Title: Fluidic gauge sensor head
IPC: B65H63/06
Filed: 1973-02-14
Abstract: 1374062 Fluidic gauges GENERAL ELECTRICCO 14 Feb 1973 [15 Feb 1972] 7231/73 Heading G1M A fluidic gauge comprises a base 11 having a passage 28 connectable to a source of fluid and a gauge plate 32 resiliently biased against the base by a spring 40, a groove 33 in the plate 32 being in communication with the passage 28. The plate is loosely retained between the base and a support 31 by a pin 44, the base and the support having interengaging grooves and projections such that the support can be slidably received in the base until it engages a stop 46. In use, material such as a yarn or wire is fed through the groove 33 and restricts the flow of fluid therethrough to an extent depending on the cross-sectional area of the material, the back pressure on a line connected to passage 28 thus being a measure of the cross-sectional.area of the material. Owing to the resilient mounting of the gauge plate 32 any flaws in the material can pass through the gauge without damage to the gauge or to the material.

Title: Improvements in and relating to the dehydration of organic liquids
IPC: C07C29/82
Filed: 1930-03-06
Abstract: <PICT:0350473/III/1> In a continuous process for obtaining dehydrated organic liquids e.g. alcohol, propyl alcohol, glycol chlorhydrin, by a combination of ordinary distillation and azeotropic methods, the organic liquid is withdrawn, at a concentration greater than that of an azeotropic mixture of the liquid and water, from a point situated between that part of the apparatus where concentration takes place and that part where the azeotropic mixture is treated. A steam-heated distillation column 1 having the usual extraction zone I and concentration zone II is provided at the top with additional plates forming an azeotropic distillation zone III in which an entrainer liquid acts indefinitely.  Wort to be concentrated is supplied through a pipe 16 and heat-changer 17 where it is preheated by the exhausted vinasses drawn off through a pipe 18.  The alcoholic vapours rising in the column cause the entrainer liquid e.g. a mixture of petrol and benzene placed in the zone III to boil and the vapours evolved are condensed in a condenser 4 and the condensate separated into two layers the upper layer being returned to the zone III by a pipe 7 and the lower layer through a pipe 8 to the zone II. Concentrated alcohol mixed with entrainer liquid is drawn off by a pipe 9 from a plate between the zones II and III and is delivered to a small column 10 partly heated by steam and partly by alcoholic vapours circulated from the zone II through an exchanger II by pipes 13, 13a, the anhydrous alcohol being drawn off through a pipe 14.  An auxiliary condenser 3 is provided to relieve the condenser 4 the condensate being separated into layers which are returned through pipes 5, 6.  Entrainer liquid vapourized in the column 10 is condensed and returned through a pipe 15.  Specifications 243,368, 253,128, and 289,051, [all in Class 32, Distilling &c.], are referred to.

Title: Manufacture of oxyaldehydes of the cyclopentanopolyhydrophenanthrene series or esters thereof
IPC: C07J75/00
Filed: 1941-06-13
Abstract: 551,402. Cyclopentanophenanthrene oxyaldehydes. REICHSTEIN, T. June 13, 1941, No. 7489. Convention date, June 17, 1940. [Class 2 (iii)] Oxyaldehydes of the cyclopentanopolyhydrophenanthrene series are prepared from a compound of this series which has in the 17-position a side chain of the form -<SP>3</SP>CH(OH)-<SP>2</SP>CH(OH)-<SP>1</SP>OH  2 (OH) by a process which comprises heating the compound in the presence of a ketone and a dehydrating agent to form a ketonide with hydroxyl groups 1 and 2, esterifying hydroxyl group 3, liberating groups 1 and 2 by treatment with an acid agent and the glycol so produced converted into an aldehyde in known manner by treatment with for example lead tetracetate or periodic acids. If desired the esterified hydroxyl group 3 may be finally hydrolysed. Carbonyl. compounds mentioned as suitable for use in the first stage of the process include acetone, methyl ethyl ketone, cyclohexanone or benzaldehyde, while the preferred dehydrating agent is an anhydrous inorganic salt such as copper sulphate, sodium sulphate or zinc chloride. Hydroxyl group 3 may be esterified with for instance the residues of an aliphatic hydroaromatic or aromatic carboxylic or sulphonic acid such as formic, acetic, propionic, butyric, benzoic, or toluene sulphonic acid. Acid agents suitable for splitting off the carbonyl group include an organic or inorganic acid such as acetic, sulphuric or a hydrohalogen acid. In an example 17-trioxy-propyl testosterone is heated with acetone in the presence of anhydrous copper sulphate to obtain an acetone derivative which is then esterified on hydroxyl group 3 by acetic anhydride in the presence of pyridine. The acetylated acetone compound is deconiposed. by glacial acetic acid to give the trioxypropyl-30-monoacetate compound which is then treated with periodic acid to form # <SP>4</SP> -pregnene- 3-one-17 : 20-diol-21-al-20-monoacetate. This compound has a similar action to certain of the cuprarenal cortical hormones. The Specification as open to inspection under Sect. 91 includes also the use of starting materials of the general formula - <SP>3</SP>CH(OH). <SP>2</SP>CH(OH)-<SP>1</SP>CH(OH)-R where R denotes a hydrocarbon radical. This subject-matter does not appear in the Specification as accepted.

IPC: F42C15/30
Filed: 1954-03-15
Abstract: 770,953. Aerial warfare. REDWING, Ltd. May 13, 1955 [March 15, 1954], No. 7518/54. Class 9 (2). A torpedo or other explosive device adapted to be launched from aircraft is provided with an arming unit comprising a body with an extension 2 screw-threaded to receive a housing 3 for a container 4 filled with gas under pressure. When the housing is fully screwed on, a hollow needle 7 punctures the container 4 so that the gas escapes into a recess 9 in a member 10 which clamps a diaphragm 12 against the inner wall of the extension 2. Over the port 11, the diaphragm is supported by a rod 13 extending from a piston 14, the piston being held by a lever 16, which is locked by a pin 17 and a safety pin 19. To arm the torpedo, the safety pin is withdrawn by hand, so that when the torpedo is launched the pin 17 is withdrawn and the lever 16 releases the rod 13. The gas pressure then ruptures the diaphragm and the gas passes through a passage 20 and displaces a piston valve 22, the movement of the valve being controlled by an adjustable needle valve 26. On displacement of the valve 22 a passage 23 is uncovered and the gas passes through a conduit 25 and flexible tube 27 to displace a piston 29 having an end 30 adapted to be connected to mechanism which arms the detonator of the torpedo. Specification 756,023 [Group XXVIII] is referred to.

Title: Semiconductor transducers
IPC: H01L21/00
Filed: 1964-02-24
Abstract: 1,045,934. Semi-conductor strain transducers. RAYTHEON CO. Feb. 24, 1964 [March 28, 1963], No. 7628/64. Heading H1K. A strain transducer comprises a semi-conductor body having a P-N junction formed therein and supported in one region by a support member, and means for causing in a small volume of the junction a stress which is relatively large compared with the stress in the remainder of the body when a force setting up a bending moment in the body is applied to a further region of the body. The means may be a stylus bearing against the body or an incision made in the body to a depth close to but not reaching the junction. A wafer 10 (Fig. 1, not shown) of germanium or silicon having a P-N junction 11 is held by electrodes 16, 17 so that a surface 13 of the body is in contact with a fixed stylus 14. Application of force to the free end of the body in the direction of arrow 19 or 20 causes a variation in the pressure applied by the stylus and consequently a variation in the relatively large stress in the localized area of the junction adjacent the stylus. The electrodes may consist of copper, lead or tin, and may be of annular form to support the periphery of a circular semi-conductor body. The stylus may be omitted and an incision made in the body to a depth close to but not reaching the junction, so that when the bending moment is set up a relatively large stress is created in the area of the junction adjacent the incision. In a modification (Fig. 4, not shown) the semi-conductor body 40 contains two P-N junctions 41, 42 near its opposite surfaces, and two incisions are made, each extending from one surface to a depth close to, but not reaching, the junction furthest from that surface. A third electrode 45 is provided on the upper surface 46 of the body. The incisions may be replaced by two styli in contact with the surfaces.
