Abstract: 1375840 Hydraulic control circuits MONSUN-TISON AB 21 Oct 1971 10609/71 Heading F1P A circuit for controlling several hydraulic motors and pumps 5, either singly or several at the same time, comprises a variable delivery pump 1 delivering through a line 2 to several distributing spool valves 4 arranged in parallel and each associated with one motor or pump and each controlled by a signal X 1 , X 2  &c. whereby the speed and direction of the associated motor or pump is independent of the pressure drop across the valve. Each valve unloads the source when its associated pump or motor is not in operation. Any valve controlling a motor has means for sensing the pressure in the supply pipe between the valve and the motor and all the valves have means for sensing the pressure in the pipes connecting them to the sump. The pump 1 is regulated, according to the pressures sensed at the valves, by application of a signal Xs, whereby the flow-rate to any motor cannot fall below 90% of the rate corresponding to the rate through the associated valve 4 when the latter is subjected to a specified operating force X 1 , X 2  &c., and the system pressure is prevented from exceeding the highest pressure demand of one or more motors being actuated, and in the case of a pump the system pressure is prevented from exceeding the sump pressure by more than the pressure drop across the lines and valves. Hydraulic or electric control may be used.

Filed: 1928-04-12
Abstract: 320,387. Dunlop Rubber Co., Ltd., Trobridge, G. W., and Murphy, E. A. April 12, 1928. Right to Grant relinquished. Moulding by dipping; moulding indiarubber, resins, or other organic materials. - Shaped articles are formed from aqueous dispersion of organic materials, particularly rubber, by repeated dipping, spreading, or pouring operations to form more than one substantially adhering fluid layer upon non-porous, chemically inactive deposition strata and effecting the setting and drying of each fluid layer by heat applied to that side of the fluid adjacent to the deposition strata prior to the deposition of the next fluid layer. For example, a hollow, non-porous former of glass, glazed porcelain, ebonite, zinc, aluminium, &c. is dipped into the dispersion and, upon removal, is immediately inverted to avoid formation of a drop and then re-inverted. The layer is then dried by circulating a hot fluid, e.g. water, oil, air, or steam through the former, after which the former is allowed to cool or is artificially cooled and the process repeated. The rate of drying is controlled by suitably adjusting the temperature and humidity of the air surrounding the former. In a modification, the layer is deposited upon the interior of non-porous moulds. Successive dippings may be in different dispersions to obtain glazed or multi-coloured effects. compound dispersions as described in Specification 290,313 may be employed; also dispersions of casein, albumen, cellulose esters, natural or artificial resin, &c., alone or admixed. A bottle teat is produced from an ammonia preserved rubber latex concentrated to contain 60 grams total solids and 0.03 grams ammonia per 100 ccs.; the composition of the dry mixing being rubber latex 100 parts by weight, sulphur 2, parts, transformer oil 5 parts and zinc diethyldithiocarbamate 1 part. A hollow glass former is employed and ten layers are deposited, drying being effected at 95-100‹ C. by hot water. The deposit is rolled to form the teat base and cured by immersion in boiling water for one hour. Specification 303,546 also is referred to.

Abstract: 1461169 Copying by scanning G WESTERBERG 11 March 1974 10820/74 Heading H4F A photo-sensitive layer 141, Fig. 1, on a glass plate 14 is scanned by radiation from a radiation source focused thereon by a lens 13 by relatively rapid reciprocating movement of a first slide 11 carrying the lens 13 and relatively slow movement at right-angles thereto of a second slide 12 carrying the plate 14. Alternatively the second slide 12 may be reciprocated rapidly and the first slide 11 may be moved slowly. An acousto-optical modulator (403, Fig. 8, not shown) may be included to intensity modulate the radiation beam and may also deflect this beam at right-angles to the line scan direction so that lines may be recorded between already recorded lines, or so as to replace each line by a densely zig-zag line, or to record several lines at a time. To check a recorded plate 14, the plate is scanned by uniform intensity radiation, one or more photodetectors (71, 73, Fig. 4; 74, 75, Fig. 7, not shown) being provided to detect the radiation transmitted or reflected by the plate. A laser interferometer including a prism 16 attached to the first slide 11 may be included to determine the position of this slide and control the application of signals to the modulator. In the embodiment shown beams 20 and 18 are spring-biased towards slides 12 and 11 respectively; in an alternative embodiment (Figs. 4-6, not shown) each of the beams 17-20 is provided with a replaceable rib abutting bearings supported in V-grooves in the ribs and slides, two of these ribs being spring-biased towards the respective slides.

Abstract: 1,101,891. Supply systems for consumption apparatus. ETABLISSEMENTS GERARD MANG. 15 March, 1965 [17 March, 1964], No. 10852/65. Heading H2H. [Also in Division H3] An electronic time-switch comprises a bistable relay RP, initially energized so as to close a circuit to a load and to a timer comprising a capacitor, the load circuit remaining closed until the capacitor has charged sufficiently to break down a gas-filled discharge tube when an auxiliary relay becomes energized so as to re-energize the bi-stable relay and open the load contacts. As shown, bi-stable relay RP is initially energized by closing pushbutton BP so the load circuit U is energized from A.C. mains D 1  via contacts RP 1 . Capacitor C now charges via rectifier S and resistors P, R I  until a neon discharge tube L breaks down, when an auxiliary relay RX becomes energized, re-energizing the bi-stable relay RP so as to open the load contacts RP 1  and close contacts RP 2  which discharge the capacitor C. Contacts RP 4  are open during the timing period so that the timing is unaffected by further operations of BP. In Fig. 4 (not shown), the contacts are arranged so that subsequent depression of the push-button during a timing period will discharge capacitor C and initiate a further period of the predetermined time. In Fig. 1 (not shown), an auxiliary switch is provided, closure of which enables the load to be energized by the first operation of the pushbutton and de-energized by the second operation. The invention is applicable to control of lighting on staircases.

Filed: 1928-04-13
Abstract: 289,054. Moneyron, M. April 21, 1927, [Convention date]. Rotary transformers; dynamos, regulating.-A constant-power output transformer for converting polyphase currents into single-phase currents or into polyphase currents for supplying separate apparatus, and especially electric arc devices, consists of primary and secondary windings, such as 2, 3, Fig. 1, the turns of which offer different linking areas to the flux and a damping winding, the main and damping windings being wound on two concentric iron structures relatively rotatable. The rotating member carries the damping winding and may be excited with continuous-current from an outside source 7. Fig. 4 shows the difference in coil areas obtained by prolonging the primary coil 2 beyond one side of the secondary winding 3, both coils being mounted in a. magnetic frame 8 which surrounds an H-shaped twopole rotor 4 having a magnetizing coil and a squirrel-cage winding or copper sheath at. its polar surfaces. The effect under load of the large reluctance of the flux path 17 in the primary side 2 on the smaller-reluctance flux path 16 is explained in the Specification. the result being a practically constant power consumption in the arc. Fig. 7 shows an auto-transformer connection on the three-phase side only. the machine in this case being made with short turns 30, Fig. 8, corresponding with the tapped turns 28 and with long turns 29 corresponding to the other turns of that phase. The primary and secondary windings may occupy the same slots or be arranged in separate slots at. either a common or different raidial depth. To allow variation in the secondary currents, e.g. for fusing electrodes of different sizes, the primary flux may be varied by altering the number of primary turns. Or, as shown in Fig. 13, movable pairs of concentric iron rings 34, 35 and 36, 37 may be traversed axially with regard to the protective ends of the long-turn primary coils. A form is also described in which a single iron ring is moved axially with respect to primary coils which project unilaterally along the machine axis, as shown in Fig. 4. Fig. 16 shows a form in which the secondary windings consist of a fixed part 3 and a movable part 39 in series, the part 39 having the same action on the primary flux as the movable iron rings have. The Specification as open to inspection under Sect. 91 (3) (a) states that the invention comprises also the transformation of single-phase current to single-phase current and that the rotor of the transformer may carry the primary and secondary windings while the stator carries the damping windings in place of the converse arrangement shown. This subject-matter does not appear in the Specification as accepted.

Abstract: 919,556. Automatic control of aircraft. BENDIX CORPORATION. March 29, 1960 [April 10, 1959], No. 11074/60. Class 38 (4). A servomotor operating a control surface of an aircraft is disabled automatically when a signal dependent on angular rate of movement of the control surface attains a predetermined magnitude. In Fig. 1, A.C. signals produced (a) by a generator 39 responsive to rate of turn of an aircraft control surface 3, (b) by a pick-off 35 associated with an accelerometer 31 measuring acceleration of the aircraft normal to its flight direction and (c) by a pick-off 23 associated with a gyro 19 measuring rate of turn of the aircraft and modified by airspeed meter 29 are added together so that excessive signals are effective to energize a relay 17 and disable a servomotor 1 which normally adjusts the control surface in response to signals from an automatic, pilot 7. In modifications the control surface is operated by an hydraulic servomotor which is disabled by electromagnetic operation of a by-pass valveassociated with the servomotor control system. In these cases, instead of the signals from generator 39, signals may be derived from (a) a gyro mounted on the control surface or (b) filtering position feed-back signals. Signals dependent on variations of the fluid pressure applied to the hydraulic servomotor may also be added.

Abstract: 1,068,771. Radio signalling; monitoring transmitters. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. Dec. 30, 1963 [March 20, 1963], No. 11083/63. Heading H4L. In an arrangement for monitoring a transmitter 1, Figs. 2a, 2b, at a remote receiver 5, the transmitter is arranged to be switched on and off in repeated succession by a transistor 3 or alternatively by a silicon controlled rectifier controlled by a multivibrator 10, the conducting period of the device 3 being substantially shorter than the non-conducting. At the receiver a detector 6 supplies a relay 7 (preferably electronic) which has a quick response but remains operated for a limited period beyond the " off " period of the transmitter so that while the push-button 8 is open the relay 7 will remain operated, but if a failure occurs it will release and operate an audible or visible signal. A normally open contact relay 9 operates only after a delay longer than the duration of each pulse so that when the switch 8 is open the contacts of relay 9 remain open. When switch 8 is closed the relay 9 operates and may connect a receiver for speech or other signals. Alternatively coded signals may be transmitted by operating the switch 8. In a modification the relay 9 is dispensed with and the switch 8 is connected in series with instead of across the device 3.
