Abstract: 1,223,585. Phase comparators; automatic phase control. INTERNATIONAL STANDARD ELECTRIC CORP. 18 Sept., 1969 [23 Sept., 1968], No. 45087/68. Heading H3A. An arrangement for synchronizing digital data comprises a phase comparator in which the incoming data signals are compared with local clock pulses to derive a first signal having a pulse width dependent on the phase difference, and a second signal having a pulse width equal to one clock period and in which these two signals are then combined to provide a signal for adjusting the bias voltage. As described, the data signal is transferred through the shift register SR1 . . . SRN by the clock signal CP. The output from stage SR1 is gated at G1 with the input signal to produce the variable pulse-width signal and the output from SR1 and SR2 are gated at G2 to produce the constant pulse-width signal. These two signals are then combined at X to produce a variable bias which adjust a time constant circuit in the clock generator T1, T2 to vary its frequency.

Title: Improvements in and relating to a device for regulating a fuel injection pump for an internal combustion engine as a function of the depression prevailing in the induction pipe
IPC: F02D1/06
Filed: 1965-11-01
Abstract: 1,116,003. Regulating I. C. engines. LA PUBLICITE FRANCAISE. Nov. 1, 1965 [Feb. 9, 1965], No.46211/65. Heading F1B. A fuel injection pump regulating device comprises a diaphragm 10 actuating the pump control rod 16, a chamber V 1  communicating through a first aperture 4 with a Venturi 2 in the induction pipe 1 and through a second aperture 7 with the pipe downstream of the Venturi, the first aperture 4 being wholly on the downstream side of the throttle 3 during idling, at least a part of it being upstream of the trailing edge of throttle when the latter is beyond the idling position and being wholly upstream of the trailing edge of the throttle when the throttle is fully open. Operation: As the engine is started with the throttle 3 in the idling position the suction in pipes 6 and 8 is high and at a level corresponding to that prevailing in induction pipe 1. Diaphragm 10 exerts a strong force on springs 22 and 23 and thereby moving pivoted lever 14 until clearance X is great corresponding to a small fuel flow. When the throttle is partly open in position 3a part of aperture 4 is upstream of the throttle and the pressure in pipe 8 and chamber V 1  is slightly reduced thereby increasing the fuel supply. In the fully-open throttle position 3b the maximum pressure difference between pipe 8 and pipe 1 prevails thereby further increasing the fuel supply An extra pipe 6a leading to the second aperture 7 compensates the fuel delivery for the decrease in the cylinder filling co-efficient under full load conditions by reducing the suction in pipe 8 to a value intermediate those measured at 4 and 7. Changes in ambient pressure are compensated for by the interconnection of chambers V 2  and V 3  which are filled with air at standard pressure and temperature conditions. Chamber V 4  is open to ambient pressure and changes in pressure acting on diaphragm 27 result in corresponding changes in the pressure acting on diaphragm 10 thereby varying the fuel flow. The correction of fuel flow due to temperature changes acting on chamber V 3  is weaker because chamber V 3  is deformable.

Title: Annealing bent glass
IPC: C03B29/08
Filed: 1965-11-02
Abstract: <PICT:1059610/C1/1> A method of annealing bent glass sheets, wherein a glass sheet has been heated to a non-uniform temperature above the annealing range and then shaped to a desired non-uniform configuration while heat-softened, comprises cooling the bent glass sheet at a non-uniform, rapid rate from the non-uniform temperature to the top of the annealing range by exposing the more sharply bent regions of the sheet to blasts of strong cold fluid at a temperature substantially below the strain point while the less sharply bent regions are exposed to ambient temperature above the strain point, then exposing the entire sheet to a flow of fluid at a temperature slightly below the glass temperature and ranging from slightly above to slightly below the strain point until the glass is cooled to substantially the strain point to cool the sheet at a slow rate through the annealing zone. A glass sheet 28 supported on an outline mould, of different thermal capacity from the glass, and of non-uniform concave curvature, is first passed through a heating chamber (12) wherein it is brought to its softening point and bent to the shape of the mould.  Auxiliary crease heaters apply extra heat to the ends of the sheet to form the sharply bent regions.  The sheet on its mould is then transferred by the roller conveyer (8), (25), (34) to the cooling lehr which structurally is a continuation of the heating chamber. In the first part of the lehr, burners 35 depend through its roof 40 to direct jets of cooling, but combusted, gases on to the upper surfaces of the sharply bent regions of the sheet. Similar burners 36, 37 in the side walls direct a similar gas on to the under-surface of the sheet.  Cooling gas is only supplied from above until the sheet is at the top of its annealing range.  The central part of the sheet is cooled at this time to a lesser extent by the gases flowing away from the sharply bent regions. Thereafter, burners are only positioned in the sides of the lehr and are so regulated as to slowly cool the sheet through its annealing range.

This rocking is effected by a cam 29 mounted on a manually rotated shaft 28 coaxial with the setting means, motion being transmitted from the cam through a roller 24 and pitman 22 to the printing frame. The type is inked by a roller 25 that is carried by an arm 25<1> and is moved at the end of each operation from engagement with a cylinder 26 in an ink bath 27 to engagement with the type, by the abutment with the arm 25<1> of a stud 22<11> on the pitman 22.

Upon the upward rocking of the frame to make an impression, the drawer is released to the opening action of springs and operates a bell. The Provisional Specification states that the machine may be provided with a totalizer.
