Title: Improvements relating to means for controlling winding and reeling apparatus for wire and the like
IPC: B65H59/38
Filed: 1939-05-30
Abstract: 529,351. Winding wire &c. BRITISH THOMSON HOUSTON CO., Ltd. May 30, 1939, No. 15913. Convention date, May 28, 1938. [Classes 120 (ii) and 120 (iii)] In drawing wire, &c. 10 from a supply reel 11 and winding it on a driven reel 12, the wire is passed around a capstan drum 21 and the drum and reel 11 are respectively coupled to motors 24, 27 which give a constant torque over a wide range of speeds, the torque of the motor 24 opposing the rotation of the drum and tensioning the material leaving it and the torque of the motor 27 opposing the feed of the material from the reel 11 and tensioning the material fed to the drum. The tension in the material may be adjusted by varying the torques of the motors, e.g. by having adjustable resistances 28, 29 connected in the armature circuit of the motors and the tension may be indicated on a scale 33, the actuating element 32 of which is connected to a pivoted lever 30 carrying a roller 22 riding on the wire &c. 10.

Title: Wet clutch with coolant distributor
IPC: F16D65/853
Filed: 1974-04-10
Abstract: 1455467 Friction clutches BORG-WARNER CORP 10 April 1974 [19 Nov 1973] 15997/74 Heading F2C Cooling of a wet friction clutch is achieved by the provision in the driven plate 14 of slots 28, angled as shown with the plate rotating clockwise relative to a driving member and diverter members 30 positioned radially out from the friction pad 48 and each having a leading finger 33 which diverts fluid into the slots 28. From the slots 28 the cooling fluid is centrifuged out through grooves 50, and also flows into intersecting grooves 49, to cool the friction pad 48. The diverter members 30 dip into cooling oil in the clutch driving member at the lower part of the driven plate 14. The members 30 may be in the plane of the plate 14 or slightly angled thereto (Fig. 3, not shown) to enhance the scooping action. The clutch plate 14 may be slightly bent to facilitate disengagement (Figs. 4 and 5, not shown). The described clutch is engaged by a diaphragm spring which clamps plate 14 between a presser plate 64 and a flywheel (Fig. 1, not shown), the cooling oil being in a reservoir rotating with these members so that the fluid is scooped up during engagement or disengagement due to the relative rotation between driving and driven members.

Title: Electric shunts for instruments or other devices
IPC: G01R1/20
Filed: 1925-06-22
Abstract: 244,657. British Thomson-Houston Co., Ltd., (General Electric Co.). June 22, 1925. Resistances, self-supporting; contacting solid resistances; temperature errors, compensating for. -A shunt for an instrument &c. is provided with means for adjusting its temperature coefficient of resistance. A cast-iron member 10, ribbed as shown to dissipate heat, is provided with a central bore 13 threaded to receive adjustable nuts 15 and lock-nuts 16, between which is a stack of carbon discs 14. The temperature coefficient of the shunt is varied by adjusting the resistance of the carbon discs 14 by altering their number or dimensions or by screwing up or unscrewing the nuts 15, thereby varying the ratio of the resistances of the current paths through the cast iron and the carbon discs, which are of positive and negative coefficients of resistance respectively. Owing to the coefficient of expansion of carbon being somewhat higher than that of cast iron, the compression increases at increasing temperature. This has the same effect as the negative coefficient of the carbon. Bolt holes 17, 18, 19, 20, 21 are provided for the shunt lead terminals. Since the temperature coefficient of that portion of the shunt between the upper terminal 17 and the upper nut 15 is entirely positive, a further adjustment of the total temperature coefficient is obtainable by changing the position of the upper shunt lead from one to another of the terminal holes 17, 19, 20, 21. The upper and lower surfaces of the shunt are machined, the line terminals 12 being bolted thereto.

Title: An article recognition system suitable for automatic tool selection
Inventor: SHARP ROYDS
IPC: F15C1/00
Filed: 1968-04-03
Abstract: 1281511 Fluidic systems NATIONAL RESEARCH DEVELOPMENT CORP 2 April 1969 [3 April 1968] 16137/68 Heading G4P Machine tools in a rotary magazine are coded with an n-bit word represented by relatively raised and depressed surfaces, Fig. 1 (not shown), the words being presented in turn before n pneumatic proximity sensors which develop a succession of corresponding n-bit pneumatic pressure output words. An n-bit word read from a punched tape by n similar sensors is compared with the output words, and when the words compared are the same the magazine is stopped and the tool selected. The comparator comprises n fluidic circuits, each as in Fig. 3. If sensor 10, sensing one bit of the tool word, gives a sufficiently high output unit 21 gives an output on 22 to exclusive OR gates 23, 25 which also receive an output from sensor 19 sensing the corresponding bit on tape 18. There is thus no output at 27 when the bits are alike. The n outputs 27 are fed to OR gates 28, Fig. 4, which feed NOR gate 31 via OR gates 29, 30. Gate 31 receives an additional input from a sensor 33 sensing a surface 34, Fig. 7, associated with, and occupying a lesser circumferential distance than, the code word 12 on the tool such that there is no signal on line 35 when the code word is positioned precisely before the sensors 10. Thus if the word is so positioned and if it agrees with the word on the tape, gate 31 gives an output which latches OR gates 37, 38, resulting in an output on line 40 which stops the magazine. When the tape is moved a reset signal is fed to line 41. The presence of a word is detected by a further sensor 43, Fig. 7, which senses surface 42 associated with, and occupying a greater circumferential distance than, word 12 and which controls supply valve 45 to prevent excessive air consumption, the air supply to sensors 10, 19 and 33 being stopped when there is no tool word before sensors 10.

Abstract: 800,085. Food canning. BORDEN, CO. May 29, 1956 [June 2, 1955], No. 16554/56. Class 49. A canning and processing machine for evacuating and gassing cans containing solid foods comprises means for delivering unsealed cans to an elongated chamber 14 having charging 30 and discharging doors 46 which, when closed, give gas-tight closure, a counter mechanism 22 which activates, when the chamber is full of cans, a timing device 25 which, by making and breaking electrical circuits in sequence activates means for opening and closing the doors, means 38 for evacuating air from the chamber and means 42 for introducing inert gas to the chamber. In operation, cans from a filling and semi-closing equipment 10 pass along a conveyer 12 to the chosen chamber 14 by means of sweep-off plates 18. When the chamber is full a motor 24 is started which drives the timing device 25 which activates, in turn, a solenoid 20 to move the plates 18 to the inactive position, a solenoid 26 to close the door 30, then connects the chamber with a vacuum pump, the connection being broken at a predetermined value, and being replaced by connection to the inert gas, this connection also being broken at a predetermined value. The rear door 46 is raised by the solenoid 45, whilst a slide 47 is aligned with the discharge end of a conveyer 52. Cans pass down this slide 47 to a discharge conveyer 62 which takes them to standard sealing equipment. After the cans are discharged, door 46 is closed, door 30 opened, and chamber 14 filled for the next cycle.

[Class 94 (i)] Razor blades A, Fig. 3, are attached to wrappers 36 by depositing them thereon so that the outer apertures are engaged by turned up tongues 37, which are then flattened to secure the blades. The blades are fed singly from a pile 35 by a slide 28 in a guide 27 to position A<1>. At this point a gripper 10, having resiliently mounted conical jaws, is depressed by a punch 19 and enters the central perforations of the blade. The grippers are mounted on an intermittently rotating table 9 which is held in correct position during the engagement of a blade by the entry of an abutment 45 on the punch into a corresponding recess in the table. The punch recedes and the grippers rise to their upper position. A series of steps bring the blade to position A<11>, a punch 17 depresses the grippers which are pressed together by abutments 41 so that they release the blade which falls upon the wrapper strip 36 in such a position that the outer perforations are engaged by the turned up tongues 37. The wrapper strip is fed by a drum 7 having projections 8 which turn the tongues 37 upwards into receiving position, blades 38 forcing the strip on to the drum to effect this. After the strip has passed away from the receiving position, the tongues are pressed down by an inclined folder.
