Abstract: 987,990. Tables; folding underframes. QUAKER STRETCHER CO. June 29, 1961 [June 30, 1960; Aug. 12, 1960; Jan. 30, 1961], No. 23601/61. Headings A4H and A4W. The X-frames of a table, Fig 24, can be folded together to form a stand, Fig 23, capable of supporting a number of folded tables having tops 324. Table top 368 is disengageably connected by clips 370 to the cross-pieces of the X-frames. Bar 362 stays the frames in the open position when the top 368 is not in place. The bar also acts as a stop in the folded position. In a modification (Figs. 1-9, not shown), the upper part of the longer frame 332 is bent parallel to supporting arm 350 in the folded position, and the table top 368 is permanently pivotally attached to frame 332 at the position of cross-bar 372, which is omitted. The table may be further modified (Figs. 16-18, not shown) to stand vertically when folded and have a non-integrally formed handle 336. In another form, Fig. 11, the folded tables 130 are supported on a cranked portion of the longer frame 166 and the table top 186 is detachably carried on the reverse side of frame 166. In a further symmetrical form, Fig. 19, both frames are cranked to provide a saddle in which the folded table can hang. Two table tops 186b and 212 are detachably mounted on crossbars.

Title: Improvements in chucks providing a speedy clamping and centering
IPC: B23B31/163
Filed: 1952-09-22
Abstract: 712,079. Chucks. PASTORI, V. Sept. 22, 1952 [Sept 22, 1951], No. 23763/52. Class 83 (3) A scroll-plate chuck has a casing 6, 19, rigidly fixed to the machine tool, and a central member 1 and scroll plate 3 rotatable in the casing on ball bearings 7, 15, the central member being connected to the machine spindle. A pair of diametrically-opposite spindles 11 on an annular ring 5 each carry a pair of planet pinions 9, 10, the pinions 9 meshing with teeth 4 on the scroll plate and with a fixed sunwheel 12 and the pinions 10 meshing with teeth 8 on the central member 1 and with a sunwheel 13 which is adjustable by a hand lever, (not shown), and worm gearing 16, 14. On rotation of the central member 1, and with it the jaw-carrying member 2, the planet pinions rotate on their spindles and also round the chuck axis, thus rotating the scroll-plate at the same speed as the machine spindle but adjustment of the jaws can be made during rotation of the chuck by rotating the sunwheel 13 one way or the other by the hand lever. The spindles 11 have lubricating ports 18 and carry the pinions by loose rings which also have lubricating ports and are preferably made of nitrided steel. Ducts such as 17, 23, 24 and 25 are provided for lubricating other parts and felt packings 21 ensure oil tightness.
Patent GB-1258327-A (GB)
IPC: F23N5/12
Filed: 1969-05-09
Abstract: 1,258,327. Controlling burners. MULLARD Ltd. 9 May, 1969, No. 23763/69. Heading F4T. Gas monitoring and controlling apparatus comprises a solenoid operable gas valve V which, when opened, allows a stream of gas to pass to a burner B, said solenoid being energizable by a current flowing through a semi-conductor switch SCR when the switch is triggered, ignition of the gas producing an ionization current which allows the switch SCR to be triggered, whilst in the absence of flame, after an initial finite time period to allow ignition of the gas, the switch is prevented from being triggered, thereby closing the valve V and cutting off the gas supply. The solenoid of valve V is energized if triggering of the switch SCR takes place before 90 degrees of each positive half-cycle when an A.C. voltage is connected across L and N, and a phase advance circuit formed by capacitor C3 and resistors R6 and R7 ensures that the current applied to the trigger electrode of switch SCR, which may be a thyristor or a triac, is 90 degrees advanced with respect to its anode voltage. Three npn transistors TR1, TR2, TR3 are connected in cascade such that when TR1 is conducting, TR2 and TR3 are respectively non- conducting and conducting, and vice versa, and SCR is only triggered when TR3 is non-conducting. On applying the A.C. voltage, SCR is triggered at the beginning of the first positive half-cycle, thus opening valve V and initiating gas flow. The presence of capacitor C1 renders TR1 initially non-conducting, but as C1 becomes charged, TR1 begins to conduct and thus divert current from the base of TR2, which therefore does not conduct until progressively later in each positive half-cycle. Thus SCR is not triggered until later in the half-cycle, allowing a capacitor C4 to first of all charge, and then discharge through SCR when this triggers. This discharge through a transformer T causes a spark between the ignition electrode I and the burner B. If the gas ignites, the resulting ionization current flows by way of a monitoring electrode M and resistor R3 to the base of TR1. This current is phase retarded by a capacitor C2 such that it opposes the bias current to TR1 during the first part of a positive half-cycle, thus allowing SCR to be triggered in this period. In this way, when the gas is ignited valve V is kept open and since capacitor C4 does not charge, no spark occurs. If the gas does not ignite, or if the flame is extinguished, C1 charges, rendering TR1 fully conducting and TR2 non-conducting. Thus, SCR fails to trigger, the valve V closes and the system becomes "locked out". The sequence may be re-started either by briefly disconnecting the A.C. supply, or by discharging C1 through a switch placed in parallel with it.

Title: Improvements relating to apparatus for measuring liquid or quasiliquid materials
IPC: G01F3/38
Filed: 1934-08-18
Abstract: 442,948. Control of motors. JORGENSEN, M. VOGEL-, 24, B³lowsvej, Frederiksberg, near Copenhagen. Aug. 18, 1934, No. 23898. [Class 38 (iii)] [See also Groups XVIII and XXIX] Travelling between predetermined limits.- Apparatus for measuring liquid or semi-liquid materials includes a measuring vessel 1 provided with a discharge opening 4 controlled by a plug 5 actuated by an electric motor. With the form of apparatus shown in Fig. 1, when a measurement is to be taken a switch 35 at a remote control point is closed. This energizes a relay 36 which closes circuits from the source of supply 34 to a reversible motor 13 and electromagnets 14, the latter releasing a band brake 18 from a drum 12 which is driven by the motor 13 to unwind a cable and allow the descent of a rod 6 carrying the plug 5. A projection 20 on the rod engages an arm 22 of a switch so that as the opening 3 is closed the circuit of the relay 36 is broken, the motor is stopped, and the brake band is tightened. Also a circuit through a relay 37 is closed except for a mercury switch 10. When the measuring vessel is filled, the liquid overflows on to a projection 8 and tilts the mercury switches. This closes the circuit through the relay 37 which starts the motor in the reverse direction to raise the plug 5. The motor is stopped when a projection 21 on the rod 6 engages the arm 22. In a modified arrangement, Fig. 2 (not shown), continuous measurement of the amount of liquid flowing is possible by using two measuring vessels which are filled and emptied alternately, under the control of plugs actuated each by its own motor.

Abstract: 1,015,682. Reversible motion-picture film magazines. EASTMAN KODAK CO. June 22, 1962 [June 23, 1961], No. 24049/62. Heading G2E. In a reversible motion picture film magazine of the kind shown and comprising a housing 11 enclosing a film supply core 12, a film take-up core 13 and a film strip 14 connected to the cores at opposite ends thereof with the major portion of the film strip initially wound upon the supply core, the proper exposure of the film being effected by first loading the magazine into a motion picture camera in a first position in which the film is transferred by film advancing means within the camera from the supply core to the take-up core and, after nearly all the film has been so transferred, by reloading the magazine into the camera in a reversed position in which the film therein is then transferred from the take-up core back to the supply core, said housing includes means defining an indicating position at which an area of the film is visible from the exterior of the housing and the film strip includes indicating means so located as to be brought into view at the indicating position in the event that the magazine is initially improperly loaded into a motion picture camera in the second reversed position and the film therein is advanced towards the supply core, first means for stopping the movement of the film when the indicating means is at the indicating position and second means spaced from the first means for stopping the movement of the film before the indicating means is at the indicating position when the film has been properly exposed. An exposure aperture may be utilized for the said indicating position. In the illustrated embodiment, both apertures 25 and 28 are so used. A preferred form of film, as shown in Fig. 3, comprises perforations 21 which are initially visible through apertures 25 and 28 and serve to indicate that the film is completely unexposed and also comprises perforations 22 (said indicating means) which become visible (as shown in Fig. 6) if the magazine is inserted in a camera wrong side first. The perforated side edges of the film include a slot 20 (said first means) whereby-in the event of such wrong insertion-the feed claw 23 in the camera becomes ineffective before the leading end 15 of the film is torn or pulled off the core 13. Slots 18 and 19 (said second means) are provided for similarly terminating film feed after proper exposure of each longitudinal half of the film respectively. Instead of slots 18-20, imperforate portions of the film may be provided. A shutter member may be provided which normally covers the exposure apertures and which would be moved aside for viewing the film

Title: Improved variable lifting surface for aircraft
IPC: B64C3/54
Filed: 1939-08-21
Abstract: 580,521. Aircraft with variable lifting surfaces. GERIN, J. Aug. 21, 1939, No. 24065. Convention date, Aug. 29, 1938. [Class 4] A variable area wing or other surface of an aircraft comprises a fixed framework on which a rigid section constituting a high-speed surface can move towards or away from the fuselage, a flexible surface, connected to the root of the rigid section, being paid out or wound on a drum as the rigid section moves along the fixed framework. The ailerons remain operative in both the extended and retracted positions of the wings. A plane 3 is guided by rollers on a beam 1 extending across the aircraft and its root normally closes a hole in the side of the fuselage. Attached to the root is a flexible covering supported at intervals by ribs 22, Fig. 11, and normally collapsed and stowed within the fuselage upon a roller. As the plane 3 is moved outwards by an endless chain, the ribs 22 are moved, by projections on the chain, along the lower flange of the beam 1, being guided by the clips shown. The ribs 22 have extensions 22a. The upper surface of the flexible covering is supported by hinged members 24, 25 which move in guides 27 on an upper plate 28 hinged to the beam at the root and capable of being raised, as the plane 3 is moved outwards, to act as a bridge between the rigid and flexible parts and also to complete the upper surface. Additional ribs 29 form a slat on the leading edge, both ribs 24, 29 being raised by a lever 31 and a rubber spring 33. The endless chain is driven through worm gear by an electromotor which simultaneously drives the drum. The drum is .connected to its shaft by a flat spiral spring to compensate for variation in diameter as the flexible material with its ribs is wound on or off. The wings 3 carry ailerons 21, Fig. 15, actuated by the cable system shown. An aileron lever 47 is connected by cables passed over pulleys 48, 48a, mounted on the wing 3, over fixed pulleys 49, 49a, pulleys 50, 50a movable by the pilot's control, fixed pulleys 51, 51a and 52, 52a and finally -anchored at 53, 53a to the opposite wing 3. Consequently, the effective length of the cable is unaffected as the planes 3 move. A modification involving fewer pulleys also is described.
