Title: Improvements in notching and like presses
IPC: B21D28/22
Filed: 1922-08-28
Abstract: 206,951. Cooper, A. E., and Jones, C. Aug. 28, 1922. Dynamo-electric machines.-A press such as described in Specification 199,756 for notching the edges of segments &c. is arranged to be tilted so that the work-holder which is in the form of a sector will be returned by gravity when released by the feed and indexing mechanism. The machine tilts about pivots b<4> which are coaxial with the driving shaft and is locked by bolts b<6>. The work-holder comprises two bars x, Fig. 3, adjustably pivoted in a slotted guide x<1> and a quadrantal dividing plate w which, between the operations of the press, is advanced, against gravity, by a pawl z, Fig. 4, carried by a slide v which is reciprocated through linkwork b<10>, b<11>, Fig. 2, by a crank disc u on the main shaft. The quadrant w is held, during the return of the pawl z, by a fixed pawl z<1> which lies in a plane above the pawl z. The original position of the quadrant w is adjusted by a screw x<4>, Fig. 3, bearing against a stop w<1>. After the notches have been cut the pawls z, z<1> are withdrawn, as by a bar z<2>, and the quadrant returns by gravity under control of a one-direction brake w<3>, Fig. 6, which is pressed towards the left by a light spring w' and gear w<2> and is adjusted by a screw w<4>. The Provisional Specification describes a notching press with the tools vertically and horizontally adjustable relatively to their plunger which is reciprocated by a clutch carried on its lower end. The clutch may be operated by hand or automatically by the moving work-holder.

Abstract: 912,523. Belt-tensioners. NIMTZ, K., and NIMTZ, H., [trading as VOLKMANN & CO.]. June 28, 1961, No. 23463/61. Class 80 (1). A belt-tensioning arrangement comprises two driving pulleys 1, 2 geared to a common driving or driven shaft and rotatably carried by spring- loaded arms capable of independent swinging movement. As shown in Fig. 2, the pulleys 1, 2 are driven by spur pinions 7, 8 meshing with a pinion 11 on the motor drive shaft, and are carried at the ends of arms 5, 6 pivotally mounted on a member 9 coaxial with the drive shaft, the pulley spindles passing through arcuate guide-slots 16, 17 allowing the arms to swing under the restraint of springs 13, 14. In the embodiment according to Fig. 4 the pulleys 1, 2 are carried by arms 18, 19 pivotally connected to a block 24 subjected to the action of opposing springs 25, 26 in a carrier 27 capable of adjustment by a screwed shaft 30.

Title: Apparatus for actuating an electric switch or indicator by the application of pre-determined numbers of impulses
IPC: H01H63/20
Filed: 1919-09-25
Abstract: 151,818. Angold, H. E. Sept. 25, 1919. Mechanical telegraphs.-An apparatus for operating a switch or indicator by the application of a predetermined number of impulses comprises an element which is moved through a definite distance for a definite number of impulses, but automatically returns to its zero positions when the impulses are stopped, the element being adapted to operate the switch or indicator on its return movement if the predetermined number, or one of a set of predetermined numbers, of impulses has been received. As shown, the element consists in a weighted rack a carrying a pawl d which is moved into engagement with a notch in an arm m or n actuating the switch or indicator. The impulses are applied to the rack by means of a pawl h pivoted at k to a lever j. The return movement of the rack is retarded by the engagement of teeth e on the rack with a train of wheels f, so that successive impulses raise the rack step by step until the pawl d enters the notch in the arm m or n. If the impulses are stopped when the pawl enters either of these notches, the corresponding arm is carried downwards with the rack and operates the switch or indicator, but if the impulses are continued the pawl swings clear of the notches and in the subsequent descent of the rack slips past the arms without affecting them.

Abstract: A catalyst comprises alumina or silica promoted with a heteropolyacid or an alkali metal or alkaline earth metal salt of such acid.  The acid may contain molybdenum or tungsten together with boron, silicon, germanium, titanium, zirconium, thorium, phosphorus, vanadium, arsenic or manganese.  The alumina or silica is impregnated with an aqueous solution of the acid or salt and dried to give a catalyst containing from 0,1 to 10% by weight of the promoter.  In examples the catalysts specified are phosphotungstic acid on activated alumina, silicotungstic acid on alumina, phosphotogungstic acid on activated silica, and potassium phosphotungstate on alumina.  The catalyst may be used in a fixed or fluidized bed reactor.ALSO:Ethyl mercaptan and diethyl sulphide are obtained by reacting hydrogen sulphide with ethylene in the presence of a catalyst consisting of alumina or silica containing 0.1% to 10% by weight of heteropoly acid or an alkali metal or alkaline earth metal salt thereof.

Abstract: 243,320. Soc. Anon. Etablissements Gaiffe-Gallot et Pilon. Nov. 18, 1924, [Convention date]. R÷ntgen-ray apparatus. - The electric supply system of a R÷ntgen-ray tube includes a switching system which cuts out the supply when a predetermined quantity of energy has been supplied to the tube, in order that the radiographic exposure may be rendered independent of variations in the supply current and voltage. An electromagnet 8 in series with the secondary 6 and an electromagnet 9 in shunt with the primary 5 of the supply transformer, produce a torque .proportional to the energy supplied upon a rotary metal disc 10 braked by an adjustable magnet 11, and carrying a contact member 12 which may be adjusted to any predetermined point of a scale on the periphery of the disc. The supply is cut in by manually closing a switch 2. thereby completing the circuit of an electromagnet 3 which closes the circuit of the transformer primary. When the predetermined quantity of energy has been supplied, the contact 12 short circuits contacts 14, and completes the circuit of an electromagnet 15 which opens the circuit of the transformer primary.

Title: Improvements in and relating to target systems and apparatus
IPC: F41J7/04
Filed: 1935-08-24
Abstract: 453,673. Targets. CLEVELAND, F. J., 29, Southampton Buildings, Chancery Lane, London.-(Automatische Fallscheiben Ges. ; 19, Pillnitzer Strasse, Dresden, Germany) Aug. 24, 1935, No. 23790. [Class 20 (i)] Multiple targets are arranged side by side, each target being coupled to transmission mechanism whereby, as it moves back under impact from a bullet, another target in a different position from the former is brought into firing position. In one form, the targets are fixedly mounted side by side on a shaft 2 adapted to rotate in bearings on pedestals 1, these bearings being provided with spring-ball stops 8 corresponding with the positions of the targets, the stops being adjustable as regards pressure and separately releasable by means of grooved heads 11 and catches 15. Grooves 7 in the shaft coact with the stops to maintain each of the targets 3-6 in exposed position in turn. In another form, Fig. 7, the targets 19 are loosely mounted on a shaft 17 and each target is connected by a crank 29 to separate grooved discs 30 mounted on a shaft 31, the groove in each disc being displaced relatively through 90‹ ; tappets 39 for each target similarly displaced coact with forked bars 36 pivoted to catch bars 34, the catches being spring actuated towards the tappet shaft. When a target is struck, the crank for that target is actuated and the shaft 31 is rotated so that the tappet corresponding to another target releases the catch 34 of that target and allows the target to rise into exposed position, the struck target being held depressed by its catch 34. A stop 40 may be provided on each catch, or spring stops may be provided in each target bearing to prevent excessive swinging. In another modification, Fig. 8, a tappet shaft 43 is rotated each time a target is struck by a bullet, through the intermediary of projections 44 on the shaft, tappets 45 disposed at 180‹ apart thereon operating spring catches 46 to release other horizontally retained targets in turn, so that these can swing into exposed firing position; the auxiliary shaft 43 is prevented from over rotation by the interacting of a spring 51<a> and a recessed disc 51 fixed to the shaft. In a still further modification, Fig. 10, each target 55 as it is struck is adapted to actuate a push 58 attached to a wire control 57 leading to another target, and to release the catch 61 retaining that target in horizontal position so that it can swing vertically. A safety catch 67 is provided for each target position to retain the release catch in inoperative position, the safety catch being operated by the lower edge 69 of the target as it falls when struck.
