Title: Improvements in or relating to hydraulically-controlled concrete mixers
IPC: B28C5/18
Filed: 1957-10-17
Abstract: 818,880. Concrete mixers. ETABLISSEMENTS RICHIER. Oct. 17, 1957 [Oct. 18, 1956; April 16, 1957], No. 32436/57. Class 86 A concrete mixer has a loading skip, pivoted to the main frame, raised and lowered by a hydraulic ram working through a pivoted crank and link arrangement. In the embodiments described the ram is also associated with tilting of the mixing drum and, in one form, the skip 8 is pivoted to the frame at 14 and is connected to the cylinder 38 of the ram by a pivot 17, a link 33 and two cranks 34, 36 mounted on a shaft 35. The piston rod 39 of the ram carries a toothed rack 40 meshing with a pinion 53 on the drum cradle so that when pressure is applied to the ram the rack turns the drum from its unloading position to the loading position shown and, after a stop 52 abuts against the gear casing 51, the cylinder 38 is forced back so as to raise the skip and tip the contents into the drum. After mixing is complete the pressure fluid is withdrawn from the ram and the skip is lowered and, thereafter, the retraction of the rod 39 tilts the drum to its discharging position. In other forms the hydraulic cylinder has a piston at each end and movement of the upper piston causes tilting of the drum while relative movement of the cylinder and lower piston actuates the skip.

Abstract: 853,611. Dynamo - electric machines. ENGLISH ELECTRIC CO. Ltd. Nov. 9, 1956 [Nov. 5, 1955], No. 32625/55. Class 35 To permit relative movement and thereby avoid " copper shortening " resulting from different thermal expansions of a coil and its supporting core member in a dynamo-electric machine, the parts are separated by means comprising or including a solid electricallyinsulating material which exhibits a low coefficient of friction relatively to normal insulating materials such as glass-fabric, mica or asbestos. The low coefficient material is polytetrafluorethylene which is impregnated in or coated on one or both sides of various materials. Fig. 1 shows a turbo-alternator rotor solid cylindrical ferromagnetic core 12 in whose axial slots 11 are radially stacked copper winding conductors 10 separated from each other and from a damping winding 16 and slot wedges 13 by strips 18 and a member 17 respectively, both of P.T.F.E. impregnated asbestos. A slot lining trough 15 may be of either similar material or a conventional insulating material. In other similar embodiments, not shown, the member 17 is omitted but the damping winding is of P.T.F.E. impregnated copper, or in the case of a slotted stator the winding coil sides are wrapped externally with P.T.F.E. impregnated cloth. In Fig. 2 a layer 22 of P.T.F.E. impregnated asbestos is disposed between the outermost end winding conductor 20a of a rotor and an annular end member 21 which supports the end windings against centrifugal force. In Fig. 3 a salient pole rotor has winding interturn insulation 33 and an end insulating washer 32, all of P.T.F.E. impregnated asbestos, and in a modification the end washer may be of P.T.F.E. impregnated sintered steel.

Title: Improvements in or relating to automatic operation controllers
IPC: G05B19/14
Filed: 1948-12-17
Abstract: 688,614. Timed control of electric circuits. LINDARS, H. Dec. 19, 1949 [Dec. 17, 1948; Jan. 27, 1949], Nos. 32741/48 and 2338/49. [Drawings to Specification]. Class 118 (ii) [Also in Group XXXV] A single operation, or each of a number of sequential operations, say in a manufacturing process, is terminated upon a rotary stepping switch receiving a pre-selected number of electrical impulses from an impulse generator which furnishes pulses at "unit" rate whilst the operation is proceeding. Each pulse may represent the passage of a unit of time. or a unit of quantity, such as a given flow of liquid. The termination of one operation may automatically initiate the next operation, the programme of operations being in the form of a punched sheet which cooperates with a photo-electric system or a system of contact fingers and drums, one set of punchings determining the sequence of the operations to be performed and another set determining the number of steps the rotary switch must make to terminate each operation, the arrangement being such that the sheet advances to a new position to present another set of punchings at the termination of each operation. In a modified arrangement, which is less flexible as regards change of programme, the programme sheet is dispensed with and the programme determined by which contacts of a rotary programme switch (of the pre-selector telephone type) are connected to the controlled apparatus. Permanent connection between the contacts of another bank of this switch and the contacts of the rotary pulse counting switch determine the duration of each operation. Manually operated multi-way switches may be provided in these " permanent " connections and between the controlled apparatus and the contacts of the programme switch to allow a certain flexibility of programme. When the apparatus is required to control a single operation only, such as the delivery of a predetermined quantity of fluid, the pulse counting mechanism may comprise three rotary stepping switches arranged to count hundreds, tens and units, respectively, and manually operated selector switches connected so as to determine the count by each stepping switch.

Title: Improvements relating to kilns for drying grain or like substances
IPC: F26B17/14
Filed: 1934-11-15
Abstract: 435,077. Drying grain &c. HAMILTON, G. S., 42, Poolbeg Street, Dublin. Nov. 15, 1934, No. 32840. [Class 34 (ii)] In a kiln, Fig. 1, for drying granular and like substances such as oats, each wall of the kiln is formed of an inner and outer series of equi-spaced louvres, 1<d>, 1<c>, to form a zig-zag passage for the grain. A furnace 4 is arranged outside the kiln and heated air is forced by a fan 5 through a pipe 6 to effect the drying. The louvres 1<d>, 1<c>, Fig. 5, are pivoted in slotted tubular members 8 and rest on rods 7 so that, if necessary, the flow of grain can be stopped by removing any one. of the louvres 1<c> and resting it against an opposite member as shown dotted, Fig. 5. This closes the zigzag passage. In a modification, Fig. 6, each louvre is supported on an inclined ledge 9 cast on the sides of the wall uprights 1<a>. The ledges are continued at their inner edges to form upper ledges 9<a>. When a louvre is removed from its supporting ledge 9 and transferred to its corresponding ledge 9<a>, it can be pushed inwardly to meet the opposite louvre and so close the passage. The discharge of the dried grain into a hopper 3 is controlled by valve mechanism Fig. 8. Below each section of each wall is a slide block 10 to control openings 11 between plates 12, 13. Each block 10 is connected to a bar 10<a> the other end of which is connected to the corresponding slide block at the opposite side of the kiln. Any suitable mechanism may be used to effect movement of the bars 10<a> and valves. In a further modification, the furnace may be arranged partly below the kiln instead of outside it as in Fig. 1, with a fan inside the kiln.

Title: Apparatus for code communication
IPC: H03M7/48
Filed: 1966-07-21
Abstract: 1,140,069. Facsimile systems; Data transmission systems. ELECTRONIC IMAGE SYSTEMS CORP. 21 July, 1966 [22 July, 1965], No. 32855/66. Headings H4F and H4P. In a data transmission system data is transmitted in any one of a number of codes, the code in use at any time being that which produces the smallest output of data for a given input. The input data is monitored continuously and the coding changed accordingly. In one embodiment the input data is stored in a buffer and passes to a plurality of coders. A number of counters count the number of symbols produced by the associated coders and the counts pass to a logic arrangement which is also fed by the output of a counter counting the input data symbols. The logic programme is detailed in the Specification. It determines which coder is giving the smallest output and whether or not that output is smaller than the input count. If that output is smaller the data is coded by that coder but if it is larger it is sent unaltered. The logic also determines how much of the data in the buffer is to be sent in the chosen code, and precedes the coding by sending first a unique word which always precedes a coding change and then a word indicating in what code the data following will be transmitted. At the receiver, the unique word and coding word cause the appropriate decoder to be selected for decoding the data. As applied to a facsimile system, a c.r.t. scans the copy and a photo-multiplier arrangement detects the black-white and white-black transitions. These are counted during each line scan and a threshold unit pulses as each of a succession of thresholds is exceeded. These pulses are counted. At the end of the line scan the latter count is used to adjust the word length of a run length counter. There is then transmitted a unique data word which always precedes a word indicating the selected word length and which indicates to the receiver that a line scan is about to begin. This is followed by a second scan of the line and the resultant transmission of words indicating the distance of the transition from the position of the transition indicated by the previous word and indicating the type of transition. It may be arranged that the second scan shall stop at the last transition in a line as determined during the first scan. The receiver synchronizes on the unique words and adjusts the local decoder according to the coding words, prior to decoding for reproduction of the copy.

Title: Analyser utilising the scintillation spectrometry of back-diffusing beta particles
IPC: G01T1/36
Filed: 1962-08-27
Abstract: 1,014,875. Photoelectric analysis using back-scattered #-particles. R. W. PRINGLE and D. H. PRINGLE. Aug. 27, 1963 [Aug. 27, 1962], No. 32896/62. Heading G1A. Characteristics, such as thickness, or the proportional composition of a sample 3 (Fig. 3, not shown) are determined by the use of apparatus, which is used to investigate beta particles backscattered from the sample, comprising a detector which is either a scintillating phosphor 4 and photomultiplier 6, or a semi-conductor detector, an amplifier 7, a pulse height analyser 8 to select only pulses of a predetermined energy level for presentation to an indicator 9, which registers the pulse count. The shielded radiation source 1, directing beta particles on to the sample is of e.g. T1, Sr or Pm and the scintillator, optically coupled to the photomultiplier, of plastics. Using the principle that for a certain pulse height range, the intensity of the back-scattered particles is proportional to the atomic number of the sample investigated, the apparatus has application in the investigation of bicomponent samples in solution and of mixtures of two samples. Analysis of sulphur-oil mixtures is possible and of water-oil mixtures, for measuring the water-oil rates at a well head, when the use of a glass scintillator is necessary. The effect of thin layers of coal dust on the surface of rocks and of coal dust-limestone dust mixtures, may be investigated, for coal of different ash contents. The ash content itself may be measured. The apparatus may be used as a thickness gauge for measuring the thickness of e.g. a thin layer of tin or other metal on steel plate, or of a P.V.C. coating on wallpaper. Alternative types of scintillator for use in certain applications are anthracene, stilbene, glass (for high temperature work) and sodium iodide crystals.

Title: Improvements relating to selecting switches such as used in automatic telephone systems
IPC: H01H63/20
Filed: 1929-10-30
Abstract: 339,434. Siemens Bros. & Co., Ltd., Riber, C. R., and Jones, T. H. Oct. 30, 1929. Automatic exchange selectors.-Ratchet operated selectors are driven by a pair of magnets operated alternately and acting on opposite ends of a single armature or on separate armatures each of which restores the other. In the former case the armature acts on the ratchet through two pawls 31, 32, Fig. 6, carried by a pivoted member 33. Each magnet is provided with a winding in series with and arranged to counteract the flux due to the main winding of the other. Preferably the direction of the flux is always the same in the common part of the magnetic circuits. The magnets are connected up in turn by a bowed contact spring 28 arranged to snap over against one or other of two contact screws under control of a forked tail 27 on the armature. Fig. 1 shows a two motion flat switch using a bare wire multiple as the terminal field. The wiper carriage is moved to select a row by the magnet pair 1DM the ratchet wheel of which is geared to the screw 7 and to select a set of terminals by the pair 2DM which similarly drives the square shaft 16 of a pinion 18 which drives a rack 4 carrying the wipers. Connection is made to the wipers by flexible leads or by means of bus-bars and sliding contacts. The switch is restored with the aid of a magnet pair RM which reverses the direction in which the wiper carriage is driven in response to further impulsing of the driving magnets. The latter are disconnected by springs 57, 60 in the normal positions of the wiper carriage. The reversing magnets act through pivoted members 47, 47a and a roller 50 in such a way that the gearing is definitely locked in one or other position until the magnet is operated again. Spark quenching condensers 55 may be mounted as shown.

Filed: 1962-08-28
Abstract: 964,596. Radio navigation. NORTH AMERICAN AVIATION Inc. Aug. 28, 1962, No. 33045/62. Heading H4D. In an air (or space) craft position finding system utilizing no more than a pair of targets spaced along the runway, Fig. 1 (not shown), one of the targets is tracked by the aircraft radar and data is derived from the measurement of slant range to at least one target and the angular displacements in two orthogonal planes of one target relative to the other, to represent the craft's position in terms of deviation from a programmed position; one such displacement is #el, Fig. 3, and the other is the azimuthal counterpart #az. The displacements are measured by a monopulse tracking radar as described in Specification 900,047, and elevation and azimuth error signals relative to a programmed glide and landing path are displayed or control an automatic pilot. The path is programmed as a function f of range r2. The targets may be active or passive, in the former case they reply on a carrier frequency different from that of the craft's radar. As an alternative to a programmed landing the invention may be used with the system described in Specification 964,595. Aerial 30, Fig. 5, is locked in azimuth and elevation to target 18, and a range video-frequency signal corresponding thereto is fed to a rangetracking unit 38 which affords a D.C. signal corresponding to range r2 and a range gate signal corresponding to target 17. A range gate signal corresponding to target 18 is provided by delay line 40. The two range gate signals are fed to elevation and azimuth error channels 34, 35 to synchronize associated known "box-car" " detectors and gain control circuits. Unit 25 generates an output signal f(r2) and the elevation error signal eel = f(r2) - #el is fed to a " landing coupler " 22 which controls an automatic pilot; or a pilot's indicator may be controlled, Figs. 8, 9 (neither shown). The Specification includes further description relating to Fig. 5: (1) the monopulse " sum" channel includes an instantaneous automatic gain control (A.G.C.) circuit, Fig. 6 (not shown); (2) a range tracking unit, Fig. 7, in which the " sum " channel video-frequency output signal Es is compared with the range-r2 gate derived therein to give a corresponding D.C. error signal which is integrated and summed with a voltage from a potentiometer 100 controlled manually, when initiating automatic tracking, to produce overlap between the ranger2 gate and the target echo as viewed on a radar display: the D.C. output from circuits 78 controls time modulator 110; (3) the elevation channel of the landing coupler, Fig. 8 (not shown), is fed with signal #el, to which swept gain is applied, and stability augmentation signals (indicated as " compensation signals " in Fig. 6); and (4) the azimuth channel of the landing coupler, Fig. 9 (not shown). U.S.A. Specifications 2,836,810 and 3,078,457 also are referred to.
