IPC: C12C7/26
Filed: 1922-08-29
Abstract: 207,605. Wooldridge, H. B., and Soc. Anglo-Belge du ProcÚdÚ Wooldridge. Aug. 29, 1922. Wort, hopping; wort, special treatment of.- Wort, after boiling with hops in a closed vessel, is cooled by evaporation under traduced pressure and drawn by suction without the use of the pressure of the external air, into a fermenting vessel. The boiling vessel a is provided with a heating coil b and a cooling coil c, and in it the wort is boiled and the vapour allowed to escape. The vessel is then closed and air withdrawn by a pump until a vacuum of about 5 inches of mercury is produced'. The wort is then drawn through the spent hops resting on a strainer l through a pipe into the fermenting vessel k in with a vacuum of about 30 inches of mercury has been produced. In the vessel k is a coil of pipe o, the top and bottom turns of which are perforated and can cut off from the rest of the coil. The pipe is so connected to one end of the coil o that the wort traverses the whole coil and enters the vessel k by the perforated turn at the other end. If the wort is not sufficiently cooled by co-operation it can be cooled further by circulating cold water &c. through the coil o. Purified air may be introduced to cool, aerate and agitate the wort. Specification 16744/10 is referred' to.

Title: Improvements relating to photographic camera shutter mechanisms
IPC: G03B7/083
Filed: 1964-06-05
Abstract: 1,060,248. Photo-electric exposure control. INTERNATIONAL POLAROID CORPORATION. June 5, 1964 [June 17, 1963], No. 23439/64. Heading G1A. An automatic exposure control system for a photographic camera is compensated for variations of its own sensitivity or of film speed with temperatare. The shutter control system of Specification 1, 047, 866 is modified by the connection of a thermistor T 1  to the base of transistor Q 2 . The thermistor is so chosen that changes in the gain of Q 2  with temperature are balanced by changes in the base bias so that the current in Q 2  is substantially independent of temperature. Consequently the current in solenoid 38 is constant and the base voltage at which Q 1  begins to conduct (the trigger voltage) is constant. If the film in use requires greater exposure at low temperature, T 1  is made to overcompensate the gain of Q 2  and Increase the trigger potential at low temperature. The same Increase in exposure may be achieved by supplying the timing circuit 44 from a voltage divider T 2 , 58 with a voltage which decreases with decrease in temperature. If the circuit is provided with a resistor between 49 and transistor Q 2  to compensate for non linearity of the photoconductor 45, as disclosed in Specification 1,052,125, the resistor is made temperature sensitive by the provision of thermistor T 3 .

Title: Driving mechanism for a machine for manufacturing wire fabric
IPC: B21F27/04
Filed: 1952-09-19
Abstract: 741,997. Operating clutches. WAKEFIELD, J. A. Dec. 21, 1953 [Sept. 19, 1952], No. 23528/52. Class 80(2) [Also in Group XXII] A machine for making chain link fabric including a multiple-revolution coiling shaft and an alternately driven singlerevolution shaft for operating wire severing and cut-end knuckling means has driving mechanism for the shafts which includes a continuously-driven main spindle driving the multiple-revolution shaft through an epicyclic gear and the single-revolution shaft through a clutch, and automatically-operating clutch control mechanism to cause the single-revolution shaft to remain stationary while the multiple-revolution shaft turns and viceversa, drive from the epicyclic gear being cancelled out when the single-revolution shaft turns. A continuously-driven spindle 1 alternately rotates a shaft 3 for one revolution, through worm 7, gear 9 and clutch 10, and a shaft 2 for several revolutions, through worm 6, gear 8 and epicyclic gear 26. The clutch comprises a drum 10, Figs. 9, 10, secured to the driving gear 9 and free on the shaft 3, a coupling member 12 inside the drum 10 and fast on the shaft 3 and formed with peripheral flats 14, and a cage 18, free on the shaft 3, extending between the drum 10 and coupling member 12 and loosely carrying, in slots 22, rollers 23. A peg 16 on the member 12 engages a slot 24 in the cage 18 of such a length as to allow relative rotation of the member 12 and cage 18 either to jam the rollers 23 between the member 12 and drum 10 and thus engage the clutch or to release them and thus disengage the clutch. The epicyclic gear includes an annulus 26 secured to the driving gear 8 and free on the shaft 2, a sun 28 fast on the shaft 2, and a planet carrier 27 loosely sleeved on the shaft 2 and rotatably connected to the shaft 3 through sprockets 29, 25 and chain 30. In operation, assuming the clutch 10 disengaged and the shaft 3 consequently still, the shaft 2 is rotated through the epicyclic gear until a tooth 48 on a disc 39, rotated from the shaft 2, engages a tooth 47 on a link 45 to rock a lever 40, against a spring 44, to disengage a catch 42 from a notch 43 on the cage 18 of the clutch. The clutch immediately engages to rotate the shaft 3 ,which rotates, through the chain 30, the pinion carrier 27 to cancel out the drive from the annulus 26 and thus to stop the shaft 2. During the rotation of the shaft 3 a hump 51 on the pinion carrier 27 lifts the lever 45 off the tooth 48 to allow the catch 42 to move back into a position to engage the notch 43 and disengage the clutch 10 when the shaft 3 has rotated once.

Title: Heat treatment of strip material
Inventor: INGALL JAMES BIRKETT
IPC: C21D9/58
Filed: 1962-06-20
Abstract: <PICT:1039653/C6-C7/1> A method for continuously heat treating elongate metal material, such as continuous annealing of steel strip at 700 DEG C. or more, comprises passing the material longitudinally through a bath of fluid heat transfer medium, heating the fluid to heat the material in turn by conduction in an intermediate portion of the material's path through the bath, and circulating the fluid in the remaining portions of the bath to transfer heat from the outgoing material to the ingoing material, e.g. to preheat it to 200 DEG C. The fluid medium may be fluidized but is preferably a liquid and electrically conductive, e.g. molten lead alloy such as Pb-Bi entectic.  As shown, a strip 14 is passed through a V-shaped chamber 11 provided with a guiding roller 13 at its bight 12. The limbs of the chamber are joined by transverse passageways 16 and 15, the latter containing a pump 17 for circulating a fluid heat transfer medium contained in the chamber counter-current to the strip movement, so as to form a closed liquid circuit ADCB in which the heated strip leaving the bight 12 is quenched in limb portion D and the ingoing strip is preheated in limb portion B. The bight 12 and adjacent limb portions with passageway 16 form a closed loop CEGF, which is embraced by a laminated core 18 of a transformer winding 19 connected to A.C. supply 20, and thus acts as a secondary winding circuit.  A straight duct for passage of strip may be employed instead of a V-shaped chamber (see Figs. 2 a-b, not shown), the intermediate portion of which communicates with three W-shaped fluid channels depending therefrom, each with a heating transformer core located around its central arm, and the transformer arrangements are associated in a balanced 3-phase electrical circuit.

Title: Improvements in and relating to fatigue testing machines
Inventor: COX HAROLD LESLIE
IPC: G01N3/34
Filed: 1949-09-16
Abstract: 679,484. Fatigue testing of materials. NATIONAL RESEARCH DEVELOPMENT CORPORATION. Sept. 14, 1950 [Sept. 16, 1949], No. 23940/49. Class 106 (ii). A fatigue testing machine for applying alternating or pulsating loads to a test piece 22 comprises means for oscillating a mass 6 between opposed compression springs 7 preloaded to such an extent that the springs 7 remain under compression even at the maximum amplitude of motion of the mass, the springs 7 extending between cross-heads 2, 3 rigidly coupled together by bolts 4 and forming a unit for applying the load to the test piece 22, the means for oscillating the said mass including a slipping clutch 16 so that, when starting up, a resonant frequency of oscillation may be created in the system without overloading the driving unit or the test piece in the process. The springs 7 are threaded over the tie bolts 4. Movement of the mass 6 loads the upper and lower crossheads 2, 3 alternately by increasing the load on two of the springs 7 and decreasing it on the other two, The mass 6 is vibrated by a connecting rod 14 connected to a variable throw crank 13 driven by an electric motor. When the motor is started, the connecting rod 14 slips in a clutch, Fig. 2, coupled to the mass 6 until the exciting frequency approaches the resonant frequency of the mass and spring system, when the friction of the clutch is sufficient to maintain the mass in vibration at an amplitude determined by the throw of the crank 13. The clutch is attached to the mass 6, Fig. 2, by plate springs 15 embodying two blocks 16 between which the rod 14 is held by adjustable pressure means 17, 18, 19. Fluctuating loads can be applied such that the mean load is zero, compressive or tensile. The mean load is created by causing static springs 8 to load either the upper or the lower cross-head through the medium of nuts 11 for raising or lowering the rods 10 and their collars 9, Fig. 1. The rod 14 may be a tube and its dimensions are such that its natural frequency as a cantilever beam fixed at the lower bearing 20 is the same as the exciting frequency. The stresses exerted on the test piece 22 are measured by noting the deflections of the springs 7 and 8.
