Abstract: 760,795. Lamp glasses. CIBIE, P. Nov. 5, 1952 [July 21, 1952], No. 27881/52. Class 75(2) A plane or dished lamp glass is provided with striations having surfaces generated' by circular motion of a curved or polygonal generator line 1 about an axis W lying in the plane of the generator line and parallel to the plane of the glass. The generator line 1 is preferably circular; its centre O and the axis W of rotation may be on the same or on opposite sides of the glass and the axis of rotation may be on the striated ur on the smooth side of the glass. In consequence the striations are either (1) concave both transversely and longitudinally or (2) concave transversely and convex longitudinally or (3) convex transversely and concave longitudinally or (4) convex both transversely and longitudinally. A metal stamp 5, Fig. 6, for moulding the glass is formed with juxtaposed and superposed contiguous striations by a cutting tool 7 having a cutting edge corresponding to the generator line. The tool is held ' stationary and the stamp is rotated about the axis W; alternatively the stamp is held stationary and the tool rotated. The tool may be arranged relative to the surface of the stamp so that a part of the cutting edge does not engage the surface over the whole of the travel of the tool resulting in the striations having flat uncut portions as shown at 23 in Fig. 19 or at 42 in Fig. 39. The uncut portions may separate adjacent striations. The striations may also be limited to their upper or lower portions by horizontal planes perpendicular to the moulding block as shown in Fig. 11. A single glass may have several sets of striations of the different types described. The glass is used in conjunction with a parabolic' reflector with a light source 'at the focus and the emitted beam has a cross-section of rectangular or oval form. A pair of opposite sides or the lower horizontal side alone of the rectangular cross-section may be curved inwardly. Specification 715,047 is referred to.

The base plate 34 is penetrated by bores in alignment with the anchor bolts 24, 25, and has a central cylindrical bore 42 that terminates in a base 43. A lubricated plate 47 which has a plane lower surface and a convex upper surface rests on the base 43, while an annular shear ring 35 penetrated by bores in alignment with the anchor bolts 24, 25 and superimposed on the base plate 34 overhangs a peripheral margin of the lubricated plate 47. The base plate 34 and the shear ring 35 are secured to the foundation by bolts 32, 33 which pass through the aligned apertures and are threaded into end fittings 30, 31. These end fittings 30, 31 are flush with the upper surface 20 on foundation 17 and are threaded on to the upper ends of the anchor bolts 24, 25. A support block 50 connected by bolts 54, 55 to the heat exchanger 10 partially underlies the shear ring 35 and has a concave lower surface 51 that conforms with and rests upon the convex upper lubricated surface of the plate 47. The plate 47 which is of bronze or brass has rings machined into its upper and lower surfaces, which rings are filled with a graphite base lubricant. Shear pins 37, 40 depending from the base plate 34 protrude into mating bores 22, 21 formed in the upper surface 20 of the foundation 17, and a shear key 56 centrally disposed on the upper surface of the support block 50 is seated in a keyway slot 57 formed in the lower portion 60 of the heat exchanger 10. Should horizontal forces be experienced which are too large to be dissipated by relative motion between the support block 50, the lubricated plate 47 and the base plate 34, then the shear key 56, the bolts 54, 55 and the shear pins 37, 40 will absorb the balance of the otherwise unabsorbed force.

Abstract: 760,588. Optical systems. WATSON & SONS, Ltd., W. and HOPKINS, H. H. Oct. 4, 1954 [Oct. 9, 1953], No. 27890/53. Class 97(1) A variable magnification system for use alone or in conjunction with other lens systems, for example with a television camera comprises two positive lenses spaced apart and connected together for simultaneous axial movement and an axially movable negative lens located between them, the movements being so controlled that the distance of the final image of an object from a fixed point of the system remains fixed as the magnification changes whilst the distance between the effective object of the front positive lens and the image formed by the near positive lens also remains fixed. Preferably the positive lenses have the same focal length and are so arranged that the magnifications of the three lenses increase and decrease together. The maximum and minimum magnifications of the system may be reciprocals one of the other. Data are given for one example in which a negative lens 11 is located before the system which consists of positive lenses 12, 13 of equal focal length, and a negative lens 14. The positive lenses are supported on a carriage 16 movable axially by wheels 19 engaging rails 21, movement being effected by a wire 22 connected by its ends to opposite ends of the carriage and wrapped around a rotatable operating knob 26. The carriage 16 carries a rack 36 engaging a gear 33 bearing on cam 34 against which is spring- pressed a pin 39 on a support 37 slidable axially and carrying the negative lens 14. The cam 34 is shaped to provide the desired movement of the negative lens. Specifications 639,610, 639.611. 639,612, 646,409, 685,945, 713,024 and 722,325 are referred to.

Title: Improvements in and relating to electrical circuit-breakers
Inventor: COMBI ANTHONY
IPC: H01H71/10
Filed: 1955-09-30
Abstract: 773,193. Automatic circuit-breakers, switch-cases; protective cut-out arrangements. CHILTON AIRCRAFT CO., Ltd. Sept. 30, 1955, No. 27939/53. Class 38(5) A circuit-breaker has a spring-biased switch arm 4, an arm 9, an unlocking lever 16. and an armature lever 21 rotatably mounted on pivot pins 7, 10, 17, 23, the ends of which are housed in cylindrical recesses 28 ... 31 formed in bosses integral with the two parts of a divided moulded casing. Toggle links 11, 12 interconnecting the arms 4,9 and acting as a normally rigid. strut, hold the switch arm 4 closed on the' depression of a push button 25 which is connected to the pivot 13 between the arm 9 and link 11. When the armature lever 21 is turned about its pivot 23 by an electro-. magnet 26 or a bimetallic strip 27, it releases the unlocking lever 16, which, acting under the bias of a spring 18, collapses the toggle to trip the circuit-breaker. Addi-  tional recesses 34 are provided to house a test switch 35 and recesses, e.g. 48, housing the terminals. 2, 1 are so arranged that cable, bus-bar or stud connections may be made to the terminals. Recesses 40 and' projections 32 support a push-button guide 36 and the electromagnet 26 respectively. 'The parts of the casing may be,grooved as  indicated at 56 for the releasable attach-' ment of the circuit breaker to a metal clip 58 on a base member 50. The two parts of the casing may be held together by hollow rivets through which bolts may extend to damp a number of circuit-breakers together to form a multipole unit (Fig. 8, not shown). In this case the intermediate pivot pins 14 of the respective toggles would be interconnected for common tripping and the push buttons would be connected by a bar for common operation. Thus in Fig. 17 five single pole circuit-breaker units are interconnected to form a three-phase circuitbreaker in which the three central units are connected between the supply L1... L3 and the load P1 ... P3 and have overload responsive coils b and bimetals 27, the left hand unit has an under-voltage release coil a and the right hand unit has an earth leakage coil c and test switch 35.

Title: Improvements relating to phase sense indicators
Inventor: JOHNSON ANTHONY BEVIS
IPC: G01R25/00
Filed: 1955-09-30
Abstract: 835,008. Phase-sense indication. SAUNDERS-ROE Ltd. Oct. 1, 1956 [Sept. 30, 1955], No. 27952/55. Class 37. [Also in Group XL (c)] A circuit determining the sense of the phase difference between two square waves of the same frequency having equal mark and space durations comprises means for deriving from one wave sharp pulses corresponding to similar ends of each distinct mark excursion thereof, and an indicator device receiving the sharp pulses as one input and the remaining wave aa the other input which operates to give a visual indication of the occurrence of a sharp pulse within the mark or within the space excursions of the other wave. In Fig. 1 wave A is differentiated by resistance-capacitance circuit 12, 13 to a train of alternatively positive and negative going peaks corresponding to the beginning and end of each space excursion which are applied to the vertical plates of a cathode-ray oscillograph 10, whose horizontal plates are excited by wave B, in such sense that a positive vertical excursion at the right of the display and a negative excursion at the left thereof or vice versa are produced as the positive peaks occur during mark or space of the B wave; i.e. as A leads or lags B. Either the positive or the negative peaks may be suppressed so that the phase sense may be determined by reference to the side of the display at which a vertical deflection occurs. In Fig. 2 the control grid of a pentode 20 receives the differentiated peaks of the A wave while its suppressor grid receives the B wave directly, and the screen and anode are respectively energized from a positive source over resistances 26, 35 and connected over gas discharge .tubes 30, 40 to sliders of potentiometers 31, 41 between positive and earth; the pentode being biased to cut off in absence of positive inputs, and the potentiometers being adjusted so that coincidence between a B mark pulse and a positive differentiated A peak causes anode current to flow and the voltage drop across 26 to flash tube 30, while coincidence between a B space pulse and a positive A peak cause screen current to flow and the voltage drop across 35 to flash tube 40; thus indicating A leading B or B leading A. Specification 756,444 is referred to.

Kinematograph apparatus. - Apparatus for taking a series of photographs of a moving subject comprises means for intermittently rotating the camera so that its field continues to include the subject, means for taking one or more photographs in each position of the camera, and means for subsequently returning the camera to its initial position. A cam 50, Fig. 5, is adapted to rotate the socket 54 into which a stem 57 projecting from the underside of the camera 10 is inserted. A spring 60 effects the automatic return of the camera to its initial position. The camera mechanism is operated by the rotation of a camera shaft 8 driven through bevel gearing 29 by the shaft 28, Fig. 5. A spindle 15 coupled to the motor 9 (shown in Fig. 2) has a sliding sleeve 21 normally held away from the shaft 28 by a spring 23 but having a clutch device 25 adapted to engage and drive it when brought into action by the bell-crank lever 36, 38, which is periodically operated by the cam 40. A tappet 42, 43, between the arm 38 and the cam 40 is moved up and down by a further cam 44 and rocking arm 46; when in the upper position the enlarged portion 42 causes the cam to operate the clutch, a series of exposures thus being made; when in the lower position, the narrow neck 43 makes the cam 40 ineffective, the cam 50 then rotating the camera to the next position. The cams 40, 44 and' 50 are driven by the motor 9 and are timed so that a desired number of exposures are made whilst the camera is at rest in each position. Automatic focussing is effected by a radial arm projecting from the lens mount and engaging between the arms of a fork fixed to the support 13. Movement of the camera causes rotation of the lens mount and adjusts the focus. Means are provided for switching on the motor by hand or by a coin-freed device and for automatically switching off when the cycle operations is completed. The mechanism may include means for automatically switching the lights into and out of circuit. The subject may control the operations by walking over switches which complete circuits operating stops or clutches adapted to delay further operations of the mechanism until the subject reaches the points in his path at which the switches are placed.
