Title: Apparatus for stacking sheets
IPC: B65H29/14
Filed: 1970-05-29
Abstract: 1298859 Delivering sheets into a stack INGENIEURSBUREAU DE RIDDER NV 29 May 1970 [30 June 1969] 25907/70 Heading B8R In an apparatus for stacking sheets 5 of paper, e.g. supplied in an overlapping stream, means, e.g. lower and upper endless belts 3, 4 are provided for feeding the sheets to a stack forming means including a stop member 85, a sloping guide member 86, and lifting means including a star wheel 90 for lifting the leading edges of each sheet to a stack 96, the star wheel also serving to support the stack. The leading edge of each sheet engages the upwardly curved guide 86 and stop member 85 and is lifted by two star wheels 90 rotated via a free-wheel clutch, which facilitates adjustment, to the bottom of the stack 96, the trailing edge of each sheet being raised by teeth on the outside of belt 4 which project through a slot in a stack backplate 68 at a belt return pulley 64. The forming stack is thus supported on the teeth of belt 4 and by rollers on each of the projections on the rotating star wheels 90 and is located between side-plates 83 and the backing-plate 68. Adjustable auxiliary side-belts 30 adjacent to, but slanting downwardly of the belt 3, co-operate with belts 81 and rollers 79 at the sides of belt 4 to bend each sheet longitudinally to stiffen it. Belts 3 and 4 are each mounted on a frame 22, 42, respectively, which are longitudinally adjustable relative to each other so that the stack backing-plate 68 mounted on frame 42 can be adjusted for stacking sheets of different lengths. The top frame 42 can be pivoted about a shaft 53 and thus allows for feeding sheets of different thicknesses. When a predetermined number of sheets have been fed, a counter 41 activates a dog clutch causing struts 26, 27, 45, which support the frames 22, 42, to be pivoted about their shafts 28, 29 by an eccentric 37 and lever 36 so that the frames are moved forwards thereby urging the stack towards the tip (101), Fig. 2 (not shown), of a parting finger 98 pivotable about a shaft 100. The finger engages a guide track (110), Fig. 3 (not shown), on frame 22 which raises it into engagement with the bottom of the stack, an endless belt 102 on the finger then moving the stack on to removal belts 111, (124). The top of the forming stack may be engaged by a pressure roller 125 and as soon as frames 22, 42 move forward at the beginning of a stack removal cycle, an electromagnetic clutch 135 on a shaft 136 in a stationary machine frame clamps a plate 134 to a lever 152 so that tension applied by the moving frame member 156 to spring 157 is transmitted by lever 152 to a parallel motion linkage 137, 130, 133, 127 causing an endless belt 142 associated with roller 125 to press on to the top of the stack to aid its removal.

Title: Improvements in or relating to flat glass
IPC: C03C21/00
Filed: 1964-06-23
Abstract: Flat glass which has been manufactured in ribbon form on a bath of molten tin is treated by contacting the glass surface which has been in contact with the molten tin with a gaseous halogen reagent for a sufficient time and at a sufficient temperature to render harmless those harmful impurities which have entered the glass surface as a result of its contact with the molten tin.  The glass ribbon is preferably passed through a zone containing the gaseous halogen, e.g. chlorine or hydrogen chloride gas, at the beginning of the annealing lehr.  Alternatively the zone may comprise a melt of a metal halide e.g. zinc chloride having a vapour pressure of 1 mm., an atmosphere of nitrogen being maintained above the melt.  The glass surface is presented to the gaseous halogen for a time of from one to five minutes at temperatures of from 400 DEG  to 600 DEG  C.  The film of zinc chloride found on the glass is washed off with hot water.

Abstract: 1,268,640. Acoustic detection of gas bubbles in blood. NATIONAL RESEARCH DEVELOPMENT CORP. 29 May, 1969 [31 May, 1968], No. 26072/68. Heading H4D. Apparatus for detecting decompression bubbles in a diver's blood comprises a transducer for application to his skin to transmit an acoustic wave of predetermined frequency through the blood, and acoustic detection means tuned to respond to acoustic waves of a related frequency generated in the blood due to non-linearity of its acoustic propagation characteristics. In one arrangement, a transmitting transducer coupled to the liquid is energized by an oscillator via an amplifier and a narrow-band filter tuned to the oscillator fundamental frequency. The same or a spaced separate skincontacting transducer is used as a receiver and is connected to an amplifier and amplitudeindicating device via a filter tuned to a harmonic (e.g. the second) or sub-harmonic of the transmitted frequency. The amplitude of the received acoustic signal at the fundamental frequency may additionally be monitored. Spurious pick-up at the desired harmonic or sub-harmonic frequency, due to non-linearity of the transducer or transducers, can be cancelled by initial adjustment of a phase-shifter and attenuator connected across the transmitter filter, the transducer(s) being arranged in air or applied to a person with bubble-free blood. In a modification the transmitted acoustic signal has two distinct frequency components and the receiver arrangement is tuned to detect the sum or difference frequency generated by the non-linearity.

Abstract: 1304157 Digital to analogue converters SINGER CO 19 April 1971 [4 June 1970] 26948/71 Heading G4H In a digital to analogue converter where a reference voltage is integrated for a length of time dependent upon the magnitude of the digital input, changes in circuit parameters, particularly of the integrater, are compensated by integrating (for a predetermined time) a voltage equal to the analogue output voltage which should drive the output of the integrator to zero if there had been no parameter changes, otherwise an error voltage remains which is algebraically added to the result of the next integration of the digital input to produce a corrected analogue output. In the arrangement of Fig. 1 digital data is held in a register 14 and gated into a counter 32, which counts down by pulses from clock 30. The compliment could be put in the counter which is then counted up. Program register 34 via line 81 enables gates 21, 23 for the period of counting, only one gate being opened by flip-flop 18, according to the polarity of the digital data, to open gate 51 or 54. A positive or negative reference voltage +E or -E is thereby fed to integrator 63 for a period of time dependent upon the digital data. The program register then transfers the integrator output via gate 70 to capacitor 47 and via buffer amplifier 48 to converter output 49. The voltage at 49 is then fed back via gate 57 to be integrated for a predetermined period. Any voltage at the integrator output 65 remaining after this period is algebraically added to the next integration of the reference voltage. In another arrangement (Fig. 3, not shown) two such converters each convert six bits of a 12-bit number, the two analogue outputs being added.
