Title: Improved hydraulic head for cutting-out presses
IPC: C14B5/00
Filed: 1957-09-09
Abstract: 877,105. Cutting-out presses. BIANCHI, V. L. A. C. Sept. 9, 1957 [Sept. 8, 1956], No. 28403/57. Class 31 (1). [Also in Group XXIX] The hydraulic head of a cutting-out press comprises a piston 4 having a skirt 6 slidable within a lining 8 carrying a plate 9 connected to the piston by means of a spring 11, the space A enclosed by the piston assembly, which is filled with pressure fluid, being variable according to the length of the cutting tool employed. The body 2 of the head and a cap 15 secured to a stand 1 supporting the head are provided with orifices 26, 27 for admitting pressure fluid so as to move the piston between the cap 15 and a shoulder piece 3 formed integrally with the body 2. An orifice 17 in a member 13 is controlled by a needle-valve 18 fitted on a bridge-piece 19 provided with apertures 21 for the passage of pressure fluid supplied through the orifice 26. An adjustable spring-pressed ball valve 23 allows pressure fluid to pass from the upper to the lower side of the piston when the fluid pressure exceeds a given value. To adjust the space A within the piston assembly for a given cutting tool 29 resting on a table 30, the needle-valve 18 is closed after a given quantity of pressure fluid has been admitted to the space A. Further pressure fluid is admitted through the orifice 26 and the piston assembly moves downwardly until the piston contacts the shoulder piece 3. The ball valve 23 then opens to allow pressure fluid to enter the space A and cause plate 9 to descend and engage the tool 29. At this moment, the ball valve closes and pressure fluid is admitted through the orifice 27 so that the piston assembly moves upwardly until the piston engages the cap 15. The cutting-out operation is then effected by again admitting pressure fluid to the orifice 26. In a modification, Fig. 2 (not shown), the ball valve is omitted and adjustment of the space within the piston assembly is obtained by operation of the needle-valve 18. The stand 1, Fig. 4, is mounted by means of rollers 32 on a carriage 33 resting on the table 30 by means of rollers 34.

Title: Coincident current memory
IPC: F02B75/24
Filed: 1969-06-05
Abstract: 1,219,250. Magnetic storage arrangements. GENERAL MOTORS CORP. 5 June, 1969 [24 June, 1968], No. 28544/69. Heading H3B. [Also in Division G4] In a magnetic data storage system, each storage matrix has a destructive read-out section having a magnetic core at each addressable matrix location and a non-destructive read-out section wherein only certain of the addressable locations are occupied. The two sections have common Y co-ordinate conductors, and common sense windings S1 S2, Fig. 7, and the DRO section has an inhibit winding running besides its X conductors. The cores are arranged on the conductors and draped over supports 51-54, Fig. 5, having heat sinks 57. The memory timing cycle, with currents as in Fig. 2, may be divided into two portions, DRO and NDRO. NDRO operation.-The pattern of missing cores in the NDRO section corresponds to those locations containing a ZERO. Since adjacent cores are oppositely inclined to the conductors, as in Fig. 7, the omission of certain cores may produce an unbalanced noise output in the sense conductors, and therefore several sense conductors may be used, each diagonally traversing the entire matrix but threading less than a critical number of cores so that the maximum noise is insufficient to cause a ZERO output to be mistaken for a ONE. The noise effects are also minimized by placing more cores on an X conductor than a Y conductor, and driving the X conductors with half read currents N, Fig. 2, of a faster rise time than the half read currents O in the Y conductors, the X currents being initiated prior to both the Y currents and an output strobe P so that the noise in read-out is only that due to the slowly rising Y currents. As a further aid to masking noise, a core at an addressed NDRO location is primed from its remanent condition (R), Fig. 9 (not shown) to the undisturbed opposite remanent state (P) by coincident half-write currents L, M, Fig. 2, the subsequent half-read currents N, O, thereby producing a large output whilst returning the core to its initial remanent condition (R). This priming also prevents possible loss of NDRO information between memory cycles. DRO operation.-To read out of the DRO section coincident half select currents F, G, Fig. 2, are used, the latter having the slower rise time to minimize noise as above, and the output being strobed as at K. To write in this section, coincident half select currents H, I are passed through the X and Y conductors in a direction opposite to the read currents, but before write currents commence the inhibit windings for those mats requiring ZERO input are activated with a current J opposite to the X conductor write current. Selection of appropriate X and Y conductors during the DRO and NDRO portions of the memory cycles is described with reference to Figs. 1, 3, 4 (not shown).

Filed: 1925-11-17
Abstract: 265,702. Dawson, Sir A. T., and Buckham, Sir G. T. Nov. 17, 1925. Interlocking and guarding against wrong movement.-In a motor vehicle of the kind having endless-tracks and road wheels for alternative use the conversion from an endless-track to a wheeled vehicle and vice versa is effected by the power of the propelling engine and means are provided for automatically limiting the movement of the speed-controlling device or accelerator of the said engine when the conversion is being performed. In the construction shown the accelerator pedal A is provided with a pin or lug A<2> and a curved arm B<6> fixed on a shaft B<8> is normally not in the path of this pin so that the pedal can be depressed to its full extent. When, however, the engine is to be used to drive the converting mechanism, a reversing gear forming part of this mechanism is shifted from the neutral position into one of its gear positions by a hand lever C. This lever is connected by slotted links C' to pins b<6> carried by arms B<7> on the shaft B<8>, so that the movement of the lever in either direction from its central position rocks the shaft B<8> in a counterclockwise direction and the arm B<6> into the path of the pin A<2> to limit the depression of the accelerator pedal. In a modification the curved arm B<6> is brought into the path of the pin A<2> by the movement of a lever operating a clutch which couples the engine to the converting mechanism. Specification 265,670, [Class 79 (ii), Motor vehicles, Driving &c.], is referred to.

Abstract: 606,530. Coin-freed article - delivery apparatus. COCA-COLA CO. Feb. 13, 1943, No. 28998/45. Convention date, Jan. 15, 1942. Divided out of 606,497. [Class 27] Articles stored in piles.-Mechanism for delivering driking cups in a beverage dispensing apparatus has means for moving reserve stacks of cups successively into delivery position, such means being controlled by electric contacts which close when the stack in the delivery position is depleted. As shown, four stacks of nested paper cups are accommodated between curved plates 930 secured to a shaft 931 which is urged to rotate anti-clockwise by a spring-loaded cord 941 wound about a pulley 940, but is normally held by engagement of a pivoted detent 955 with a four-tooth ratchet wheel 950 on the shaft. The stack C is in operative relation with the delivery mechanism, which is housed in a casing 910 and is operated to discharge the lowermost cup of the stack into a chute 901 upon momentary energization of a solenoid 906. The armature of the solenoid also rocks a feeler lever 975 connected with it by a light spring 978, but the movement of the feeler lever is normally restricted by contact with the cups in the stack C. When, however, the stack is depleted, the feeler lever makes a full stroke, and its end 981 closes contacts 982 in the circuit of a solenoid 960 which thereupon trips the detent 955 and allows the shaft 931 to make a quarter turn to bring a fresh stack into the delivering position where it falls into nested engagement with the residue of the previous stack in the casing 910. Further quarter turns are similarly made by the shaft 931 until all three reserve stacks have been moved into position. Coin action, weight; coin-discharging mechanism.-An inserted coin comes to rest on and depresses the operating lever of a switch 1022 controlling the solenoid 906. Immediately the armature of the solenoid has completed its stroke, a trigger 990 on it rocks a lever 991 to discharge the coin so that the solenoid is de-energized.
