Title: A hide stretching and pressing machine
IPC: C14B1/12
Filed: 1928-07-12
Abstract: 319,435. Marks, E. C. R., (Machinery Development Co.). July 12, 1928. Reciprocating and rotating tool machines.-In a machine for stretching and pressing hides, a rotatable table carrying a setting-out board is provided, the table being adapted to be moved into successive engagement with an eccentrically-mounted clamping device and with a hide stretching and pressing device reciprocable from a position between the clamp and the axis of rotation of the table to the farther edge of the table. The setting-out board 22 is supported on a table 14, Figs. 1 and 2, journaled in a frame 13 supported by a pedestal 12 in a standard 11. The table is provided with rollers 16 by which it is movable on the frame 13, and with stops 17 engageable by a spring- pressed detent 20 for holding it in one of two positions. The frame 13 is connected by links 33 and pairs of pivoted levers 29 to links 35 adapted to be actuated by a treadle 38, the frame and associated parts being counterbalanced by a weight 39. Depression of the treadle results in the raising of the table 14 so that a hide supported on the board 22 is engaged by a spring- pressed clamp 24 extending transversely across the machine. The clamp serves to hold the hide in position while it is pressed and stretched by a rotating roller 44 provided with helical and straight blades 45, 46 respectively. The roller is rotated by gearing from an electric motor mounted on a carriage supporting the roller and consisting of side members 47, 48 and cross-bars 49. The shaft of the roller is provided with rollers running in a track formed by members 53, 56 of the machine frame, and the roller carriage is also provided with rollers 51 running on top of the members 53. The carriage is provided with lugs 75 attached by links 73 to crank-pins 72 on flywheels 71 driven from a shaft 66 so that the roller is reciprocated. The speed of rotation of the roller is greater than the speed of reciprocation. In use, the table is raised to cause the hide to be clamped by the clamp 24 along one edge, the lifting of the table being timed so that the roller 44, during its outward travel, engages the hide at about the middle so as to stretch it and press it on to the setting-out board, adhesive being previously applied to the hide so that it is secured to the board. The movement of the roller causes the hide to be progressively secured to the board and stretched from the part pasted down instead of from the clamp 24. The table is then rotated 180‹ and the operation is repeated; the position of the hide is then changed to enable it to be similarly treated in directions at 90‹ to the previous operations. The board 22 is preferably resilient to allow for irregularities in the hide surface. In a modification, the levers 29 are provided with toothed quadrants at their outer ends and engage gears 41, Fig. 4, running 'on fixed racks 42 and provided with crank arms 43 connected to the links 33.

Abstract: 1511016 Selector system for TV channel selector TEXAS INSTRUMENTS Inc 14 May 1975 [22 May 1974 (3)] 20427/75 Heading H3Q [Also in Division G41 A system for selectively energizing one of 2<SP>n</SP> devices 92a-92p or 93a-93p comprises (a) input terminals A, B, (b) output terminals O, P, (c) 2<SP>n-</SP><SP>1</SP> additional output terminals D-K, and (d) an nstage binary counter 21 operative in response to and during the application of an input signal (e.g. 0) to A or B to produce a signal (e.g. 1) alternately at O, P and to produce through a decoder 22 a signal (e.g. 1) at terminals D-K one at a time in a first sequence when said input signal is applied to A and in the reverse sequence when it is applied to B; each terminal D-K being connected to a unique pair of said devices 92, 93 and each terminal O, P being connected to a respective one of said pair. As described, the system is part of a TV channel selector operable directly through switches 81a-81p or by remote control to connect a potentiometer 92 to a voltage controlled tuner, and to actuate a channel indicator (e.g. neon bulbs) 93. In the remote control mode, input A or B is grounded (switch 62), causing counter 21 (flip-flops I-IV) to count clock pulses 23 up or down respectively. The outputs of the least significant bit flip flop I form "odd" and "even" outputs O, P while the higher order outputs from flip flops II-IV are decoded at 22 to give a 1-out-of-eight signal D-K; O, P and D-K define the selected channel uniquely. Remote control is stopped when the desired channel is reached. In the direct control mode a switch 81a-81h or a switch 81i-81p is pressed so as to ground input A or B according as an even or an odd channel is required (e.g. 81f or 8 In for channels 10 or 11). The counter counts up or down as before until that output line (e.g. 65 for I) is reached which corresponds to the pair of channels (e.g. 10/11) containing the one selected, at which point a '1' level is fed back to the counter via A or B to stop it; Counting up or down ensures that the correct output O or P is selected as well as (e.g.) output I. The outputs D-K and O-P are fed to analog switches IC 902 A-D, Fig. 5 (not shown); each output O, P selects a pair of switches, while each output D-K selects an input within that pair. This results in the selection of a unique one of 16 outputs of the switches for a potentiometer 92 and an indicator 93 corresponding to the desired channel. The counter may be operated at two different clock rates according as the command is a remote or direct one; the former mode requires a slower speed to provide reaction time for the operator to discontinue the command signal, while the latter mode is effectively instantaneous. A detailed circuit diagram is also provided (Fig. 4, not shown).

Title: Improvements in or relating to purification of semi-conductor material by zone drawing
IPC: C30B13/32
Filed: 1960-06-10
Abstract: A rod of semi-conductor material is subjected <PICT:0922286/III/1> to zone-melting by vertical passage through a stationary induction heating coil, incipient change in the electrical conditions in the induction coil circuit produced by change in the diameter of the molten zone being utilized to effect relative movement of the ends of the rod to maintain the diameter of the molten zone substantially constant.  The zone-melting may be effected in a quartz vessel in a vacuum or protective gas atmosphere.  The rod may be preheated by the passage of an electric current longitudinally therethrough.  As shown in Fig. 1, a motor-actuated rotating lead screw 8 effects simultaneous movement of both ends of a semi-conductor rod 1 relative to a stand 11 and an induction heating coil 14 by means of a nut 9, while a motor-actuated rotatable lead screw 7 effects relative movement between the ends of the rod by means of nut 5 when necessary.  Fig. 2 (not shown) illustrates a similar apparatus. According to Fig. 3 (not shown), a motor-actuated rotatable nut engaging the motor-actuated rotating lead screw effects the relative movement between the two ends of the rod.
