Title: Improvements relating to x-ray apparatus
Inventor: WILD CHARLES HENRY JAMES
IPC: A61B6/08
Filed: 1956-10-11
Abstract: 854,762. X-ray apparatus. DEAN & CO. (X-RAY APPARATUS) Ltd., A. E. Oct. 11, 1957 [Oct. 11, 1956], No. 30988/56. Class 98(1) Apparatus for indicating the field to be irradiated by an X-ray beam includes a housing which is placed between an X-ray tube and an aperture defining the field and which carries an official device which forms an image of the field as viewed from the tube focus. and through the aperture. As shown, a housing 1, lined with lead, is fixed at one side to an X-ray tube 2 and at the other to a housing 4 for a lead leaf diaphragm 5, 6. A tube 8 projecting from housing 1 contains an object lens 9 and a viewing lens 10, to which light passing in through the diaphragm is reflected by a mirror 11, which is either transparent to X-rays or movable out of the beam before exposure. The tube 8 and mirror 11 may be fixed or, as in the example shown, tiltable. The mirror frame is fixed to a pair of sleeves 14a rotatable on fixed spigots, and the tube 8 is carried by a member 16, having an arcuate portion sliding over a similarly-shaped part of the housing. Member 16 is mounted on a pair of arms 15a, pivoted on the sleeves 14a, and having upturned ends carrying pins 19 engaging slots 20, formed in bellcranks 21 pivoted at 22. The other arms of the bell-cranks are connected by links 23 to levers 24 clamped to the sleeves 14a. The positions of the pivots of the bell-cranks are so chosen that the angular movement of the mirror 11 is half that of the tube 8. Spring-pressed friction discs hold the parts in any adjusted position. A lead-glass filter may be mounted in tube 8. The image is laterally reversed, but may be reversed again by a further lens. Cross lines may be provided on the lens 10, and a transparent plate 25 at the bottom of housing 4 has a central spot 26 which the operator aligns with the cross lines to eliminate parallax error. Alternatively lens 10 is replaced by a ground glass screen, having cross-lines, and on which the image is formed and viewed directly. Where a cone or hood is used instead of a diaphragm the mirror 11 may be mounted in the cone or hood with the tube 8 projecting from the side.

Patent GB-315022-A (GB)
Abstract: 315,022. National Cash Register Co., Ltd., (National Cash Register Co.). April 11, 1928. Adding and subtracting apparatus; clear signals.-The clear, positive or negative condition of an adding and subtracting totalizer is indicated by means of plates automatically shifted under the control of the totalizer and the total-taking mechanism. When the totalizer is clear or contains a positive quantity a plate is positioned to exhibit the word " clear " or " plus respectively, but when the amount of the totalizer becomes negative another plate bearing the word " over " is moved to show this word and obscure the first plate. The invention is illustrated as embodied in the cash register described in Specifications 8119/15 and 176,781. The " clear-plus " plate 150, Fig. 15, pivoted at 151, is operated by an arm 155 spring-coupled to another arm 171 that is provided with a stud 173 and is limited in counterclockwise movement by abutment against a stud 156 on the arm 155. Assuming the plate is showing " clear " the movement of the totalizer into engagement for an adding operation effects, through the totalizer frame 76 and a pivoted yoke 158 provided with a lug 159 to engage the stud 156, the counterclockwise rocking of the arm 155 to exhibit the word " plus." If, on the other hand, the totalizer is to be cleared, the setting of the total lever for this purpose lowers a link 167 to bring a lug 175 on a yoke 169 against the stud 173 so that when the total-taking mechanism operates to lower the link still farther the lug rocks the arm 155 clockwise to exhibit the word " clear." This action occurs before the totalizer is moved into engagement so that the subsequent movement of lug 159 will result only in a momentary rocking of the plate and the parts will then return due to the spring coupling between the arms 155 and 171. If the totalizer is to be read only, the movement of the totalizer into engagement and therefore of the lug 159 takes place prior to the automatic actuation of link 167 and consequently the indication of " plus " is not changed. When. the totalizer is positioned for subtraction and is overdrawn the highest subtraction wheel 54, Fig. 11, through its long tooth 180 unlatches an arm 186 a spring-coupled extension 191 of which is thereupon latched at 196. When the totalizer moves out of engagement therefore a stud 208 on its frame cams an arm 209 to the left to rock an arm 213 by means of a link 212 and thus place an " over " signal 165 between the clear-plus indicator and the viewing window. If the 'totalizer should again change sign to positive a long toothon the highest positive wheel produces unlatching of arm 186 and a similar stud 243 becomes effective on the arm 209 to rock the indicator 165 to obscured position. Means including the usual transfer-restoring plate 240 and cam-rocked arms 220, 230 are provided to re-latch the arm 186, and unlatch the arm 191 and to prevent interference of the arm 209 with the studs 208, 243 when the totalizer frame shifts axially.

Title: Process for the preparation of surface-active salts of n-acylamino-carboxylic acids
Filed: 1957-10-09
Abstract: Surface-active compounds are prepared by heating a salt of a N-acylaminocarboxylic acid of the general formula: R-CO-[NH-(CH2)n-CO]x-OMe (wherein R is the residue of a carboxylic acid containing at least 8 carbon atoms, n is a whole number from 3 to 7, x is a whole number from 1 to 10 and Me represents an inorganic or organic base) with ethylene oxide at a temperature of at least 100 DEG C.  In Example 1, the sodium salt of stearylaminocaproic acid (0,5 mol) is heated to 120 DEG C. in a stainless-steel autoclave, equipped with a stirrer under a nitrogen atmosphere at 3 atm. pressure; and liquid ethylene oxide (4 mol) is introduced at such a rate that the pressure does not rise above 10 atm.  The solid product obtained after cooling can be recrystallised from methanol.  In Example 2, palmitylamino-caproic acid (0,5 mol) is reacted with ethylene oxide (3 mol) at a temperature of 120 DEG -130 DEG C. Example 4 gives details of a suitable composition for a washing agent (see Group III).  Specification 858,238 is referred to.ALSO:Washing agents, suitable for use with hard water, are prepared by heating a salt of a N-acylaminocarboxylic acid of the general formula: R-CO-[NH-(CH2)n-CO]x-OMe with ethylene oxide at a temperature of at least 100 DEG C.  In the formula, R is the residue of a carboxylic acid containing at least 8 carbon atoms, n is a whole number from 3 to 7, x is a whole number from 1 to 10, and Me represents an inorganic or organic base.  The products have low foaming capacity, and are suitable for use in washing machines.  The washing agent may be mixed with any of the usual ancillary components such as alkali metal carbonates and phosphates, sodium perborate, the ethercarboxylic or ethersulphonic acids of cellulose or starch, cellulose sulphates, alginates, methylcellulose, glue and gelatine. Example 4 gives details of a suitable composition which contains sodium sulphate, sodium tripolyphosphate and pyrophosphate, and a small percentage of cellulose glycolate.  Specification 858,238 is referred to.
