Filed: 1950-07-10
Abstract: 677,036. Kneading plastic material. SVIT, NARODNI PODNIK. July 10, 1950 [July 18, 1949], No. 17169/50. Class 86 A method of kneading and heating plastic materials, more particularly rubber, in a kneading frame in which the plastic material is fed upwards by means of a feed conveyer and is caused to enter between a pair of kneading drums in a direction opposite to gravity forces. The apparatus described comprises a pair of drums 1, 1<1> rotating upwardly at the nip and a knife 14 carried by an arm 16 pivotally mounted and spring-loaded to carry the knife from end to end across the drum 1. Beneath the drum 1 a roller conveyer 2 is urged by springs 12 and 13 towards the lower surface of the drum 1. Material to be kneaded is placed on the conveyer which is then elevated by means of a pedal 3 so that the material engages the drum 1 and is moved thereby inwardly towards the nip of the drums. The springs 12 and 13 urge the conveyer 2 constantly against the lump of material so that the latter is prevented from falling out. The material adheres to the drum 1 in the form of a coating O which is cut along a helix by the knife 14, the cut coating being folded by the operator to form a roll which is replaced upon the conveyer so that the material is fed again between the drums.

Title: Improvements in control system for phonographs
IPC: G11B17/00
Filed: 1940-12-11
Abstract: 545,813. Phonographs. COTTRELL, H. L. (Dictaphone Corporation). Dec. 11, 1940, No. 17551. [Class 40 (ii)] [Also in Group XXXIX] In an electrical dictating machine comprising indirectly heated electronic devices, switching means are provided responsive to the lifting of a microphone and loud-speaker unit from its rest and adapted to supply operative voltage to the heating circuit of the electronic devices, and the anode circuit of at least one of the electronic devices is provided with means adapted to start a driving motor and give a signal when the anode current of the electronic devices attains its operative value after the time required for heating. As shown, the dictating machine resembles that described in Specification 502,423 and comprises a cylindrical mandrel 2 adapted to be driven by an electric motor 10 through a clutch 8 controlled by Bowden-wire mechanism 32 from a push-button 30 on the combined microphone and loudspeaker unit 14. This unit is connected by a cable 16 to a reversing switch device 18 connected to the input 20 and output 24 of an amplifier 22 and by a cable 26 to a combined recording and reproducing device 28. This device can be set for recording or reproducing by a lever 34 connected to the lever 36 which makes the corresponding setting of the reversing switch device 18. The motor 10, the amplifier 22, and a rectifier 58 are supplied from a source 50 through a main switch 52 and a fuse 54, and according to the invention, a control circuit 56 with signal lamps 98, 99 is provided in association with a mercury switch 40 to operate as follows. When the microphone and loudspeaker unit 14 is on its hook 37 as shown, the conta,cts of the mercury switch 40 are open. If then the main switch 52 is closed, subnormal heating current is supplied through resistances 74, 76 to the heaters 80, 78 of the several electronic tubes in series, and to a red lamp 98 to indicate this state of things. The machine is otherwise inoperative. When the unit 14 is lifted off its hook 37, the hook is lifted by a spring 44 and tilts the mercury switch 40 to close the contacts 45, 46, 47 therein. Resistance 74 is thus short-circuited and full operative current supplied to the heaters of the electronic devices, which, however, take some time to become operative. When this stage is reached the anode current of the rectifying tube 66 which passes through a relay coil 88 through contacts 91, 92 operates this relay to break the contacts 91, 92 and change contact 94 from 93 to 95. The opening of the contacts 91, 92 introduces a resistance 90 in the circuit of the coil 88 to reduce the working load of the relay 88 on the rectifier while still maintaining the relay in action. The change of contact 94 from 93 to 95 switches the red lamp 98 off and the green lamp 99 on, and at the same time completes the circuit of the motor 10, the green lamp serving to indicate this operative condition of the machine.

Abstract: 1,262,128. Transistor bi-stable circuits. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. 3 April, 1969 [9 April, 1968], No. 17583/69. Heading H3T. In a master-slave J-K bi-stable the inputs of the master bi-stable T 1 T 2 T 1 <SP>1</SP>T 2 <SP>1</SP> are fed from gates G, G<SP>1</SP> which respectively receive the signals J, K, Q and clock, and J, K, Q and clock, and the master bi-stable remains sensitive to the J and K inputs during the whole clock pulse and not merely at the beginning thereof. The slave bistable, comprising transistors T 11-13  and T 11 <SP>1</SP> -13 <SP>1</SP> cross-coupled through transistors T 9 , 10  and T 9 <SP>1</SP>, 10 <SP>1</SP>, receives the master output through clock-controlled transistors T 14,14 <SP>1</SP> and produces the Q, Q outputs. The cross-coupled transistors T 1 , T 1 <SP>1</SP> of the master are switched by the respective parallel transistors T 2 , T 2 <SP>1</SP>. For example, T 2  conducts (to turn on T 1 ) by current flow to its base from complementary transistors T 7 , T 8  provided that: clock pulse T is positive to hold T 7 T 8  on, and neither T 4  nor T 5  of gate G conducts to divert this current from T 2 . The bases of T 4 , T 5  are connected to the collectors of transistors T 3 , T 6  which receive input signals thus: K at T 3  base, Q at T 3  collector and T 6  base through R 1  and R 2 , and J at T 6  collector. In the similar gate G<SP>1</SP>, parallel transistors T 4 <SP>1</SP>T 5 <SP>1</SP> and their associated transistors T 3 <SP>1</SP>T 6 <SP>1</SP> receive input signals thus: J at T 3 <SP>1</SP> base, Q at T 3 <SP>1</SP> collector and T 6 <SP>1</SP> base through R 1 <SP>1</SP>R 2 <SP>1</SP>, and K at T 6 <SP>1</SP> collector. The master transistor T 1  only turns on if, during the clock pulse, J is 0 and Q is 1, or K is 1 and Q is 0; and T 1 <SP>1</SP> turns on if, during the clock pulse, K is 0 and Q is 1, or J is 1 and Q is 0. When the clock pulse ceases to be positive the input gates G, G<SP>1</SP> to the master are blocked, and the master sets the slave. Set and reset inputs for master and slave are provided at S, S<SP>1</SP>. In a modification (Fig. 3, not shown) the transistors T 4 T 5  and T 4 <SP>1</SP>T 5 <SP>1</SP> of gates G, G<SP>1</SP> are connected to the master bi-stable T 1 T 1 <SP>1</SP> through clock controlled transistors T 18 T 18 <SP>1</SP>. The master transistors T 1 T 1 <SP>1</SP> have base diodes D 1 D 1 <SP>1</SP> and do not have the parallel transistors T 2 T 2 <SP>1</SP>.
