Filed: 1966-11-29
Abstract: 1,151,520. Development apparatus. INTERNATIONAL BUSINESS MACHINES CORP. Nov. 29, 1966 [Dec. 3, 1965], No.53270/66. Heading G2A. Sensitive material is developed by contacting with a developing fluid in a fluid tight chamber having a developing fluid inlet and two opposite walls, one of which is formed by the sensitive material or the material and a support therefore, wherein on admitting the developing fluid to the chamber, relative movement, in an outward direction, transverse to the planes of the walls, occurs between the said walls. The described embodiments relate to the use of ammonia under pressure as the fluid, wherein one of the walls is fixed and the other is moved by the pressure of the ammonia. When the sensitive material is carried on a rigid support brought up to sealing edges of the chamber, the opposite side may be flexible or rigid and resiliently biased, e.g. by a resilient pad or compressed gas, towards the material, the bias being overcome by the ammonia pressure. When the opposite side is fixed, the sensitive material may be carried on a support having a central depression, which may be covered by a flexible sheet, or the support may have a movable central section biased against depression, such that admittance of the gas causes the sensitive material to flex into a depression. The inlet port may be towards one edge of the material, and an exit port may be included at the opposite edge, so that the ammonia passes across the sensitive material to displace air and effect a "wash" development.

IPC: C08G77/12
Filed: 1966-12-07
Abstract: A linear organopolysiloxane having a viscosity less than 100 csts. at 25 DEG  C. is made by contacting a cyclic organopolysiloxane, alone or in admixture with an a , o -dihydroxyorganopolysiloxane, with a monohalogeno-organosilane in the presence of FeCl3, and hydrolysing the product obtained.  The starting siloxanes and end products contain Si-bonded H atoms or alkyl, alkenyl or aryl radicals with or without halogen or cyano-substituents, but the end products do not contain more than 2 H atoms on each terminal Si atom.  Where the reaction is effected at low temperatures, an organodihalosilane is added to the initial siloxane (to lower the freezing point of the mixture and to eliminate water) prior to addition of the silane reactant.  In a typical Example (1) a mixture of oil 5 (which is a mixture of cyclic and OH-terminated dimethylpolysiloxanes obtained by hydrolysis of (CH3)2SiCl2), (CH3)2SiCl2 and FeCl3.6H2O was coole to - 3 DEG  C., and cooled further to - 10 DEG  C. as CH3H2SiCl was added thereto; the mixture was allowed to heat up to - 2 DEG  C. and then gradually hydrolysed with water at 4 DEG  C. to yield an oily layer which was separated and purified.

A machine for closing and tying the necks of bags comprises a pair of guides 146, 148 and continuously inwardly moving belts 60 which grip the bag and draw it into a tying location 22, means controlled by a cam 82 to gather the neck and place a bight of tying material round it when its presence is detected by finger 194, and a cutter 114 which simultaneously severs a length of the tying material and twists it, and forks 166, 168 which grip the bag and eject it in a transverse direction. Movement of finger 194 energizes the solenoid which controls the rotation of control cam 82, and the neck of the bag is gathered together and positioned by arms 174, 176 of the ejecting forks. Tying material is fed through a die plate 112 and through an eye 142 in a needle 144. This needle is rotated, through linkwork, by cam 82 to bring it into contact with the bag-neck and so wrap the tying material 180 degrees round the neck. The slot 154 of the needle compresses the neck of the bag against arms 174, 176. Further rotation of the cam 82, then rotates the tying head 106 through gearing (94, 98), to twist the ends of the tying material. Simultaneously with this, the cutter 114 severs the tying material at die plate 112. This action clears the tying material from the needle, which is then returned to the position shown by the cam 82. This cam also operates the ejector 26 which comprises the pair of forks 166 and 168 on either side of the tie and secured to a shaft 170. Each of these forks has gripping arms 172, 176 so that when they are rotated clockwise, Fig. 3, on shaft 170, the long arms 172 grip the bags 18 against anti-friction plate 192 to eject them in a lateral direction to position 120, Fig. 3. After ejection of the bag, a drive wheel 128 rotates to advance a predetermined length of the tying material 120 towards the needle. A sensor 240 cuts the machine off when the spool 122 is empty, Fig. 2.

Abstract: 1381260 Converting F L F STEGHART 24 Nov 1971 [24 Nov 1970] 55785/70 Heading H2F In a frequency changer of the A.C.-D.C.-A.C. type, a starting circuit is arranged to initiate operation of the driver for the D.C.-A.C. section after a predetermined number of trigger pulses for said D.C.-A.C. section have been generated. General.-Fig. 2 shows a single-phase converter or one phase of a three-phase converter. A.C. at terminals A, N is converted to D.C. by means of a bridge (Fig. 3, not shown) of two thyristors and two diodes, the output being filtered (Fig. 4, not shown) and fed to an inverter (Fig. 5) comprising a bridge of thyristors CSR1 ... CSR4 triggered by a driver (Fig. 8, not shown). The pulsed output of the inverter is converted to sine by means of a filter (Fig. 7) having current limiting facilities, giving an output from a transformer to terminals A, N of the required frequency. The output is monitored and regulated by controlling the conduction angle of the thyristors in the A.C.-D.C. section. The frequency of the inverter is determined by means of a unijunction transistor oscillator feeding a ring counter comprising three bi-stable circuits (Fig. 9, not shown), power supply for the inverter driver being turned on by a start circuit (Fig. 11) after counting a predetermined number of clock pulses.  Inverter.-Fig. 5 shows the inverter comprising a bridge of four thyristors CSR1 ... CSR4 having series diodes D5 ... D8 to prevent discharge of commutating capacitors C1, C2 through the load. Output filter and current limiting.-Harmonics in the output are removed by means of a series circuit L1, C1 (Fig. 7) tuned to the output frequency and a parallel tuned circuit (Fig. 6, not shown) across the load. A further series circuit, tuned to the third harmonic, may also be connected across the load. In the event of excessive load current, the diac breaks down, triggering a triac which minimizes load current by connecting inductor L2 across part of the series circuit C1. Starting circuit.-Fig. 11 shows a diode pump D1, D2, C1, C2 which counts inverter trigger pulses and, after a predetermined number, triggers a programmed unijunction transistor PUT1 which turns on a thyristor CSR1 supplying power to the inverter driver. Stop circuit.-Fig. 12 shows a circuit for monitoring a trapezoidal wave from the A.C.- D.C. converter. In the event of supply failure, transistor T1 becomes turned off, allowing capacitor C1 to charge sufficiently to turn on unijunction transistor UJ1 which triggers a thyristor CSR1 so as to apply a clamp to the D.C. side, preventing application of power to the inverter until the D.C. filter has completely discharged. This circuit prevents possible commutation failure in the inverter due to low voltage operation. (For Figures see next page.)
