Title: Ultrasonic scanning apparatus
IPC: A61B8/00
Filed: 1971-04-06
Abstract: 1391903 Ultrasonic apparatus NATIONAL RESEARCH DEVELOPMENT CORP 5 April 1972 [6 April 1971] 8847/71 Heading H4D A scanning transducer assembly includes a carriageway rotatable about a first axis fixed relative to a support structure, a first carriage on the carriageway which carries a rotary bearing rotatable about a second axis wherein the carriage is moved along the carriageway and its angular inclination is correspondingly varied to maintain the intersection of the first and second axes fixed and wherein an ultrasonic transducer is journalled in the rotary bearing to project energy along said second axis. Transducer assembly 20 is mounted on a carriage 15a running on an arcuate track 14. A further carriage 15b running on a parallel track 14 carries a counterbalance 21b. In the normal operating mode clutch 41 is disengaged and clutch 43 is engaged. Shaft 42 is thus held stationary by contact with fixed shaft 44, thus holding main shaft 12 fixed. Rotation of motor 31 drives main gear 28 fixed to bush 33 and thus plate 11 rotates. Since shaft 12 is fixed, helical wheels 26a, 26b engage worm 25 to rotate pinions 27a, 27b which engage racks 22a, 22b. Thus the carriages 15a, 15b are driven at equal speeds in opposite directions along the tracks 14. The combined rotations and variation in angle # produces a spiral scan of the transmitter beam. Potentiometers 48, 49 provide signals fed to the display unit 4 to provide a picture of a surface inside the body under investigation, the depth of the surface being selected by range-gating the echo signals. At the end of the arcuate excursions of the carriages 15a, 15b the potentiometers 48, 49 disengage clutch 43 and engage clutch 41. Shaft 12 (and thus worm 25) is now driven to rotate synchronously with the helical wheels 26a, 26b thus halting further movement of the carriages. The processing of the signals from potentiometers 48, 49 may be such that the investigated surface is planar and to ensure that the received signals are displayed at constant spacing along the spiral scan.

Title: Treatment of alkyl ustilate esters
IPC: C07C51/09
Filed: 1953-04-01
Abstract: The invention comprises alkyl esters of 15-aldehydopentadecanoate and of 2 - hydroxy-15 - aldehydopentadecanoate, and 2 : 15 - dihydroxypentadecanoic acid, its esters and salts when prepared by the following method; and the method of oxidizing 15 : 16-di-hydroxyhexadecanoic acid esters to convert to an aldehyde by means of a glycol-splitting oxidant, followed by reduction of the product to the 15-hydroxy pentadecanoic esters, or performing the same reactions with 2 : 15 : 16 trihydroxyhexadecanoic acid esters, alone or mixed with the above esters.  In examples, methyl 15 : 16 dihydroxyhexadecanoic ester is oxidized with lead tetra-acetate in acetic acid to give methyl 15-aldehydopentadecanoate, which on reduction with Raney nickel gives 15-hydroxypentadecanoic ester from which the acid is obtained by hydrolysis; a crude mixture of the above methyl ester and methyl 2 : 15 : 16-trihydroxy hexadecanoate, known as methyl ustilate mixture, gives by a similar oxidation reduction the two products methyl 2 : 15-dihydroxypentadecanoate (2 - hydroxy - 15 - aldehydo - pentadecanoate being formed intermediately) and 15-hydroxypentadecanoate, the latter of which is hydrolysed to the acid; the 2 : 15 : 16-trihydroxyhexadecanoic methyl ester similarly gives, after reduction, 2 : 15-dihydroxypentadecanoic ester and acid; the ustilic acid methyl ester mixture is also oxidized with Pb3O4 and sodium bismuthate, followed by reduction, to give the same mixture of products as above, and hydrolysis to the acid as above described, if desired.  The known 15-hydroxy-compound may be used to produce the synthetic musk, 15-pentadecanolactone.

Title: Improvements in and relating to the treatment of oil or fat-containing material for the recovery of oil or fat therefrom
IPC: C11B13/00
Filed: 1940-05-23
Abstract: 543,424. Extracting fat from waste vegetable or animal products. SILBERSTEIN, V., KERNOT, J. C., and ATTARI, H. May 23, 1940, No. 9142. Drawings to Specification. [Class 91] Oil or fat is extracted from waste vegetable or animal materials such as waste meat and butcher's offal, kitchen and camp refuse, starch used in the manufacture of granular suet, filtering earths and de-colourizing charcoal which have been used in the purification of oils and fats, by treating the material at atmospheric pressure and elevated temperature not substantially exceeding 100‹ C. with an aqueous solution of a surface tension lowering medium in a container which is subjected to rotary, oscillating or other form of motion. After the removal of the oil or fat the container is agitated to expel excess water from the protein residue. The operation is preferably conducted in an apparatus which resembles a centrifuge enclosed in a relatively deep vessel, which serves to contain the aqueous solution of the surface tension reducing agent. Suitable agents mentioned include froth or foam forming agents, emulsifying agents, alkalies such as caustic soda or sodium carbonate but not including ammonia, organic compounds such as alcohol, phenol, salts of phenolsulphonic acids, also benzene and naphthalene sulphonic acids. A preferred form of the invention is to pass superheated steam through the raw material in the container before subjecting it to the aqueous medium. The aqueous medium is then admitted and maintained at or about boiling point for half an hour. The aqueous and fatty matters are withdrawn and the container rotated to expel the last traces of moisture. The remaining protein material serves as a feeding stock for animals, or as a fertilizer. A suitable apparatus for carrying out the invention is described. Specification 468,061 is referred to.

Title: Improvements in electrical connectors
Inventor: STILLMAKER RICHARD BARNARD
IPC: G01K7/02
Filed: 1966-03-02
Abstract: 1,091,626. Two-part couplings. GENERAL ELECTRIC CO. March 2, 1966, No. 9251/66. Heading H2E. Each connector of a two-part coupling for making connections to a thermocouple comprises a hollow casing 14, 46, an insert member 15, 47 removably insertable in the casing, a pair of contact members 21 and 22, 60 and 61, mounted on the insert by pins 19 and 20, 50 and 51, and resilient members 23 and 24, 54 and 55. To assemble the connector, e.g. the socket connector the contacts are first mounted on the insert and the cable 10 is passed through an aperture 17 in the rear of the casing, the bared ends of each of the leads then being inserted between one of the resilient members and the adjacent contact. The insert member is then pulled back into the casing, the contacts pivoting on the pins against the action of the resilient members to trap the bared leads firmly between them and the contacts. The contacts have projections 25 and 26 which snap behind shoulders 27 and 28 of the outer easing to hold the contacts and the insert in the casing. The contacts are formed with extensions 29 and 30 which when pressed together lift the projections from the shoulders and enable the insert to be removed. The contacts of the socket connector are formed with a half-round groove (Fig. 4, not shown), in which the pins of the plug connector slide, the pins being biased into the groove in one ease by spring 76 which is attached to the side of socket contact 22 and pushes against the casing, and in the other case by spring 74 which engages a circumferential groove 75 in pin 60 which also acts to hold the coupled parts of the connector together. Undue bending of the lead is prevented by a round-ended screw which clamps the cable insulations (Fig. 5, not shown). In a modification, the leads are clamped to the contacts by a rubber member secured to the insert, having the outline of a butterfly. When the insert is located in the casing the rubber member is compressed to hold the leads against the contacts.
