Abstract: 1,273,048. Speed governors. USTAV PROVYZKUM MOTOROVYCH VOZIDEL. Sept. 19, 1969 [Sept. 26 1968], No.46317/69. Heading G3B. [Also in Division F1] In a rotary distributer type fuel injection pump the plunger stroke is limited by the prongs 14 of a bifurcated fork 12 which is axially movable under the influence of a centrifugal governor against the action of springs 1 and 2. The springs act between a nut 4 and the end of a casing 3 slidably mounted on the fork 12, and a spring-loaded tappet 11 is connected via member 7 and bearing 7a to the governor carrier. During starting a two armed manually operable lever 8 is positioned so that its first arm depresses the tappet 11 and its second arm acts on a further lever 13, Fig. 2 (not shown), thus moving the carrier, fork and casing to allow maximum plunger stroke but maintaining the spring-bias. During normal running lever 8 is rotatedÀso that its first arm acts on the lever 13 to maintain the position of the casing 3, and the weights 6 act on the fork 12 against the action of the springs 1, 2 to vary the plunger stroke in response to speed. To stop supply the lever 8 is moved to a neutral position in which it acts on neither tappet 11 nor lever 13; this allows a spring 10 to force lever 13 and thus the fork 12 to the extreme right.

Filed: 1967-10-12
Abstract: 1,166,175. Colour television tubes. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. 12 Oct., 1967 [15 Oct., 1966], No. 46628/67. Heading H1D. In a colour television tube having a substantially rectangular colour selection electrode-as shown, a shadow mask 3, Fig. 1-provided with an axially extending frame 4 around its edge, the electrode is supported by at least three supporting members 7 which are each secured to the periphery of the frame at points V which are nearer the tube screen 2 than the points R at which they are supported from the tube wall, whereby when the electrode expands upon heating its resultant displacement will have a component directed towards the screen, such as to reduce the mis-register, caused by the expansion, between the apertures in the electrode and the associated groups of colour elements on the screen. As shown, the shadow mask is provided with three supporting members 7, 7<SP>1</SP>, which at one end are welded to the support ring 4 of the electrode, and at the other end are supported by the engagement of their perforated ends 8 with the conical bosses 6. Upon expansion of the mask, the points V describe arcs of circles, such that the mask apertures are displaced by B and P 1  to give a resultant displacement P 2  lying on the line joining the mean deflection centre D of the electron beam and the associated group of colour elements on the screen. Since it is undesirable that the two supports 7 arranged one along each short side of the electrode, Fig. 3, should be located at the mid-points of those sides, the apertures at the top and bottom of the screen are displaced outwards by different distances C, E, the difference depending upon the distance between the line joining members 7 and the mid-line M of the electrode. This effect may be compensated by arranging the two members 7 to lie at an angle to a plane which is parallel to both the tube axis and the longer sides of the electrode (Fig. 2, not shown). The flange 5 of the electrode support ring 4 may be blackened on its surface remote from the screen, to enhance its effect as a cooling fin.

Abstract: 1291882 Apparatus for treating textiles KANEGAFUCHI BOSEKI KK 23 Sept 1969 [24 Sept 1968 (3)] 46728/69 Heading D1L [Also in Division G3] A method of controlling the temperature in a wet process of textile material which is processed in accordance with a predetermined trapezoidal programme (as defined in the Specification) comprises a device by which a control signal controlling the temperature and the process is held after the control signal has been removed' from the device, the signal being derived by an ON-OFF device from two signals, one of which is a signal from a trapezoidal programme generator and the other of which is a feedback signal, the feedback signal and the control signal into the holding device being sampled for predetermined periods so as to control the wet process and the temperature thereof. Thus a single programme generator can be used to control a plurality of wet processes. A wet process for the dyeing of a textile material 2 comprises placing the material into a dyeing bath I and adding various agents to the bath according to a predetermined programme and at the same time controlling the temperature of the bath according to the temperature required at each of the stages of the process. The agents to be added to the bath may be a pretreatment agent, a dyeing agent, a dyestuff agent; an additional agent and an aftertreatment agent, these agents being contained in supply baths 18-22 and the admission of these agents to the bath 1 being controlled by valves 23-27 which themselves are controlled according to the predetermined programme. During the dyeing process the liquid in the bath is circulated by a pump 3, the temperature of the liquid extracted from the bath being served by means of a sensor 9. The signal from the sensor 9 is compared with a signal from the trapezoidal programme generator representing the required temperature and the resulting signal is used to control valves 10, 12, the valve 10 admitting steam and the valve 12 cool water, to a heat exchanger 7 situated in the bath 1 so as to maintain the temperature of the fluid in the bath at the required value during each of the stages of the dyeing process. The bath is provided with valves 16, 17 for discharging the fluid therefrom and a discharge valve 14 and a trap 8 are associated with the heat exchanger 7. Fig. 9 (not shown) illustrates a number of dyeing processes controlled by a single trapezoidal programme generator.

Headings F1F and F1P. Synchronization of two reversible hydraulic motors 2, 3 suitable for actuating ship's stabilizers and connected in series with a reversible pump 1 is maintained by a fluid-pressure pulse generated by a piston mechanically linked by a lever to the leading motor e.g., piston 8 linked by 14 to motor 3 and which pulse is transmitted from a cylinder space 16 along a line 25 to lift a valve 26 in a branch line 27 of the pump delivery line 10 thereby admitting sufficient pressurized fluid to the inlet line 11 of motor 2 to advance the same. Motor 2 is linked by 13 to a piston 7 which when displaced to the right by virtue of anticlockwise movement of motor 2 and link 13 draws fluid into a cylinder chamber 15 from chamber 16 through line 25 and a non-return valve 22; the two motors being in unison. In the event of motor 3 lagging behind motor 2 during their anticlockwise rotation synchronization is not effected until the pump 1 has been reversed and motor 2 reaches its mid position during it rotation in a clockwise direction when motor 3 leads and displaces a piston 9 to the right which directs a pressure pulse to lift a valve 28 to relieve excess oil from line 11 to a return 24.

Abstract: 1530123 Analogue to digital converter; pulse frequency modulator LUCAS ELECTRICAL Ltd 21 Oct 1975 [1 Nov 1974] 47295/74 Headings H3H and H4L  Analogue voltage inputs to either or both inputs 111,110 vary the frequency of pulse train output of bi-stable 121, subsequently converted to digital by counter 135. An input voltage applied to 110 charges capacitor 120 via potential divider 113, 114 and op. amp. 118 to the voltage level on 111 detected at comparator 122. Bi-stable 121 changes state causing transistor 115 to conduct and the input to discharge capacitor 120 via potential divider 116, 117 and resistor 119 to a preset level detected at comparator 123. The frequency of the pulse train is thus dependent on the sawtooth shape (due to 110) and amplitude (due to 111). The pulse train is counted in 135 for a period due to input 139, which may derive from a further analogue input. The analogue inputs may be due to engine speed, manifold pressure or airflow &c.
