Title: Improvements in electrical systems of remote control
IPC: H02J13/00
Filed: 1939-03-21
Abstract: 526,575. Signalling over power circuits. GENERAL ELECTRIC CO., Ltd., COLLYER, J. E., and SMART, N. C. March 21, 1939, No. 8907. [Class 40 (iv)] In a system of the type described in Specification 500,138, [Group XXXVIII], in which control currents for operating consuming devices are superimposed on the low tension side of a power transformer 14 by an amplifier 11 which is fed over a pilot line 7 from the generator 2, on failure of the pilot line the amplifier 11 is arranged to be fed from local oscillations 18 which are brought into use either automatically or manually. As shown, control current is applied to the pilot line 7 upon operation of a switch 5, which controls relay ST, and one of switches 28-31 which determine the frequency. Relay A responds, connecting up the amplifier 11 and removing a shunt from the secondary of the transformer 13. Relay ST opens a direct current circuit which normally exists for relays B, D over the line 7. If the pilot line breaks, both A and B will be inoperative, and a slow-acting relay BA pulls up, followed by Z, permitting the amplifier 11 to be fed from local oscillators 18 through an amplifier 17 if necessary. The relapse of relay D lights a lamp 6 at the control station. The various oscillators 18 are connected up by relays G-K, which are controlled by manual switches 23-26, and a relay L in series therewith starts the oscillators and amplifier 17 through relays X, Y. The time of emission is measured by a time switch 22, which after one rotation of a cam 34 restores the operated relays, or by a slow-acting relay, for example, of the kind described in Specification 491,980, [Group XXXVII], connected to the network 16. Relays G, H may also be controlled by clock contacts over wires 20, 21. The local generators may be brought in service manually by means of a switch having contacts 9, 27, and in this case the clock control over wires 20, 21 is disabled. Alternatively, the local generators and associated relays may be arranged as a portable unit which is plugged into a jack 10 when required. As a modification, the amplifier 17, when used, may replace the normal amplifier 11 and feed the transformer 13 directly.

Patent GB-385588-A (GB)
Title: Improvements relating to centrifugal machines for drying pulpy material
IPC: B04B3/00
Filed: 1931-03-24
Abstract: 385,588. Centrifugal extractors. HEINZELMANN, H., 29, Giesserstrasse, Winterthur, Switzerland. March 24, 1931, No. 9004. Convention date, April 12, 1930. Void [Published under Sect. 91 of the Acts]. [Class 23.] A centrifugal machine for drying pulpy material has devices which exert a braking action against centrifugal force on the material during the first part of the drying process, and after part of the liquid has been expelled the remainder of the material is assisted through the drum by feeding devices. The outer drum 1 is carried by the shaft 5 while the inner drum 8 is secured to the shaft 12. The shafts are driven in the same direction at different speeds by means of the belt pulleys 6, 13. The drum 1 has a conical part 23 inclined to the axis at an angle greater than the angle of repose of the material for treatment, and a part 24 inclined at an angle less than the angle of repose. The part 23 has annular channels 35 covered by sieves 37 and having outlet openings 36. The part 24 consists of three sections I, II, III the inclination of each being opposite to that of the part as a whole. At the peripheries of the sections, openings covered by sieves 39 have outlets 40. The part 25 of the drum 8 has blades 27, 28, 29 shaped as shown in Fig. 2, and the part 26 carries pivoted plough blades 30 with balance weights 32 and adjustable setscrews 33. The interior of the drum 8 may be divided into two chambers by a transverse partition 34. The material to be dried is passed through the funnel 22 and shaft 5 to the space between the drums 1, 8 where it is moved outwards by centrifugal force. The shapes of the blades 27, 28, 29 retard its outward movement during the first part of the drying process and the expelled liquid passes through the sieves 37 to the casing. The material then passes to the section I of the drum 1 and separated liquid passes through the sieves 39, in a direction opposite to that in which the centrifugal force is acting, to the discharge outlets 40 ; with this arrangement the solids do not clog the sieve. With the assistance of the ploughs 30 the material passes on to sections II, III and the collector 51. A liquid for washing or otherwise treating the material can be passed through the pipe 21 to the interior of the drum 8 from whence it passes by openings 52 to section I. Another liquid may be passed through the pipe 19 to sections II, III. In a modification shown in Fig. 4, the drum part 23 has sieves 37 through which liquid flows into channels 35 and outlets 36. Metal flaps 54 over the sieves 37 form pockets which centrifugal force tends to close, but which the moving material tends to open, After passing the drum part 23, the material. in a partly dried state passes to the perforated drum 24 in which the drying is completed ; its passage through the drum 24 is assisted by blades 56 on the drum 8.

Filed: 1953-04-01
Abstract: 734,147. Milling; chucks. INSTRUMENTS ET OUTILLAGE SOC. ANON. F.I.O. April 1, 1953 [May 7, 1952], No. 9011/53. Class 83 (3). An automatic milling-machine comprises a member 36 which controls the opening and closing of a collet 4, the operation of a workpiece feed device 16, and also the setting of a supporting stop 51 and a gauging stop 61, and a single actuating member 32, 33, which advances work along a tube 9 and disengages the gauging stop 61. In a machine for cutting teeth on a dental milling-cutter blank, Fig. 6, the blanks drop from a shoot 5 into a magazine 16 which is advanced intermittently to position a blank in alignment with the tube 9. The blank is fed into the collet 4 by a rod 31 actuated by the cam 32 on the shaft 34. The collet is opened and closed by cams 35a, 35b on the shaft 34 which oscillate a plate 38 and thereby oscillate the yoke 36. The yoke 36 carries a rod 45 which rocks a lever 47 carrying the bearing stop 51 to support the work 5, a rod 52 to oscillate a pawlcarrier 67 to advance the work-magazine 16, and also a push-rod 56 abutting a member 58 carrying the spring-pressed stop 61. The member 58 also carries a pin 62 engaging a spring-pressed rod 63 which is actuated by a push-rod 66 moved simultaneously with the work-feeding rod 31. In operation, after the tool t has been retracted as described in Specification 734,145, the cams 35a, 35b actuate the yoke 36 to unclamp the work, lower the support 51 and rotate the magazine 16. The cam 32 next, through the cable 33, advances the feedrod 31 and also moves the push-rod 66 to advance the rod 63 and depress the pin 62. The work is thus advanced to engage the stop 61 which, as the rod 31 is subsequently withdrawn, is moved by its spring to its outer limit, thus positioning the work correctly. The yoke 36 is then actuated again to clamp the work, to position the support 51 and to withdraw the stop 61. Indexing.-The work is indexed between cuts by the cam 7 of Specification 734,145 which periodically releases a cable 71 to allow a spring 87 to release locking balls 82, 78 and to retract a pawl 72 engaging an indexing disc 75. When the cable 71 is again tightened, the disc 75 is advanced and the ball 78 is pressed into a recess 77. The mounting of the work-holder may be adjusted angularly according to the angle required on the teeth of the finished cutter.

IPC: B60P3/20
Filed: 1968-02-28
Abstract: 1,198,354. Refrigerators. CRYO-THERM Inc. 28 Feb., 1968, No. 9590/68. Heading F4H. Perishable commodities are cooled during transport in portable containers, trucks, railway cars or ships by a fluid circulating heat transfer system which is arranged to surround the commodities and includes a heat-exchanger cooled to refrigeration temperatures by a cold source, at least the major portion of the heat transfer system being occupied by liquid. As shown in Fig. 1, the heat transfer system comprises interconnected heat exchange plates 13, 14, 15, 16, e.g. of the roll-bonded type, connected by a supply line 29 and a return line 32 to a heatexchanger 23. A coil 26 in the latter is supplied with liquid nitrogen from a vessel 11 under the control of a solenoid valve 35. The heat transfer system is partially filled with a liquid such as alcohol, acetone, carbon tetrachloride or a halogenated hydrocarbon, and in operation acts as a closed condensing-evaporating system. Valve 35 may be thermostatically controlled. The cold-source may alternatively comprise dry-ice (Fig. 6, not shown) or a mechanical refrigeration system. In the embodiment of Fig. 8, the heat transfer system 91 contains a non-evaporating liquid which is circulated by a pump 95 and cooled by direct contact with liquid nitrogen in a cyclone 90. The latter has an outlet tube 102 for nitrogen vapour. The warmed nitrogen vapour may be discharged to atmosphere or supplied to the interior of the container to provide a preservative atmosphere. In the latter case the nitrogen is supplied to a Venturi in which it induces and mixes with a stream of outside air before passing to the enclosure. The incoming air may be cooled by air and nitrogen leaving the enclosure (Figs. 10 and 12, not shown) and gas analysers may be provided for controlling the amounts of air and nitrogen, as well as carbon dioxide from a reservoir, admitted to the enclosure (Fig. 13, not shown).

Title: Transistor signal-translating system
IPC: H03F1/30
Filed: 1958-03-26
Abstract: 870,920. Transistor circuits. HAZELTINE CORPORATION. March 26, 1958 [April 15, 1957], No. 9723/58. Class 40(6) [Also in Group XXXVI] The effects of collector leakage current in a transistor in the conducting condition are reduced by operating both emitter and collector junctions with forward bias so that a forward current flows between collector and base sufficient to swamp the leakage current. In the Figure, when a positive pulse is applied to the circuit from source 17 a capacitor 21 charges and causes the transistor 10 to become non-conductive. Accordingly a capacitor 23 now charges linearly through a resistor 25 to generate the long flank of the saw tooth wave. The charge on capacitor 21 leaks away until the potential at the base reaches a value such that an emitter bias source 15 causes the transistor to conduct and rapidly discharge the capacitor. The value of the circuit parameters are such that when the capacitor is discharged, the transistor is still conducting and a small positive bias appears between collector and base. This causes a forward current to flow between collector and base which swamps variations in circuit performance due to collector leakage current.
