Title: Improvements in or relating to apparatus for supporting a stack of gramophone records and for releasing the lowermost record when the preceding record has been played
IPC: G11B17/16
Filed: 1949-07-23
Abstract: 668,097. Magazine gramophones. DAWSON, T. C. W. July 23, 1949. No. 19454/49. Class 40 (ii). Apparatus for supporting a stack of gramo-. phone records and for releasing the lowermost record when the preceding record has been played, comprises a hollow spindle 1, Fig. 2, on which the records are stacked, the chamfered lower end of which is removably inserted in the turntable spindle, not shown, and held by releasable spring catches engaging recesses 26. Aplunger 12 biassed downwardly by a spring 20 is slotted at its upper end to give clearance to a pin 9 extending across spindle 1 on which is pivoted a record supporting finger 10 carrying a pin 16 engaged in a gap in plunger 12. The right hand one of the diametral slots through which finger 10 extends is formed as a keyhole slot, the circular top part of which just retains a ball 11 which coacts with a fixed cam surface 3. The opposite half of the spindle 1 is cut away to leave a record supporting shelf 5. In the position shown, a stack of records threaded on spindle 1 is supported on the projecting ends of finger 10. If now plunger 12 is raised, for example by the mechanism described in Specification 668,098, finger 10 is rotated anticlockwise through pin 16 to the upright position to release the lowermost record: At the same time the ball 11 is forced upwards against surface 3 to project through the keyhole slot, thus forcing the next record to the right so as to be over shelf 5. Plunger 12 is thus released to return finger 10 to the position shown, when the remaining records slide off shelf 5 onto finger 10. In a modification, Figs. 13, 14 (not shown), the cam surface 3 is replaced by a second ball resting against a horizontal surface. In a further modification, Fig. 11, the balls are replaced by a member 41 pivoted at 40 and having a' part 42 engaging a recess in the finger 10. When plunger 12 is raised, finger 10 is rotated clockwise through a right angle to release the lowermost record. At the same time member 41 is rotated anticlockwise to move the next record B to the right so as to rest on shelf 5. The parts are then restored to the position shown, and the stack moves down from shelf 5 on to finger 10. In a final modification, Fig. 15, when plunger 61 moves upwards to rotate finger 10 to release the lowermost record, a slide 69 is moved up causing a pin 70 to engage a cam surface 71 to rotate a lever 67 about a pivot 66 causing a nose 68 to push the next lowest records to the right to be temporarily supported on shelf 5. To remove the records after playing, the spindle 1 is withdrawn from the turntable spindle.

Title: Method of and apparatus for sealing a casing in a bore hole
Inventor: ZANDMER SOLIS MYRON
IPC: E21B33/14
Filed: 1953-07-14
Abstract: 728,197. Wells. ZANDMER, S. M. July 14, 1953, No. 19591/53. Class 85. A method of sealing a casing in a borehole traversing a porous producing stratum comprises the steps of lowering a casing into the borehole, moving duct-forming devices laterally from the casing into engagement with the stratum, forcing fluid sealing material downwardly through the casing and then upwardly between the casing and the wall of the bore hole and around the duct-forming devices, and after the sealing material has set, opening a passage through the duct forming devices to provide communication between the interior of the casing and the porous stratum. As shown, a casing 12 is positioned in a bore hole so that an annular space exists for filling by a sealing material 13. Opposite oil or gas-producing strata 14 the casing 12 is provided with ductforming devices 15. Each device comprises a bushing 16 screwed into a hole in the casing 12, the bushing being provided with a closure 18 formed with an orifice for a spring-pressed valve 20. Within the bushing is a sleeve 24 in two parts 26, 27 press-fitted together, the part 27 having a shoulder 28 by means of which in association with shear pins 45 the sleeve is prevented from being moved outwardly while the pins are unbroken. The part 26 is provided with a gasket 32 of resilient material. The interior of the sleeve is filled with a perforated disc 46 and with material 44 which is readily dissolvable in acid or chemical used for treating the strata 14. The disc 46, the closure 18, and the part 27 of the sleeve 24 are made of metal or alloy also readily dissolvable in the acid or chemical. The casing 12 with the duct-forming devices attached, is lowered into the bore hole and fluid under pressure is pumped past the ball valve. When the pressure is sufficient the shear pins 45 break and the sleeve 24 is pressed against the wall of the bore. By the provision of balls 34 resiliently pressed against a ramp 33, backward movement of the sleeve is prevented. Sealing material under greater pressure is then supplied to the casing, the pressure eventually forcing downwardly a closure 41 to uncover ports 42 through which the sealing material passes to the annular space around the casing 12. When the sealing material has set, strata-treating acid or chemical for example hydrochloric acid is pumped into the casing, the acid dissolving the closure 18, sleeve part 27, disc 46 and material 44, to open a passage to the stratum. A modified form of duct-forming device is described in which the sleeve is in one piece wholly dissolvable to the acid or chemical.

Title: Multi-cylinder supercharged internal combustion engines
IPC: F02B33/44
Filed: 1961-06-01
Abstract: 941,220. Charging two-stroke and four-stroke engines; valves. SULZER FRERES S.A. June 1, 1961 [June 15, 1960], No. 19867/61. Heading FIB. In a method of operating a multi-cylinder engine supercharged by exhaust-gas turbosuperchargers and having cylinders arranged in at least two groups which have a common scavenging or charging air receiver and each have their own exhaust-gas turbine driving a supercharger each supercharger being in parallel with or followed by at least one engine driven auxiliary pump, in the event of a breakdown,of one of the turbosuperchargers different groups are operated at different power outputs by reducing the fuel charge of the affected group to suit the capacity of its auxiliary pump or pumps and isolating this group by partitioning the air receiver so that it receives air only from its auxiliary pump or pumps, thereby allowing the remaining cylinders to continue to operate at their full mean effective pressure. The term "auxiliary pump" includes the underside of the piston when used for aiding scavenging, or a separate blower or pump for scavenging in the case of a two-stroke engine or for changing the air charge in the case of a four-stroke engine. During normal operation of the two-stroke engine shown in Fig. 1 plates 17 and 18 are omitted and all openings 12 are sealed, so that the two turbosuperchargers 4 operate in parallel to supply compressed air, cooled in coolers 7, into a common receiver 8. The air passes from the receiver 8 through non-return valves 9 into separate scavenging chambers 10a, Fig. 2, interconnected with chambers 10 where it is further compressed by the undersides of the pistons and passes through scavenging ports 21 to the combustion chambers. The combustion products pass through conduits 11, past rotary exhaust control valves 22, to operate the turbines 5. If one of the turbosuperchargers fails covers 14 are removed from that part of the receiver 8 associated with the faulty turbosupercharger, and this part of the receiver is isolated from the other part by inserting plates 17, 18 as shown in Fig. 1. The undersides of the pistons of the group associated with the defective turbosupercharger draw in air through the openings 12 to provide limited scavenging of their cylinders, thereby allowing this group to operate at a reduced power output whereas the other group produces normal power. The fuel charge of the low power group is reduced according to the capacity of the auxiliary pump as by modifying the fuel linkage mechanism by inserting pivot pins in holes provided for that purpose. Specification 815,387 is referred to.
Patent GB-672726-A (GB)
Title: Antibiotics and the production thereof
Filed: 1949-07-29
Abstract: Antibiotic substances are manufactured by bringing together and cultivating a mould culture and a bacterial culture, the mould being such that it will generate a substance which is antibiotically active against the bacteria, adjusting the temperature of incubation to permit of simultaneous culture of the mould and the bacteria and to favour the growth of the mould, filtering the liquid medium and extracting the antibiotic substance from the filtrate (e.g. by precipitation with alcohol or acetone or by adsorption).  The mould may be one which spontaneously generates an antibiotic substance while growing alone (the amount generated being enhanced by the present process), but it is also possible to use the process to render moulds antibiotic which had previously little or no activity against certain bacteria.  The process may be carried out by surface or depth culture, the bacterial culture in the former case being advantageously cultivated to the stage at which it forms a goffered velum on the surface of the liquid, and spores of the mould then being re-inseminated on the surface of the velum, preferably after replacing part (e.g. half) of the culture medium by a culture medium for the mould.  Preferably, after a period of simultaneous cultivation, spores of the mould are re-inseminated on a second similar velum, this process being if desired repeated one or more further times with increase of antibiotic activity at each transference, the antibiotic substance being extracted from the liquid from the vessel in which the last re-insemination has occurred.  Alternatively, the mould culture is prepared first and a part of the culture medium is then replaced by a bacterial culture. Examples describe the surface and depth culture of Aspergillus flavus or A. oryzae in the presence of tubercle bacilli, the preferred temperatures being 37 DEG  C. during the cultivation of the bacilli and 30 DEG  C. for the combined cultivation.  The tubercle bacilli may be replaced by coli bacilli, in which case depth culture is preferable.  Other moulds specified are A. ustus, A. niger, A. nidulans, A. glaucus, A. Amstelodami, A. effusus, A. parasiticus, Penicillium chrysogenum, P. glaucum, Actinomyces griseus, Rhizopus oryzae and R. nigricans.
