Title: Gyroscopic apparatus
IPC: G01C19/38
Filed: 1955-04-13
Abstract: 798,089. Gyroscopic apparatus. SPERRY RAND CORPORATION. April 13, 1955 '[May 21, 1954], No. 10637/55. Class 97(3) [Also in Group XXXV] A gyroscope rotor bearing case is located in liquid-filled liquid-tight casing and the effective density of the case is made equal to the density of the liquid, after assembly, by adjustment of means forming part of or attached to the case. In Fig. 1 a gyroscope compass comprises a rotor-bearing case 17 movable about a vertical axis through bearings 18, 19 in a gimbal ring 16 movable about a horizontal axis through bearings 13, 14 on a follow-up member 6 movable about a vertical axis relative to a frame 4 by a motor 9 under the control of an E-type pick-off 29 detecting relative angular movement between case 17 and follow-up member 6. Frame 4 is mounted with freedom about mutually perpendicular horizontal axes 3 and 5. The whole apparatus is enclosed in a liquid-filled liquid-tight casing formed by a container 1 having a transparent cover 1<SP>1</SP>. The liquid chosen has a normal density equal to the effective density of case 17 to remove load from bearings 13, 14 which may then be of the jewel type. If, however, these conditions are upset by change of liquid density with change in temperature, casing 17 moves vertically relative to bearings 18, 19 to vary the capacity of a condenser 33, 34 which is connected in a high frequency alternating current bridge circuit (not shown) energizing a spring biased electromagnet 39. The consequent variation in the energization of electromagnet 39 adjusts a bellows 41 to vary the pressure of the liquid so that the size of air-filled flexiblewalled float chambers 45, 45<SP>1</SP> attached to case 17 is altered until load is again removed from bearings 13, 14. To eliminate load on bearings 13, 14 due to ring 16 the latter may either have float chambers attached or may be made of magnesium having the same density as the liquid. Follow-up member 6 carries a dome 48, with compass markings, which also acts as a swirl shield to reduce drag of the liquid. A transmitter 12 for repeater compasses is driven by follow-up member 6. Meridianseeking properties are imparted by liquid containers (not shown) within case 17 and interconnected by a restricted pipe. An eccentric mass 24 is provided for damping purposes. Electrical connections are made to case 17 through mercury caps 25, contacts 26 and torsionless wires 27, 28. In one modification, float chambers attached to case 17 are dispensed with, portions of case 17 being made flexible instead. In another modification the float dhamber are replaced by liquid-filled containers having bleed orifices so that the amount of liquid within varies with the pressure produced by bellows 41. Inductive photo-electric and liquid resistance type pick-offs detecting vertical movement of case 17 are referred to.

Title: Improvements in or relating to transmission-level testing arrangements
Inventor: WARDLE THOMAS PAUL BENTLETT
IPC: H04B3/48
Filed: 1964-03-14
Abstract: 1,001,500. Measuring transmission level. AUTOMATIC TELEPHONE & ELECTRIC CO. Ltd. March 14, 1964, No, 10885/64. Heading G1U. [Also in Division H4] The transmission level characteristic of speech channels between two telephone exchanges EXA and EXB is tested by an arrangement which inter-connects a pair of channels at one exchange EXB and feeds a signal from an audio frequency generator SEO around the two channels and compares the received signal with an upper and a lower reference signal derived from the generator in order to determine whether or not the transmission level characteristic is within permissible limits. Each comparator comprises two rectifier bridges B1, B2 and B3, B4 one supplied with a re reference signal from the generator SFO through alternators P1 or P3 and amplifiers A1 or A3 and the other supplied from the generator SFO, through the exchange apparatus and the channels L, through an alternator P2 and an amplifier A2 and through a transformer T2. The outputs of each pair of rectifier bridges are connected in series opposition and drive transistors TXA, TXB controlling relays arranged so that both relays are actuated if the test result is satisfactory. At the exchange EXA the carrier system terminal equipment CTEA has a plurality of four wire outgoing trunk line relay sets, such as ORS, and the carrier terminal equipment CTEB at the incoming exchange EXB has a corresponding number of four wire incoming trunk line relay sets such as 1RS. Both relay sets are equipped for v.f. signalling and dialling. Each outgoing relay set ORS is accessible over selectors, such as SA, for normal traffic and also over routiner access selectors RAS associated with an automatic routiner incorporating the transmission level testing equipment TTE connected through test distributor TD. The routiner connects a sequence of tests to the pair of channels, and when they are successfully completed it advances to the next relay set. If a test result is not satisfactory the routiner indicates the relay set concerned and the nature of the fault. The exchange EXB is arranged so that when a particular code is received from the routiner an answering circuit loops the go an return pairs. Preferably the code is not imitable by dialling. To cater for inter-exchange links having different nominal transmission levels the alternators P1, P2, P3 are switchable to different valves by switches controlled by the routiner. The invention may be used on inter-exchange routes employing repeatered two way two wire lines, in which case one line is used for "go" and the other for "return" and then conversely.

Title: Improvements in and relating to stuffing boxes for crimping filaments and staple fibres
Inventor: FARMER HAROLD OATRIDGE
IPC: D02G1/12
Filed: 1959-04-01
Abstract: 870,250. Crimping fibres. COURTAULDS Ltd. March 31, 1960 [April 1, 1959], No. 10976/59. Class 120(3) In the operation of a stuffing-box for crimping continuous filaments or staple fibres, a tow or top 16 is fed by rollers 7 and 8 into a tapered, compression chamber formed by plates, as at 2, and side-walls 3 and 4. The internal pressure in the chamber opens a loaded, hinged shutter 5 to allow crimped tow or top 18 to emerge: in sympathy with this action, the loaded wall 4 oscillates about a hinge on the shaft 10 of roller 8, to compensate for the pressure loss during the spasmodic release of tow or top, and thus maintain constant the crimping pressure. The loading weights 12 and/or 14 and/or equivalent springs (not shown) may be adjustable.

Title: Improvements in or relating to printing press ink mist control apparatus
IPC: B41F31/00
Filed: 1965-03-16
Abstract: 1,044,415. Inking apparatus. BROOKHIRST IGRANIC Ltd. March 16, 1965 [March 30, 1964], No. 11102/65. Heading B6C. [Also in Division H2] In an electrostatic arrangement for suppressing ink mist in a printing press and comprising a high voltage conductor adjacent an earthed ink transferring roller of the press, means respond to the occurrence of an arc between the conductor and roller to interrupt the power supply to the conductor to extinguish the arc and, after a timed interval, to restore the power supply. In Fig. 1 the conductors 6 are supplied by a voltage regulating transformer 1PT through a voltage doubling rectifier circuit 15 ...20 when the contacts 1TR1 of a time relay 1TR close with a time delay. In the event of arcing between conductors 6 and earthed rollers, indicated at 7, the current flowing in the secondary circuit of the transformer is sufficient for a control relay 1CR to open its contacts 1CR1. The relay 1TR is de-energized and opens its contacts 1TR1 without delay to interrupt the supply. The relay 1CR then releases and relay 1TR recloses with a time delay to restore the supply. In a modification, Figs. 2 and 3 (not shown), the control relay is connected to the saturating winding 12 of the transformer and effects the interruption of the supply when the voltage across the winding falls due to excessive current in the secondary winding 11 of the transformer. Fig. 5 (not shown) illustrates an arrangement having a stepping switch to finally interrupt the supply after a predetermined number of arcs have occurred. In a further arrangement, Fig. 6 (not shown), the power supply is finally interrupted if arcs occur at a predetermined rate, an increment of charging current being received by a capacitor each time an arc occurs and the supply is interrupted. The capacitor can discharge slowly through a resistor, but if the rate of arc occurrence is high then the capacitor is sufficiently charged to cause a Zener diode or neon glow tube to breakdown so that a relay is operated to prevent automatic restoration of the supply.

Title: Improvements in or relating to process for the production of melamine
Filed: 1943-07-13
Abstract: Melamine is produced by a cyclic process in which dicyandiamide, cyanamide, or a mixture thereof in solution in liquid ammonia is heated for 10 to 60 minutes at 110 to 160 DEG  C. under sufficient pressure to maintain the liquid phase and prevent substantial vaporization of ammonia, whereupon the reaction mixture is cooled, the precipitated melamine is removed and the mother liquor is recycled with or without additional quantities of dicyandiamide and liquid ammonia.  The dicyandiamide is preferably dissolved in the liquid ammonia at about 20-70 DEG  C. and may comprise 25-70 per cent of the whole.  In order to reduce the amount of deamination products formed in the reaction, not more than about one half of the dicyandiamine is converted to melamine during the reaction period. The relatively insoluble melamine is filtered from the cooled reactants which contain the more soluble dicyandiamide and intermediate products in solution.  The process may be carried out in the apparatus of Specification 598,532.
