Title: Improvements in and relating to apparatus for indicating the speed and/or distance travelled by a ship through water or aircraft through the air
IPC: G01P5/16
Filed: 1930-06-04
Abstract: 353,994. Pitot-tube apparatus. DRYSDALE, C. V., Admiralty, Whitehall, London. June 4, 1930, No. 17271. [Class 69 (i).] In Pitot-tube apparatus of the kind wherein the difference of pressure between the orifices is utilized to operate a member which generates a balancing pressure centrifugally, a diaphragm actuates a member which operates a relay controlling a variable speed device which regulates the centrifugal device. In one form, opposite sides of a diaphragm 2, Fig. 1, are in communication, through pipes 16, 17, with the static and pressure orifices ; movement of the diaphragm actuates the piston valve 5 of a liquid pressure system to displace a piston 53, Fig. 8. A rocker 52 carrying two additional brushes 50 of a constantly running dynamoelectric machine 49 which are connected to pairs of diametrically arranged brushes 56, 57 of a motor 58, is thus rotated, to produce rotation of the fan 12, the speed and number of revolutions of the motor 58 each being recorded on one or a number of devices. A centrifugal governor may be arranged to take the place of the fan 12. In another form, the centrifugal device comprises three rotatable concentric cups 25, 26, 27, Fig. 3, the edge of the cup 26 serving as a diaphragm while the space 35 between the cups 25, 26 is filled with mercury. A float 34 controls the position of the piston valve 5. The device shown in Fig. 6 is disposed between the Pitot-head and the diaphragm chamber ; the level of the line of separation between the water and oil being observed and regulated in the concentric reservoirs 39, 40, two-way cocks 45, 46 being provided together with oil containers 41, 42. Air traps 37, 38, and a double two-way cock 47, which may be operated to allow water at high pressure to be discharged through the Pitot-head, are also furnished. Specification 349,930, [Group XXXVII], is referred to.

Title: Improvements in or relating to ultrasonic detection apparatus more particularly for diagnostic application
Inventor: BROWN THOMAS GRAHAM
IPC: G01S15/18
Filed: 1967-04-14
Abstract: 1,212,349. Ultrasonic inspection devices; diode gating circuits. T. G. BROWN. 16 April, 1968 [14 April, 1967], No. 17304/67. Headings H3P and H4D. In a pulse-echo system for the ultrasonic examination of an object a transducer probe capable of translational movements along three co-ordinate axes and of rotation about two axes is scanned over the object and echo signals are gated so that only those arising from reflection at a particular internal plane section of the object are displayed on a cathode-ray tube. In the Fig. 3 embodiment probe 10 is mounted for translational movement along axes X, Y, Z and rotational movement about two mutually orthogonal axes (one of which is parallel to a translational axis). Signals representing the X, Y and Z eo-ordinates of the probe are derived from translational X, Y and Z resolvers 35, 31, 33 and rotational resolvers (sine/cosine potentiometers) 36, 37, and are applied to timebase generators 51, 52, 53 respectively. For displaying a cross-section of the object parallel to the XY plane the signals representing the X and Y co-ordinates of the probe control the sweep amplitudes for the X and Y deflections of cathode-ray tube (C.R.T.) 58, and the Z signal is compared in coincidence detector 59 with a preset signal V from 60 representing a predetermined range z from which echoes are to be displayed. If the z signal lies between V and V + #V coincidence detector 59 opens gate 55 to pass echo signals to the beam intensity control circuit of C.R.T. 58. Cross-sections parallel to the XZ or YZ planes may be displayed by supplying coincidence detector 59 with the Y or X signal instead of the Z signal, the C.R.T. sweeps being controlled by the X and Z or Y and Z signals. Two or more crosssections in parallel or non-parallel planes may be displayed simultaneously by providing a different C.R.T. and associated coincidence detector for each cross-section. Co-ordinate transformation circuits may be connected between time base generators 51, 52, 53 and deflection amplifiers and coincidence circuit 56, 57, 59 for displaying cross-sections in skew planes. Prior art scanning and display systems, including a stereoscopic display system, are discussed. Gating circuits (Fig. 5).-An AND gate comprising diodes 77, 78, 79 passes echo signals from buffer amplifier 79a to C.R.T. 58 only when the outputs of both differential amplifiers 75, 76 are negative. Each differentiated amplifier is arranged to provide a negative output when the voltage at its upper input is more positive than the voltage at its lower input. Potentiometer 60 provides a voltage V for the lower input of amplifier 76. Network 71, 72, 73 provides a voltage #V so that the voltage on the upper input of amplifier 75 is V + #V. The other inputs of the differential amplifiers are supplied with the Z signal, so that both amplifier outputs will be negative only when the Z signal lies between V and V + #V.

[Class 38 (iii)] [Also in Group XXXV] In a synchronized drive for printing presses according to the parent Specification, indicating asynchronous machines 9 coupled to the different units have their rotors arranged to be connected in series with each other and with a relay 8 which relay operates when the current passing through it falls to zero or a minimum value to effect the interconnection of the rotors of the synchronizing machines 10. Thus the mutual positioning of the units is correctly attained. Upon closure of a switch 12 the relay 8 is connected in series between the rotors of the machines 9 of the left section 2 and the folder 3, and the relay 8 operates to energize an auxiliary relay 4. This relay 4 operates to start the driving motor 1 of the left section. When the section 2 driven by the motor 1 attains the correct position in relation to the folder 3 the relay 8 is deenergized and the relay 4 drops out to complete a circuit for a switch 14 which interconnects the rotors of the synchronizing motors 10 of the left unit 2 and the folder 3. Similar control effects the interconnection of the machines 10 of the other units 2. The indicating machines 9 may be geared to their units.

Title: Improvements in or relating to labelling machines
Inventor: KRONSEDER HERMANN
IPC: B65C9/40
Filed: 1969-04-03
Abstract: 1,260,931. Label detecting machine. H. KRONSEDER. 3 April, 1969 [4 April, 1968], No. 17660/69. Heading B8F. At the exit from the labelling region of a machine a photo-electric device (5), Fig. 1, not reproduced, receives light directed from a source (4) on to the labelling zones of passing articles (2), the electrical response resulting from detection of an unlabelled article actuating a control circuit that separates labelled and unlabelled articles. The photo-electric cell (5) may receive light either by reflection from or transmission through a passing article, and the output line from the photo-electric cell (5) is completed and broken by a cam-operated switch (8) in synchronism with the passage of articles. Articles 2 (Fig. 2) are transferred from the labelling region to a starwheel 3 by a rotating table 1. In a first embodiment, a labelled article 2 is guided by the counterclockwise rotating starwheel 3 to the position 2<SP>1</SP>, whereupon a lever 9 rotating with the starwheel pivots about an axis 21 under the action of a non-rotating cam 23 and pulley 22, to restrain the article (lever in broken line position) while it passes over a conveyer belt 16, and to release the article (lever in full line position) on to a conveyer 10. When an unlabelled article reaches position 2<SP>1</SP> a solenoid 15, activated by a delayed signal produced as the article passed the photo-electric cell, causes a pulley 15<SP>1</SP> to obstruct lever arm 20 and prevent the lever 9 from taking up a restraining position, so that the article is carried away by conveyer 16. In an alternative embodiment (Fig. 3, not reproduced) a pivoted guide arm (24) is mounted between the conveyers 10, 16 and under the action, as described above, of a solenoid guides unlabelled articles on to the required conveyer. Guiding may be carried out by suction pads 25 (Fig. 5) fed by a vacuum pump 33 via conduits 26-29. The suction pad 25 is opened to the conduits by a slide valve 30 operated by a non-rotating cam 31 and spring 32, and the conduits opened to the vacuum pump by a solenoid operated valve 15<SP>11</SP> (the cam and solenoid action can be interchanged). Articles can be released over the required conveyer by applying and removing suction at the appropriate time. A visual or audio alarm may additionally be operated from the photo-cell to indicate one or more unlabelled articles, and gating devices may automatically stop or slow down the labelling machine after the passage of a predetermined number of unlabelled articles. The machine has infinitely variable speed driving mechanism.

Abstract: 887,873. Load-handling machines. BENFORD Ltd. Aug. 19, 1960 [May 25, 1959], No. 17775/59. Addition to 837,043. Class 78 (3). [Also in Group XVIII] The invention of the parent Specification, which is essentially a tiltable loading skip so mounted (by a connecting-means between the skip and the associated apparatus and by an extensible strut) that in its lower, loading position it is constrained to a limited translatory rising and falling movement whereby it bears on a weighing device, is modified in that the connecting means comprises a guide 14, connected to the apparatus 11 (e.g. a concrete mixer) and a guide-engaging member 20 which is connected to the skip 24 and is movable along the guide for a distance such as to allow the upward movement of the skip to bring its upper end level with the receiving opening 17 of the concrete mixer preparatory to tilting movement of the skip to discharge the material therefrom. This arrange. ment enables the drum of the concrete mixer to be mounted at a greater height above the base 12. The extensible strut is telescopic, comprising inner and outer members 25, 26, either a rod and tube or a rod and channel. The outer member may have openings for the expulsion of cementitious or other material that may have become lodged therein ; or, alternatively, the outer member may be a sideways-facing channel and the inner member may have an inclined end face which displaces the cementitious material. In its lower position a projection 32 from the skip bears on a weighing device 31, e.g. an hydraulic capsule, as in the parent Specification. The skip is elevated by an hydraulic ram 29 and a guide-engaging roller 20 follows a guide 14 on each side. Near their tops the guides 14 incline towards the opening 17, and when the rollers 20 reach the tops of the guides the skip pivots about their axes towards the opening 17, the weight of the skip then being taken on plates 19 at the top ends of the guides which have arcuate upper surfaces on which trunnions, projecting from the skip and preferably equipped with rollers, can move. There may be a shoot between the drum and the skip and the hydraulic capsule may be connected to a pressure gauge.
