Abstract: 1,019,487. Spiral shoots; piling material. ANGLO - TRANSVAAL CONSOLIDATED INVESTMENT CO. Ltd. Oct. 21, 1964 [Oct. 23, 1963], No. 42944/64. Headings B8E and B8S. An anti-breakage trunking assembly comprises a hollow tower 5, Fig. 1, with a top inlet opening and a bottom discharge outlet, the tower enclosing and supporting a vertical spiral shoot 10 and having segmented walls, the segments 7, Fig. 3, of which are spaced apart to form vertically extending feed openings 8 between the segments. The tower 5 is erected around the bottom outlet 2 of an open coal stockpile bin formed by making an inverted conical excavation in the earth, a feeder 3 being disposed beneath the outlet 2 and discharging on to a conveyer 4. The spiral shoot 10 is supported by buttress walls 9 extending from the segments 7, separate compartments 11 being thus formed which communicate with the respective openings 8. The tower is built of concrete or sheet metal and supports the top end of a supply conveyer 13. In use the coal from the conveyer 13 spills out of the openings 8 to build up the stockpile. When the feeder 3 is operated the coal flows inwardly from the top of the stockpile through the openings 8, the lower layers of coal bridging across the openings. Benches 16 are formed on the outside of the segments 7 to enable the lowest levels of coal situated outside the segments to flow into the tower. The buttress walls 9 may be dispensed with or replaced by external buttress walls. The tower walls may be formed by segments of a circle.

Title: Improvements in or relating to plastics pipes
IPC: B29C48/12
Filed: 1969-08-29
Abstract: 1278332 Welding; moulding pipes KAMPHUIS KUNSTOFFEX NV 29 Aug 1969 [4 Sept 1968] 43119/69 Headings B5A and B5K [Also in Division F2] A method and apparatus are described for making a pipe, e.g. a sewer pipe, from a plastics strip having a cross-section with one or more projections which form helical ribs when the strip is helically wound and welded or cemented along the helical seam to form the pipe, the seam running between adjacent ribs. In a preferred embodiment the strip (Fig. 2) is produced by extrusion, and the projection is a hollow trapezoid, with the shorter parallel side 2 on the outside of the pipe, to prevent the projection ribs from bending over during the making of the pipe, or when subsequently under load, and the sum of the thicknesses of parallel wall 1 and 2 being substantially equal to the thickness of web 5. Sides 6 of the strip may be bevelled to form a channel to facilitate welding or the edging portions of web 5 may be formed into complementary ribbed and grooved sections (Fig. 4, not shown), those on adjacent turns engaging one another as the pipe is wound, the overlapping portions each being half the thickness of the remainder of web 5. After extrusion the strip may be passed into a cooled vacuum shaper of helical internal profile, and thus directed into a helical path, and formed into a pipe, the turns being welded together as the pipe leaves the shaper. Alternatively the strip may be wound on a mandrel and the turns joined together before the pipe thus formed is fed through a vacuum shaper in which the projections and seams are given finishing treatment. The seaming may be carried out by hot air directed by nozzles, by high-frequency or ultrasonic welding, or a weld filler strip may be inserted into the then V-shaped groove formed by the chamfered edges. Alternatively the edges are butt-welded. A synchronized saw may be provided to cut the pipe into lengths.

Title: Electromechanical transducer
Inventor: JEWELL ANTHONY JOHN
IPC: H04R23/00
Filed: 1964-10-23
Abstract: 1,030,490. Frequency and amplitude modulation systems; microphones. STANDARD TELEPHONES & CABLES Ltd. Oct. 23, 1964, No. 43312/64. Headings H3R and H4J. Acoustic or other pressure mechanically applied to a semi-conductor junction of a transistor or tunnel diode forming part of an oscillator, frequency modulates it or mainly amplitude modulates it if applied at a transistor - emitter - base junction. A limited area of a P.N. junction, where it emerges at the surface of a semiconductor, may be pressed upon by the tip of a probe. The probe 4 may be mounted on a pivoted arm 6 with a screw 9 applying initial static pressure to the probe and P.N. junction, and with an acoustic diaphragm 5 connected to the probe to vary the pressure on a transistor collector/base or emitter/base junction, or the forwardly-biased junction of a tunnel diode. With a resonant circuit connected to the transistor or diode the oscillator of a low-power transmitter may be formed. Emitter/base pressure varies the transistor gain and amplitude modulates the oscillator. But collector/ base or diode junction pressure mainly varies internal capacity and frequency modulates it. The limited area subject to pressure may be insulated by an oxide coating.

Title: Atomic fluorescence spectroscopy system
Inventor: KELLY MICHAEL A
IPC: G01N21/64
Filed: 1970-09-10
Abstract: 1282659 Fluorescence spectroscopy HEWLETT-PACKARD CO 10 Sept 1970 [12 Sept 1969] 43363/70 Heading G1A In an atomic fluorescence system in which a source 21-25 provides radiation having spectral lines characteristic of the atomic species being detected in a sample contained in a chamber 11, the sample is periodically electrically energized to provide a vapour and a photo-detector 43 is gated by the energizing pulse source 59 to provide an output only between pulses. In these betweenpulse periods the output from the detector 43, which may be a photo-multiplier consists of the spectral information regarding the species, superimposed upon unwanted thermal radiation. These two components are separated by chopping, 63, or pulsing the light source at a lower frequency -50Hzthan the sample energizing frequency -500Hz, and employing a switch 49 in synchronism with the light source modulation. Signal averager 51 thereby recieves the component of the detector output corresponding to fluorescence plus thermal radiation, while averager 53 receives the component corresponding to thermal radiation only, i.e. that produced when light from the source is not incident on the sample. These two signals are subtracted and supplied to a log circuit 57 whose output is proportional to the concentration of the species in the sample. The log circuit output may be fed back to a switch 19 of the pulse supply to control the supply of energy to the sample chamber and hence prevent over excitation of the sample. The lamps 21-25 are metallic vapour electrodeless discharge tubes. Each one is characteristic of a particular element and they are employed in sequence for multi-element analysis. Mirrors 39, 41 are provided at each end of the light path to maximize the incident radiation. A lens system may be provided between the sample chamber and the detector, and a monochromator or filter may also be provided in this position for selective attenuation of the emitted light. The gating pulses from the generator 59 are delayed by a one-shot multi-vibrator 61.

The sighting screen is provided with cross ribs 12 and the tube 8 may be notched at 10 to centre these. In use the X-ray tube and the screen are so adjusted that the central beam of the tube produces a shadow of the foreign body on the centre of the sighting screen. The sighting screen is then removed, a pencil is inserted in the tube 8 and a mark is made on the body under examination. This position is then marked by a metal pointer 15, Fig. 9, which may be secured by plaster. Then a photographic plate is placed under the body and a stereoscopic pair of pictures is made by which the depth of the foreign body may be calculated. The screen 6 may then again be centred over the foreign body and the probe inserted through the tube 8 the calculated distance into the body. The Specification as open to inspection under Sect. 91, describes also a pair of dividers Fig. 17 (Cancelled) having a scale 26 thereon so calibrated that when the points 20, 21 are placed on the two images of the foreign body on the stereoscopic photograph the scale 26 will give the depth of the body beneath the surface. A scale also is described by which the depth may be determined by the use of ordinary spring bow dividers. A probe for use with the apparatus comprises a socket 36, Fig. 10 (Cancelled), for insertion in the tube 8 and guiding a needle 37 and pencil 38. The socket 36 has a flange resting on the top of the tube 8 and the punch is graduated and provided with an adjustable collar 40 which is set to drive the point the calculated distance into the body under examination. To prevent deflection of the needle it may have a coned tip engaging a coned recess in the punch. This subject-matter does not appear in the Specification as accepted.

Title: Digitally onctrolled winding apparatus and method
IPC: H02K15/04
Filed: 1974-10-10
Abstract: 1461290 Coil-winding apparatus ESSEX INTERNATIONAL Inc 10 Oct 1974 43945/74 Heading B3A [Also in Division G3] Apparatus for winding dynamo - electric machine field coils on a stepped form using a rotating flyer mounted on a linearly translatable support includes electrical signal generators producing outputs indicative of linear and rotary motion which are compared to form a difference signal which is used to control the drive of the flyer and produce a winding of a desired pitch. A third signal is generated when the first coil is completed, and is compared with one of the other signals in order to control the pitch of the connection between the first and second coils. As shown, successive coils are wound by a flyer 22 on steps 136-144 of a turret form 136A. The coils may be wound starting with the smallest or the largest, or partly in each direction, according to a selected mode of operation. The flyer shaft 24 is rotated by a splined shaft 64 drivable by a high speed motor 90 or by a low speed motor 82 which is engaged when only a small number of turns remain to be wound. The shaft 24 is moved axially by an hydraulic cylinder 48, controlled by a valve 58, responsive to signals from control logic circuitry. Pulses representing increments of axial motion are generated by a device 110 and fed to a counter. Another counter receives pulses from a wheel 104 rotating with the shaft, and the counts are compared after division by a selected ratio to produce an error signal which controls the hydraulic drive of the shaft 24 to produce a desired winding pitch. The total number of turns and the number of layers in each coil are preset, and sequencing signals are produced after each stage. When the flyer is to be advanced to wind a coil on a different step of the form, a signal is produced causing the pulse dividing circuitry to set a new datum for the ratio of rotary to linear speed and thus control the pitch of the connection between the coils to a desired value. The wheel 104 also serves as a motion detector operating in conjunction with a brake 100, and another wheel 102 counts the number of turns in each coil. Details of the logic and counting circuits, comprising BCD counters and converters, AND gate logic and coincidence circuits are given, Figs. 5-10 (not shown). Further constructional details are also given, Figs. 1-3 (not shown), and the operator control panel is described, Fig. 4 (not shown).

Filed: 1959-12-28
Abstract: 912,326. Coffee and like extracts. KOELLE, G., and KOELLE, S. Dec. 28, 1959, No. 43964/59. Class 129. Coffee or other material is extracted by circulating the extracting liquid under reduced pressure in a closed circuit, withdrawing a small amount of the liquid from the circuit and using it for cold extraction of the material under reduced pressure and feeding the product back into the circuit; a second extraction with the same or a different liquid, and preferably at a more reduced pressure, can be carried out. The vacuum conduit 12 draws cold water from a container 2 through a steam-heated section to a collector 6 whence the liquid can return to the container. Vapour is withdrawn from the collector through a pipe 9 and past a cooling coil 10 where it condenses and falls on the material to be extracted in the vessel 13, where it collects until it siphons over the tube 16 back to the container 2. The material can be further extracted with the same or a different liquid and under more reduced pressure. The extract is fed to a container 20 containing a stirring mechanism, and other materials such as fructose can be added. From the container 20, the extract passes to a drier 23 and storage receptacle 24. The extracted material in the vessel 13 is dried in a drier 25 and ground in a mill 27, after which it can be added to the extract in the container 20. A simpler form of apparatus is also described.
