Title: Improvements in and relating to the manufacture of sugar direct from the juice
IPC: C13B20/18
Filed: 1920-12-06
Abstract: 178,488. Delafond, E. Dec. 6, 1920. Liquids, treating; cells; electrodes; electrolytes, circulating.-Sugar juices and syrups are purified by passage between electrodes at a speed sufficient to prevent deposition on the electrodes. The speed is preferably about 5 metres per minute, but may be as great as one metre in 5 seconds. The current density should be low enough to prevent inversion of the sucrose, for example 1/100 to 1/50 amperes per sq. cm. A total current of 10 to 60 amperes and a pressure of 6 to 10 volts may be used. Alternating current may be used. The liquid should not be subjected to the current for more than five minutes. The juices are preferably acidified slightly with sulphurous or phosphoric acid. The temperature is kept below 71‹ C. The apparatus shown consists of a wooden or other tank 1 containing electrodes 2, 3, 4 of zinc, carbon, and aluminium respectively connected to a three-phase system. The electrodes are staggered to form a zig-zag passage for the liquid, and are about 50 cm. apart. The liquid enters by a trough 8 and clear juice is drawn off by a pipe 9. Scum may be skimmed off or may pass off by a spout 12 to a filter. Sediment passes through a slot 10 to an overflow chamber 11, from which it may be led to a settling-tank and decanted, the residue being pressed and filtered to recover remaining juice; alternatively the whole product may be passed directly to a sand filter.

Title: Improvements in or relating to mounting needle rolling bearings
IPC: F16C43/04
Filed: 1969-07-11
Abstract: 1,269,565. Assembling bearings. NADELLA and A. PITNER. 11 July, 1969 [12 July, 1968], No. 34959/69. Heading B3U. [Also in Division F2] Needle roller bearings are assembled by expelling from a sleeve 6 a ring of needles 7 having at each end an abutment washer 8, 9 and positioning the needles and washers in a bore 3 in a supporting element 1 with an axial clearance between the washers and needles. The needles and washers are expelled from the sleeve by exerting an axial thrust on one washer until the washer occupies its correct position in the bore. The axial clearance is produced by exerting a further axial thrust on the other washer either directly or via the needle rollers. An apparatus for assembling the bearing comprises a mandrel which is composed of an inner 18 and outer element 11, the outer element having a thin cylindrical tube 15 which is adapted to engage the washer 9. The inner element 18 is coaxial with the tube 15 and is provided with a shoulder 22 which engages the ends of the needles. The mandrel elements are mounted within a support 12 by springs 16 and 21. On operation of the apparatus the tube 15 engages the washer 9 and forces the needles and washer from the sleeve into the bore. The member 13 is arranged to prevent further movement of the outer element when the washer 9 is in its correct position. The spring 16 is then compressed until the spring 21 engages the mount 12 and the inner element of the mandrel is forced downwardly, thereby axially displacing the needles and lower washer 8. In another embodiment, (Fig. 5, not shown) the shoulder 22 is omitted and a rubber element 25 is provided to engage with the needles.

Title: Digital data retrieval system with dynamic window skew
IPC: H04L25/49
Filed: 1973-07-23
Abstract: 1424268 Digital storage systems BURROUGHS CORP 23 July 1973 [1 Nov 1972] 35090/73 Heading G4C A read-out circuit, for reading binary data from a magnetic recording medium in which a bit of one state is recorded as a flux transition at the centre of a bit cell and a bit of the other state as a transition at the beginning of a bit cell except where such a bit immediately follows one of the first state, includes means for generating "window" signals which encompass the transitions. The window signals are phase shifted in response to an error signal indicative of the varying degree of displacement of the transitions from their correct positions in the bit cells as dictated by a data-derived clock signal. Data signals b, Fig. 4, are read from the magnetic medium and clock signals a are generated by a voltage controlled oscillator in a phase lock loop fed from the read head. The data signals are displaced by #E from their correct positions in the bit cells, and each triggers a first monostable (55, Fig. 2, not shown) which has an astable period equal to half the clock period, as shown at c. The data signals also trigger a bi-stable (59) which is reset by the immediately succeeding negative-going flank of the clock signal, as shown at d. Signals c and d pass to a summing differential amplifier (61) which consequently delivers signal e. Signal e is smoothed by a filter (63) to provide a phase error signal f which adjusts the astable period of a second monostable, triggered by clock signals at half the rate of a. The second monostable's output triggers a third monostable which has a fixed astable period and delivers window signal h. The window signals are passed, together with the data signals b to a decoding unit which delivers the decoded data.
