Title: Method and apparatus for cooling milk
IPC: A23C3/04
Filed: 1952-12-10
Abstract: 724,061. Freezing milk. BROWN, BOVERI & CIE AKT.-GES. Dec. 10, 1952 [May 30, 1952; July 26, 1952 ; Oct. 16, 1952], No. 31277/52. Class 29. [Also in Group VI] Small pieces, e.g. cubes, of frozen milk are formed in partitioned trays 1 supported on plates 4 cooled by evaporators 5 or by eutectic brine and housed in a chamber 7, the trays being formed with means such as overflow spouts 3 to supply milk from one tray to succeeding ones. The level of the spout is between the partition tops and the top of the trays so that the ice pieces are joined together by a thin sheet of ice. Milk is supplied from a container 8 through a filter 9 and a restriction 10 to the first tray and a drain 10a for excess milk is provided. Alternatively, the container 8 holds only enough milk to fill the set of trays. The trays may be located in recesses in the plates which may be located so close together that the upper plate is near the surface of the milk in the tray beneath, removal of the trays being facilitated by making the plates vertically separable by a linkage. The plates or, possibly, the tray walls may have heating means such as electric heaters or pipes 6 for hot water or gaseous refrigerant to free the ice. In a modification, the trays may be arranged in side-byside groups of superposed trays, milk being supplied from an upper container to a selected group through a turn cock and the trays having overflow tubes serving also as handles.

Title: Improvements relating to apparatus for correcting unbalance in rotors
IPC: G01M1/34
Filed: 1958-10-02
Abstract: 897,064. Punching; welding by pressure; riveting; drilling. AVERY Ltd., W. & T. (Schenck Maschinenfabrik G.m.b.H., Carl). Oct. 2, 1958, No. 31435/58. Classes 83 (3) and 83 (4). A balancing machine for balancing rotors is provided with apparatus for correcting the unbalance of the rotor while the latter is on the work-holder of the machine without transmitting pressure to the work-holder. The frame la, Fig. 1, of the balancing machine, in which a rotor 6 is mounted on a work-holder 5, carries a sleeve 7 in which is slidingly supported the pillar 9 of a drilling-machine 8 which is counterbalanced by a spring 10 or weight 14. The floating mounting ensures that when the drill 11 is lowered by the handle 16 on to the rotor 6, the drilling pressure is taken up by engagement of a rest 15 secured to the pillar 9 with the underside of the rotor. The drill may be swung clear during balancing and is located in its operative position by adjustable stops 27, 28. In a modification, the correcting apparatus is a shearing, welding or riveting machine, floatingly mounted as described above. In the shearing machine a manually-actuated blade co-operates with an anvil fixed on the pillar 9. In the welding machine, an electrode fixed to the pillar 9 and a pneumaticallyactuated electrode co-operate to spot-weld a piece of lead to the rotor. In the riveting machine, two sets of riveting dies are provided actuated by separate handles and automatically supplied with rivets from magazines holding two sizes of rivets. In a further modification, Fig. 9, the correcting apparatus is a drilling machine having two drills 11a, 11b for drilling either side of a rotor 6a. The drills 11a, 11b and their motors 33. 34 are adjustably mounted radially of the rotor 6a in carriers 8a, 8b. A shaft 9a rotatably mounted in the carrier 8b and movable axially therewith, has a threaded portion engaging a nut 9d secured to the carrier 8a. Rotation of the shaft 9a by a motor 32 moves the carrier 8a vertically in a slideway on the carrier 8b to bring the drills 11a, 11b towards or away from each other. Where one drill 11a or 11b is to be used one of two rests 15a, 15b mounted respectively on the carriers 8a, 8b is extended by fluid pressure to engage the opposite side of the rotor 6a. The carriers 8a, 8b and their associated parts are counterbalanced by a weight 14.

Filed: 1932-11-08
Abstract: 410,096. Controlling variable - speed gearing. HAMILL, W. W., Beechcroft, Four Oaks Road, Four Oaks, Sutton Coldfield. Nov. 8, 1932, No. 31461. [Class 80 (ii).] Comprises in combination with an internalcombustion engine, a clutch 10, change-speed gear 12, and an isolating clutch 11 between the change-speed gear and the road wheels, engine-suction-operated power means 6 for operating the clutches, a controlling device 2 for the power means, and a speed-responsive device 1 which operates the controlling device so that the power means disengages both clutches when the engine or vehicle speed falls to a predetermined low limit and re-engages the clutches when the speed rises again above said limit. The speed-responsive device may be either of the fluid-pressure type or the centrifugal governor type shown, and may be driven from the engine alone, or through sprockets 19, 20 driven in accordance with engine and vehicle speed respectively, free-wheel clutches being provided in these sprockets so that the governor 1 is driven by whichever sprocket rotates at a higher speed. The governor 1 operates a piston valve 17 controlling a connection between the induction pipe 3 and the power cylinder 6, so that when the governor speed is low the valve 17 connects ports 4, 5 and the piston of the power cylinder is operated to pull a rod 7 and disengage both clutches. When the speed rises the connection to the induction pipe is cut off and the clutches are re-engaged. The isolating clutch 11 is of positive dog type, and preferably is disengaged after the main clutch 10, while it is re-engaged before 10 re-engages. This may be effected by providing the isolating clutch with long jaws to allow a sliding motion during the engagement of the main clutch.

Abstract: 771,596. Pulse generator circuits. METROPOLITAN - VICKERS ELECTRICAL CO., Ltd. Dec. 2, 1954 [Nov. 13; 1953], No. 31553/53. Class 40(6) A circuit for triggering an electric discharge device which is fed with A.C. volttage from the secondary winding of a transformer comprises a pulse generating blocking-oscillator circuit which is fed from the transformer and which triggers the device at a pre-determined instant in each A.C. cycle. The figure shows a portion of a pulse modulator in which a storage circuit C3 is charged resonantly from the A.C. supply and is discharged through a load by firing a trigatron V2. The A.C. voltage across the lower overwound section of transformer T1 is rectified by rectifiers D1, D2 the former. of which supplies the H.T. voltage and the latter the bias voltage to a blocking oscillator, circuit comprising tube V1. The rapid change in current flow through inductor L1 due to the blocking oscillator effect causes a sharp positive pulse to be generated at the anode of tube V1 which triggers tube V2. Adjustment of resistor RV1 enables the point in the A.C. cycle to be adjusted at which tube V1 blocks and hence tube V2 fires this always occurring however due to the winding of transformer T1 when the anode of tube V2 is at a voltage negative with respect to its cathode.

Title: Method and apparatus for the forming of equivalent portions of bast fibre stalks, especially flax, in order to make possible the continuous working up of these stalks into a bast fibre sliver suitable for further treatments
Inventor: BOK CORNELIS
IPC: D01B9/00
Filed: 1959-09-18
Abstract: 900,630. Rotary conveyers. NOVIVLAS N. V. Sept. 18, 1959, No. 31892/59. Class 78(1). [Also in Group IX] Apparatus for feeding and separating bast fibre stalks at an intermediate stage of obtaining and preparing the fibres for spinning (see Group IX) comprises a regulatable, continuously - operating feed mechanism, stowing apparatus which regularly collects a variable quantity of stalks and compresses them at one predetermined distance from their root ends so that they are stowed closely together without crushing, and mechanism which completely separates bundles of constant crosssection from the stowed quantity and transmits them separately to the next conveying apparatus. As shown, a prepared layer 1 of flux stalks is continuously conveyed between bands 2 and between fixed and adjustable leads 3 and 4. The stalks are then transported periodically by pulsating action of a member 5 which stows each quantity within framework 28 and against a movable lock 6 formed by the back of a tooth 7 on the rim 8 of a dosing wheel 9. Each time the compression of the stalks reaches a maximum, wheel 9 turns by one tooth so that the top 29 penetrates the compressed mass of stalks and separates therefrom a bundle of precise cross-sectional area. On further movements of the wheel 9, the bundle clamped between parts 31, 32, of the tooth flanks moves to a position 33 and as it approaches a discharge station it is retained between leads 58 and 4 by a spring-constrained, rotatable finger 59 until removed by a grab 61 of a conveying apparatus. A separator 50 prevents entanglement and overlap of stalks of successive bundles in the positions 33. The rim of wheel 9 is connected to a carrier disc 45 which supports the stalks and enables a saw 62 to remove the root ends. The driving mechanism of the stowing apparatus synchronously effects the step-by-step advance of wheel 9 so that stowing occurs during the time that the wheel is in motion. In the operation of the stowing apparatus, the member 5 is guided by a pivoted arm 10 and actuated by a sliding, spring-controlled stowing arm 14 alternately to forward and compress stalks and then to glide over incoming stalk material. Arm 14 is moved by an eccentric shoe 15 (engaging a stop 18) connected to an eccentric disc 20 the shaft of which is driven indirectly and through chain-transmission from the machine drive 54 and carries adjustable control cams 21, 22 serving limit switches 23, 24; a cam disc 25 secured to an extension of the shaft of disc 20 mounts a cam 26 serving a control switch 27 which provides over-riding control of switches 23, 24. A servo-mechanism ensures that, when a desired adjustable reach of the arm 14 is either exceeded or not attained, the speed of the mechanism supplying the stalks is appropriately adjusted, Fig. 7 (not shown).
