Abstract: 701,833. Measuring heat quantities. LANSNER, A. E. Oct. 17, 1951 [Oct. 18, 1950], No. 24216/51. Class 97(3) In an apparatus for measuring the quantity of heat contained in a medium flowing through a pipe 10 comprising a vaporizer 20 containing a liquid 18 which is heated by the fraction of the medium which flows through the branch pipes 12, 16, and coil 14, a condenser 30 which is kept cooled down to a reference temperature, and a device 34 for measuring the amount of condensate circulating within the closed system, the cooling agent 32 of the condenser 30 consists of a substance which is partly liquid and partly solid during the operation of the apparatus. Calcium chloride hexahydrate having a melting point of about 29‹C is packed into the tank 30 around the condensing coil 28 and copper shavings or other heat conducting material may be mixed therewith. The tank 30 is so insulated from the surroundings that the heat which is supplied to the cooling agent 32 is eventually lost to the surroundings. The condensing coil 28, which may be subdivided into a number of parallel tubes, extends upwardly from a pre-chamber 24 which 'receives the vapour from liquid 18 and has a pipe 26 discharging the condensate into a measuring wheel 34 whose revolutions are registered. The condensate returns to the vaporizer 20 through pipe 38. Specification 701,832 is referred to.

Title: Method for carrying out continuous fermentation
IPC: C12C11/09
Filed: 1974-06-04
Abstract: 1422076 Beer; yeast ALFA-LAVAL AB 4 June 1974 [9 July 1973] 24762/74 Headings C6E and C6F A method of carrying out continuous fermentation of a substrate by micro-organism cells involves continuously supplying the substrate to a flow circuit including an elongated, closed channel, mixing the substrate with a mass of living cells in the circuit for continuously fermenting the substrate, passing the mixture as a coherent plug through the channel, and, after fermentation has taken place in the circuit, centrifugally separating the mixture into fermented substrate, living cell mass and impurities, and discharging from the circuit the fermented substrate, impurities and excess living cell mass formed during the fermentation. Referring to the drawing, fresh wort from line 1 and recycled living cell mass from line 4 are mixed in mixer 3, the resulting cell-containing substrate is passed sequentially through heat exchanger 5, fermenter 7, heat exchanger 10 and fermenter 18, and the attenuated fermentation liquid is cycled through line 15 to a centrifuge 16 from which fermented wort (beer) is taken off through paring tube 22 and line 23, living cell mass together with entrained air is discharged through paring tube 28 and is mostly led back to the fermentation through line 4, and the sludge 31 of impurities is removed through openings or nozzles (not shown). The amount of entrained air in the living cell mass can be adjusted by regulation of throttle valve 30. When producing beer, a part of the carbon dioxide collected from the fermenters in line 11 is pumped under pressure to be mixed with the beer discharged through line 23. Water for heating/cooling is supplied to the heat exchangers through line 20 and withdrawn through line 21. Examples 1 and 2 relate to the production of beer and yeast, respectively.

Patent GB-404902-A (GB)
Title: A sheet feeding machine
IPC: B65H3/00
Filed: 1933-09-08
Abstract: 404,902. Feeding sheets. MILLS, C. K., 34, High Holborn, London.-(Cross Paper Feeder Co. ; 185, Sumner Street, Boston, U.S.A.) Sept. 8, 1933, No. 24897. [Class 100 (i).] To increase the speed of continuous sheetfeeding machines of the kind, such as those described in Specification 25663/02, [Class 100, Printing, Letterpress &c.], in which a pair of combing rollers 10 effect a preliminary separation of sheets from a feathered bank S which is advanced over a feed-table 1, the combing rollers 10 are arranged an appreciable distance from the front end of the table 1 beneath which trip fingers 49 are provided for controlling the raising of the rollers 10 out of action, and the sheets are fed off by suction devices 60 which advance them to drop rollers 62 arranged above the table 1. The trip fingers 49 are permitted to return to their normal position while the sheets are being fed off, and the combing rollers are arranged to come into action as soon as the rear end of the sheet which is being fed passes the rollers 10. Each roller 10 is mounted in a pivoted arm 12 which is connected by a link 14 with a shaft 15 journalled in the ends of two levers 16, fixed on a shaft 17 fitted with a lever arm 18 connected to a link 20 which is operated by a roller 56 and cam 55 to raise the entire combing-mechanism out of action after the combing roller 10 has been released by the trip finger 49. A presser foot 21 is operated by toggle mechanism 23, 24 to engage the pile when the combing roll is raised. The roller 10 is maintained in the active position, Fig. 1, by a spring-controlled pivoted latch 37 which engages a tappet 36 on a lever 33 connected by a link 31 to a bell-crank 27 mounted in the lever 16 and acted on by a spring 28 which tends to straighten out toggle levers 24, 23 and so depress a presser foot 21 on to the pile and raise the combing roller 10. This action takes place when the sheet actuates the trip finger 49 and so releases the latch 37. The latch 37 is on a lever 38 pivoted to a freely mounted lever 40, and its release from tappet 36 is assisted by a rotating ratchet 52 into engagement with which the end of the finger 49 is brought when released by the sheet. The trip mechanism is reset by a cam 42 which, after the sheet is raised by the nozzles 60, permits the latch 37 to engage the tappet 36 and then raises the right-arm of lever 33 and depresses the left arm to restore the roller 10 to the position shown in Fig. 1. The separated sheet is registered against an oscillating stop 64 with bent upper parts 63 which overlap the front edge of the sheet and ensure engagement of the sheet with the finger 49.

Abstract: 302,716. Automatic Telephone Manufacturing Co., Ltd., and Passmore, W. O. Sept. 21, 1927. Addition to 221,175. Semi - automatic exchange systems. - In a system of the kind described in the parent Specification in which calls are set up by operators by means of keyboard-controlled impulse senders accessible in common to a number of operators over selecting switches, a faulty setting of the keyboard may be cancelled by operation of a key 175, which, through relay 157, removes momentarily the holding and guarding potential from wire 135 to restore the impulse sender to normal, and the present invention provides means for preventing seizure of the impulse sender by another selecting switch while this operation takes place. The application to the system described in Specification 229,765 is described. When an impulse sender is seized, two-step relay 11 energizes partially over wire 135 in parallel with relay 253, and attracts armature 13. On operation of the key 175, ground is removed from wire 135, and relay 11 energizes fully, applying a fresh ground to wire 135, disconnecting wire 19 to restore the operated relays, and connecting up a sluggish relay 17. The latter upon pulling up energizes cut-off relay 246 (relay 253 now being de-energized) to restore the circuits to their original condition.

Abstract: 319,353. Swynghedauw, P. E. G. Sept. 21, 1928, [Convention date]. Void [Published under Sect. 91 of the Acts]. Breaking and scutching apparatus. - In a machine for breaking and scutching flax, hemp, ramie, &c., the material held between travelling chains 28, 31, Fig. 1, is carried along a. slot 2<1> between the halves of a curved; table 2 carrying on the under surfaces blades 3. A roller 7 with blades 8 is mounted on arms 5 centred on a shaft 4 below the slots 2<1> and is rocked to cause the roller to move over the surface of the table 2, the blades 3, 8 intermeshing. The material hanging through the slot 2<1> is engaged on one side by the roller and broken by the blades 3, 8. The roller passes far enough to free the material and allow it to fall back into a vertical position. The roller then returns and engages the other side of the material breaking it, in its motion over the other side of the table. The arms 5 carry blades 20, and coacting blades 20<1> are mounted on arms 16 centred on the shaft 4. The material is engaged by these blades and bent as they are moved along its length. The arms 5 carry stops 19 which engage the arms 16 and push them over in front of the roller 7. The arms 16 are provided with counterweights 17 to return them into position. Combs 21 are adjustably mounted on the arms 16 to dress the ends of the material. The arms 5 are operated by a crank 10 driven from a shaft 26 which also operates through chain gearing the feeding chains 28, 31. Wires or blades 22 carried by arms 23 rocked by cams 25 on the shaft 26 are moved at the end of each movement of the roller 7 to free the material from the table 2. The. material may be passed through one machine and then transferred to the grip of another pair of chains to enable the other end to be treated. The second pair of chains are arranged at the opposite side of the second slot 2<1>, which is in line with the first. A rotary disc bends the material down between the two sets of chains as they are running side by side to position the material before it is finally gripped by the second pair of chains.
