Title: Circuit arrangement for telecommunication, particularly telephone installations withdirect-current feed of the subscriber's stations
IPC: H04M3/22
Filed: 1966-03-03
Abstract: 1,092,975. Automatic exchange systems; transistor switching circuits. TELEFUNKEN PATENTVERWERTUNGS G.m.b.H. March 3, 1966 [March 3, 1965], No. 9380/66. Heading H3T and H4K. A subscriber's line circuit feeds the line with D.C. over a transformer OLU and transistor T1 which becomes conducting when the loop is closed, and a second transistor T2 having negative feedback by way of a capacitor C and threshold diode Z responds to dialling and supervisory conditions. The transistor T2, normally conducting, is cut off when T1 responds to the closure of the loop and capacitor C charges to reduce the potential at point B as indicated at D, Fig. 2. In response to dial impulses, the base current of T2 increases and it acts as a Miller integrator, giving the effect shown at E, Fig. 2. When release occurs, integration continues until point A reaches zero potential, G, Fig. 2. Transistors T3, T4 which are differently biased respond to dialling release conditions.

Title: Arrangement for pneumatic operation of electrical circuit breakers
IPC: H01H33/12
Filed: 1943-06-15
Abstract: 564,949. Gas-blast switches. GORDON, H. H. (Allmanna Svenska Elektriska Aktiebolaget). June 15, 1943, No. 9516. [A Specification was laid open to inspection under Sect. 91 of the Acts, Nov. 30, 1943.] [Class 38 (v)] In order that the contacts of a pneumaticallyactuated, gas-blast switch shall not open until the full gas-pressure is available for quenching the arc, the gas is initially admitted to both sides of the contact-operating piston, so that the full pressure is available at the contacts, whereupon the space behind the piston is exhausted to enable contact-separation to take place. In a double-break arrangement provided with an isolator 6, 7, spherical movable contacts 17, 18 co-operating with nozzle-shaped fixed contacts 15, 16 are operated by pistons 21, 22 in cylinders 23, 24, which intercommunicate via orifice 27 so that when the blast valve 2 and valve 3 are, opened to break the circuit, gas is available on both sides of both pistons, the valve 3 being then moved to exhaust the two cylinders to atmosphere and allow the contacts 17, 18 to open. When piston 22 moves past orifice 27, the spring 25 recloses contact 17, leaving 16 open while the valve 3 is open to atmosphere. The break 17, 15 is shunted by a resistance 30 so that the break 16, 18 has only a reduced current to open and nozzle 16 is accordingly reduced. Cylinders 23, 24 are carried on insulator 29 on the metal cap 13 supporting contact 15, the cap 13 being mounted on an insulator 12 on a metal case 10 on a further insulator 11.

Title: New or improved process and apparatus for the drying of grain, seed or the like in bulk
IPC: F26B3/00
Filed: 1945-07-18
Abstract: 595,400. Drying grain, seeds, &c. EVANS, C. H. July 18, 1945, No. 9633/44. [Class 58] [Also in Group XIII] . Grain, seed, &c. in bulk is dried by the passage therethrough of air which is at or near atmospheric temperature and the relatively humidity of which is so controlled, by removal, of excess moisture, as to vary in direct relation to the length of path of travel of the air through the grain from a minimum value of 30 per cent for short air paths, say 3 feet, to a maximum of 70 per cent for long paths of 15 feet or more. An installation comprising three drying bins 20, 21, 22 with associated air fan 10 and drier 11, the latter preferably a pair of drums each containing silica gel, is shown in Fig. 3. Air from the fan 10 passes alternatively through one of the driers 11 from whence it is led, together with atmospheric air supplied through a valvecontrolled pipe 12, through a main valve 13 and auxiliary valves 14, 15, 16 to vertical channels 17, 18, 19 extending down the sides of and communicating with the bins 20, 21, 22 respectively, the air, after passage through the grain, being exhausted through opposed vertical channels 23, 24, 25 and then either vented to atmosphere by the pipe 28 or else returned to the fan by a pipe 26 provided with a filter 27. The valve 13 is such that the direction of flow through the bins may be reversed, and it may be controlled, also the valves 14, 15, 16, by an automatic device 29. A portable drying apparatus is also described. Specification 140,837, [Class 58], is referred to.

Title: Improvements in or relating to the manufacture of yarn from textile staple fibres

Abstract: 1,218,162. Break spinning. VYZKUMNY USTAV BAVLNARSKY. 24 Feb., 1969 [28 Feb., 1968], No. 9672/69. Heading DID. In a break-spinning process, the yarn, after leaving the spinning member passes through a zone in which the axial tension of the yarn is increased to permanently deform the yarn i.e. it is drafted. To effect the draft a braking device may be provided upstream of the withdrawing rollers. The braking device may comprise a rod about which the yarn is wrapped, a pair of notched rods 211, about which the yarn passes and by rotation of which the tension applied to the yarn can be adjusted, a helical tube 203 or a tube 201 having a serpentine bore and attached directly to the spinning chamber. In other forms the yarn may be passed in serpentine manner between two sets of rods, one set of rods being movable relative to the other to (a) adjust the tension and (b) disengage from the yarn path on breakage. The sets of rods may be relatively biassed so that on yarn breakage one set moves to operate a contact and close an electrical circuit, thus the tension device also acts as a thread breakage detection. Alternatively a separate thread feeler is provided to detect breakages. In a further form, Fig. 15 not shown, the yarn, after leaving the spinning member runs through two pairs of rollers, the second pair having a higher peripheral speed than the first pair.

Abstract: 942,949. Force-feed lubricating. STEWART-WARNER CORPORATION. March 18, 1960 [March 20, 1959], No. 9752/60. Heading F2A. A lubrication unit includes a reservoir 10 for lubricant and a pump 16 coupled to a driving shaft 68 to pump lubricant from the reservoir to a supply passage 14, a by-pass line 26 connecting the passage 14 to the reservoir and a valve 28 operated from the driving shaft periodically to permit the pump to increase the pressure in the passage 14, the pressure in the passage 14 acting on the valve 28 but being substantially balanced so as not to tend strongly to open or close the valve. The pump shaft 68 drives a cam 118 through gearing 104, 106, 108 to close the valve periodically through a follower 150 and a spring 154 which permits the valve to lift to relieve excessive increase of pressure until a pin 156 engages the upper end of a transverse bore in the follower. The reservoir includes a flexible cover 52 and a resilient diaphragm 58 and is charged through an aperture 50 from a supply valve 84 in the wall of the unit. A closure land 124 on the valve 28 has a slightly larger area than a lower land 126 to provide a small upward force due to fluid pressure in the passage 14 which supplies the parts to be lubricated through measuring valves opened by the pressure rise when valve 28 is closed.
