Filed: 1958-12-30
Abstract: 873,340. Roller type tannery machines. MERCIER FRERES. Dec. 30, 1958 [Jan. 3, 1958], No. 41990/58. Class 76. A tannery machine having rollers for treating leathers, hides, skins and the like which comprises a conveying roller which presents the leather to the working roller and which is capable of working in both directions of rotation and a spreader roller operatively connected to the conveyer roller and driven thereby, is characterized in that the drive between the conveyer and spreader rollers allows the latter to rotate always in the same direction irrespective of the direction of rotation of the former. In the embodiment described, the drive between the conveyer and spreader rollers A and B, respectively, is, when the former rotates in the " forward " direction, by the directly meshing gearwheels 2 and 6 allowing the rollers to move in the directions indicated (f<SP>2</SP> and f<SP>4</SP>), the latter gear 6 being of the " freewheel " type making this drive inoperative when the direction of rotation of roller A is reversed. When this is reversed, the drive is by means of the chain-andsprocket system 3, 5 and 7 and direction f<SP>4</SP> is maintained on roller B. The sprocket 5 on roller B is also of the " freewheel " type and inoperative when roller A moves in the forward direction f<SP>2</SP>. Roller B works at a linear speed at least half of that of roller A, at least in the forward direction, when it exerts its spreading function. In the reverse direction it serves to prevent accumulation of leather within the roller system. Specification 741,916 is referred to.

Filed: 1973-09-18
Abstract: 1411046 Bowling alleys J J LEIDL 18 Sept 1973 [20 Oct 1972] 43834/73 Heading A6D Bowling pins 2, Fig 1, at the end of a bowling lane B, are all pulled up by individual cords 4 into the housing of a mechanism M when at least one pin has been knocked down, the pins 2 which have not been knocked down then being lowered back to stand once more in the target area. Each cord 4 is provided with a friction grip detent D, Figs 3, 4, which holds the cord with its bowling pin 2 raised above the target, and with a tension sensor T in the form of a pivoted pawl 64 turned when the cord tightens as its pin is knocked over. As soon as the tension sensor T is actuated a dentent E is released from the associated friction grip detent D. Immediate movement of the friction grip detent D to grip its cord 4 is prevented by a stop S having a bar 88 contacting the detent. Tripping of the tension sensor T and the detent E turns a closed frame 68 about its pivots 74, 76 and operates a valve 82. Compressed air, &c. is thus admitted to two servos 28, energised to move a bar 26 away from the friction gripper D. One end 27 of the cord 4 is fixed, and the cord passes over a pulley carried by the bar 26: the knockeddown bowling pin 2, together with all the other pins, is accordingly raised. As the bar 26, &c. moves back, it is withdrawn from the end of a spring-biassed rod 86, so that a cam 84 engages an end 78 of the frame 68 which is turned on its pivots 74, 76, allowing one side 70 of the frame to raise the tension sensor T clear of the cord 4. When the bar 26 reaches the end of its travel, it engages an abutment 102 on a rod 98 controlling the stop S: the bar 88 is withdrawn from the friction grip detent D, which pivots to its engaged position D", Fig 4, so that a friction member 42 which it carries grips the cord 4 against a counter 24. The bar 26 engages a control 38, Fig 3, at the end of its travel, which reverses the servos 28. The bar 26 then returns, lowering the pins 2 which have not been knocked over back onto the target area of the bowling lane. If all the friction grip detents D have been actuated, corresponding to all the bowling pins 2 being knocked down, a friction gripper sensor bar 104, Fig 3, is lowered, a valve 114 is opened, and compressed air, &c. is admitted to a servo 116 which raises an abutment 130 on a control rod 122 into the path of the lifting bar 26. Engagement of the abutment 130 by the bar 26 acts to pull the rod 122 and thus pivot a lever 46 fast with an arm 44 extending beneath all the friction grippers D. The arm 44 is raised by pivoting of its lever 46, so that all the friction grippers D are in turn pivoted to their disengaged positions, freeing all the cords 4. As the lifting bar 26 returns to its starting position, all the bowling pins 2 are lowered to the target position. The mechanism M, &c. may be pivoted on a fixed frame, Fig 11 (not shown), so that it can be raised for servicing.

Abstract: 1,129,880. Transistor switching circuits. FOXBORO CO. 27 Sept., 1967 [7 Oct., 1966], No. 44055/67. Heading H3T. A switching circuit comprises a field effect transistor 10 connected with its source and drain path connected in series with input and output terminals 11-12, the field effect transistor being switched on or off in dependence on the signal on its gate, and a further field effect transistor 15 of opposite conductivity type to the first having its gate controlled by the input signal at 11 and its source connected to control the gate of the field effect transistor 10. By applying a positive signal to the base of transistor 24, rendering it conductive, the gate of field effect transistor 10 is clamped to the reference potential 25 and is thereby switched off. When transistor 24 is cut-off and hence field effect transistor 10 is conductive, the gate of transistor 10 is controlled by the input signal at 11 through field effect transistor 15, so that the voltage between gate 18 and source 13 of transistor 10 remains constant despite variations in the input signal, and the impedance between source and drain 13, 14 of transistor 10 also remains constant. Analogue signals input at 11 may vary between limits just below the potentials at points 19, 23.

Patent GB-445926-A (GB)
Abstract: 445,926. Electric selective signalling systems. OESTERREICHISCHE - UNGARISCHE OPTISCHE ANSTALT C. P. GOERZ GES., 5, Sonnleithnergasse, and LANG, R., 94, Laxenburgerstrasse, both in Vienna. Dec. 10, 1935, No. 34236. [Class 40 (i)] A transmitter for a resultant field signalling system comprises two sets each of three slip rings, one set being fixed and comprising three continuous rings and the other set being rotatable and comprising one continuous ring and two halved rings, the brush sets being rotated to initiate a transmission and the movable set of rings being driven to follow up the brush-set until the brushes bearing on the halved rings rest on insulating segments. The receiver may comprise two receiving motors, one of which drives an indicator only and the other drives a controlled unit, such as a searchlight, any lag between the transmitting unit and the controlled unit being indicated by a difference between the positions of the receiving indicator and the controlled unit. Alternatively, the receiver may control reversing gear of a driving motor which is arranged to followup movement of the receiver. As shown in Fig. 1, when the transmitting handle 1a is rotated, the brush carrier 5 is moved so that one or other of the half rings 7b<1>, 7b<11> connected to ring 7b completes a circuit through 6b<1>, 6a<1> and 7a<1> or 6b<11>, 6a<11>, 7a<11> to solenoid S<1> or S of the tilting relay. Either contacts K1 and K2 or K1<1> and K2<1> are made so that current is connected in one direction or the other to motors M, M<1> and M<11>. The three motors run in synchronism, the motor M driving sleeve 8, which carries the rings 7b, 7b<1> and 7b<11>, the motor M<1> driving the sleeve 8<1> connected to the remote unit and motor M<11> driving the pointer 8b<11>. When the sleeve 8 overtakes the brush carrier 5 the brushes 6b<1>, 6b<11> rest on insulating segments i<1> (see Fig. 2), so that the relay S, S<1> restores and the motors M, M<1>, M<11> are de-energized. Should the motor M<1> lag behind motors M, M<11>, due to the load of the controlled unit, the pointers 8b<1> and 8b<11> will not be in alignment and the shaft 8<1> can be brought into line by hand. Alternatively, the motor M<1>, instead of driving the controlled unit, may drive the reversing contact 8<1>c (see Fig. 3) of a motor Ma driving the remote unit, a contact disc being also driven by motor Ma to follow-up the brush 8<1>c. The motor Ma comes to rest when brush 8<1>c rests on insulating segments 13a.
