Title: Logic level translators
IPC: H03K19/018
Filed: 1975-07-01
Abstract: 1520131 Transistor circuits HONEYWELL INFORMATION SYSTEMS Inc 1 July 1975 [1 July 1974] 27676/75 Heading H3T A logic level translator uses a current switch, a current source and a plurality of emitter followers to convert TTL and DTL signal levels into CML and ECL signal levels. The translator provides isolation between the input and output logic earths so that noise in the output is reduced. In the described embodiment T<SP>2</SP>L signals switching between +0À4V (0 level) and +3À5V (1 level) are translated to CML sigals switching between -0À5V and 0V. When the input at 45 is at +0À4V transistor 24 is cut off and the current flow from T<SP>2</SP>L earth to -3À3V supply line through resistors 36, 35 produces a voltage difference between points V3, V4 which turns transistor 27 on and transistor 28 off, producing a voltage drop of 0À5V across resistor 39. When the input at 45 switches to +3À5 V transistor 24 turns on, and the current through the resistance network changes to produce a voltage between V3, V4 which turns transistor 27 off and transistor 28 on, producing zero voltage drop across resistor 39. Where an output for DTL or ECL is required the circuit may be followed by a further emitter follower (14), Fig. 3 (not shown).

Title: Starting circuit for synchronous motor
IPC: H02P1/46
Filed: 1957-09-10
Abstract: 813,087. Control of A.C. motors. COLLINS RADIO CO. Sept. 10, 1957 [Feb. 21. 1957], No. 28555/57. Class 38 (3). A synchronous motor 10 is supplied through an inverter 20 which is controlled by a starting oscillator 15 or a running oscillator 16, the latter having an output frequency related to the desired synchronous speed of the motor, whilst the oscillator 15 provides a higher frequency. The change-over from the oscillator 15 to the oscillator 16 is effected by a relay 18 which responds when the motor voltage reaches a predetermined value during the starting period, corresponding to a suitable value of motor speed. The lower frequency of the running oscillator enables the motor to pull into step since it establishes a synchronous speed which is substantially equal to the actual speed of the motor. The inverter comprises a centre-tapped transformer 29 the primary winding of which is excited at the control frequency, the secondary winding being connected in the grid control circuits of thyratrons 25. Anode current pulses in primary winding 26 induce voltage in secondary winding 31 for supplying the motor. A single oscillator may replace the oscillators 15 and 16, the decrease in frequency being effected by increasing one of the reactive elements in the oscillator, with an unbroken connection being made to the control frequency terminal 19.

Title: Improvements in or relating to rotary filters
IPC: B01D33/00
Filed: 1955-10-10
Abstract: 851,851. Rotary filters. KEENE, E. W. W. Jan. 9, 1957 [Oct. 10, 1955], No. 28735/55. Class 46. The rotor of a rotary filter comprises a rotatable shaft 9, Fig. 2, having centrally mounted thereon a support 14, 15, Fig. 1, carrying filter leaves 22, 23, which overhang the support symmetrically, Fig. 2, to form inner and outer drums with open ends to accommodate scrapers for the filter leaves, (though one drum only need be provided). The support consists of arms 14 tangential to the shaft 9, adjacent arms being crossed, lattice fashion, by shorter arms 15, and the whole being braced by arms 16, 17 mounted on brackets 18, 19 (a, b) respectively on the shaft and secured to the meeting points of the arms 14, 15. These arms support brackets 20, 21, of angle section which carry the overhanging filter leaves 22, 23. Each filter leaf consists of parallel perforated plates 40 spaced apart by V-section struts 36, Fig. 3, and each covered with filter cloth 52 clamped at the inner edge between plates 41, 42. The cloths are also held close to the screens by wire clamps 53, Fig. 6. Rods 47, accommodated between recessed ends 38 of adjacent leaves, retain the filter leaves in their proper relative positions. A tubular stud 45 in each leaf connects the interior of the leaf to a vacuum pipe 33a, communicating with an annular vacuum chamber 34 Figs. 1 and 2, the vacuum drawing liquid from a tank 24, into which the filter dips, into the interior of the leaves. Scrapers 25 ... 28 contact the filter cloths to remove residue which is directed by a guide plate 29 and shoots 30 ... 32 away from the filter. As shown in Fig. 6, a wire scraper 25 is yieldingly pressed against the filter cloth by a counterweight 50 and is guided by a prong 54 having a curved end over the junctions between adjacent filter leaves. Material removed by the scrapers may be broken up by a beater 64 actuated by an eccentric 58, and may be discharged by a screw conveyer 56 instead of a shoot. Alternatively a belt conveyer may be used. The scraper may be replaced by a roller. A quick-release clamping device for the outer edge of a leaf is depicted in Figs. 8-10 (not shown). The rods 47 may be replaced by sealing members for the cloth edges. The raw liquid may be stirred by agitators 66 ... 68, Figs. 1 and 2. The provisional Specification describes and shows inner and outer scrapers guided from one filter leaf to the next by cam washers on the rods 47, the screw conveyer 56 being replaced by a tipping hopper. Specification 519,689 is referred to in the Provisional Specification.
