Title: Couplings for pipes
Inventor: JACKSON JOSEPH CHARLES
IPC: F16L17/035
Filed: 1970-01-28
Abstract: 1301028 Pipe couplings; joint-making packing CERTAIN-TEED PRODUCTS CORP 28 Jan 1970 [28 Jan 1969] 4160/70 Headings F2B and F2G A coupling sleeve 6 has internal grooves near its ends for sealing rings 9 having recesses 10 and axially spaced, internal tapered portions 13, the tapers converging from the ends of the sleeve to the middle thereof. The bore of the sleeve 6 is greater than the outer diameter of the pipes 3, 4 to be inserted, whereas the inner diameters of the tapered portions 13 are less, so that the pipe ends abut the tapered portions. The ends of the pipes and sleeve are tapered to facilitate insertion of the pipes and the sleeve accommodates axial pipe expansion by slight radial expansion, allowing the pipe ends to move along the tapered portions 13. The pipes are of polyvinyl chloride and the sleeve 6 is formed of the same, or a similar resin having the same coefficient of thermal expansion. The sealing rings 9 are of natural or synthetic rubber, e.g. polyvinyl chloride or nitrile butadiene and are provided with recesses 10 to accommodate distortion of the ring upon insertion of pipes 3, 4 therein.

Title: Improvements in or relating to the production of benzene hexachloride
IPC: C07C17/386
Filed: 1946-02-11
Abstract: Benzene hexachloride, in non-coherent granular form and with diminished odour and suitable for including in pest control compositions, is obtained from a benzene solution of crude benzene hexachloride by steam distillation to remove benzene, continuing the steam distillation for a further period of at least one hour after removal of the benzene, preferably accompanied by agitation of the mixture, and pouring the resultant crude benzene hexachloride in the form of a mobile slurry or melt into water at a temperature between 30 DEG  C. and 60 DEG  C.  The benzene hexachloride starting-material may advantageously contain an enhanced proportion of the gamma isomer, as prepared by the methods of Specifications 573,693, 586,439 and 586,442.  In examples: (1) a solution of benzene hexachloride in benzene prepared by chlorinating benzene in the presence of actinic radiation and containing substantially 20 per cent by weight of benzene hexachloride is steam distilled to remove unchanged benzene, the steam distillation is continued for a further period accompanied by agitation.  The deodorised benzene hexachloride is then dried at room temperature.  (2) A melt of benzene hexachloride prepared as in example (1) is allowed to fall from a dropping vessel into a vessel of water at 50 DEG  C. and agitated by a rapid stream of air. Specifications 573,689 and 592,677 also are referred to.

Title: Electromagentic drive for contacts opening and closing rhythmatically, particularly for electric current converters with mechanical contacts
IPC: H02M1/26
Filed: 1946-02-13
Abstract: 627,214. Converting ; reciprocating motors. AKT.-GES. BROWN, BOVERI, & CIE. Feb. 13, 1946, No. 4562. Convention date, Feb. 20, 1945: [Classes 35 and 38 (ii)] The contacts 5 of an interrupter, particularly for rectifying an alternating current, are operated against an opposing force, such as that of a spring 6, by the armature 7 of a magnetic system of which the stationary part has two pairs of poles 12a, 12b with A.C. windings 13, 13a encircling the yoke between the poles of each part and a D.C. polarizing winding 15 between the pairs of poles. The polarizing flux passing through the armature between the two pairs of poles is caused by the A.C. to oscillate between the two poles of a pair and the armature is constrained to oscillate without changing the air gap. An additional polarizing winding 9 may encircle the armature. (The Figure shows only one half of each coil.) Control of the rectified current or voltage may be obtained by varying the phase relation between the potentials applied respectively to the rectifying contacts and to the A.C. driving windings and by varying the amplitude of the A.C. current in these windings. Direct current control coils 14, 14a may be added between each pair of poles, whereby the mean displacement of the armature may be varied. All controls may be simultaneously varied, and like control windings of several interrupters may be associated in the same circuit as indicated in the three-phase rectifier in Fig. 3 (not shown), and these circuits may be automatically controlled in dependence on the load or voltage of the. converter as described in the Specification.

The casing pivots about a pin 15 passing through the spindle and through a pair of plates 16 carrying a lug 9, the lower end of which is shaped similarly to the serrations. The spindle supports a radially extending bar 18 between the outer end of which and the casing a spring 19 is located. To adjust the spindle, the knob 14 is depressed and rotated and, when released, the casing is returned by the energized spring to cause the lug 9 to engage accurately in its new serration. The ring 10 may rotate with the handle and engage a fixed lug, and the casing may be raised to release the lug 9.

Abstract: 1334198 Hydraulic reciprocating motors H MOLLY 1 Feb 1972 [4 Feb 1971] 4633/72 Heading F1A [Also in Division F2] A hydrostatic transmission comprises a variable displacement motor 44 whose cylinder block 48 is pivotable about an axis 52, eccentric to the axis of the output shaft 40, the motor being supplied by a pump 30 driven by input shaft 14, which shaft also drives a cycloid make up pump 20. The pump 30 is variable in its displacement, but is intended to run at maximum displacement during operation with the motor being varied. As shown the motor comprises swash plate 42, piston rods 74 with pistons 54, a stationary valve portion 76 of a pivotable frame 50 and a hollow trunnion 82 which guides the cylinder block, the pump design being similar. A cylinder 46 (one of two) encloses a differential piston which adjusts motor displacement and holds the cylinder block 48 against the torque produced by the rod pressure. In a further embodiment the pump feeds two sets of two motors Fig. 12 (not shown), the pump being reversible and the circuit including a valve to control pressure to the adjusting cylinders. One set of two motors is shown in Fig. 13 wherein each motor 130, 132 has its cylinder block (e.g. 146) pivotable about an off-axis point, the outputs of the motors being half shafts 176, 177 geared to the swash plates 140, 141, the cylinder blocks being drivingly attached to the swash plates through bevel teeth (e.g. 156, 158) on toroids permitting the cylinder blocks to be pivoted. The trunnions on which the pivotable frames (e.g. 150) are mounted contain the passages for oil supply to the motors, and motor capacity is adjusted by cylinders 134 and 136. The maximum capacity of the (or each) motor at maximum displacement in each embodiment is a multiple of that of the pump.
