Abstract: 1,104,254. Thermal switches. SATCHWELL CONTROLS Ltd. 23 Nov., 1965 [25 Sept., 1964; 29 March, 1965], Nos. 39187/64 and 13285/65. Heading H1N. The temperature of a wash-tub is set by rotating anticlockwise a D-section shaft on which is rigidly mounted a cam 2 and loosely mounted a ratchet-cam disc 15 so that the cam 2 actuates a change-over switch 10 controlling a heater for the tub and the ratchet-cam disc 15 and cam 2 are retained against the action of a spring 7 by a pawl 4 pivoted at 9. When the temperature is reached a diaphragm or bellows 13 lifts pawl 4 thereby releasing ratchet-cam 15 and allowing cam 2 and ratchet-cam 15 to return to their initial position. The ratchetcam 15 may be released manually by rotating the shaft clockwise whereupon a lug depresses the pawl 4. As shown, the cam 2 drives ratchetcam 15 by the co-operation of lug 16 thereon with a lug 17 of the ratchet cam. In an alternative arrangement the ratchet-cam 15 is driven by a separate disc fixed to the shafts. The teeth of the ratchet-cam 15 have different radii to set the temperature.

Title: Signaling extraction circuit
IPC: H04L5/22
Filed: 1976-09-30
Abstract: 1514893 Signalling extraction circuit WESTERN ELECTRIC CO Inc 30 Sept 1976 [6 Oct 1975] 40729/76 Heading H4M A signalling extraction circuit utilizes common control circuitry to extract signalling bits for all of a plurality of t.d.m. digital data groups (digroups), each of which comprises a plurality (24) of PCM channels. Each word of a digroup uses n (8) bits for transmitting information, but the n'th bit is borrowed for signalling purposes in every m (6)'th frame. To identify the latter bits, signalling framing information is inserted into a digroup bit stream, in the framing position of every f'th frame (every alternate frame). The basic framing pattern comprises alternating "1'"s and "0"'s, the signalling framing information being interlaced between these, and taking the form of three "1'"s, followed by three "0"'s the every sixth frame in which signalling bits are to be found, being each first frame after a transition from "1" to "0" or viceversa in the signalling framing information. A signalling subframe pattern store comprising a stored recirculating memory serves to maintain a continuing real time record of the pattern of the signalling framing information for each digroup, as well as a test digroup. When the above pattern (i.e. a "0" preceded by three "1"'s or vice versa) has been recorded, a signal bit store is enabled to receiver the 8th bits of the words of the digroups in the following, signalling, frame. Should an out-offrame condition, or tendency thereto be detected, the stored, signalling bits are recycled.

Abstract: 946,425. Photo-electric tracking. KOLLSMAN INSTRUMENT CORPORATION. Nov. 16, 1961 [Nov. 23, 1960], No. 41101/61. Heading H4D. In a light source tracking device of the type in which an image formed of the source by a telescope objective 2, Fig. 1, is scanned in one or more directions perpendicular to the optical axis by a mechanism 3 for the derivation of error signals from photo-electric means to actuate a servo-mechanism 7 controlling the orientation, the scanning mechanism comprises a driven tuning fork on one tine of which is mounted either a photo-sensitive device to perform the scanning directly or an apertured plate to co-operate with a photo-multiplier 5 in scanning. Two tuning forks 63 and 64, Fig. 11, are mounted perpendicular to each other and the optical axis and to one tine of each is fixed a plate containing an aperture (slots 70 and 72 respectively). Coils 65 and 66 surround the respective other tines and excitation of the coils with A.C. at the natural frequency of the forks causes them to oscillate due to interaction with respective permanent magnets 67 and 68. The coils are alternately excited to cause scanning in azimuth and altitude alternately by the square aperture defined by intersection of the slots 70 and 72. In another embodiment only one fork 8, Fig. 6, is employed to oscillate a circular aperture 10 which scans alternately in altitude and azimuth by switching of the mounting 11b of the fork between the two extremities of a quadrantal guide 20 concentric with the telescope. In each embodiment the output of the photo-sensitive device contains a signal component 15, 16, Fig. 4, at the oscillation frequency fo of amplitude and phase proportional to the magnitude and sense of the displacement of the image from the centre of the scan and a signal component 14 of frequency 2 #o having a maximum amplitude when the image is at the centre of the scan. A circuit, Fig. 10 (not shown), utilizes these components to control the orientation of the telescope as described also in Specifications 946,224 and 946,426.

An integral flange and drive shaft unit comprises a drive shaft friction welded to an end flange the friction welded parent metal being surrounded by part of the flash produced during welding, surplus having been removed. A cylindrical steel shaft 12, Fig. 2, has a splined section formed on one end for engagement with a differential gear and has a chamfered frusto conical surface 17 at the other end with a flat end surface 18. A wheel attachment flange 14 having bolt holes 22 is provided with a recess having a frusto conical surface 23 and a flat bottom surface 24. The flange and shaft are relatively rotated while they are urged together so that initially the surfaces 17, 23 engage but the surfaces 18, 24 do not. When sufficient heat is generated the engaged surfaces deform to bring the surfaces 18, 24 together and soon all the engaged surfaces become plastic. Relative rotation is arrested and axial pressure is maintained so that an annular flash 26, Fig. 4, extends from the shaft and an annular flash 27 extends from the flange. The flash is ground off around the cooled joint on the line 31 so that the root area of the shaft is increased and has a smooth outer radius. In another embodiment the shaft has a simple flat end surface and engages during friction welding a smooth flat surface on the flange. A joint similar to that already described is obtained. After grinding the weld flash the shaft unit is heat treated and shot peened for hardening.
