Title: Apparatus for photometric measurements and comparisons
IPC: G01J1/22
Filed: 1923-11-08
Abstract: 225,690. Waldram, J. M. Nov. 8, 1923. Comparison photometers are constructed so that one of the luminosities to be compared is seen as a background of graduated brightness from one edge to the other, while the other luminosity appears as two uniformly illuminated patches within the background, Fig. 4. The values of the two luminosities are varied relatively until the part of the background surrounding one patch appears brighter than the patch, and the part of the background surrounding the other patch appears darker than this patch. Light from one source is reflected into the apparatus by a mirror 0 through a lens A, the aperture being controlled by an iris diaphragm B operated by a ring C. This light is received on a ground glass screen D which is viewed through an eyepiece F by means of an inclined silvered mirror E, the centre of which is set off the axis of the lens A to give a field view of graduated luminosity. Parts of the silvering of the mirror E are removed for the observation of the other luminosity viewed through the aperture G. Filters H, J are adapted to be inserted in the paths of the rays when the luminosities are widely different, and are actuated by a knob moving a slide K; movement in one direction placing the filter J in position, and movement in the other direction placing the filter H in position. An extension of the slide K carries a cylindrical scale plate M upon which three scales are engraved, calibrated for each position of the slide K. The scales are at right-angles to the axis of the lens and are observed through an aperture N in the ring C controlling the iris diaphragm.

Title: Improvements in or relating to devices for coupling two co-axial shafts
IPC: F16D43/20
Filed: 1953-10-13
Abstract: 746,871. Magnetic couplings. PHILIPS ELECTRICAL INDUSTRIES, Ltd. Oct. 13, 1953 [Oct. 16, 1952], No. 28166/53. Class 35. A coupling between coaxial shafts 1, 2 comprises a planet pinion .20 rotatably supported on a spindle 17 on a carrier disc 16 on one shaft and meshing with a sun gear 21 on the other shaft. Relative rotation between the shafts and the gears is normally prevented by a magnetic synchronous overload clutch 18, 19 between the disc 16 and the pinion 20 so that the gearing rotates solid. On the driving torque exceeding a predetermined amount the clutch 18, 19 will slip and the pinion 20 planetate to reduce or stop the drive from one shaft to the other. The ratio between gear 21 and pinion 20 is a step-up one so that the torque capacity of the clutch 18, 19 is correspondingly less than the transmitted torque. In a modified arrangement the planet pinion is a compound one which drives one disc of the magnetic synchronous clutch arranged coaxially with the shafts, the other magnetic discs being secured to a sun gear fixed on one shaft.

Title: Improvements in or relating to a method and means of transmission by pulses
IPC: H04K1/06
Filed: 1949-11-03
Abstract: 661,459. Pulse code modulation systems; multiplex pulse signalling; pulse delaying circuits. GLOESS, P. F. M., and LIBOIS, L. J. M. Nov. 3, 1949 [Nov. 13; 1948], No. 28216/49. Classes 40 (v) and 40 (vi). In a communication system in which successive groups of pulses are transmitted at regular intervals, a device is provided for permutating the pulses in each group, according to a predetermined law, which comprises two tapped delay lines the tappings on one being connected to different tappings on the other through unidirectional conducting elements biassed to be normally non-conducting and rendered conducting simultaneously by periodic control pulses. In one embodiment, groups of code pulses such as 34, 35, 36 of a five-unit binary code are applied to the input of delay line 1 correctly terminated by resistance 8 and having its five tappings 41 ... 45 connected through rectifiers 23 ... 27 to non- corresponding tappings 51 ... 55 on the line 14 which is correctly terminated at each end by resistances 15, 16. The rectifiers are biassed to cut-off by a source 18, which is neutralized by a control pulse 21 applied to the rectifiers at the time of receipt of the last code element. At this instant the other code pulses or spaces are arranged to be present at the tappings 42 ... 45 and all the code elements are thus transferred simultaneously to the tappings 51 ... 55 on the line 14, to produce at the output terminal the re-arranged group 34a, 35a, 36a, after the pulses have traversed the line. The group of pulses may be those of the channels of an uncoded pulse multiplex system, the pulse modulation being preserved by known technique. In a second embodiment, Fig. 2 (not shown), the tappings on line 1 are connected to those on a plurality of other lines, which can be brought into operation individually and successively, by applying the control pulse to the appropriate connecting rectifiers. In this way secrecy can be introduced into a communication system by constantly changing the code.

Title: Enzyme formulations for the production of tenderized meat
Inventor: HOGAN JOHN MATTHEW
IPC: A23L13/70
Filed: 1958-12-30
Abstract: An enzyme formulation for use in tenderizing meat by the procedure of Specification 913,202 is a substantially sterile aqueous solution of a proteolytic enzyme, e.g. papain, bromelin, ficin, trypsin or pancreatin, which is free from insoluble matter and has been treated to remove impurities.  The solution may be made by suspending the enzyme in water, clarifying the resulting solution, adjusting the pH to above 7.0 and sterilizing it by filtering off the bacteria.  The solution may be purified by salt fractionation or by fractionation by a solvent such as ethanol. The enzyme may be stabilized, i.e. reversibly inactivated, with hydrogen peroxide.  Reversible inactivation involves addition of inactivating material or removal of activating material, activating materials normally found in crude papain being glutathione, cysteine and succinic dehydrogenase succinate. According to Example I, commercial papain powder is wetted with glycerol and stirred with water containing hydrogen peroxide, the solution is allowed to stand, is then treated with catalase and diatomaceous earth and is filtered through a Buchner funnel, and the filtrate is diluted, treated with sodium chloride, adjusted to pH 7.3, and filtered through a Leitz filter into sterilized bottles, the bottles being kept under refrigeration until used.
