Abstract: 620,328. Gravity-feed lubricators. FAIRFIELD SHIPBUILDING & ENGINEERING CO., Ltd., and DAVIS, A. W. Dec. 20, 1946, No. 37470. [Class 12 (iii)] [Also in Group XXIV] The turbine and gearing bearings 16 and hydraulic couplings 6, 7 of a marine reversing and reduction gearing of the kind described in Specification 619,866, [Group XXIV], are fed by a gravity tank 22 supplied from a lubricating pump 19 which is driven, directly or through toothed or chain gearing 20, from the astern driving pinion 2 and serves during propulsion by the ahead driving pinion 1 to supply a restraining torque to the pinion 2 to maintain its teeth in continuous engagement with the driving surfaces of the teeth of the driven gear 3. The pump 19 may operate during ahead and astern propulsion or during ahead propulsion only. Oil drains from the bearings 16 and couplings 6, 7 to a low-level tank 24. A booster pump 26 actuated by an electric motor 27 controlled by a float switch 29 is in parallel with the pump 19 and is switched on and off when the oil level in the tank 24 rises and falls beyond predetermined limits. According to the Provisional Specification, the booster pump may be controlled by the oil level in the gravity tank, and more than one pump may be driven from the astern driving pinion.

Title: Improvements in or relating to yarn packages
Inventor: VOGEL HANUS PETER
IPC: B65H55/02
Filed: 1959-11-09
Abstract: A coreless cop for a loom shuttle comprises yarn of continuous filaments of synthetic polymeric material, e.g. a polyamide or polyester, which has been treated, prior to winding, by coating the yarn with a non-adhesive thermosetting or thermoplastic compound dissolved or dispersed in a volatile liquid vehicle and then drying the yarn to remove the liquid vehicle so as to cause the yarn to be self-adherent but non-tacky.  The coating compound may comprise a nylon polymer, polyvinyl acetate or an acrylic emulsion.  In one example, a polyethylene terephthalate filament is twisted and passed through a nylon polymer solution, containing methyl stearate for lubrication, passed over synthetic foam to remove excess moisture and treated in steam.  Packages are wound from this yarn after passing it again through a bath of similar solution.  The wound packages are exposed in moulds to a temperature of 110 DEG C. and are then cooled suddenly.  In another example, nylon yarn is coated with an acrylic emulsion.

Title: Apparatus for maintaining the speed of a road vehicle substantially constant

Abstract: 983,985. Automatic speed control. JOSEPH LUCAS (INDUSTRIES) Ltd. Sept. 28, 1961 [Nov. 9, 1960],No. 38444/60. Heading G3R. The speed of a road vehicle is maintained at a predetermined value by obtaining an electrical signal whose value depends upon the difference between the actual and desired speeds, means responsive to said signal controlling a throttle valve in the air intake manifold of the engine. The desired speed is selected by adjustment of potentiometer 12, closure of switch 39 energizing selfholding relay 36 provided that the vehicle is in top gear and none of the control pedals is depressed. Thus,direct voltage is applied across terminals 1, 2, so that capacitors 7, 17, and diodes 8, 9, form a diode pump circuit operable by signals applied to terminal 4 from the ignition system of the vehicle, and producing an output substantially proportional to the speed of the vehicle in the form of a saw-tooth voltage superimposedupon a direct voltage. -The voltage produced across resistors 10,13,by potentiometer 12 is subtracted from this voltage and the resultant signal is fed to transistor amplifier 15,19,22. The average current in coil 25 thus depends uponthe difference between the actual and desired speeds,  and throttle valve 29 is adjusted to tend to reduce the difference to zero. Energization of coil 25 tends to close valve 26 in pipe-line 27 extending from atmosphere to a position in air intake manifold 28 downstream of throttle valve 29. Evacuated bellows 32 is secured to the valve 29 and the arrangement is such that closure of valve 26 opens the valve 29.

A vending machine comprises a row of article dispensing units, each comprising a plurality of shelves on an endless belt conveyer, and each being readily displaceable. Fig. 5 shows one unit, the casing of which is suspended by hooks 120 from a telescopic runner in the roof of a cabinet, and is closed on one side face only, so that each unit may be drawn forwards, reloaded from the open side, and then replaced. The endless conveyer comprises articulated sections running over sprocket-wheels, and supports shelves 100, each of which in turn deposits its article on to a plate 102 behind an inspection window 70. The closed side of the unit is double walled, and contains mechanism which on displacement of lever 264 accessible through slot 112, deflects plate 102 to dispense an article, and advances the conveyer one step. Mounted within the cabinet and beneath each unit is a frame 230, Fig. 11, mounted on a common shaft 220 and having a normally retracted finger 248. Insertion of coinage at a common station is noted by a stepper mechanism, and pressing of a button corresponding to a selected dispensing unit will, if correct coinage has been inserted, release a catch 244 electromagnetically so that the corresponding finger 248 is released, and extended by spring 250.

The selected article is thus dispensed, and replaced by another. A further common shaft has cams 168 locking the units in retracted position, rotation of this shaft being interlocked with closure of a front door of the cabinet.

Title: Electromagnetic wave transmission device
IPC: H03C7/02
Filed: 1958-12-11
Abstract: 851,519. Waveguide ferrite devices. HUGHES AIRCRAFT CO. Dec. 11, 1958 [Jan. 3, 1958], No. 40049/58. Class 40(8). [Also in Group XL(c)] An electromagnetic wave transmission device, suitable for use as a microwave modulator or switch, comprising a ferrite element located inside a waveguide and inside a solenoid, is characterized in that said device has a body of dielectric material in which a bore is coated with a metallic film providing said waveguide, and that said solenoid is disposed inside said waveguide. The device shown comprises a dielectric cylinder 10, e.g. of nylon, having a bore 12 on which a conductive film e.g. of silver, nickel, copper or gold is deposited by vaporization, precipitation or chemical reduction plating to form a waveguide 16. The thickness of the film is made approximately four times the skin depth of the metal at the fundamental frequency of the microwaves to be modulated so the device has a low insertion loss. A ferrite element 18, having at each end a tapered portion surrounded by a dielectric plug 34, is supported in an axial bore of a coil former 20 of dielectric material having a reduced diameter section 22 containing a solenoid 26 connected by leads 28 and 30 to a modulating signal source 32. The coil former 20 is surrounded by a dielectric sleeve 24. Resistive cards 44 and 46 are located between four semi-cylindrical supports 48 of dielectric material similar to that of the coil former 20 and the sleeve 24. Metallic plates 36 and 38 fastened to the ends of the cylinder 10 have rectangular openings 40 and 42 with their longer dimension parallel to the cards 44 and 46. Auxiliary solenoids 52 may be accommodated in reduced diameter sections 50 in the surface of the cylinder 10. In operation, HO1 mode waves from a source 54 excite H11 waves in the waveguide 16. If the E vector is perpendicular to the card 44 no energy is absorbed. After rotation by the ferrite element 18 components parallel to the card 46 are absorbed and components perpendicular thereto are transmitted to a utilization device 56 in the form of an amplitude modulated signal. Placing the solenoid 26 inside the waveguide 16 reduces eddy current losses and provides a low reluctance magnetic circuit, thus enabling the source 32 to be of low power and to operate at modulating frequencies of many mcs./sec.
