Title: Improvements in or relating to automatic apparatus for percussive drills
IPC: E21B44/08
Filed: 1947-10-01
Abstract: 628,433. Percussive drills. CONSOLIDATED PNEUMATIC TOOL CO., Ltd., MACDONALD, N., and STEEL, J. P. Oct. 1, 1947, No. 26494. [Class 124] ' The cradle of a pneumatic percussive drill, having an automatic feed wherein the power is derived from the reaction to the longitudinal pulsations set up by the reversal of the piston, is connected to its support by clamping mechanism responsive to each reversal of the stroke of the piston which mechanism, while permitting forward and rearward movement of the cradle is caused to restrain movement of the cradle with respect to its support in a direction contrary to that of the actual feed. As shown a cradle, 7 on which a drill 6 is mounted has pivoted on opposite sides at its rearward end a pair of plates 12 each carrying three rollers 13, 15 and 16, the roller 13 and one of the rollers 15 or 16 being in contact with a support 9 at any one time. A pair of rocker arms 21 each carry two spring urged plungers 24 and 25 either of which may be in contact with the plate 12 depending on the direction of travel of the cradle. As shown, for forward travel, the plunger 25 is in contact with the plate causing rollers 13 and 15 to be in contact with the support. On reversal of movement of the piston after its forward stroke pressure between rollers 13 and 15 and the plate is reduced by the clockwise movement of the plates 12 and the cradle moves forward, while reversal of movement of the piston after its rearward stroke increases the pressure and prevents rearward movement of the cradle. An adjustable stop 42 attached to the support co-operates with a laterally projecting trip lever 41 to release a catch and allow springs 37 to bring the plunger 24 into contact with the plate and reverse the movement of the cradle. When the cradle reaches the rearmost point of its travel a shoe 65 engages a stud 64 on an auxiliary air supply valve and shuts off air supply to the drill. The rocker arm is reset by hand for forward movement. The speed of movement of the cradle may be varied by adjusting the pressure of the spring urged plungers 24 and 25. The support may be mounted on plates attached to a swivel bar on a column as illustrated in Fig. 3 (Not shown).

Filed: 1920-09-20
Abstract: 151,279. Johnson, C. E. Sept. 18, 1919, [Convention date]. Cutters.-A cutter for repointing phonograph needles of fibre &c., in which a skin of comparatively hard material covers a softer portion, the harder part forming the needle point, has two jaws 13, 23 pivoted together by a pin 12 and each provided with a depression freely accommodating a knife 14 and a backing-plate 24 respectively. The plate 24 is provided with an angular opening 25 communicating with a pocket 26 on the outside of the jaw 23 for the reception of the needle 30, which is triangular in shape, the edge of the jaw 13 serving as an abutment for the needle. The blade 14 is adjustable, to vary the depth of the cut by means of a screw 19, which forces the blade over towards the plate 24 against the action of a spring washer 28 on the end of the pin 12. A slot 20 through the body of the jaw 13 communicates with the depression and serves for discharging shavings. A pin 33 on the member 13 engaging a slot 32 on the member 23 limits the opening of the jaws. In cutting, the shearing action of the blade forces the softer portion of the needle, which is cut first, against the harder skin 31, and the plate 24 serves as a backing for the surface 31, so that a clear cut and a sharp point are obtained.

Abstract: 241,956. Pelich, E. Oct. 27, 1924, [Convention date]. Crank-actuated pumps; stroke, varying; revolving-cylinder pumps; regulating delivery by opening suction and delivery valves.-A revolving-cylinder and reciprocating-piston pump comprises a casing T and a rotary disc K provided with a chamber a, b in which a hollow piston R is reciprocated by a second piston H reciprocating therein at right angles to the direction of reciprocation of the piston R. The piston H is rotatably mounted on an eccentric pin C carried by the casing cover V. The pumping spaces c, d inside the piston R communicate with the suction and delivery channels s, v in a ported cylinder S through ports x, y in the piston R and ports k<c>, k<d> in the rotor K. The pumping spaces a, b communicate with the channels s, v by ports k<a>, k<b> in the rotor K. The output of the pump may be varied by adjusting the pin C relatively to the plane between the channels s, v so that a proportion of each suction and delivery stroke of the pistons occurs while the respective pumping spaces are in communication with the delivery and suction sides of the pump. The output may be varied also by adjusting the pin C relatively to the axis of the rotor K thereby varying the length of stroke of the pistons. A pointer U connected to the pin C and moving over a scale S<t> indicates the output.

A method of fastening bolts in walls and roofs, e.g. in mines &c. comprises providing a bore 1 in the wall &c. inserting into the bore an apertured sleeve 5 containing a flowable and solidifiable binder, e.g. cement mortar, and pushing the bolt 2 into the sleeve to force the binder out through the apertures to fill the space between the bolt and bore wall. The bolt may have a plain shank but preferably has circumferential flanges, and is fixed in the bore substantially along its whole length when the binder solidifies. A frangible washer 7 holds the binder in the sleeve and the bolt is centred and guided by a ring 3 held in the end of the bore by wedges 4. The bolt may be held in its uppermost position during solidification of the binder by wire passing through holes 9 in the ring and wound round the bolt. The binder is sufficiently viscous not to flow through the sleeve apertures until forced by the bolt, and the sleeve may be in two or more parts held together by wire.

Title: Artificial hog cholera virus culture and method of producing same
IPC: A61K39/187
Filed: 1946-09-16
Abstract: A culture medium for the artificial propagation of hog cholera virus is prepared by removing all the protein from a pig serum, for example, by ultrafiltration through a collodion membrane, sterilizing (e.g. by passage through a bacteria-proof filter) the resultant protein-free fluid, diluting with a physiological solution, sterilizing, incorporating into the diluted fluid a small quantity of veticular-endothelial tissue of a cholera-susceptible pig and, if necessary, adjusting the pH of the suspension to 7.4 by the addition of, for example, carbon dioxide.  A small quantity of a cysteine salt, e.g. cysteine hydrochloride may be added to the culture.  The physiological solution is isotonic with, and of the same pH as, blood and has a similar sodium, potassium, calcium and magnesium content to blood. An artificial culture of hog cholera virus is obtained by inoculating the culture medium with a suspension of red bone marrow or other reticular endothelial tissue or blood from a cholera infected pig.

Abstract: 483,283. Prepayment mechanism for meters. COE, A. Oct. 13,1936, No. 27750. Addition to 457,790. [Class 27] Mechanism for prepaying basic charges ; price-changing mechanism.-The prepayment meter described in the parent Specification is modified by providing one or more further stops on the price-change disc 1 between the stops 4 and 12 determining the initial and final rates of charge, so that the commodity is delivered at three or more successively decreasing rates of charge after predetermined quantities have been prepaid. As shown, one such further stop 12a is provided, being engageable with a pivoted arm 5a, whilst the stops 4 and 12 have rearwardly projecting pins engageable with a fixed abutment 5. When the intermediate rate of charge becomes available, a plunger 45 is released by mechanism stepped up at each coin insertion, as described in the parent Specification, and is depressed by the consumer to free the price-change disc 1. A projection 147 on the rear end of the plunger pivots a plate 68, which holds the plunger depressed, and disengages and zeroizes the mechanism controlling operation of the plunger. When the disc 1 is turned by the consumer to the intermediate rate of charge position, the stop 12a trips the arm 5a which, through a connecting pin 152, lowers the plate 68. The plunger 45, is consequently released and returned into locking engagement with the disc 1 by a spring, and the mechanism controlling operation of the plunger is brought into action again to determine when the final rate of charge is due.
