACHINES CORP 7 Jan 1971 [15 Jan 1970] 757/71 Heading G2A Semi-conductor wafers 11 are processed in a turret machine 10 having a plurality of extensible wafer pick-up heads 25A, 25B, Fig. 1, arranged in sets 25, a plurality of sets of wafer process stations 50 being spaced from a turntable 13 which support the pickup heads and from each other. Intermittent relative motion between the pick-up heads and the process stations is effected so as to align the process stations and the pick-up heads successively from station to station whereby wafers held by one of the pick-up heads of a set enter alternate ones of the process stations of the sets of process stations. Wafers are loaded at a station 14 on air slide conveyors 75 and are held on the pick-up heads with their exposed sensitised surface facing downwardly by a vacuum coupling. Each process station 50, Fig. 10, comprises a chamber 175 having an entrance 177 dimensioned to receive one pick-up head, a sealing member 170 sealing the chamber when a pick-up head is inserted. An upwardly directed atomising spray nozzle 179 is connected to a liquid supply reservoir 184 and an air pressure line 185 so as to direct a liquid spray to the face of the wafer 11. After processing, a wafer may be dried by removing the spray nozzle and replacing it with a heated air supply. The apparatus is preferably arranged so that each wafer enters alternate ones of each set of stations to give a series of six separate processes. Alternatively, the wafers may be conveyed first through stations 50A and then through 50B to give a series of twelve separate processes. The machine is automatically controlled to load and unload wafers, sensing and recording the presence and location of wafers at the several process stations, activating the spray processing, and starting and stopping the indexing cycle of the machine.

Title: Commutatorless converter fed motor
IPC: H02P6/14
Filed: 1953-01-12
Abstract: 725,802. Converting. BROWN, BOVERI, & CIE AKT.-GES. Jan. 12, 1953 [Jan. 19, 1952], No. 904/53. Class 38 (2). Windings of a motor are fed through valves with grid-controlled anodes arranged in groups of four, each group comprising two pairs such as b, c; d, e; f, g ; h, i, the members of each pair being connected respectively to the ends of the secondary winding of a transformer, centre tapped at a, while the two cathodes associated with the anodes of each pair are connected together, the two joined cathode pairs of each group of four being connected to opposite ends of a reactor centre tapped at k. The tappings a and k are connected to fixed points I, II, III, IV symmetrically disposed around the motor winding. The grids of the valves are impulsed simultaneously at the supply frequency for speed control and at a frequency proportional to the motor speed, and the pairs of valves fire in succession, each for a quarter of a revolution where, as in Fig. 1, there are four pairs of valves. The whole of the motor winding carries current substantially continuously. Commutating voltage may be provided from commutating poles which are continuously excited by parallel windings connected in the leads to the ends of the reactors. Compounding may be effected by similarly connected parallel windings on the main poles. The commutating poles may have damping coils or cages. When the poles rotate to avoid too many slip rings the parallel windings may be the field windings of a separate exciter which supplies the poles of the main motor with proportional D.C. In modifications there may be three or more groups of four valves, Fig. 2 (not shown), the supply may be polyphase, Fig. 3 (not shown), and the motor windings may be connected in star, Fig. 3 (not shown).

Title: Improvements in or relating to systems for recording, reproducing or transmitting signals by means of electric currents
IPC: H03G3/20
Filed: 1936-01-10
Abstract: 452,084. Automatic volume control. ELECTRICAL RESEARCH PRODUCTS, Inc., 195, Broadway, New York, U.S.A. Jan. 10, 1936, No. 948. Convention date, Jan. 15, 1935. [Class 40 (iv)] [See also Group XL] In signal transmission, recording or reproduction using compression and/or expansion of the range of volume variations, the compressor (and/or expander) is designed to be ineffective at input volumes above and/or below a definite level or levels. As shown in Figs. 4 and 5 for example, below and above given limits, variations in input volume produce equal variations in output volume. Between these limits however the range of variations is compressed or expanded. Different limits, indicated by the numerals 1 ... 5, are given by a preliminary adjustment of the apparatus. An application of the invention for improving the signal/noise ratio, Fig. 3 (not shown), consists in arranging for expansion only when the received level is below the lowest necessary signal level. Figs. 6 and 7 show circuit arrangements of a compressor and expander respectively. Signals received at 18, 19 if of sufficiently low level suffer a fixed amount of attenuation in the apparatus 23 ... 28. At a given level, determined by the setting of loss networks 32 .. 36 and 42 .. 46, the voltage drop produced in resistance 49 by rectifying signals tapped from the transmission path overcomes the battery 51 and the valves 27, 28 begin to cause the attenuation of the network 23 ... 28 to vary with the signal level. A condenser 50, connected to resistance 49 by a variable tapping, controls the time taken for a given variation to take effect. At a second (higher) volume level, the peak voltages from the transformer 37 overcome the paralyzing effect of batteries 54, 55 on valves 52, 53 which hitherto have been without effect, signals in the control path having been simply amplified by the pair 38, 39. The pair 52, 53 opposes the pair 38, 39, and consequently, variations in input level when a definite level has been passed do not alter the attenuation of the network of 23 ... 28 and are reproduced in the output circuit by variations of the same extent. The expander shown in Fig. 7 operates in a similar way except that the transmission equivalent of the signal path is adjusted by varying the gain of a repeater instead of the loss of an attenuator and that amplifiers 57, 58 are added to the control path. Distortion due to the fact that the impedance of the variable-gain repeater varies whereas that of the output transformer does not, is minimized by the resistances 70 ... 73 and condenser 74.
