Title: An Improved Process and Equipment For Converting Barley Into Malt
Inventor: POLLOCK JAMES RICHARD ALLAN
IPC: A23N/
Filed: 1965-09-08
Abstract: 1,154,502. Mixing apparatus. MALTING DEVELOPMENTS Ltd. 30 Aug., 1966 [8 Sept., 1965], No. 38348/65. Heading B1C [Also in Division C6] Partially malted grain in a malting vessel M is progressively loosened for immediate discharge through an outlet 3 by a sweeper arm 33, Fig. 1, which carries a plurality of radially extending helically arranged tines 35 and is connected for rotation to an electric motor 30 through a universal coupling 32, whereby the sweeper arm performs gyrational movements 42 about its mounting as the malted grain in the vessel discharges. A rotating worm carrying tines may be employed instead of the sweeping arm. The partially malted grain thereby loosened is immediately discharged to a separate vessel, the entangled rootlets becoming disentangled by the loosening and discharging prior to continued processing. The malting vessel has a conical perforated partition 2a in which are located air injection nozzles 41b supplied with air from a compressor 41a for agitating the grain. Conditioned air from a conditioning unit 19 is passed into the malting vessel through line 17 or 20. Water is supplied from a reservoir 10 or conduit 26. The temperature at various levels in the malting vessel is determined by a series of thermometers 43. The grain may be steeped in the making vessel at ordinary or elevated (40‹C) temperatures. According to the embodiments: (i) partially malted grain is discharged and transferred from a malting vessel (M 1 , (Fig. 2, not shown) into a storage vessel (S 1 ) by a system of conveyors (37, 38, 36) and is then re-transferred to the empty malting vessel; (ii) partially malted grain in malting vessel (M 2 ) (Fig. 3, not shown) is transferred into storage vessel (S 2 ), partially malted grain is transferred from malting vessel (M 3 ) into vessel (M 2 ), and then the partially malted grain in storage vessel (S 2 ) is transferred into malting vessel (M 3 ); (iii) a similar procedure is applied in a system of four malting vessels and one storage vessel (Fig. 4, not shown); and (iv) partially malted grain is progressively transferred from one malting vessel to the next in series (M 8  to M 11 ) (Fig. 5, not shown) and the storage vessel (S 4 ) is employed only for the transference involved in circulating grain from and to the same malting vessel. Depths of grain of the order of 13 feet can be handled. The grain may be sprayed with water during its transference. The malted grain is kilned.

Abstract: 1329883 Digital transmission; fault testing SIEMENS AG 24 Aug 1971 [23 Sept 1970] 39729/71 Heading H4P In a synchronous data transmission system in which a scrambler (SC) is provided at the transmitting end and a descrambler (DSC) at the receiver, the system may be tested by providing a continuous input via a switch (S1) to the scrambler so that it develops a quasirandom sequence which is checked at the receiver reforming the continuous signal which is applied to a fault indicating device (SA). Terminal (M) provides a test signal = 1. The signal emitted by the descrambler is conducted to terminal S. In the event of any 0's occurring the number of bits has been incorrectly received hence any faulty 0 bits are applied by an inverter G1 to one input of a gate G2 second input of which receives the pulse train through terminal T which switches gate T2 for a duration of a timing pulse during faulty bits. Gate G2 triggers a monostable circuit K1 causing lamp SL to illuminate via amplifier V1 for a determined period e.g. 300 ms. Monostable K1 recommences the timing period if retriggered in the operative state. Gate G2 also is connected by an amplifier V2 to a terminal Z connected to a counter or indicator to record or indicate a number of faults during the test period.

Abstract: 1368102 Rolling mills FRIED KRUPP HUTTENWERKE AG 27 Aug 1971 [28 Aug 1970] 40358/71 Heading B3M  The continuous or semi-continuous operation of a multistand rolling mill is controlled according to a desired physical property of the material being rolled, the gaps between the rolls and their speeds at each successive stand being regulated in dependence on the rolling force at the first stand and the reduction of workhardening effects which occur in the material as it passes between adjacent stands. Preferably the yield stress of the material before passing through the first stand is calculated from the rolling force at the first stand, and the yield stress before each succeeding stand is calculated taking into account the increasing value of yield stress as the material passes through each stand and its decreasing value between stands. The calculations may be performed by a computer, the equations for determining the values of yield stress at each stand being given in the Specification.

Abstract: 1313730 Endarteriectomy apparatus COOK INC 31 Aug 1971 [9 Nov 1970] 40549/71 Heading A5R [Also in Division F2] Apparatus 10 for removing arterioscelerotic material from a body vessel 105 comprises a rod 70 having an axis, proximal end and distal end, means 30 secured to the proximal end of said rod for oscillating said rod about its axis, and a looped tip 72 secured to the distal end of said rod.  Operation. Upon operation of motor 11, springs 16, 17 rotate and cause rotation of the shafts 36, 43 of the convertor 30. The rotary coupling 47 rotates with shaft 43 forcing the ball 50 to rotate within the slot 54 in the same direction as springs 16, 17. In addition, motion of the ball 50 will cause the centre coupling 52 to oscillate about fastener 51 in the direction of arrows 81. Elbow coupling 60 thus oscillates and imparts oscillatory motion to rod 70. An endarteriectomy is performed by first making an incision into the artery (Fig. 5 not shown) and introducing the rod 70 inside. The loop 72 is located between the medial layer (102) (Fig. 6 not shown) and adventitial layer (101) to position the arterioscelerotic material inside loop 72. The looped tip 72 is then oscillated by converter 30 and motor 11 and advanced slowly along the artery. The arteriscelerotic material is stretched away from the adventitial layer and the intact core (107) is then removed from the artery using a haemostatic clamping device (125). A debinding instrument (135) may be passed into the artery to remove any remaining arterioscelerotic material.
