Abstract: 536,425. Electric control systems. RANSOMES & RAPIER, Ltd., and SNELL, M. H. Nov. 11, 1939, No. 29880. [Class 40 (i)] Electric sluice-control gear comprises a motor-operated sluice gate and a control carrier which reproduces the movement of 'the gate on a small scale and co-operates with means responsive to variation in the liquid level to control the circuit of the motor whereby the level is maintained substantially constant. As shown in Fig. 3, the gate A is operated by rope-hauling gear B which carries a small winding drum B2 connected by rope B1 to the switch carrier K. The switches L, L1 for lowering and lifting are controlled by arm H4 on the rod of a float H1 operating in a well H3, the switches being operated through adjustable abutments on rockers. The motor circuit is opened by a stop switch operated by a cam on the winding drum after the gate has been moved say 2 inches unless one of the switches L, L1 is still closed. The drum B2 may be.of cam form to effect quick movement of the carrier over a portion of its travel. In another arrangement, Fig. 1 (not shown), the carrier is geared to the handling drum by bevel gear and has a stop switch arranged between the reversing switches but nearer the lower one in order to minimize hunting. The circuits of the motor may, alternatively, be controlled by two pairs of electrodes V1, V2, Fig. 2 connected to a geardriven carrier D. The control may be exercised by the upstream or downstream level.

Title: Monophonic-Stereophonic Automatic Switching and Demodulator Circuit
Inventor: FISH LAWRENCE WILLIAM
IPC: H03D1/22
Filed: 1966-07-04
Abstract: 1,157,674. Stereophonic radio receivers. H. H. SCOTT Inc. 4 July, 1966, No. 29915/66. Heading H4L. In a radio receiver, automatic switching from monophonic to stereophonic reception is provided by switching the stereo demodulator diodes under the control of a trigger circuit. As shown, the composite signal from F.M. tuner 2 is supplied to filters 6, 8 and 12. Filter 6 selects any noise above the modulation frequencies, filter 8 passes the composite signal, and filter 12 selects the 19 kc/s. pilot signal which is amplified at 16 and controls an oscillator 20 re-constituting the 30 kc/s. subcarrier. Assuming that stereophonic signals are received, an output from filter 8 is applied to the stereo demodulator 14, the diodes D 1 , D<SP>1</SP> 1  and D 2 , D<SP>1</SP> 2  being switched in conventional manner by the 38 kc/s. subcarrier to provide the left and right signals at terminals 11, 11<SP>1</SP> respectively. A portion of the tuner output fed via adjustable resistors R<SP>11</SP> 1 , R<SP>11</SP> 2  ensures complete separation of the two signals. The output of amplifier 16 is rectified at 22 and supplied as bias to cut off the trigger 3 such as a normally conducting amplifier, so that with the switches S 1 , S<SP>1</SP> 1  in the automatic position, as shown, the voltage from trigger 3 is at earth potential whereby the oscillator 20 operates to supply the subcarrier and no D.C. bias is supplied via resistor R 7  to the demodulator diodes. A neon device N indicates when a stereophonic programme is being received. When monophonic signals are received there will be no output from amplifier 16 or rectifier 22 and the output of trigger 3 cuts off oscillator 20 and via R 7  biases diodes D 1 , D<SP>1</SP> 2  to be fully conductive and diodes D<SP>1</SP> 1 , D 2  to be non-conductive. Thus the monophonic signals are supplied via conductor 8<SP>1</SP> and capacitors C 1 , C 2  to the output terminals. Similar biasing arrangements are provided with the switch in the manual position. The stage 3 is also used as an amplifier for noise from filter 6 to ensure that the receiver operates in the monophonic connection during tuning or when tuned to a weak stereophonic station. The noise output is rectified at 25 and cuts off amplifier 16.

Title: Improvements in automatic motor control apparatus
IPC: G05F1/32
Filed: 1950-12-07
Abstract: 710,178. Control of A.C. motors. FOSTER TRANSFORMERS & SWITCHGEAR, Ltd., and JENNINGS, R. E. Dec. 7, 1951 [Dec. 7, 1950; July 16, 1951], Nos. 29965/50 and 16781/51. Class 38(3) [Also in Groups XXXV and XXXIX] The reversible split field A.C. motor of an automatic tap changer is controlled by two saturable reactors, one in series with each winding. The tapping on an auto-transformer T, Fig. 3, is controlled by a twin field capacitor motor 4. The motor windings are connected through the A.C. windings of saturable reactors 2 and 3 to the output of transformer T via a transformer 1. Reversely connected rectifiers 11, 12, provide a measure of self excitation. Bias windings 7, 8, are supplied via a rectifier 192 from a substantially constant voltage source consisting of an air gapped inductor 36 in parallel with a condenser 37. The control windings 9, 10 are supplied via a rectifier 191 from the output voltage of the transformer T. A saturated closed iron-core reactor 33 is included in this circuit and dimensioned so that at the standard regulated voltage the rate of change of current with frequency in the one rectifier is substantially equal to the change in the other, thus cancelling errors due to changes in frequency. The currents in the bias windings 7, 8, are adjusted by resistors 17, 18 so that the effective ampere turns lie respectively above and below the ampere turns exerted by the control windings 9, 10 under normal voltage conditions. In each reactor the flux due to the control winding opposes that of the bias winding, the differences, however, being of opposite sense in each reactor. Hence if the control voltage rises above the normal value, reactor 3 tends to become more saturated whilst reactor 2 becomes less saturated and the motor 4 will run in the direction to reduce the voltage. The reverse happens if the voltage falls below normal. In a modification, Fig. 1 (not shown), bias winding rectifier 192 is fed through a ballast reactor with linear characteristics, and the control winding rectifier 191 is fed through a closed core reactor operated at or beyond saturation in series with a condenser and a resistor all proportioned so that the A.C. voltage-current curve includes a steep portion centred about the standard voltage. In a further modification, the control windings are fed via a siliconcarbide resistor from the output of a main supply rectifier fed by the tapped transformer, or from the output of a D.C. generator, the field regulator of which is being actuated by the motor. In a still further modification, Fig. 4, the motor 4 is a split-field series motor fed from a centre tapped transformer 41 through reactors 2, 3 controlled as above. A transformer 42 connected across the motor armature injects an antihunting voltage into the system. In a further modification, Fig. 5 (not shown), the anti-hunting transformer is connected across a twin field capacitor-motor. It is also stated that the motor may actuate the field regulator of an A.C. generator, or control the current in an unspecified system.

Headings F1E, F1G, F1J and F1L. A jet propulsion unit or gas generator comprises at least one Venturi tube 4 which is heated, at least at starting, by gases from a combustion chamber 5, and a jet type compressor having a nozzle 2 which entrains air into a duct 1, the air passing through the tube 4 to issue through a nozzle 8. An electric element 14 may provide additional heating. It is stated that heat absorbed by the walls of the tube 4 from the gas is conducted through the walls to heat the gas as it expands. The walls may be sodium filled (at 16a), Fig. 2 (not shown), to improve this conduction. A turbine 11 may provide useful power and may drive a rotary compressor stage upstream of the jet compressor. The nozzle 2 of the latter is supplied with inducing gas from the region downstream of the tube 4 through a pipe 9 having a control valve 9a and an inlet 12 for compressed air at starting. Alternatively, inducing gas may be supplied from a gas generator through a pipe 3. In a modification, Fig. 2 (not shown), the jet compressor has two stages, the nozzles (2', 2a) of which are supplied with inducing gas through a pipe (9'), as before. Some of the working gas may be tapped off from the inlet duct 1 through pipes (21) having control valves (23) to auxiliary propulsion nozzles (22). Fuel oil may be injected (at 15) downstream of the Venturi throat for combustion. In a further modification, Fig. 2 (upper half), the Venturi tube is replaced by a chamber having a converging inlet.

Title: Improvements in or relating to hat finishing machines
IPC: A42C1/08
Filed: 1954-10-20
Abstract: 760,454. Hat finishing machines. DORAN BROS., Inc. Oct. 20, 1954 [Oct. 22, 1953], No. 30210/54. Class 63. Relates to a hat finishing, e.g. pouncing machine in which the finishing tool 24, Fig. 1, is so arranged with respect to the rotating hat block 17 that in traversing the hat crown horizontally from adjacent the tip to the brim and back again, the tool 24 is engaged only once with the tip. The finishing tool 24, e.g. an abrasive pad, is mounted on an arm 20 pivotable about a vertical axis A and is swingable toward and away from the hat block 17 about a horizontal axis B through the co-action of a fixed cam 30 arcuately disposed about the axis A and a cam follower 31 mounted on an arm 29 connected to the arm 20 as described in Specification 484,344. A movable cam 32, Figs. 1 and 4, is pivoted to the cam 30 on a vertical axis C and on movement of the cam follower 31 along the arcuate cam 30, a striker arm 34 movable with the follower 31, swings the cam 32 to a position overlying the cam 30 so that on return movement of the follower 31 it rides over the cam 32 and thereupon swings it to the inoperative position. The path traced by the tool 24 during one reciprocating movement of the follower 31 over the cam 30 is shown in Figs. 2 and 3. Thus during the clockwise movement with the movable cam 32 overlying the cam 30, the tool 24 first engages the hat at a point 18c Fig. 2 beyond the tip 18a and moves down to the brim during which movement the cam 32 is swung away from the cam 30. On moving back in a clockwise direction the follower 31 rides over the cam 30 only and the tool 24 remains in contact with the hat until it reaches the position 24d Fig. 3 in contact with-the tip 18a where the cam 30 ensures that it is immediately moved out of contact with the hat. In Figs. 10 and 11, (not shown) the cam 32 is reversed and so arranged that the clockwise movement of the tool 24 is as shown in Fig 3 and the anticlockwise movement as shown in Fig. 2. Instead of a pouncing tool, the tool 24 may be a greasing pad or ragging tool. Specifications 462,413, 582,406 and 538,042 also are referred to.

Filed: 1928-10-22
Abstract: 299,327. I. G. Farbenindustrie Akt.- Ges. Oct. 22, 1927, [Convention date]. Halogen arylthioglycollic acids are obtained from primary aromatic amines having a free para position and at least one free ortho position by introducing a sulphocyano group into the para position by treating with an inorganic sulphocyanate and a halogen, saponifying the sulphocyano group to form a mercapto group, converting the latter by condensation with chloracetic acid with a thioglycollic acid group and finally replacing the amino group by halogen by Sandmeyer's reaction. According to examples, m-toluidine,1- methyl-2-amino-4-chlorbenzene and p-xylidine are subjected to the above series of reactions, 2- methyl-4-chlor-2 : 4-dichlor-5-methyl- and 2 :5- dimethyl-4-chlor-1-thioglycollic acids, respectively, being produced. Bromine and sodium thiocyanate in methyl alcoholic solution are used for the introduction of the sulphocyano group and the latter is saponified with alkali in the presence of a reducing agent. The process may be modified by effecting the Sandmeyer reaction before the sulphocyano group is saponified. In an example of this method, p-xylidine is treated with sodium sulphocyanate and bromine in methyl alcoholic solution, the amino group replaced by chlorine, and the sulphocyano group saponified and condensed with chloracetic acid, giving the 2 : 5- dimethyl-4-chlor-1-thioglycollic acid. Specification 257,619 is referred to. The Specification as open to inspection under Sect. 91 (3) (a) comprises also the production of halogen aryl thioglycollic acids from any primary aromatic amine having a free para position. This subject-matter does not appear in the Specification as accepted.
