Patent GB-786979-A (GB)
Title: Device for the comparison of intensity of two beams of rays, preferably for infrared spectrometers
IPC: G01J3/42
Filed: 1955-06-03
Abstract: 786,979. Photo-electric radiation measuring devices. PERKIN-ELMER CORPORATION. June 3, 1955 [June 14, 1954], No. 15921/55. Class 40 (3). In a photo-electric device for comparing the intensity of two radiation beams such as are produced in an infra-red spectrometer and in which the beams are interrupted alternately, a second interrupter 90 degrees out of phase with the original interrupts the beams a second time, thus the detector is prevented from responding to unwanted signals. As shown, light from a source S is split into two beams by mirrors 10, 11 and diverted by further mirrors 12, 13 through a standard chamber 14 and test chamber 21 respectively. Further mirrors then direct the beams to an interrupter 20, the lower face of which acts as a mirror. Thus, the two beams pass alternately through a slit 19 on to convex mirror 23, are dispersed by prism 24, reflected through the prism again by Littrow mirror 25, diverted by mirrors 23 and 26 through a motor-driven interrupter 28, 90 degrees out of phase with the original interrupter are redispersed by prism 24 and finally are redirected through exit slit 30 on to radiation detector 32. The radiation detector feeds through amplifier 33 a phase-controlled rectifier 34 fed with a reference voltage at twice the interrupter frequency. Fig. 2 shows at (a) the output of the detector in the absence of interrupter 28 and at (b) the output in the absence of interrupter 20. Io and I are the detector output corresponding to the transmissivity of the two beams. The actual detector output is shown at (c) while at (d) is indicated the double frequency reference voltage which is fed to the phase-sensitive rectifier, the output from which is shown at (e) and which contains a D.C. component proportional to the difference between I and Io. This difference is used to control a servomotor 36 to adjust an alternator wedge 37 in the path of rays RB until what the difference in beam intensities is brought to zero. The wedge travel is recorded as Io-I by recorder 38. An arrangement is described with reference to Fig. 3 (not shown), wherein a modulator has a reference signal of the kind shown at f in Fig. 2 applied to it and produces an output as shown at g in Fig. 2. This signal contains a D.C. output proportional to Io+I and may be used to keep the radiation source constant or to adjust slit width. A further embodiment is described (Fig. 4, not shown) wherein a beam of radiation is passed through a tube containing gas under test, one chopper being situated near the entrance and one near the exit of the tube. The chopper at the outlet corresponds to chopper 20 (V.S.) and has the effect of allowing light from the top and bottom of the tube to pass to the dispersing arrangement and thus of comparing light at two different wavelengths.

Title: Improvements in retarding apparatus
Inventor: LOBELLE MARCEL JULES ODILON
IPC: B64F1/06
Filed: 1953-06-15
Abstract: 760,481. Dashpots. M. L. AVIATION CO., Ltd. June 15, 1954 [June 15, 1953], No. 16421/53. Class 108(3). An apparatus for rapidly arresting bodies travelling at high speeds comprises a bullet shaped plunger 1, a cylinder 2 filled with liquid which is retained by a frangible seal 3 covering the open end of the cylinder, and an annular deflector surface 5 opposite the open end of the cylinder leading into an annular chamber 6 provided around the open end of the cylinder such that when the plunger, which is smaller in diameter than the cylinder, pierces the seal and enters the cylinder it transfers energy to the liquid which is expelled through the annular gap between the plunger and the wall of the cylinder on to the annular deflector surface and into the annular chamber. Preferably the annular chamber 6 is formed in a separate unit 9 which can be screwed on to the cylinder, and the annular deflector surface 5 is formed on an annular member 8 provided with a central bore to allow the passage of the plunger and a sealing ring 15 to form a close seal with the plunger. To enable the member 8 to be removed in order to replace the frangible seal 3 it is held against a shoulder of the chamber 9 by a clamping ring 11 provided with radial dogs which can be engaged behind corresponding dogs on a locking ring 26 secured to the chamber 9. The actual seating of the member 8 in the member 9 is a loose fit and is centralized by means of spring loaded plungers 16 so that the member 8 can yield laterally if the plunger 1 is not central. The cylinder 2 is filled with liquid through a non-return valve 17 and surplus liquid passes out through valve 18 which is normally open but closes when the pressure rises due to the entry of the plunger 1. Although it cannot be seen in the drawing, as only a part of the plunger is shown, the nose of the plunger gradually tapers into a second section which in turn merges into the main body which is cylindrical. The lining 4 of the cylinder is shaped so that the wall of its bore is slightly curved to a large radius as seen in longitudinal section so that the diameter of the bore is gradually reduced at an increasing rate.

Filed: 1954-06-03
Abstract: Polyesters modified by reaction with an excess of a di-isocyanate are reacted with a glycol in which the hydroxy groups are linked by two aromatic ring systems, which may be condensed.  The glycol may be used in a quantity less than that equivalent to the isocyanate groups available, the product being shaped during the reaction, or in more than an equivalent quantity, additional isocyanate being added before moulding.  The glycol may be mixed with the polyester before the polyester is reacted with the diisocyanate.  In a modification the polyester is reacted with a quantity of di-isocyanate less than that equivalent to the end groups of the polyester.  The glycol reaction is then carried out after adding additional di-isocyanate.  Specified glycols are the di-b -hydroxyethyl ether of 1.5 dihydroxynaphthalene and its isomers, the reaction product of two mols. ethylene chlorhydrin and one mol. 4.41-dihydroxydiphenyl-1.11-cyclohexane, naphthalene1.5 - dicarboxylic acid - di - (b  - hydroxyethyl) ester, and diphenyl - 4,41 - di - (b  - hydroxyethyl) ether.  The glycols may also contain urea, urethane, carbonamide or sulphonamide groups. In examples (1) a glycoladipic acid polyester modified with diphenylmethane diisocyanate is mixed with a paste of a propylene glycol adipic acid polyester and 1,5-naphthalene - di - (b  - hydroxyethyl ether).  When the temperature drops the melt is cast into moulds and heated at 100 DEG  C. for 15 minutes and then for 15 hours at 100 DEG  C. after removal from the moulds.  (2) (a) 11 grams 1.5-naphthalene-di-(b -hydroxyethyl) ether acid and 10 grams finely divided silica are added to 200 grams of a glycoladipic acid polyester and dehydrated at 130 DEG  C.  Forty grams diphenylmethane di-isocyanate are added and the mixture cast and after heated for 24 hours at 100 DEG  C.; (b) as in (a) but using different proportions. (3) Similar to (2) but using less di-isocyanate, more di-isocyanate being added by working on a roll before moulding.  (4) 34 grams 1.5 naphthalene di-isocyanate are reacted with 170 grams glycol-adipic acid polyester and a paste of 30 grams of the same polyester and 12.2 grams diphenyl-4.41-di-(b -hydroxyethy) ether added.
