Title: Improvements in heat responsive control circuit
IPC: G05D23/24
Filed: 1962-03-21
Abstract: 970,632. Control systems for heating resistors. GENERAL ELECTRIC CO. March 21, 1962 [April 5, 1961], No. 10857/62. Heading H2H. An electrically heated device 24a, such as an electrically heated bedcover, having a heating resistor element 24 normally energized over a cyclically operated energy regulator 23 from alternating current mains 12, 13 is provided with a safety control device 31 which comprises two signal wires 32, 33 wound together but separated by a material such as nylon having a negative temperature coefficient of resistance, the safety device being physically associated with the heater 24, the control circuit including a relay 17 provided with a copper " slug " 51 so as to be responsive to rectified A.C. but unresponsive to unrectified A.C. Closure of contacts 18, 43 by push-button 44 energizes relay 17 over a rectifier 36 connected between the ends of the two signal wires 32, 33 to bridge contacts 14, 26 of the relay which are in the supply circuit to the heater 24 and to the signal wires. Should the bedcover 24a become overheated the nylon material 34 decreases in resistance, thus permitting a flow of alternating current between signal wires 32, 33. If this flow reaches a significant value, the relay 17 drops out removing the supply from the heater 24. The bedcover is normally switched off by operation of a push-button 47 which causes A.C. to be applied to the relay 17 which then drops out to open contacts 14, 26. Other embodiments are described in which the " slugging " of the relay 17 is effected by means of a capacitor or a half wave rectifier connected across the relay energizing winding. The energy regulator is of the thermal type and is ambient temperature compensated. It is adjustable by means of a screw 62.

Patent GB-635465-A (GB)
Title: Improvements relating to the manufacture of large glass structures, in particular astronomical telescope mirrors
IPC: C03B23/20
Filed: 1948-04-22
Abstract: 635,465. Optical reflectors. JOBLING & CO., Ltd., J. A., PURSER, E. J. JOBLING-, and COX, S. M. April 22, 1948, No. 11120. [Class 97 (i)] [Also in Group XXIII] Relates to the making of a large glass structure, particularly one embodying a plate having a surface contour suitable for forming an astronomical telescope mirror and made from " Pyrex " (Registered Trade Mark), glass. The plate, one surface of which will eventually form the mirror, is made by assembling a comparatively large number of polygonal pieces alongside one another in all directions on a flat support. Hexagonal pieces preferably are used and when assembled resemble a honeycomb. The sides of the pieces are bevelled upwardly and inwardly somewhat, as shown in Fig. 3, so that although the bottom edges of adjacent pieces touch one another a small gap 4 is initially left between adjacent top edges. The pieces may be concave on their under faces and convex on top, as shown, the volume of glass in the convexity preferably slightly exceeding the volume of the concavity. Examples of relative dimensions are given. Alternatively, the pieces may have plane upper and lower faces. The whole is now heated to such temperature that, in the form shown, the pieces subside so that their upper and lower faces become plane, the support 5 (which is provided with apertures 6 to permit air trapped in the concavity to escape) remaining plane and the bevelled sides of the pieces closing up and becoming sintered to one another to form a homogeneous whole. In the case of the initially plane pieces the support, which is carried by a refractory ring, itself sinks to a more or less saucer shape defined by its eventual contact with a shaped refractory lower plate, the edges of the pieces again becoming sintered to form a homogeneous whole plate which takes the shape of the now curved support. Simultaneously, with the sintering of the edges a cellular backing is applied to the upper surface, i.e. to the surface away from that which will be the reflector, this backing eventually forming a support for the reflector proper and imparting rigidity thereto. The backing comprises a large number of glass tripods 7, Fig. 9, interfitting as shown and carrying a similar number of substantially triangular-section glass cups 8 mouth uppermost and also interfitting as shown. During the heating the cups become fused to one another and to the tripods and the tripods to one another and to the plate. Temporary clips straddling the edges of adjacent cups in connection with initially curved plate pieces may be used to supply the necessary pressure during fusing. Temperature conditions and other details or desiderata are discussed in the Specification and devitrification may be suppressed by the technique described in Specification 626,000, [Group XXIII].

The tool 55 is carried in a socket chuck (see below) by a vertically adjustable head 53 which is connected for rotation and vertical movement with a spindle 31 through a dovetailed Oldham'stype coupling 54, 54<1>. Vertical'feed of this spindle is obtained through a hand-lever 39, rack-and-pinion gearing 36 and 37 and sleeve 32. A gear cluster 40 slidably keyed to the spindle and movable by a screw-operated fork, provides the drive to the spindle at different speeds, according to the number of sides of this polygon to be cut. More than two speeds may be provided for. The drive to these gears is obtained from a countershaft 28 driven by the main spindle 24 from the drilling &c. machine. This spindle carries a gear wheel 21 at its lower end which drives in a reverse direction a sleeve 9. The sleeve 9 is bored eccentrically to take a further sleeve 12, also bored eccentrically to take the tool-head 53. These sleeves are relatively adjustable so that the planetary motion of the cutter may be varied from zero to a maximum represented by the sum of the eccentricities of the sleeves. A supporting device 61 for the outer end of the tool is carried by the sleeve 12 with adjustable jaws, the toolcontacting ends of which may be provided with rollers or balls. Sockets.-The socket provided for gripping the tool comprises a sleeve 56 located in a tapered bore in the head 53 and having a number of balls 57 spaced around its periphery adapted to be wedged between the bore and the tool chamber by compression springs 58. The sleeve 56 contacts the member 60 at the lowermost position of the tool and automatically frees it for removal.

Title: Tire retreading mold
IPC: B29D30/06
Filed: 1930-04-08
Abstract: 340,193. Gill, H. A. April 8, 1930. Moulding wheel tyres.-A tyre retreading mould, consisting of a pair of annular mould sections carrying a matrix as described in Specification 297,645, has a pair of rigid rings projecting inwardly of the mould to engage the opposite sides of the tyre and means applied from the axis to move the rings axially toward each other. Grooves 7 are cut in the adjacent faces of the mould sections 1 and the matrix 3 to carry a wire 8. One end of the wire is anchored to the mould and the other end passes tangentially through the slot 10 and is clamped to the eccentric 11. The wire lies normally in the groove 7 in the mould section but when the lever 14 is pulled the wire contracts and grips the matrix 3. A screw 15 clamps the lever in position. Slidablv fitted inside the mould are two rings 16 adapted to grip the sides of the tyre. Each ring is secured to spider arms 17 mounted on the hub 18 through which passes the shaft 19. One end of the shaft is threaded to receive the hand-wheel 20, the other has a cross-pin 21 engaging a slot in the hub. When removing the tyre, the wheel 20 is unscrewed and the shaft turned so that the pin 21 may engage the slot 23 in the hub and the shaft be withdrawn. The rings 16 are mounted on the mould by pins 24 passing through lugs 25. These pins carry pinions 26 which mesh with a gear wheel 27 which is graduated in conjunction with a pointer 30. When the gear wheel is rotated the stops 26 move along the pins 24 and hence adjust the distance between the rings 16. Thus for any sized tyre the wheel 27 is turned to the required graduation and the hand-wheel 20 is screwed up.
