Title: Improvements in the Manner of Securing Together the Parts of Boxes, Furniture, Aircraft, Vehicles and other Articles.
Inventor: MOLLOY PATRICK
IPC: F16B3/00
Filed: 1918-07-08
Abstract: 130,722. Molloy, P. July 8, 1918. Bodies.-Parts of boxes, carriages, or vehicles &c. are secured together by a number of headed dowels d, Fig. 3, which are fixed in position by headed transverse pins d' passing through holes in the dowels and in the parts connected. The dowels may be hollow, as at a, Figs. 8 and 10, or solid, or partly hollow and partly solid, and may be screw-threaded on the outside; the transverse holes c in the dowels may be screw-threaded. The transverse securing pins d<1>, Fig. 12, may have screw-threaded, plain, or pointed ends g and may be solid or hollow. The heads of the securing-pins may be circular and with grooves or recesses for holding or turning purposes; or they may be of polygonal form. The transverse holes in the parts to be secured may be bushed with metal or hard wood. A single transverse securing-pin may be used for a series of d.owels in line, and when two pieces of thin sheet material are to be joined to a thicker piece, telescopic double-headed dowels are employed, the securing-pins passing through both portions of the dowels.

Title: Improvements relating to measuring apparatus
Inventor: SHEPHERD ALEXANDER TURNBULL
IPC: G01D5/26
Filed: 1963-03-21
Abstract: 993,072. Electric selective signalling. FERRANTI Ltd. March 11, 1964 [March 21, 1963], No. 11165/63. Heading G4H. Signals are derived representing the extent and sense of the movement of an object by laser means tuned to a predetermined frequency and having light sensitive means arranged to produce two signals, a mirror or mirrors at the other end attached to the moving object so as to reflect back part of the radiation from the laser means, movement causing amplitude modulation of the signals, the signals being representative of two optical paths of slightly different lengths from the laser means to the moving object and back so that the signals are in quadrature phase, the timed relationmovement being indicated by the timed relationship between the two signals. In Fig. 2 a worktable W of a machine tool carries two mirrors R1, R2 each co-operating with a laser L1, L2. The lasers are tuned to the same frequency and each has a photo-cell P1, P2. The mirrors are placed so that the difference in distance is one-eighth of the wavelength. As the work-table moves the signals from the two photo-cells are amplitude modulated sinusoidally and are phase displaced by a quarter wavelength. The cycles are counted at E. The counter may be controlled as in Specification 760,321 to count forwards or backwards according to the direction of movement as is indicated by the time relationship between the two signals. The quarter wavelength phase displacement may alternatively be produced by a compensating plate or by shifting the lasers, the mirrors R1, R2 being aligned. To avoid using two mirrors, a single mirror R3, Fig. 3, may be used, the two optical paths coinciding between mirror R3 and half-mirror 22. Mirror 21 reflects light reflected from half-mirror 22 to laser L1, one beam is delayed a quarter wavelength by plate C. To avoid interference between the two beams they are polarised at right-angles by transparent plates 23, 24. To avoid disparities due to changes in the parameters of the Lasers they may be arranged to share the same gas filling, the same excitation and the same resonator mirrors. In the form of Fig. 5 a single laser L3 is used on a time-sharing basis, the optical path to the mirror being short or long according as to whether delay device is energized. This is controlled by a generator 42 which provides a square-wave signal. The output of photo-cell P3 is switched to lead 44 or lead 45 by the generator 42 so that one lead receives signals relating to the short path and the other to the long path. The resultant signals (Fig. 6) are smoothed to obtain the two quadrature displaced signals. A double laser as shown in Fig. 4 may be combined with a timesharing arrangement as shown in Fig. 5 to produce four signals each displaced by 90 degrees from the next. The photo-cells may be placed at the other ends of the lasers but this is less convenient.

Title: A process of silylating organic compounds
IPC: C07F7/18
Filed: 1954-04-15
Abstract: Organic compounds containing one or more functional groups - XH with or without one or more functional groups -XM, where X is oxygen or sulphur and M is a metal, are silylated by reacting with a mixture of a chlorosilane R3SiCl and a silazane (R3Si)2NH, where R is an alkyl group of less than 7 carbon atoms or a phenyl group, the relative amounts of the reactants being such that the mixture is maintained in a neutral condition throughout the reaction.  The reaction proceeds spontaneously but heating to below 100 DEG  C. may be applied. A solvent such as benzene, toluene or pyridine may be used.  Organic compounds which may be silylated include carboxylic acids, alcohols, mercaptans, phenols, sulphonic acids, sulphate esters, phosphate esters and phosphonic, phosphonous and phosphinous acids.  They may also contain other groups such as amide, ester, nitrile, halogen, nitro and carbonyl groups and sulphide, acetal, ester, ether, C=C and C­linkages.  Particularly useful compounds are biologically active substances.  When silylated, they are readily hydrolysed by moisture to the original substance. In the examples: (1) the sodium salt of heparin is reacted with hexamethyl-disilazane and trimethylchlorosilane: (2) the potassium salt of penicillin G and (3) the antibiotic erythromycin are similarly silylated; (4) 2 - (p - chloro - a  - methylbenzyl) - 4 - chloro phenol is reacted with an equimolecular mixture of trimethylchlorosilane and hexamethyldisilazane to give <FORM:0760059/IV(a)/1> (5) allyl mercaptan is similarly silylated giving the compound (CH3)3SiSCH2CH=CH2; (6) equivalent results are obtained using mixtures of phenyldimethylchlorosilane and diamyltetramethyl disilazane.ALSO:Antibiotics are silylated to form products which are readily hydrolysed by moisture back to the original substances, by reacting the compounds with a mixture of a chlorosilane R3SiCl and a silazane (R3Si)2NH, where R is an alkyl group of less than 7 carbon atoms or a phenyl group, the relative amounts of the reactants being such that the mixture is maintained in a neutral condition throughout the reaction.  The reaction proceeds spontaneously but heating to below 100 DEG  C. may be applied.  In the examples (2) the potassium salt of penicillin G containing one mol. of water of hydration is reacted in ether with a mixture of trimethylchlorosilane and hexamethyldisilazane giving a glass-like solid having one trimethylsilyl group per penicillin molecule; (3) erythromycin is heated in benzene with an equimolecular mixture of trimethyl chlorosilane and hexamethyl disilazane giving a compound having about 2 trimethyl silyl groups per molecule which is tasteless.
