Abstract: 306,607. Carpmael, A., (I. G. Farbenindustrie AKt.-Ges.). Nov. 18, 1927. Divided on 306, 575. o-Aminomercapto-, o-aminothioglycollic and ocyanothioglycollic-aryl derivatives.-An o-aminoarylsulphocyano compound, in which the position para to the amino group is occupied or forms part of a further ring, prepared for example according to Specifications 257,619 and 303,813, is treated with alkali, preferably in the presence of a reducing agent, so as to saponify the sulphocyano group and form a mercapto group. The latter is coupled with chloracetic acid and the resulting o-aminoarylthioglycollic acid is finally diazotized and subjected to Sandmeyer's reaction in order to obtain an o-cyanoarylthioglycollic acid. In examples, 1-methyl-2-amino-3-sulphocyano-5-chlorbenzene, 1-amino-2-sulphocyano-4- ethoxybenzene and l-sulphocyano-2-aminonaphthalene are used as starting materials, 1-methyl- 2-cyano-5.chlorbenzene-3-thioglycollic acid, 1- cyano-4-ethoxybenzene-2-thioglycollic acid and 2- cyanonaphthalene-1-thioglycollic acid respectively being produced. Specification 11173/06 also is referred to.

Abstract: 1464896 Reel game blinker shutter BALLY MFG CORP 30 Jan 1974 [30 Jan 1973] 04385/74 Heading G4U Reel type game apparatus includes symbol bearing reels e.g. 13, and reel-actuating mechanism operative in game cycles to spin and index the reels to symbol-displaying positions, and shutter means co-operatively disposed relative to a reel and having open and closed conditions, the shutter means including two shutter members 16, 17, coacting to converge and diverge to the closed and open conditions together with a motor 30 actuating and control circuit means to displace the members in said movements for display of a symbol selectively in a steady state open condition or a masked condition, as well as in closely sequential opening and closing, namely blinking, at a predetermined time during a game cycle. Fig. 2 shows linkage for spinning a reel. As a result of handle actuation, the drive shaft 32 is rocked to withdraw the driving lever and pawl 33 abruptly and flip roller 33A out of whatever award notch it happens to have been in and thereby spins the reel. Simultaneously, singing and indexing lever 34 is rocked away from the notched disc until a timing means permits it to move back and stop the disc.

A disc 20 rotatable by motor 30 has studs 21A, 21B mounted thereon to move the levers apart when required. Switches A, B, C, D provide control signals for the shutter mechanism as well as having functions related to the operation of the reel mechanism and award system. Shutter control switches 28, 29 are connected in a motor circuit for actuation co-operatively with master reel-circuit means in such manner as to cause the shutter means to blink open and closed at certain times, to stand open or closed at other times, or be openable at the election of the player at still other times, dependently upon certain reel spinning and award conditions.

Title: Direct current electrical power transmission
IPC: H02J1/00
Filed: 1973-01-29
Abstract: 1388824 HVDC power transmission SIEMENS AG 29 Jan 1973 [29 Jan 1972] 4458/73 Heading H2F In a control system for a HVDC power transmission system, a current controller StR1 for the rectifier GR responds to the difference between desired and actual current in the line L2, the desired current signal Ides being fed via a transmission path FU, NS to the control circuit for the inverter WR, the transmission path imposing a greater delay than the control path via StR1. The system normally operates with constant line voltage, as controlled by regulator SpR but this control may be overridden by a current regulator StR2 as determined by which circuit feeds the more positive control signal into the diode gate A1. If the desired power P des  is to be reduced, controller StR1 acts on the rectifier GR so as to reduce the line current I act . The reduction in I act  has the effect of increasing the output of current controller StR2 so that this controller takes command so as to reduce the conduction angle of inverter WR which temporarily reduces the line voltage and tends to increase the line current. When the signal Ides has passed the transmission path FU, NS, a new desired signal reaches controller StR2 which reduces its output so that the voltage controller SpR again takes over so that the reduced power is transmitted at the same voltage but with reduced current. As described the desired power signal P des  may be fed into a divider DG which produces Ides by dividing P des  by the line voltage U act.  The transmission device FU may handle a digital signal which is converted at DA to analogue so as to drive a motor M controlling a potentiometer P2 so as to provide a new value of I des . The system may operate with a current margin Il injected into a subtractor DE. Minimum and maximum angles for inverter WR may be controlled by signals A21 and A11.

Title: Improvements in garbonizing chambers,retorts,furnaces and the like.
Inventor: THOMAS OLIVER
IPC: C10B7/08

Abstract: 378,848. Drying solid materials. THOMAS, O., St. Aubins, Erith Road, Bexley Heath, Kent, and KEMP, A. V., Red Cottage, Pinner, Middlesex. Feb. 16, 1931, No. 4786. [Class 34 (ii).] In the drying of solid materials such as coal or shale, the material is passed continuously or intermittently through a heated chamber, the gases or vapours evolved escaping through outlets spaced away from the chamber walls, and the material during its passage through the chamber is maintained in a series of separate charges each consisting of a predetermined quantity. The material is fed in regulated quantities from a hopper 42 on to pans 26 fixed to an endless chain 24 mounted on tumbler guide wheels 20, 22, a driving shaft 21 causing the pans to pass downwardly through a leg 1, and upwardly through a leg 2. The material is compressed as each pan passes over the upper guide wheel 20 into a horizontal position in the leg 1, and is discharged when the pans separate on passing round the lower guide wheel 22, falling into the discharge hopper 14. The legs 1, 2 are externally heated by flues 9. The distillates are withdrawn through apertures in a duct 29 which is placed centrally in leg 1, or may, in a modification, be withdrawn through holes in the links supporting the pans. Pricker bars 41 may be provided to press into each of the separate charges, and form lines of weakness in the compressed charges, so that they break easily into pieces of predetermined dimensions when discharged. When the material is charged through an inlet 46, and subjected to a preheating treatment in leg 2, a hopper 42a may be used to add more material to form a mixture which is subsequently heated in leg 1. The gas withdrawal ducts are provided with cleaning means 33, and issue either upwardly or downwardly, and may be situated adjacent a heated wall so that the outgoing gases may be heated. The apparatus may be operated by gravity, in which case the rotation of the wheels 21, 20 are controlled by bank brakes. Knockers 52 may be arranged on the tumbler wheels to consolidate the charge at the top or to facilitate discharge at the bottom. In a modification three legs are employed, the pans passing upwardly through the two outside legs and downwardly through the inside leg common to both sets of pans.
