Title: Apparatus for determining the state of operation of a production  machine
IPC: G07C3/00
Filed: 1972-09-01
Abstract: 1403043 Counting apparatus VDO ADOLF SCHINDLING AG 1 Sept 1972 [4 Sept 1971] 40732/72 Heading G4D  Apparatus for determining the rate of operation of a production machine has a unit pulse counter for counting the units produced, this counter resetting a clock-driven further counter after receiving a predetermined number of unit pulses, outputs of the further counter being connected viarespective switching elements to an AND-gate stage to recognize a particular count predetermined by the positions of the switching elements. The count of the unit counter is decoded and displayed. The unit counter is decimal and the carry output of the units order thereof also resets to zero the clock-driven further counter, partially enables a first AND gate and resets two bi-stables. The two bis-tables are set by respective further AND gates each input of each of which is connected by a respective changeover switch to a respective output of the further counter or to a "1" bit line. The further AND gates set the two bi-stables respectively on attainment of respective counts (selected by the switches) in the further counter. The set and reset ouputs of the two bi-stables respectively, form the remaining two inputs of the said "first" AND gate which thus provides an output (via another bi-stable) if the count of the further counter produced between successive carries from the units order of the unit counter, falls within the limits defined by the switches.

Title: Improvements in or relating to the manufacture of polyvinylidene chloride copolymer emulsions
Inventor: WOODFORD DAVID MALCOLM
IPC: C08F214/08
Filed: 1962-10-30
Abstract: A method for the production of aqueous vinylidene polymer emulsions comprises feeding separate flows of a vinylidene chloride monomer component and a comonomer component into a reactor containing water, there being present during copolymerization a catalyst and a surfactant, wherein the quantity of the vinylidene chloride monomer component required for the copolumerization is introduced into the reactor at such a rate that the addition of the total vinylidene chloride monomer component required is completed before the addition of the total comonomer component is completed, the comonomer component being added continuously during the copolymerization reaction. Specified comonomers are acrylates and methacrylates and mixtures, e.g. of ethyl acrylate and methyl methacrylate, acrylonitrile, mixtures of acrylonitrile with acrylates and/or methacrylates, styrene, vinyl chloride, vinyl acetate, acrylamide and vinyl crotonate.  The surfactant is preferably a mixture of nonionic and anionic materials, e.g. nonylphenolethylene oxide condensates and sodium lauryl sulphate.  The catalyst may be an ammonium persulphate-sodium bisulphite redox system, the components of which may be added incrementally. The comonomer may be introduced into the reactor through two separate flows, a major proportion being introduced through one flow concurrently with the vinylidene chloride, and the residual comonomer introduced subsequently through the second of said separate flows. In Examples (3) 5% by weight and (4) 7% by weight of mixtures of ethyl acrylate and methyl methacrylate, and (5) 5% by weight of acrylonitrile are withheld until the vinylidene chloride addition is completed. The emulsions may be used for coating.

Title: Improvements in or relating to ice-making apparatus
Inventor: TIPPMANN JOSEPH ROBERT
IPC: F25C5/08
Filed: 1962-10-31
Abstract: 999,366. Ice-making. CHICAGO STOCK YARD TURBO REFRIGERATING CO. Oct. 31, 1962, No. 41205/62. Heading F4H. In an ice-making machine a metal plate 14 has a freezing surface 16 and means for applying water on to the upper edge of said plate for flow downwards across surface 16, refrigeration means in heat exchange with the opposite surface 34 for refrigeration of the plate and a collecting trough 40 positioned below the plate and offset towards surface 34 to ensure that ice falling from surface 16 falls downwards clear of the trough. As shown, water is pumped from tank 44 via outlet 60 into distributer pan 22 where it flows through holes 26 on to distributer plates 20 and hence down the outside freezing surfaces 16 of freezing plates 14. The water and slush as it forms flows from surfaces 16 down the outside of drain plates 38 to fall into trough 40 which is inclined slightly. Water and any slush that flows from the open end 42 of the trough flows into auxiliary tank 46. The water then flows through holes 54 in the tank 46 into tank 44 to repeat the cycle, whilst any slush floats on the surface of tank 46. When a sufficient thickness of ice has formed on surfaces 16, the pump 63 and refrigerant flowing through pipes or passages 18 is turned off and warm water, e.g. at 50-75‹ F. is supplied to the inner surfaces 34 of the freezing plates 14 by distributer pipe 28 which is formed with axially aligned holes 30. The warm water is cooled by its path over surfaces 34 and is used in the next cooling cycle and is collected in tank 44. The warm water continues to flow until the ice sheet falls from the surfaces 16. By this time, however, the temperature of the water when it reaches tank 46 is almost as high as it was in pipe 28. To avoid it heating up the cold water in tank 44, the capacities of tanks 44 and 46 are designed so that the later relatively warmer water flows down overflow pipe 50. A baffle 62 (Fig. 4, not shown), is placed over outlet 60 to prevent any slush which may enter tank 44 from being circulated to the distributer.

Title: Improvements in change speed devices
IPC: F16H47/06
Filed: 1958-12-22
Abstract: 860,315. Hydraulic transmission of power. VOITH G.m.b.H., J. M. Dec. 22, 1958 [Dec. 21, 1957], No. 41354/58. Class 69 (2). An automatic change-speed device for a multi-speed drive having at least one turboconverter has its change-over points influenced by a primary member 16, 17 actuated by the output of the prime mover and an unstable centrifugal change-over device 1, 2, 3 which is connected to the output shaft of the drive and has an inherent hysteresis greater than the hysteresis for the change-over of the drive, the hysteresis of the centrifugal device being determined by the ratio of the arms of a lever 5 operatively connected between a spindle 3 effecting the change-over and a spring 4 acting in opposition to the centrifugal force. The centrifugal change-over device comprises weights 1 which co-operate with a plate 2 on the spindle 3 to rock the lever 5 against the spring 4 which is associated with a first changeover point of the drive and bears against a plate 6 on a shaft 7. The plate 6 is adjustable relative to a further plate 8 which is adjustably mounted on the shaft 7 and against which abuts a second spring 9 associated with a second change-over point of the drive and having its other end engaging a lever 10 which, in the normal position of the device engages a stop 11, the opposite end of the lever being spaced a distance 13 from the lever 5. The shaft 7 is axially located in the piston 16 of the primary influencing member which is movable against springs 17 by fluid pressure supplied from the filling pump of the converter when the drive does not include a turbo-coupling in addition to the converter, or, when a coupling is included, by compressed air supplied at a pressure determined by the driving engine and supplied through a throttle 18 and/or non-return valve 19. The piston 16 is thus moved according to the engine speed to axially move the shaft 7 and vary the tension in the springs 4, 9 so that the gear changes may be effected at different loadings of the converter. In operation, as the output speed rises, the increase in centrifugal force acting on the weights 1 first overcomes the stress in the spring 4 to effect the first change-over of the gears. Further increase in output speed then increases the centrifugal force acting on the weights to operate the second changeover of the gear against the stress in the second spring 9, the stress in the springs being determined by the driving engine. The reverse process occurs when the output speed decreases, the hysteresis at the change-over points being determined by the ratios of the arms of the levers 5, 10.
