Patent GB-215005-A (GB)
Abstract: 215,005. Tiranty, P. H. L., and Conti, J. T. F. April 25, 1923, [Convention date]. Ink-ribbon mechanism. -In a machine for franking letters &c. comprising a depressible casing 1 containing stamping and counting- mechanisms, inking is effected by an ink-ribbon 46 wound on spools 51, 52 on the casing and passing over guide-rollers 47 - - 50 on the casing. Pawls 56, 57 co-operating with ratchet-wheels 53, 54 on the spools are mounted on a lever 55 which is pivoted on the casing and cooperates with one or other of two abutments 63, 64 carried by levers 60, 61 which are pivoted on the stationary base, and are connected by a link 62 engaging a spring-catch 90. When the casing descends, the lever is rocked by one of the abutments, one of the pawls remains in engagement with its ratchet-wheel, and a spring 65 on the lever is flexed. On return of the casing, the spring rocks the lever, and the operative pawl turns its ratchet-wheel. Reversal of the feed is effected by rocking the levers 60, 61, and thereby substituting one abutment for the other. The levers may be rocked by means of a knob 70 on the link 62, or by means of automatic mechanism comprising a spring-urged lever engaging the link 62, and having pins cooperating with a rocking arm carrying rollers which rest on the ink-ribbon on the spools.

Title: Fuel injection system
IPC: F02M59/44
Filed: 1958-07-04
Abstract: 831,248. Regulating. ALLIS-CHALMERS MANUFACTURING CO. July 4, 1958 [July 9, 1957], No. 21578/58. Class 7(6) [Also in Group XXXI] In a tractor having an engine driven hydraulic. pump 27 for actuating a power tool such as a bucket shovel 13, the fuelinjection pump control rod 61, Fig. 1, is controlled by a centrifugal governor 39 and a manual control lever 64, and means 82 responsive to the output pressure of the hydraulic pump 27 permit an increase in the fuel supply beyond the normal full load supply when a predetermined load on the tool is exceeded. The bucket 13 is lifted by hydraulic rams 14. Under normal conditions the maximum fuel supply is determined by a stop 72 limiting the movement of a lever 56 connected to the control rod 61 and actuated by the governor 39 and manual control lever 64. Under overload conditions, i.e. when the engine is moving the tractor forward and simultaneously lifting the loaded bucket 13, the pressure developed in the hydraulic system is sufficient to force back a plunger 109 which moves the stop 72 to the left to permit the control rod 61 to move beyond the normal maximum supply position. The travel of the stop 72 is limited by an adjustable stop 112.

Title: Improvements relating to bolometers
IPC: G01J5/20
Filed: 1947-08-08
Abstract: 636,057. Power meters; resistance coatings and deposits; temperature variable resistances. BROOKLYN, POLYTECHNIC INSTITUTE OF. Aug. 8, 1947, No. 21847. Convention date, Oct. 23, 1945. [Class 37] In U.H.F. power measuring apparatus, Fig. 1, a bolometer forms a termination to a coaxial transmission line and one arm of a D.C. energized Wheatstone bridge and possesses a broad band response so that the apparatus may be used, for example, to measure the power output of a U.H.F. oscillator at different frequencies. In the bolometer the U.H.F. power absorbing and temperature-variable resistance element 7 is matched to the line characteristic impedance by quarter-wave line sections 8, 9, each of length substantially equal to one quarter of the mid-frequency wavelength. The end section 1b of the bolometer casing 1 is closed by a terminal cap 5 which is insulated from the casing 1 by a bushing 6 preferably made of polystyrene. The cap 5 and bushing 6 are so constructed that the dimension lengthwise 6a to 6b, is equal to one quarter of the midfrequency wavelength. A central conductor 3 in the bolometer is supported by a quarter-wave lateral section 3a and is provided with sockets at each end into which extend respectively the transmission line central conductor and the line matching section 9. The resistance element 7 designedly has minimum thermal lag and may be formed as a high resistance metallic film, for example platinum or an 'alloy of platinum and silver on a thin glass tube 7a, Fig. 2. The length of the resistance coating (shown b to c in Fig. 2) is preferably short in comparison with the wavelength of U.H.F. currents within the measuring range. In balancing the bridge on D.C., which is the initial operation with zero U.H.F. current, the path of the D.C. is through the cap 5, elements 7. 8, 9, 3a, and casing 1. Under conditions of U.H.F. wave reception the line section 1a, 3a presents an infinite impedance or open circuit so that no power is diverted and the bushing 6 provides a byepass condenser action or low impedance route for the U.H.F. currents to the element 7. The latter undergoes a change in resistance due to the heat generated by the highfrequency currents which effects bridge unbalance and the power transmitted and absorbed in element 7 may then be read on meter 13. Specification 583,238 is referred to.

Abstract: 1421445 Riveting GAASTRA BV 8 May 1973 [8 May 1972] 21906/73 Heading B3U [Also in Division F2] An eyelet is formed in sheet material 1, e.g. a sail cloth or tarpaulin, by applying a thermosetting adhesive to the frayed edge of a hole in the sheet 1 to form a raised rim 2, sandwiching the edge of the hole between two identical rings 3 surrounding a flanged tube 6, deforming the tube 6 around the rings 3 and allowing the adhesive to set. A stainless steel tube having a flanged lower end is positioned in a recess 9 of a die 7. Positioned against the flange of the tube is an aluminium ring 3 having a cutaway portion at its inner periphery (Fig. 3, not shown) for receiving the edge 2 of a hole in a sail cloth 1, which edge 2 has been frayed and coated with an epoxy glue. After placing an identical ring 3 on top of the sail cloth 1, a tapered portion 11 of a punch is moved through an opening 8 in the die 7 to cause a recess 14 in the punch to deform the tube into a collar 6 which clamps the rings 3 against the cloth 1. After unscrewing the upper part 10 of the punch from the lower portion 11, the die 7 is forced off the latter.
