Title: Improvements in systems for exploring space
IPC: F41G7/22
Filed: 1956-04-05
Abstract: 918,340. Photo-electric tracking systems. LABORATOIRES D'ELECTRONIQUE ET DE PHYSIQUE APPLIQUEES. April 5, 1956 [April 6, 1955; April 15, 1955]. No. 10508/56. Class 40 (7). [Also in Group XXXV] A " space exploring " radiation detector has an epicycloidal scan to collect radiation within a certain cone of space, and is provided with automatic tracking to maintain a detected radiation source within and near the axis of the cone. Epicycloidal scan, Figs. 1, 3.-A detector, (e.g. a photo-cell), at o receives radiation from small cylinders around axis OI, which rotates about the axis OX, and in addition the cylinder rotates at a higher speed around the axis OI whereby a cone of space is scanned with a scanning trajectory as illustrated in Fig. 2 (not shown). This may be achieved by a large concave mirror M1 driven by a motor ml to scan around the axis OX and deflect radiations on to a smaller convex mirror M2 driven by a motor m2 at a higher speed than the motor m1 and reflecting radiation on to a detector D. An indication of the position of detected sources of radiation, may be given on a C.R.T. modulated by the output of the detector and having its scanning coils energized from oscillators C1, C2 supplying the mirror-driving- motors. Automatic following, Fig. 6.-The rectangular co-ordinates of the source of radiation with reference to the axis of the system are obtained from sin/cosine resolvers 20. 21 driven by the mirror-driving-motors m1, m2 and energized by the amplified output of the detector D. The sine and cosine components are added and integrated at 24, 27 and the resultant signals used to energize motors m3, m4 which orient the scanning system so that the signals are reduced to zero, i.e. the axis of the apparatus is directed on the source of radiation. Fig. 5 (not shown), illustrates in more detail the orientation drive shown schematically in Fig. 6. The scanning system is mounted in a cordon joint, and oriented by a pin 6 passing through two members 14, 15 slotted at right-angles and rack-driven by the motors m3, m4. A suitable integrating circuit is described, Fig. 7 (not shown), in which the charge on capacitor 34 is transferred by transformer 36 to a capacitor 35 when triode 30 is pulsed once a scanning cycle, just after triode 31 has been pulsed to discharge the capacitor.

Abstract: 105,516. Haddan, A. J. H. (National Cash Register Ou.). April 11, 1916. Cash registers with operating- means; differentially-moved indicators.-The indicators are actuated by members having pear-shaped slots which are engaged by pins upon constant-excursion members guided by differentially -set slots so that the indicators pass direct from one position to another. The invention is set forth with reference to the machine described in Specifications 105,397 and 105,511. Each main differential member carries a pin 255, Fig. 1, which engages a slot upon a bell-crank lever 257 having teeth 260 which co-act with a camoperated locking-pawl 261. A pin 274 upon a cam-operated link 275 runs in a slot 259 in the bell-crank and engages one side or the other of a rear-shaped recess 281 upon a yoke 282 carrying a segment 283 in gear with the indicator pinion; the movement is transmitted by segments 286 to operators' indicators. The transaction indicators, Fig. 5, are similarly actuated through bellcrank levers 289, but they are articulated to enable the corresponding main differential members to be moved at varying times during the operation of the machine. A part 290 of each flange is provided with a flange 293 which overlaps the upper edge of the arm 289, so that the part 290 is rocked when the arm is rocked counter-clockwise, but allows the arm to return while the part is locked in adjusted position. Flashes.-Flashes 315, Fig. 5, are carried by arms 314, extensions 316 of which engage slots 318 in a vertically guided bar 319, which carries at its lower end a pin 321 engaging a forked arm 323; this arm is pivoted upon a shaft 126 and has integrally connected therewith an arm 325 pivoted to a cam-operated link 326. Item and operation counters.-Operation counters 343, Figs. 7 and 9, are provided, one for each class of transaction, and one to register the total number of operations; their pawl-carrying operating-arms 345 are adapted to be engaged by arms 348 mounted upon a shaft 349, which is moved axially from the transaction indicator. The arm for actuating the total-operation counter has an extension 349a to enable it to actuate in all positions of the shaft 349. To actuate the counters, this arm is oscillated through a link 1361 and bellcrank lever 1362 from a cam upon the main cam shaft of the machine.

Abstract: 857,711. Discharge lamps. GENERAL ELECTRIC CO. April 3, 1957 [April 19, 1956], No. 10932/57. Addition to 821,321. Class 39(1). A discharge lamp, particularly a fluorescent lamp, of the parent Specification having a vitreous envelope of generally tubular form with a transversely re-entrant groove extending longitudinally of the envelope to form a discharge space 1 with a kidney-shaped crosssection, has the regions of maximum stress at the bottom C of the concave groove forming wall portion 18 and at the convexly curved wall portions 19 and 19<SP>1</SP> on either side of the groove of increased wall thickness relative to the remainder of the envelope wall. The ratio of maximum to minimum wall thickness throughout the cross-section of the envelope is not in excess of approximately 3 : 1 and is preferably approximately 2 : 1. The side walls 21 and 21<SP>1</SP> of the groove are substantially straight portions inclined at an angle of more than 15 degrees, e.g. 27 degrees, to the medial plane through the groove. Concave inner wall 18 has a greater curvature than convex outer wall 17 and which can be three times as great, and convex wall portions 19 and 19<SP>1</SP> have a slightly greater inside curvature than concave wall 18. The filling comprises an inert gas, e.g. argon at a few mms. pressure, and mercury vapour at a pressure of 1 to 20 microns. The envelope can be made by drawing grooved and differentially thickened tubing directly or by reforming a differentially thickened tube of circular section. The reforming can be done by heating the round tube to its softening point and then clamping a suitable mould about it, or by heating the tube in a selected zone corresponding to the region of the groove to its softening temperature, e.g. approximately 540‹C. in the case of lime glass, and pressing on the tube in the heated region a plunger with a protuberance.
