Abstract: 876,178. Milling. STOCKHOLMS HARDMETALL-MANUFAKTUR HAMA A.B. Dec. 27,1957, No. 40197/57. Class 83 (3). Means for setting a blade in a milling cutter comprises both a template 19 and a feeler 13 for contacting the blade. Each blade has a screw 24 bearing on the bottom of the slot 30 in the body 6. With the cutter clamped on a mounting 2 by a wing nut 7 so that the blade 21 rests against the template 19, the reading of a dial gauge 14, which measures the displacement of the rod 13, is noted. The cutter is then swung round until the blade 20 can be rocked to engage the template 19. Next, a ring nut 29 is rotated to move a rod 15 against the blade to displace it axially until the dial gauge registers the previously noted reading. Screws 23 are finally tightened to clamp the blade in position. The rod 13 may be replaced by an oscillating lever or a rod sliding in a direction parallel to the edge of the template 19.

Abstract: 947,928. Automatic temperature control. MONSANTO CHEMICAL CO. July 28, 1960 [Aug. 14, 1959(3)], No. 41622/62. Divided out of 947, 927. Heading G3R. A heater 53 for maintaining a block at a predetermined temperature is fed from an A.C. source 37, negative half cycle current through a diode 63 being adjusted such that enough heat is applied to the block to maintain it slightly below the required temperature. The additional heat required is supplied by the heater when a thyratron 21 conducts during positive half cycles of current in response to a signal from a bridge 11. This signal is generated when a thermistor 12, associated with the block, senses that more heat is required. The signal is substantially in phase with the thyratron plate voltage and after phase shift by a network 19 into precise alignment with the plate voltage, is amplified by a transistor 18 and applied to the thyratron control grid. When the block temperature rises to the desired value, the signal from the bridge 11 drops to zero and then reverses in phase, relative to the thyratron plate voltage, and the thyratron ceases to conduct. The system may be used as a temperature control in the process of hot drawing of nylon yarn.

Title: Process for the production of organo-fluorosilicates
Inventor: MULLER RICHARD
IPC: C07F7/12
Filed: 1965-10-01
Abstract: Organo-fluosilicates are prepared by the fluorination and complex formation in one step of organo-silicon compounds, excluding organotrihalo and organo-halo-hydro-silanes, with alkali metal or ammonium fluorides, the organo-silicon compounds being those trifunctional compounds in which the ligands are replaced by fluorine by the fluorination agent. When an organosilicon compound, the ligand of which is alkoxy, aryloxy or the anion of a weak acid is used the hydroxyl ions formed may be neutralized either by the addition of a calculated amount of hydrofluoric acid or by the use of bifluorides instead of fluorides. Suitable organo-silicon compounds are trialkoxy-silanes, silthianes and silyl esters.  Examples describe the preparation of K2[CH3SiF5], K2[C3H7SiF5] and (NH4)2[CH3SiF5].

A moving blade 11 which may be that of the oil switch of Specification 936,141 has contact fingers 11a joined by springs 11c which maintain pressure between the tips 11b and a fixed contact 10a<SP>1</SP> for normal currents, the length of fingers 11a being such that the electromagnetic interaction between the currents in fingers 11a exceeds the opposing action between the currents in members 10a<SP>1</SP>, 11a, thus increasing the contact pressure during fault conditions. The separating action between members 10a<SP>1</SP>, 11a is reduced by using a plurality of contact fingers and similar action between the blade 11 and a fixed conductor 12 at the blade hinge 13 is prevented by providing the latter with a spring contact-closing force. When the blade 11 is opened a limit spacer (not shown) maintains the fingers 11a apart. The fingers may be made of different material to unbalance their currents and alter the electromagnetic force between them.

Abstract: 1533767 Data processing systems INTERNATIONAL BUSINESS MACHINES CORP 13 Oct 1976 [18 Dec 1975] 42462/76 Heading G4A In a data processing system which includes multi-level storage, one of the higher levels L1 comprises a data store 14 and a smaller capacity auxiliary store 18, the latter being arranged to record changes introduced into the data at that level by a processor 10. The order in which such charges are first made is recorded in a journal 20, and the changes are copied back to the next lower storage level 34 in the same order, copy back being forced if the auxiliary store approaches an overflow condition. Normally copy back can occur whenever data store 14 is free. Forced copy back can occur in a number of circumstances besides auxiliary store overflow. A counter 70, Fig. 2, is advanced for each entry made in the auxiliary store 18 and journal 20 so as to point to the next free space. Similarly a copyback counter 76 is stepped for each copy back operation to point to the next data unit to be copied back. An up-down counter keeps track of the amount of unusual space in the auxiliary store to initiate a forced copy back operation when the unused space falls below a preset amount. Copy back may be continued until the unused space has increased to another preset amount. A virtual address supplied by a processor 10 is hash coded to address a congruence class of four virtual addresses in the L1 directory and is compared at 54 with the virtual addresses read out from the directory. A 2-bit signal identifying a matching virtual address is combined with other hash coded and address bits to access the L1 data store 14. When data is to be written into the L1 store, the hashed address and a validity bit are used to associatively search the journal, and if there is no hit, i.e. the data concerned has not been previously modified or is invalid, an entry is made in the copy back store 18 and the journal at the address pointed to by counter 70. Whenever copy back takes place the appropriate validity bit in the journal is set to 0. The directory also includes status bits which indicate whether the data associated with the virtual addresses have been changed, and these status bits may be used to force a copy back when the data at all virtual addresses in a congruence class have been changed. At levels L2 and L3 the directory and journal are part of main store, and in addition a high speed directory look aside table (DLAT) is provided. Level L4 is formed by magnetic disc units 38 and level L5 by a magnetic tape cartridge unit 40. The disclosure is identical to that of Specification 1,533,768.

The regulators are so matched that the pressure at the. outlet of regulator 11 is less than that at the outlet of regulator 3, with the regulators being subsequently adjustable to ensure a constant pressure at the point P in the flow path to the detector. The restrictor 7 can take the form of a capillary tube, a porous metal block or sinter or a partition having a small hole therein. If instead of the mass detector 9, which could take the form of a flame ionisation detector, it is desired to use a concentration detector such as a katharometer (16, Fig 2, not shown), the column 5 is connected to the source through regulator 3 whilst the regulator connected to the point P is provided with an atmosphere vent (17) instead of being connected to a carrier gas source.
