Title: Method of and mill and rolls for cold forming disks
IPC: B21H1/02
Filed: 1960-05-11
Abstract: 949,971. Rolling. KELSEY-HAYES CO. May 11, 1960 [May 18, 1959], No. 16596/60. Heading B3M. A mill for cold-forming wheel, harrow, turbine, &c. discs of variable thickness from blanks B of substantially uniform thickness comprises two pairs of forming rolls 61b, 62b, Fig. 5, one or both rolls of each pair having a substantially constant diameter portion a-b and a portion d-e of progressively increasing diameter for restraining a portion of the disc as other portions are reduced by rolling. The rolls are on spindles 44b and 45b, Fig. 3, in housings 39b, 41b mounted on pivots 52b on posts 53a, 53b supported on carriages 63a, 63b which are traversed by a cylinder 66 connected to carriage 63a. A rack 72 on carriage 63a, through a pinion 74 and a rack 75 on carriage 63b, moves carriage 63b in a direction opposite to that of carriage 63a. Plungers 54b (Fig. 4, not shown) acting between the housings 39b, 41b bias roller-followers 47b, 48b on the housings against cams 37b, 38b supported on wedges 23b, 24b, 31b, 32b in a frame 11. Cylinders 33b, 34b operate the wedges 31b, 32b for bringing the mill-rolls 61b, 62b into and out of the rolling positions, adjustment of the roll-opening being by wedge 24b which is operated by a cylinder 26b. Drive for the rolls is by motors 55a, 55b and gear units 58a, 58b on the carriages 63a, 63b. One or more blanks are placed between a spindle 76 and a cylinder-operated clamp 77 by a loading device 79 (Fig. 1, not shown) and subsequently unloaded by a device 81 (Fig. 1). The rolling operation starts with the rolls in position R1-R1, Fig. 5, the rolls being closed on to the blanks B by the cams and rollers 37b, 38b, 47b, 48b as the carriages draw the rolls towards the circumference of the blanks. Roll-portions a-b effect a burnishing operation, portions b-c a reducing operation, c-d a relieving operation serving to concentrate the reducing action to b-c, and d-e-f a leading-in operation. Portion d-e also confines the edges of the blanks, preventing curling and causing the radial compression forces due to rolling to elongate the d-e portion of the blank. Portion a-b may be at the same or slightly greater angle than the angle of taper of the disc. The rolls are opened at point R3-R3 for removal of the discs. In a modification, Fig. 6 (not shown), the upper roll on one side and the lower roll on the opposite side have a longer portion a-b than the co-operating rolls.

Title: Impact pulverizer
IPC: B02C13/09
Filed: 1950-07-04
Abstract: 704,954. Impact pulverizers. PALLMANN, L. July 4, 1950, No. 16683/50. Class 59 Apparatus for grinding materials of all kinds is characterized in that it includes an impeller by means of which the material being ground is flung against the walls of a housing (grinding chamber) consisting of two plate-like impact shells the periphery of each of which is of truncated conical form and is provided with a rough, serrated, corrugated or other unevenly formed hard surface for splitting off or tearing off the outer surface layer of the particles of the material being ground and in which one of the impact shells rotates in a direction opposite to the direction of rotation of the impeller and a slot of adjustable width is provided between the two shells for the withdrawal of the ground material. As shown the mill comprises frustoconically shaped impact shell members 9, 19, housing a centrifuge thrower wheel 17 the member 9 being rotatable in a direction opposite to that of the wheel whilst the member 19 is. adapted for axial displacement to thereby vary the width of the discharge slot 24. The impact shell members 9, 19 are provided-with abrading plates 11, 22, respectively, the surfaces of which are grooved, serrated or otherwise roughened. The rotatable member 9 is mounted, on the hollow shaft 6 carrying the belt pulley 7 whilst the centrifuge wheel 17 is keyed to the shaft 14 which extends through the shaft 6 and carries at its outer end the pulley 15: Axial movement of the shell 19 is effected by the screw threaded engagement of three lugs 21 fixed to the shell with three bolts 20 fixed on the mill housing part 5. In operation material fed to the mill through inlet 26 is:thrown by the wheel on to the rotating impact shell 9 from whence it is flung on to the non-rotating shell 19 by which it is flung against the wheel for a repetitive cycle of operations. Each impact tends to disintegrate the material, particles of the required degree of fineness being discharged through the peripheral slot 24 to the outlet 25. Material may be fed to the inlet 26 i by means of a worm or like feeding device. The bearings of the wheel 17 and the shell 9 are kept free from ground particles by air streams flowing outwardly away from the axis of rotation, the air for such being introduced into the mill through inlets 27, 28 provided in the machine housing part 4 and the shell 9 respectively, near the axes thereof. In order to control the air streams the size of the openings 27 may be varied by adjustable cover plates or the like.

Title: System of voice frequency alternating current signalling and impulsing
IPC: H04Q1/45
Filed: 1936-06-15
Abstract: 476,880. Automatic exchange systems. PANSTWOWE ZAKLADY TELEI RADJOTECHNICZNE, w WARSZAWIE. June 15, 1936, No. 16687. Convention date, June 15, 1935. [Class 40 (iv)] In a voice frequency signalling system, an impulse repeating relay is energized by the end of one train of A.C. and is de-energized by the succeeding train. The effective length of impulses is thus rendered independent of the transmission characteristics of the junction over which the signal is received and the receiving circuits. The invention is described with reference to the control of power driven switches by a register-controller at a previous exchange. When the group selector GW1, Fig. 4, seizes the junction circuit shown, CR is operated over the test circuit and, on the relapse of KR in the register controller, ST pulls up over the a-wire and is followed by SH1 which locks and SH2 which connects an 800-cycle generator G800 to the junction. At the incoming end, Fig. 5, Sel responds to the 800-cycle current and is followed by relay SE2 and the centring and clutch magnets CE, SE of the incoming selector GW2. SE2 sends a train of 600-cycle current back over the junction. This train is terminated shortly afterwards and replaced by a train of 1000-cycle current by the energization of TB over the interrupter on the switch. On the release of TB the 1000- cycle train is terminated and a new 600-cycle train is started and so on. At the outgoing end, EN in response to the beginning of the 600-cycle train energizes EK which locks. At the end of the train EN falls, energizing the repeating relay BJ and EH, which responds to the beginning of the 1000-cycle train, brings down EK but holds BJ. The relapse of EH at the end of this train releases BJ to complete the impulse to the register controller. The beginning of the next 600-cycle train energizes EN, EK as before and so on. When BJ falls back to terminate the last impulse of the digit, KR is energized and locks releasing ST to stop the switch. The Specification as open to inspection under Sect. 91 refers also to a system in which selection is effected by single impulses of currents of different single or multiple frequencies and of different durations. This subject-matter does not appear in the Specification as accepted.

Title: Tripping mechanism for handling and conveying systems
IPC: B65G47/96
Filed: 1973-04-09
Abstract: 1432474 Discharging carriers of endless conveyers SPEAKER MOTION SYSTEMS Inc 9 April 1973 [10 April 1972] 16944/73 Heading B8A Carriers 1 of an endless conveyer have load carriers 9, 10, which may be selectively discharged by the action of a tripping member 28 pivotally mounted on the conveyer frame at the desired discharge station, when the member 28 is in a set position. When it is in this position it is held from movement away from the set position until a member 46 is lifted by the action of a ramp 33 carried at the downstream end of the carrier 1. Until the member 28 is moved to its set position by operation of a control unit (6) (Fig. 1, not shown) the members 28 and 46 are retracted (Fig. 5). This operation causes energization of a solenoid 29 against the action of a spring 42. A forked member 30, rigid with the member 28, deflects a roller 41 carried on a crank, rigid with a crank 32 which carries the member 46. The roller 41 now obstructs the movement of a portion 31 of the forked member 30 until the member 46 is lifted by the action of the ramp 33. The member 46 is a roller, but in a modification (Figs. 7 and 8, not shown) this is replaced by a pin-shaped lever (64).

Title: Improvements in Rotary Proportional and Inferential Meters.
Inventor: THORP FRANKLIN
IPC: G01F15/02
Filed: 1917-11-20
Abstract: 117,207. Thorp, F., and Thorp, H. T. Nov. 20, 1917. Gas meters. - Relates to meters of the rotary proportional or inferential type, and the object of the invention is to prevent the flow of gas &c. through the meter when the rate of flow falls below a predetermined minimum. In the form shown in Fig. 1, a disk a is mounted on the valve spindle c and is surrounded by a ring b, the space between which and the disk edge is so restricted that though with a normal flow of gas the disk is supported thereby well above the ring b, when the flow falls below a certain rate the disk descends within the ring and the flow is further restricted, allowing the disk a and valves d to close. A brake m is connected to the valve spindle c to prevent over-running of the rotor n and to engage the rotor when the valve closes. Fig. 6 shows a form in 'which the disk a itself forms the control valve, being connected by a hollow seem p to a diaphragm o so that the valve is held closed by the pressure of gas on the upper side of the diaphragm o, which is of greater area than the disk a. When the 'disk a is raised, however, the pressure on both sides of the diaphragm o becomes the same, and the valve remains open if the flow of gas is sufficient. In all forms, a means for opening the valve, to start the flow of gas, is provided, an externally operated trigger g co-operating with a spring-pressed element f being employed in the form shown in Fig. 1. A spring as described in Specification 5791/05 may be employed when the valve opens with and not against the pressure of the gas.
