Title: Hose pipes and methods of manufacturing them
IPC: F16L9/02
Filed: 1941-12-01
Abstract: 553,077. Hose pipes and connections. NEUMANN, L. Dec. 1, 1941, No. 15427. [Classes 99 (i) and 99 (ii)] Hose pipes are made from lengths of material capable of being sewn, the edges of the material being turned up hooked into one another, and stitched together. Fig. 1 indicates one form in which the edges of the strip 1 are turned up at 2<SP>4</SP> and 2<SP>5</SP>, the turned-up parts being hooked together and secured by rows of stitching 3. The seam may be strengthened by an additional strip, and the hose may be reinforced by an inner or outer layer of wire gauze or netting, or a helical spring. Angle, T, or cross-shaped hose connections may be made from two pieces of material cut to the appropriate shape and turned up and secured around the edges in a similar manner. The material may be rendered impermeable by layers of rubber, tar, fatty pastes, &c. or by impregnating with a stiffening liquid, such as resins or gums insoluble in water. In making hoses for irrigation, the material, before being sewn up, is formed with holes, which are fitted with metal rings or the like for fixing the irrigation nozzles.

Title: Apparatus for testing tampon cords
Inventor: GLASBY FRANCIS GOFF
IPC: G01M99/00
Filed: 1965-04-12
Abstract: 1,126,964. Testing cords. ROBINSON & SONS Ltd. April 7, 1966 [April 12, 1965], No. 15445/65. Heading G1S. Apparatus for testing tampon cords comprises automatically operable means 23, 25 for gripping a tampon cord 22, means 39 for restraining the tampon against movement as its cord is gripped, means for producing tension between the gripped cord and the tampon pellet and means for indicating either the absence of a tampon cord, breakage of a cord or detachment of a cord from the tampon pellet. The tampons 28 are fed periodically on a conveyer 14 Fig. 2 (not shown), to the testing station where air jets are applied to cause the tampon cord 22 to assume a vertical attitude. Rotation of a cam 32 causes the rod 37 to slide so that the tampon pellet is held in position by tip 39. With the tampon held in this position a cam 26 on shaft 16 causes the opening of a valve 27 which applies pressure to the rod 41 which presses the tampon cord against the plate 25. Further rotation of the shaft 16 causes the gripper assembly to move downwards under the bias of spring 48, the tension of which can be adjusted by screw 49. Should the tampon cord break or become detached from the tampon pellet or should there be no cord present the plate 47 will continue to move downwards and will strike a plunger 50 Fig. 2 (not shown) of a switch 51 to stop the machine or to signal the fault. Further rotation of the cams causes the plate 42 and arm 37 to move to their initial positions and valve 27 is closed.

Abstract: The invention comprises: (1) a process for the preparation of steroids of the formula <FORM:0871874/IV (b)/1> (wherein R is hydrogen, alkyl or aryl and R1 is alkyl or aryl) which comprises oxidizing a steroid of the formula <FORM:0871874/IV (b)/2> with an organic per-acid to form the corresponding 5a ,6a -epoxide, reacting this with a methyl magnesium halide to give the corresponding 6b -methyl-3b ,5a -diol, oxidizing this to form the corresponding 3-ketone, and dehydrating and epimerizing this by treatment with a source of hydrogen ions; and (2) the specific steroids 3b ,5a -dihydroxy-16a ,17a -(21,21-dimethyl - 41,51 - dioxolane) - 6b  - methyl - pregnan-20-one, 3b ,5a -dihydroxy-16a ,17a -(21-phenyl-41, 51-dioxolane)-pregnan-20-one and 16a ,17a  - (21,21 - dimethyl - 41,51 - dioxolane) - 5a  - hydroxy - 6b  - methylpregnan - 3,20 - dione. Preferred organic per-acids are peracetic, perbenzoic and monoperphthalic and the oxidation is desirably effected with chromium trioxide in acetic acid or with chromic acid in pyridine.  The 3b -hydroxy group of the 5a ,6a -epoxide may, if desired, be acylated prior to reaction with the methyl magnesium halide, to increase the solubility of the epoxide in the solvent for the Grignard reaction. The dehydration and epimerization is preferably effected in one operation with a source of hydrogen ions, e.g. hydrochloric acid, in a lower aliphatic alcohol, but reference is also made to dehydration with, for example, a very dilute solution of an alkali metal hydroxide and subsequent epimerization by known methods.  Examples are given.  16a ,17a  - (21,21 - R.R1 - 41,51 - dioxolane) - 3b -hydroxypregn-5-en-20-one starting materials of the second general formula above are prepared by condensing 3b ,16a ,17a -trihydroxypregn-5-en-20-ones with appropriate aldehydes or ketones, desirably in presence of an acid catalyst.

Abstract: 1409333 Cathode-ray tube circuits; sawtooth wave generators ROBERT BOSCH FERNSEHANLAGEN GmbH 4 April 1973 [7 April 1972] 16138/73 Headings H3T and H4T In a television system in which a television camera tube together with its deflection coil system is remotely positioned with respect to the associated deflection generator the horizontal deflection coil(s) are connected to the generator by a pair of conductors each of which includes a winding, the two windings being bifilar wound and provided with an adjustable core for horizontal size (raster width) adjustment and one of the conductors additionally including an adjustable resistance for horizontal linearity adjustment. Thus, as shown in Fig. 1, the horizontal deflection coils 2, 3, 4 of a colour television camera 1 are connected via respective pairs of conductors 6, 7; 8, 9; 10, 11, to a remote "electronics pack" 12 containing, inter-alia the deflection generator 13, the pairs of conductors being connected to the latter via respective bifilar wound coil pairs 22, 23, 24 (see also Fig. 2), provided with adjustable cores 26, 27, 28, one of the conductors of each pair including a respective adjustable resistor 29, 30, 31 and additionally a fixed value resistor 32, 33, 34 each of which may be short-circuited by respective mechanically coupled switch means 35, 36, 37. The cable containing the conductors 6 to 11 may be of one length, e.g. one metre, when the camera operator also carries the electronics pack 12, e.g. on his back, in which case switches 35-37 are left open. If however the electronics pack is at a greater distance from the camera casing 1, a length of about 15 metres may be employed for the cable and in this case compensation for the increased resistance, to prevent changes in the linearity adjustment set by adjustable resistors 29-31, is effected by closing switches 35-37 to short circuit the resistors 32-34. The invention is concerned with a television "news reel" camera in which, for convenience of handling, the camera casing 1 contains the minimum of components, all other components including picture signal processing circuitry being accommodated in the "electronics pack" 12.

Abstract: 713,262. Balls for games. TUCK & CO., Ltd. July. 8, 1952 [July 9, 1951], No, 16216/51. Class 132(2) [Also in Group V] A football bladder is formed by cutting suitably shaped panels 7 ... 10 from superposed sheets of raw rubber or the like so that the panels adhere together along adjacent edges, applying a slight air pressure between the panels to cause each joint to close book-wise so that the ends of the panels abut and then curing this embryonic bladder 1 in a cavity mould maintained hot before the insertion of the bladder and during the curing. The bladder may be made of two panels only. An aperture 11 is formed in the embryonic bladder 1 preferably at the junction point of the panels and a spear-shaped air nozzle 12 carrying a tube 2 of raw rubber or the like which ultimately forms an internal valve-seating member, is inserted in the aperture prior to the initial inflation effected through the nozzle. The embryonic bladder is cured in a two-part mould 13, 14 having steamheated jackets 18 joined by a flexible pipe 20. The nozzle 12 has a part 21 which fits detachably in a socket formed in the lower mould part 13 so that the bore of the nozzle is aligned with an air-pressure pipe 23. The upper mould part 14 is hinged to the lower part at 15 and is fitted with a counterweight 17 and the mould parts are held closed by three toggle linkages 26. When the mould is closed a valve 25 in pipe 23 is opened to admit pressure air through nozzle 12 to force the bladder against the mould walls. Upstream of the valve 25 are three valves 27 each associated with one of the linkages 26 in such a way that pressure air cannot be supplied to the bladder until the mould is properly closed.
