Patent GB-111984-A (GB)
Title: Improvements in Milling Machines.
Inventor: ELLERY ROBERT LUCAS
IPC: B23C3/32
Filed: 1917-07-26
Abstract: 111,984. Ellery, R. L. July 26, 1917. Milling helical surfaces.-Fig. 3 is a longitudinal section of a machine for milling the grooves in drills, reamers, &c. The work A is carried by a rotating spindle 26, but, if straight grooves are to be cut, does not rotate with it, and is supported in a steady 55. The spindle is rotated by worm gear and is caused to advance by grooves 28 engaging pins in the bearing bush 22. The base 1 is of segmental form in plan so that the table 2 can be turned about the pin 3 and secured at any angle to the fixed cutter-spindle to cut helical grooves of the desired pitch. The work spindle 26 is carried on a table 8 pivoted to the lower table 2 at 9 and supported on a wedge-piece 11 resting on an inclined base 7 on the table 2. Between the wedge-piece 11 and the table 8 is a plate 12 which slides in inclined grooves 13 in the table 8. This plate is secured to a rod 56 which is supported at the other end by a bracket carried by and moving with the work spindle. Thus, as the work is fed under the cutter, the table 8 is allowed to fall slowly so that the groove cut is tapered. When the groove has been cut to the desired length, a wheel 41 on the work spindle actuates a knock-off gear and withdraws a latch holding the wedge-piece 11 in place. The spring 18 then pushes out the wedge and the table 8 falls and moves the work out of contact with the cutter. Later, the wheel 41 disengages the worm from the worm-wheel and the rotation of the work stops. The work spindle is then reversed by hand, and when the collar 60 makes contact with the bearing-bush 22 the latter is rotated and lifts a locking-latch 25 which engages a second notch in the bush and locks the work in position for the cutting of a second groove.

Abstract: 986,791. Programming arrangements for electronic computers. HOLLANDSE SIGNAALAPPARATEN N.V. March 24, 1961 [March 29, 1960], No. 11011/60. Heading G4A. Conditional jumps in the program sequence of a stored program computer are effected by modifying the contents of that part of the instruction word (which is called from memory 1 into a set of registers 2-5) which gives the "next instruction" address and is read into register 5, in accordance with the contents of one or more of a number of decision registers 9-11. Any of these (bi-stable) registers may have been chosen to be set in accordance with the result of an earlier program step on line 14 by an input selector 8 controlled by the "condition" register 4, which also selects through output selector 12 the appropriate decision register for modification of the address from register 5 in register 6. If a conditional jump is required immediately the signal from 14 is selected by unit 12, no decision register being required. Inputs 18 and 19 may be selected (instead of line 14) by a selector 7 to enable a decision register to be set when a particular program step is carried out. If the jump is to depend on the state of more than one of the registers 9-11 the selector 12 examines the state of one of the output lines of a diode matrix 13 have inputs from the three registers. Fig. 5 (not shown) illustrates schematically units 4, 7-11 and part of 12; in fact showing 14 decision registers selected by four bits of a 7-bit instruction in register 4, other bits being used for selecting an output of the matrix 13 rather than a single decision register output (Fig. 6, not shown, which also illustrates registers 5 and 6 and the direct connection from line 14 to register 6).

Title: Improvements in or relating to Steam Turbines.
Inventor: QUIBY HENRI
IPC: F01D1/02
Filed: 1919-05-03
Abstract: 126,622. Quiby, H. May 4, 1918, [Convention date]. Regulating. - Relates to means for regulating multi-stage turbines in the low-pressure stages of which steam from two different sources is used. The steam space of stage 2, which can receive steam from the preceding stage 1 through a space 13 or live steam through a pipe 12 and valve 11, is divided into three chambers 6, 7, 8 interconnected by valves 9, 10. For lowest speed, the valves 10, 11 are closed, and the steam from the stage 1 is led to the stage 2 partly through nozzles 14 and partly by way of the chamber 6, valve 9 and chamber 7 to nozzles 15, For higher speed, the valves 9, 10 are closed and live steam is supplied to the stage 2 through the valve 11. At full speed, the valve 9 is closed, and live steam flows through the valve 11 to chamber 7 and through the valve 10 to chamber 8, thereby impinging on or about two-thirds of the circumference of wheel 2. For a greater overload, the valves 9, 10, 11 are opened. No steam impinges on the wheel 1 in the last three modes of working. The invention is applicable also to mixed-pressure turbines wherein live steam is supplied to the stage 1 and exhaust steam from a power installation to the pipe 12.

Filed: 1967-03-10
Abstract: 1,150,128. Transistor oscillating circuits. VYZKUMNY USTAV MATEMATICKYCH STROJU. 10 March, 1967 [12 March, 1966], No. 11326/67. Heading H3T. An oscillator, Fig. 1a, comprises at least three logic elements I 1 , I 2 , I 3  coupled into a ring by means of non-linear elements 04, 05, 06. Assuming a signal 1, Fig. 1b on the base of transistor T1, then if the charge storage is arranged to exactly double the width of the pulse, the inverted output at the collector will be as shown at 2, that is the effect is as if the pulse were delayed by onethird of a cycle. If this is repeated by the two other stages, the resulting output 6 is in the correct phase to provide positive feedback to the input 1. Diodes D4, D5, D6 provide isolation during charge storage time so that this time is determined solely by the elements P, Q which may be active or passive. P and Q may be omitted and by suitably modifying the non-linear elements sawtooth or sinewave outputs may be obtained, Fig. 3 (not shown). Pulse modulation may be effected by the circuit of Fig. 2a. With a high level output from source Z, transistor T10 is conducting to earth the output from T9 and hold T4 cut-off. T1, T2, T11 then operate in the manner described above. When the output from source Z is at a low level a further oscillatory loop is completed from transistor T9 via T4 round to T1 to modify the frequency of the oscillator, Fig. 2b (not shown). A number of similar oscillators may be kept in a required phase relationship by connecting the outputs from appropriate stages round the loop. The oscillator may be formed as an integrated circuit.

Title: Method of stabilizing a spice extractive and the resulting product
Inventor: RAYPEAT MACLYN
IPC: A23L27/00
Filed: 1963-03-22
Abstract: A spice extractive carried by a particulate, ingestible solid carrier material containing a metal consituent which normally catalyses deterioration of the spice extractive, is stabilized by treating the carrier material with a small amount of a metal deactivater consisting of an edible water soluble salt of ethylene diamine tetra-acetic acid sufficient to cause the metal constituent contained in the carrier material to complex against metal-catalysed deterioration of the spice extractive when combined with the solid carrier material and combining the spice extractive with the solid carrier material.  Carrier materials: sugar or common salt.  Spice extractives particularly mentioned: oleoresins paprika, capoicum, marjoram and basil.  The preferred metal deactivater is the calcium chelate of the di-sodium salt of ethylene diamine tetra-acetic acid, when present in a concentration of from 0.001% to 0.05% by weight based on the weight of the carrier material.  An edible antioxidant is preferably distributed throughout the spice extractive in a concentration of from 0.001% to 2.0% by weight based on the weight of the spice extractive.  Antioxidants mentioned are conventioned antioxidant compositions based on N.D.G.A. and B.H.A.  In examples, the efficacy of the di-sodium salt of ethylene diamine tetra-acetic acid and of the calcium chelate thereof in stabilizing spice extractives is demonstrated utilizing a colour standardization procedure.  In comparative experiments, the effects of citric acid, stearyl acid phosphate and di-sodium acid phosphate were studied. Reference is made also to the incorporation of spices upon carriers such as dextose, calcium silicate, magnesium carbonate and cellulose.
