Title: Differential Absorption Measuring System
IPC: G01J3/42
Filed: 1967-09-21
Abstract: 1,186,623. Measuring light absorption photoelectrically. DURRUM INSTRUMENT CORP. Sept.21, 1967 [Sept.22, 1966], No.43053/67. Heading G1A. The differential absorption of two light beams which fall alternately on a detector is measured by detecting the A. C. component in the detector output and varying the gain of the system in synchronizm with the beam alternation so as to minimize the A. C. component, the gain variation necessary then indicating the differential absorption. The output of photo-multiplier 22a, appears at 57 and depends upon the magnitude of the D. C. shunt comprising selected resistors 46-49 and that part of potentiometer 52 selected by a switch 53. The A. C. component at 57 drives a servomotor 29 to vary the proportions of potentiometer 52 which are connected in the shunt by the switch 53 which is operated in synchronizm with the alternation of the light beams. The relative gain of the system in alternate half cycles is thus adjusted until the output at 57 is substantially D. C. The differential absorption signal may be from circular dichroizm measuring apparatus in which the beam from a variable mono-chromator is polarized by a Rochon prism and coverted alternately to a left and right circularly polarized beam by a Pockels cell before passing through a sample to the detector Fig. 1, (not shown). Alternatively it may be from a dual beam spectro-photometer in which the beam from a variable mono-chromator is split so as to pass alternately through sample and reference chambers to the detector, Fig. 4, (not shown).

Title: Improvements in or relating to Circuit Arrangements for Use in the Measurements of the Attenuation or Gain of Four-Terminal Devices
IPC: G01R27/28
Filed: 1967-09-22
Abstract: 1,197,093. Electrical measuring methods. SIEMENS A.G. Sept.22, 1967 [Sept.23, 1966], No.43148/67. Heading G1U. In a system for measuring the gain or attenuation of a four terminal device at varying frequencies, the device is connected in a test arm and the output from this arm is compared with that from a reference arm when both arms are fed with the same signal, and a calibrated attenuator in one of the arms is adjusted until both outputs are equal, the adjustment representing the gain or attenuation of the device. The arm that does not include the attenuator has connected in it an impedance device whose attenuation/frequency characteristic is substantially the same as that of the attenuator when adjusted to give null attenuation. This saves the need for calibration curves or tables for correcting the test result in accordance with frequency. When measuring attenuation (Fig. 1) the attenuator (J, 6, 7) is in the reference arm, and the impedance device (10) in the test arm. When measuring gain (Fig. 2) the impedance device (10) forms the reference arm and the attenuator (J, 6, 7) is in series with the test device in the test arm. The attenuator incorporates a number of four terminal attenuator stages which may be switched into or out of circuit and is in a common housing with the impedance device, which consists of silvered brass coaxial line sections with inner conductors' of tin bronze.

Title: Method of interbonding glass fibres in a mat
IPC: D04H1/58
Filed: 1964-10-23
Abstract: 1,091,232. Non-woven fabrics. OWENS-CORNING FIBERGLAS CORPORATION. Oct. 23, 1964 [Nov. 22, 1963], No. 43351/64. Heading D1R. Glass fibres are interbonded in a mat by impregnating the mat with an aqueous dispersion of synthetic-resin particles of size between 50 and 5 microns, and heating the mat to drive off water and cause the synthetic-resin particles to stick to the fibres and bind them together. As shown, glass is melted in a tank 10 and drawn into small streams 12 which are attenuated and solidified. They then pass over an applicator 13 for lubricant such as a water solution of distearate condensate of tetraethylenepentamine pelargonate, or even plain water. They then pass over a gathering shoe 14 and between puller wheels 15, and are projected on to a deflector trough 16. This is pivoted and oscillates to deflect the fibres on to but across the full width of the conveyer 18 where they form the mat 19. Alternatively the mat can be made of chopped strands or by steam blowing. The mat then passes beneath the weirbox 22 where a water dispersion of synthetic resin flows down the shoot 23 on to the mat. The conveyer is foraminous and excess dispersion flowing through it is collected in a trough 24 and returned by pump 33 for recirculation. The mat then passes over suction box 25 to remove excess liquid and then through a drying and curing oven 27. The synthetic resin powder may be of a polyester resin, e.g. an ester of diethylene glycol and maleic anhydride, cross-linked with diallyl phthalate, resins formed from a polyol and fumaric acid or linear polyesters, phenol-formaldehyde, ureaformaldehyde, polyvinyl acetate, melamineformaldehyde or polystyrene.

Abstract: 1,048,700. Elevated railways. E. HILL ALDAM & CO. Ltd. Oct. 30, 1964 [Nov. 4, 1963], No. 43454/63. Heading B7L. An elevated railway for suspending flat articles, e.g. partitions in rail vehicles, comprises two rails 12, only one shown, supported by brackets 16, each rail having trolleys 18 each of which carries, on a pivot pin 20 and swivel 21, a support member 40. The member 40 carries through bearings 24, Fig. 2, at least one bar 25, the bars 25 of the two rails 12 being fixed to a track 14 having two wheeled trolleys 30 to which the flat articles are connected by swivel connections. Sliding of bars 25 in member 40 is limited by stops 33, 34 and the base of pin 20. The railway enables a large flat article to be pulled along the rails 12 from one side whereby the article is not at right angles to the rails 12 without the trolleys binding on the rails; the angle made by the article or track 14 with the rails being determined by the positioning of the stops 33, 34. The article can be moved along or swivelled relative to track 14.

Abstract: 1,090,022. Crystallizing from salt solutions. STANDARD MESSO DUISBURG G.m.b.H. Oct. 26, 1964 [Oct. 31, 1963], No. 43621/64. Headings BIB and B1G. In a crystallization apparatus warm solution enters through pipe 12 and is sucked up by a propellor 2 through a guide tube 5 into the upper chamber 7 where evaporation under vaccum takes place at the liquid surface causing cooling of the solution and thereby crystallization. The cooled solution passes downwardly between the guide tube and outer tube parts 9 and 10 so producing a primary flow circuit. Liquid is also sucked through a gap 11 between the parts 9 and 10, this secondary flow mixing with the primary flow. Coarse crystals sink downwardly and are removed through valve 15. Fine crystals are entrained in the upward flow through the circular space 16. The gap 11 is alterable by displacement of the part 10 to maintain the speed of the secondary flow slower than the primary flow. In the lower chamber separation of the solution and salt takes place, the clear solution flowing over 17 to a pipe 18. Alternatively with solutions such as potassium nitrate in a nitric acid solution the cooling vacuum is replaced by indirect cooling, e.g. with brine, circulated through an external heat exchanger (Fig. 2, not shown).

A package 20, heat-sealed in jaws continuously revolving in two planes perpendicular to one another, is formed from a web 5 of flexible material, the contents, e.g. milk, being introduced in sterile conditions. Before the web 5 is inserted in the machine, air heated at 45 and filtered at 47 is supplied by a fan 44 into a covering tube 28, and via a pipe 49 into a pipe 21 through which the milk is supplied. The heater 45 is then switched off and sterile but cooler air supplied by the fan, thereby forming a barrier as it issues from either end of the tube 28. A heater 24 is energized before the web is inserted in the machine and drawn downwards by the sealing jaws. The web is guided through a ring 3 to form a tube 51 the overlapping edges of which are heat-sealed by a pad 7. The inside of the tube 5<SP>1</SP> is sterilised as it passes a quartz cylinder 25 surrounding the heating element 24. The supply of milk is kept at a constant level 22 by means of a float 9.
