Title: Improvements in or relating to striking clocks
IPC: G04B21/08
Filed: 1953-06-18
Abstract: 782,341. Clocks. JUNGHANS AKT.-GES., GEB. June 18, 1953 [July 26, 1952; Aug. 2, 1952], No. 16884/53. Addition to 716,714. Class 139 [Also in Group XXXVIII] The striking mechanism described in the parent Specification is modified in that the rod gong and the diaphragm are arranged on a common mounting and in that the diaphragm is built into a two-part chassis having sound radiating openings and supporting the gong block. In the first embodiment, Figs. 1 and 2, the diaphragm 3 is secured at its outer edge to two chassis members 1, 2 by hollow rivets 4. The member 1 has transverse sound apertures 1a and the member 2 an opening 2a for the diaphragm. The gong block 6 is fixed by a screw 11 to a flat stamped sheet metal spring 7 secured by rivets 8 to an angle member 5 secured to the chassis member 2. The member 5 has flanges 5a which cooperate with lugs 6b on the gong block 6 to prevent excess movement of the block and diaphragm during transportation. If desired a piece of sound permeable material could be stuck on the member 1 as protection against dust. In a modification, Figs. 5-8 (not shown) the sound intensity is variable by the provision of sound damping elements which may be located either between the hammers and the gong rods or moved away from the hammers. In another modification, Figs. 9 and 10, a slotted shutter 201 is mounted on rivets 203 and is held by spring washers 204 between the slotted chassis member 200 and the diaphragm. The shutter 201 is movable by a handle 202 so that the slots 200a in the member 200 may be uncovered to varying extents so varying the sound emission. A cloth or felt covering could be placed between the members 200, 201 so rendering the spring washers 204 unnecessary. In this case the extent 'of movement of the' shutter 201 would be limited so as not to completely close the apertures 200a. In another example, Figs. 12 and 15, the diaphragm 320 is secured at its outer edge to a chassis member 301 fixed by screws 303 to the rear wall 302 of the clock case. Posts 305 extend from the chassis 301 to support the clock movement 306. A pillar 307 of the movement'extends at 308 into a bore 309a of the front wall 309 to prevent excess movement of the clock mechanism during transportation. The gong block 312 is con-' nected to the diaphragm by the pin 319 and is fixed to a stamped spring 313 screwed to a stirrup 315, Fig. 16. An extension 312a of the gong block passes through an opening in the flange 315a of the stirrup and co-operates therewith to prevent excess movement of the gong block and diaphragm during transportation. During transportation the gong rods 311 are clamped by lugs 321a, 321b of a pivoted lever 321 and the hammers are clamped by wires (not shown) riveted to the lug 321c of the lever 321. Specification 782,342 is referred to.

Title: Improvements in or relating to devices for measuring very low gas pressures
IPC: G01L21/00
Filed: 1954-06-11
Abstract: 757,147. Discharge apparatus. PHILIPS ELECTRICAL INDUSTRIES, Ltd. June 11, 1954 [June 15, 1953], No. 17218/54. Class 39 (1). [Also in Group XXXVI] A device for use in the measurement of very low gas pressures comprises a vessel adapted to be filled by the said gas and containing means including an electronemissive cathode and a grid electrode for producing an electron beam, a collector electrode for collecting ions produced in the gas and a fourth electrode for collecting electrons produced in the gas, the proportion of electrons collected by the said fourth electrode when the device is in operation being variable and dependent upon the potential difference between the cathode and the said collector electrode. The tube shown comprises a filamentary cathode K and a helically wound grid G surrounding a filamentary collector C and a fourth anode electrode P in the form of a plate. A microammeter A and a potentiometer resistor are connected between the grid G and the anode P, and the sliding contact of the resistor is connected to a positive supply terminal. The collector C is connected through a capacitor to a point of fixed potential, for example to earth. Means are provided for so charging the capacitor as to hold the collector negative with respect to the cathode so as to exert a deflecting influence on the electron beam and thus control the distribution of electrons between the grid G and anode P. Since the collector collects the positive ions, the negative potential will gradually decrease in value at a rate depending on the pressure of the gas. This rate can be measured, preferably by measuring the time taken by the collector, after the capacitor has been charged, in resuming its initial potential at which the voltages at the grid and anode are equal, which condition is indicated by the microammeter. Alternatively, after charging the capacitor, the sliding contact of the potentiometer may be displaced at such a speed between the grid and anode that the microammeter reading remains constant, the rate at which the contact is moved providing an indication of the degree of vacuum. In an alternative arrangement, the tube comprises a planar grid electrode mounted between a plate anode and a filamentary cathode and collector electrodes. The collector electrode is connected through a resistor to a point of negative potential and the grid and anode electrodes are connected through individual resistors to points of positive potential. An instrument connected between the grid and anode electrodes measures the current distribution between the electrodes which is a measure of the gas pressure. In a modified arrangement the anode is formed by two interconnected plate electrodes arranged one at each side of the plane containing the cathode and collector electrodes. In this case the anode current increases in absolute value as the negative potential of the collector electrode decreases. The ends of the filamentary cathode inside the envelope may be surrounded by an earthed screen.

Title: Improvements in or relating to a process for the manufacture of mercaptans
Inventor: COATES HAROLD
IPC: C07F9/17
Filed: 1958-06-02
Abstract: Alkyl mercaptans are prepared by heating an inorganic salt of a dialkyl dithiophosphoric acid containing two alkyl-oxygen-phosphorus linkages to effect an isomerisation to produce a salt of a dialkyldithiophosphoric acid containing two alkyl-sulphur-phosphorus linkages, which is thereafter hydrolysed to liberate a free mercaptan.  The dialkyldithiophosphoric acid salts used as starting materials are prepared by reacting an alkanol with P2S5, the alcohol preferably being a primary alcohol, and then reacting the resulting dialkyl dithiophosphoric acid with an alkali metal, alkaline earth metal or inorganic base, desirably using sodium sulphide in the presence of an antifoaming agent.  The isomerisation is suitably effected in an inert organic polar solvent, e.g. a phenol.  The hydrolysis may be effected by heating with aqueous mineral acid. Examples describe the conversion of (1) lauryl alcohol to lauryl mercaptan and a mixture of lauryl thioether and dilauryl disulphide, which mixture is reduced with zinc and acid to yield more lauryl mercaptan; (7) butanol to butyl mercaptan; (8) isooctanol to isooctyl mercaptan and (9) cetyl alcohol to cetyl mercaptan, the isomerisations being effected at temperatures ranging from 138 DEG to 220 DEG C.
