Title: Drive for shaker conveyors by hydraulic transmission
IPC: B65G27/00
Filed: 1947-07-02
Abstract: 627,912. Shaker conveyers. YARMAK, J. July 3, 1947, No. 17496. [Class 78 (i)] [Also in Group XXVIII] A drive for a shaker conveyer includes a pump, the delivery of which is fed to a valveless piston engine which shakes this conveyer, the delivery being continuously variable so that the conveyer may be given a movement having the right characteristic. Figs. 1, 2. Motor 1 drives spindle 3 carrying rotor 5 mounted eccentrically within pump 10. The latter forms a cylindrical guideway within which slide pistons 6 so that rotation of rotor 5 compresses oil into pipe 9 and draws it from pipe 8. This movement of oil is transmitted through pipes 18, 19 to piston 20 which works to cylinder 17 and thus reciprocates the shaker conveyer. Spindle 3 also drives shaft 12 carrying cam 25 through gears 4, 22, 23, 24 ; and cam 25 working against pressure roller 13 formed on the frame 14 of cylinder 10 displaces the cylinder relative to rotor 5 and against the spring 15 so that in the extreme position oil will flow into pipe 8 and out of pipe 9. Hence, as the cam rotates, the frame 14 will move backwards and forwards and cause a corresponding variation in the movement of the oil so that the shaker conveyer will reciprocate with like characteristics. Movement of cam 25 along shaft 12 is effected by handle 26 so as to change the characteristics of motion of the oil. Figs. 6, 7. Motor 41 drives pump 49, and also drives shaft 54 through worm 52 fixed on motor shaft 47. On hollow shaft 54 are loosely mounted gears 57-61 engaging with gears 62-66 fixed permanently on shaft 67. Spring- loaded key 70 is moved along the shaft at the end of spindle 71 which is moved by nut 74 travelling along screw 73 rotated by handle 72, so that the appropriate gear is secured to shaft 54 and the drive is passed to cam 76 slidably fixed to shaft 67. Cam 76 presses roller 77 against spring 78 so that arm 50, on which roller 77 is mounted, is displaced. Arm 50 controls the output and direction of fluid from pump 49, and this fluid is led by pipes 79, 80 to cylinder 84 in which works piston 83 which reciprocates conveyer 97 by means of link 91. Selection of gear by rotation of knob 72, and displacement of cam 76 along shaft 67 by rotation of knob 109 and the consequent displacement of nut 111 securely attached to cam 76, give variation of displacement characteristics of the conveyer. Pump (Figs. 9 and 10). Plate 113 is fixed and provided with curved grooves 114, 115 leading respectively to oil pipes 80 and 79. Cylinder block 116 rotates with shaft 117 and carries pistons 118 bearing against pivoted inclined plate 119. Rotation of block causes reciprocation of pistons so that oil is forced into pipe 80 and sucked out of pipe 79. Pivoted movement of plate 119 varies direction and strength of fluid pressure.

Title: Improvements relating to electrical control apparatus
IPC: B61L7/06
Filed: 1943-10-29
Abstract: 585,805. Railway signals. WESTING- HOUSE BRAKE & SIGNAL CO., Ltd. (Union Switch & Signal Co.). Oct. 29,1943, No. 17901. [Class 105] [Also in Group XXXVIII] In systems for checking the operation of a polarized relay in response to changes of direction in the current in a control circuit, and giving a signal in case of failure of the relay to respond or of failure of the line current, one terminal of the control circuit is connected to the common point of two rectifiers connected in series and associated with an auxiliary relay or a pair of such relays controlled by a contact of the polarized relay. In one arrangement, Fig. 1, the line current is in the normal direction as shown. When the direction changes, the polarized relay P changes over to connect up an alternative signal and current continues to flow through auxiliary relay N in the same direction as before through rectifier K2. If, however, the relay P fails to respond, current in the reverse direction is unable to flow through K1 and the auxiliary relay falls and gives a characteristic signal. The same effect is produced if the current fails. In a modification, Fig. 3, two auxiliary relays NA, NB are provided and are operated one at a time to control the normal signals. If the relay P fails to respond to a change in polarity, the energized auxiliary relay is effectively shunted out by its associated rectifier and with both relays de-energized for this cause or because of a current fahure, a characteristic signal is given. In the arrangement shown in Fig. 5, the invention is applied to indicating the condition of railway points. When the lever L is operated to reverse the current to relay WR, the latter continues to hold its horizontal armatures and changes over the others. The point shifting machine SM operates and reverses the current to a polarized relay P associated with a pair of rectifiers K5, K6 and two auxiliary relays NA, NB with shunting rectifiers K7, K8 to polarize them and make them sluggish. In normal operation, one of these relays is operated in accordance with the condition of the points, but if P fails to respond to a change of condition or if its condition does not correspond to that of the control relay WR or if the current in the circuit of WR or in that of P fails, both relays are de-energized and a signal is given. Similar applications to indicating the condition of railway points are illustrated in Figs. 4 and 6 (not shown) the association of the polarized relay with the rectifiers and auxiliary relays in these cases corresponding with that shown in Figs. 3 and 1 respectively. The rectifier pair is preferably arranged as shown in Fig. 7 with rectifier elements forming parts of the connections to ensure that the rectifier cannot become disconnected, without interrupting a circuit to the relay N. Specification 582,761 is referred to.

Tyres, elastic, special apparatus for making.- Relates to tyre-making machines of the kind described in Specification 120,564 in which plies of fabric are wound on to a rotating mandrel, and consists in means for tensioning the fabric strip during the winding, and power-operated means for positioning the desired stock-roll in working relation with the mandrel. In the construction shown, a pair of stock-rolls 104 (each with the usual take-up roll 104<a> for the liner-strip) is carried on a bracket 81 which is mounted on a crossshaft 86. To bring the lower roll 104 into working position with the mandrel 1, pressure-fluid is admitted to the cylinder 102 so as to raise the bracket 81. Associated with each roll 104 is a tension-roll 85 over which the fabric is guided by other rolls 87. The rolls 85, 87 are of double-cone form as shown, the tension roll being corrugated, preferably helically. In the forward movement of the fabric, the rotation of the roll 85 is retarded by means of an adjustable band-brake 94 fitted around a pulley on the shaft 89. A one-way ratchet-clutch is arranged between the pulley and the shaft, so that the free end of the severed strip may be wound back on to the roll 104 untensioned.

Abstract: 532,521. Wireless receiving circuits. MURPHY RADIO, Ltd., and FAIRHURST, H. A. June 23, 1939, No. 18367. [Class 40 (v)] In a radio-receiver, interference which is in the nature of impulses of short duration is eliminated by means of a diode 4 shunted across the input of the output valve 2. To the cathode of diode 4 is applied a bias comprising a D.C. component from a potentiometer 9 sufficient to bring the diode to the verge of conducting, and an audio-frequency component taken from the secondary of the output transformer 3 to make the cathode potential follow the anode potential for all desired signals. This bias is connected through a delaying network 12, 13, the introduced delay being greater than the duration of the short impulses it is desired to suppress. Normal signals are applied to the anode and cathode of diode 4 almost simultaneously and the diode remains non- conducting. Thus the signal is not interfered with. Short impulses however reach a sufficient value on the anode before they appear on the cathode and are shunted. In the modification shown in Fig. 3, the cathode of diode 4 is supplied from an additional valve 18 branched from the signal channel and acting as a cathode follower. The cathode is fed through a delay network 24, 26 while the D.C. bias is connected to the anode from a tapping on a potentiometer 23.
