Title: The manufacture of new hydrogenated dioxydiphenylmethane compounds
IPC: C07C35/14
Filed: 1925-09-09
Abstract: 252,594. Chemische Fabrik auf Actien (vorm. E. Schering), and Jordan, H. Sept. 9, 1925. Hydrogenated dioxydiphenylmethane compounds are obtained by treating the condensation product of a phenol and a ketone with hydrogen in the presence of a catalyst until either six or twelve atoms of hydrogen have entered into combination. The products are useful for therapeutic and other purposes. The preparation of the following compounds is described : - 4-oxycyclohexanyl-p-oxyphenyl-dimethylmethane from p-dioxydiphenyldimethylmethane, 4-oxy-3-methylcyclohexanyl-4-oxy-3- methylphenyl-dimethylmethane from 4-dioxy-3- dimethyldiphenyldimethylmethane, di-4-oxycyclohexanyl-dimethylmethane from p-dioxydiphenyldimethylmethane, di-4-oxy-3-methylcyclohexanyl-dimethylmethane from 4-dioxy-3-dimethyldiphenyldimethylmethane, and dioxycyclohexanyl-methylethylmethane from the condensation product of methylethylketone with phenol. Some of the products are mixtures of stereo-isomers.

Title: Improvements in or relating to pipe joints
IPC: F16L19/10
Filed: 1924-09-24
Abstract: 241,689. Fyffe, T. L., and Fyffe & Co., Ltd. Sept. 24, 1924. Joints with longitudinal pressure and with yielding outer part compressed. -A keyed fluid-tight joint between a copper, brass, gun-metal or other " softmetal " pipe and a socket constituted e.g. by a union for connecting the pipe to a second pipe, or by a tap or similar tubular body or by a closure such as a blind flange comprises a packing-ring, 9 of copper, brass &c. somewhat harder than the metal of the pipe, and means for compressing the ring longitudinally and forcing one or both of its edges into the metal of the pipe to form a keyed connection. The end faces of the packing-ring are bevelled and are either flat or spherically curved, and the clamping faces 11, 12 are also bevelled, but at a more obtuse angle, so that the pressure is applied at the extreme margins only of the packing-ring. Grooves mav be provided in the outer surface of the ring and serrations or screw-threads on the inner surface. When two pipes are to be connected the joint may be as shown in the figure or the packing-ring may be arranged to span the actual butt-joint between the two pipes, the socket then being constituted by one of the clamping- members. Specifications 29811/09 and 196,627 are referred to.

Title: Improvements in or relating to a device for registering sound vibrations in records with the aid of a pick-up
IPC: G11B3/08
Filed: 1931-08-10
Abstract: 392,511. Gramophones. NAAMLOOZE VENNOOTSCHAP PHILIPS' GLOEILAMPENFABRIEKEN, 13D, Emmasingel, Eindhoven, Holland. Aug., 10, 1931, No. 22630. Convention date, Aug. 15, 1930. Void [Published under Sect. 91 of the Acts]. [Class 40 (ii).] Records can be made on a gramophone by means of a pick-up influenced by sound waves or electromagnetically from a microphone or a wireless receiver by supporting the blank from the turntable on a member provided with a spiral groove for traversing the pick-up which is detachably connected to a pivoted arm. In the Figure, the blank 8 is shown supported on a disc 6 connected by part 4 with a disc 5 having a spiral guide groove, and a projection 7 centres the blank. The pick-up 11 has an arm 12 adjustably secured by screws 14 in a channel member 13 whose end is mounted by pivot 16 to a block 18 pivoted in a frame 19 supported by a vertical pivot 20 in a mounting 21. An arm 10 connected by a pivot 17 to the block 18 carries a pin 9 which tracks the guide groove on the disc 5 to traverse the pick-up over the blank, and a stirrup 27 depending from the end 15 of the channel 13 lifts the arm 10 to disengage the pin 9 when the pick-up is lifted. A block 23 secured to the mounting 21 has a bore 24 to provide an alternative mounting for the pivot 20. The pick-up arm 12 carries a resilient pivoted pin 26 which can be engaged directly with the mounting 21 for reproducing. The discs 5, 6 may be detachably connected and spirally grooved on both surfaces so that a new guide groove surface is presented on reassembly. In a modification, the pair of connected discs may be replaced by a single stepped disc having a spiral guide groove in its inner part and supporting an annular record on its reduced outer part, and the arm carrying the guide pin is mounted to turn on a fixed vertical pivot and has a lateral branch providing a horizontal pivot for the pick-up arm, this pivot connection providing a stop whereby on lifting the guide pin arm from its track the pick-up arm is also lifted.
Patent GB-622192-A (GB)
Title: Improvements in and relating to slip regulators for motor generator sets
IPC: B60L50/30
Filed: 1944-11-16
Abstract: 622,192. Electricity supply; automatic control systems. BRITISH THOMSON-HOUSTON CO., Ltd., PETCH, T. H., and LIDDIARD, H. W. C. Nov. 16, 1944, No. 22659. [Class 38 (iv)] In a motor-generator set having a fly-wheel F rigidly coupled to the shaft of the generator C, an eddy-current slip-coupling between the generator and the motor M is controlled by means responsive to the motor input to maintain the said input constant. The driven half C1 of the coupling has a D.C. field winding CF connected in series with the armature A of a separately-driven amplidyne exciter having one field winding AFM connected through a potentiometer PR to a fixed D.C. source, a second field winding AFC being connected in opposition to winding AFM and energized in accordance with the motor input current through a rectifier R and current transformer T. Thus if the motor input current tends to vary above or below the setting of the current in winding AFM, due to a fluctuation in load on the generator, a resultant flux is produced which causes the amplidyne to buck or boost the current in the winding CF, thereby varying the slip of the coupling and causing the fly-wheel F to impart energy to the generator for an increased load or to absorb energy from the motor for a decreased load. Since the motor input and speed are thereby maintained constant, a synchronous motor may be employed. Hunting may be obviated by the provision of a transformer ST whose primary is connected across the armature A and its secondary connected to a third field winding AFS. If it is desired to prevent the amplidyne boosting the field winding CF appreciably, a fourth field winding AFL may be connected in opposition to winding AFM through a rectifier R1 to the terminals of armature A and so proportioned that when boosting occurs it neutralizes the effect of winding AFM.

Title: Improvements in or relating to the treatment of alcohols produced by the oxo synthesis process
IPC: C07C29/74
Filed: 1950-09-20
Abstract: Impure water-immiscible primary C4-C12 alcohols produced by the Oxo synthesis are purified from sulphur compounds by intimately contacting, without emulsion formation, with an aqueous solution of hypochlorous or hypobromous acid or water-soluble salts thereof, stratifying, and distilling the alcohol layer.  Octanols and nonanols in particular, used in preparing ester plasticizers with, e.g. phthalic, maleic or adipic anhydride, may be treated, and may be topped or distilled prior to treatment.  A subsequent caustic alkali wash may be used, generally followed by a distillation.  The hypohalite solution should be prepared immediately prior to use as by passing chlorine into water or reacting a hypochlorite with acid. Salts such as sodium, potassium or calcium hypochlorite can be prepared from chlorine and the metal hydroxide or by electrolysis of the chloride.  Agitation is necessary during the treatment and an emulsion inhibitor may be added.  Room temperature is satisfactory with times of 2 mins. up to 2 hrs., optionally about 100 mins. About 0.2-1, preferably 0.5 vol. alcohol per vol. of solution is used.  For sodium hypochlorite treatment of C8 alcohol it is preferred to have a weight concentration of alkali of 10-15 per cent and active chlorine equivalent to 0.5-3 g. per 100 ml. of solution.  Examples describe the treatment of crude and finished C8 alcohols with sodium hypochlorite or hypobromite, calcium hypochlorite or hypobromous acid at various concentrations and times of contact.
