Abstract: 1,166,973. Dispersible flour agglomerates. BAY STATE MILLING CO. 25 April, 1968 [5 May, 1967], No. 19631/68. Heading A2E. Dispersible flour agglomerates are prepared by modifying a small portion of a flour to at least partially gelatinise the starch therein, for example by cooking, and forming this flour into a thin slurry, which is dispersed in the form of fine droplets together with a relatively large quantity of a flour, whereby the droplets and flour particles commingle, and the thus wetted particles come into contact and adhere to each other to form the agglomerates, which are then conditioned, for example by drying to the desired moisture content.
Patent GB-698091-A (GB)
Title: Improvements in or relating to means for the transport and delivery of finely divided materials
IPC: B60P3/22
Filed: 1950-08-08
Abstract: 698,091. Vehicles and storage chambers equipped with conveyers; hoppers. WILSON, J. N. July 30, 1951. [Aug. 8, 1950] No. 19709/50. Classes 78 (i) and 78 (iv). A false bottom comprising plates 10 hinged at their upper ends and adapted to meet at their lower ends prevents finely divided material carried in a container from clogging conveying means (as illustrated, a screw conveyer 7) provided in the container for unloading it. In the semi-trailer vehicle illustrated the plates 10, which are formed at their lower ends with rubber seals 19, are raised and lowered by hydraulic jacks 11 which may be locked in their extended positions. When raised the plates may be vibrated by suitable electrical or mechanical vibrator units or, as shown, by cams 12 acting on the jacks 11 through levers 13 carried by brackets on the walls 9 of the body, or by both. Vibrators may also be provided on the walls 9. Several pairs of plates 10 may be arranged end to end and their controls may be interlocked to ensure that the pairs can be lowered only in proper sequence and after the conveyer 7 has been started. The conveyer 7 delivers to a hose coupling near the rear of the vehicle and preferably slopes downwardly. Its drive cannot be started until the outlet is opened and includes means to prevent reverse rotation. The body is filled through a hose coupling at the rear of the body and above an upwardly inclined screw conveyer 6 which cannot be driven unless the plates 10 are closed. A further hose coupling (not shown) in the upper part of the body enables it to be kept under exhaust. The conveyers and the shafts 13 of the vibrator cams may be driven from a motor on the trailer, from the tractor engine or from any other source of power and the drive may be protected by a frangible pin. The drive to the camshafts 13 may be arranged to be effective only when the plates 10 are raised. Specification 592,521 is referred to.

Title: Road signalling apparatus
IPC: G08G1/08
Filed: 1927-02-08
Abstract: 274,288. Kirby, T. C. Feb. 8, 1927. Road signals.-In apparatus for signalling the approach of vehicles at road crossings &c. by means of electric circuit closing devices sunk in the roadway, lamps arranged to shine along the roadways are controlled by switches operated by two opposed windings energized in turn to initiate and cancel the signals. Plates 3 in the North and South roads are arranged to close the circuit of an electromagnet 20 by means of which contacts 22, 23 in the East and West signal lamp circuit are closed, while plates 4 close the circuit of a second electromagnet 31 to open the contacts on the vehicle reaching the crossing. In an alternative arrangement, the nullifying plate 4 for each approach road is placed on the oppositeside of the crossing, while the plate 3 is placed near the crossing. In this case, a third plate may be placed some distance from the crossing to cause the signal lamps to give a preliminary warning flicker. Similar electromagnets 25, 34 operate a switch to open and close contacts 27, 28 when plates are operated in the East and Westroads. The actuating plates 3, 4 are contained in a slot in a housing 1 and carry by means of ball joints 12 conductors 10, which, when depressed, engage stationary conductors 11. A part 17 of the housing is removable for inspection. Each housing may comprise several sections, one of which may be depressed by light vehicles, being suitably marked to indicate this. The four signal lamps may be carried by a standard in the centre of the crossing, and two lamps may be used to face each road to indicate along which side road the traffic is approaching. According to the Provisional Specification, cutout mechanism may be employed to prevent a vehicle proceeding away from the junction from giving a signal if it passes over the plates.

Filed: 1930-06-30
Abstract: 351,741. Rotary pumps. WADE, J. T., Fairfield Works, West Wycombe Road, High Wycombe, Buckinghamshire. June 30, 1930, No. 19830. [Class 110 (ii).] Movable-abutment type.-An eccentric piston has an outer ring 11 which rolls around the inner wall of a casing 3, being supported on a roller or ball race 10, and co-operates with pivoted abutments 17, the free ends of which are pressed against the ring 11. The outer ends 18 of the abutment 17 control the inlet ports 19. The abutments have trunnions 16 supported in bearings 15 and extensions of the trunnions are fixed to torsion springs 21 which are held in caps 22. A packing strip 13 is pressed against the abutment 17 at its pivoting axis, which is also the axis of the trunnion. Packing rings 23 are spring-pressed against the end of the casing. Fluid to be pumped enters a port 26 and the pumping chamber by way of ports 19, which are connected by a conduit 28, 29. The outlet ports 30 are controlled by spring-loaded valves 31 and lead to a delivery port 34 through channels 32, 33. The machine may be modified to act as an engine. In some cases the abutments mav be controlled by external cams and levers. More than two abutments may be provided. The casing is water-cooled.
Patent GB-1120545-A (GB)
Title: Method of transmitting and receiving a short wave communications signal
IPC: H04B1/68
Filed: 1966-05-05
Abstract: 1,120,545. Single sideband modulation. C.I.T.-COMPAGNIE INDUSTRIELLE DES TELECOMMUNICATIONS. 5 May, 1966 [5 May, 1965; 1 Oct., 1965], No. 19896/66. Heading H3R. In a single sideband communication system a narrow band signal is transmitted in addition to the sideband and used in conjunction with the sideband at the receiver to reconstitute the carrier. At the transmitter, Fig. 1, signals from a microphone 1 and from a carrier source 3 feed a modulator 2 the output of which passes to a wideband filter 5 which selects one sideband and to a narrow band filter 4 which selects a small part of the other sideband. The outputs of the filters are added and transposed in frequency by means of mixers 7 and 12 with associated oscillators 8 and 13, amplifiers 6, 11 and 15, and filters 9 and 14. At the receiver Fig. 3 (not shown), the input is transposed back to the original signal carrier frequency (in mixers 23, 28), and the narrow band signal and the sideband signal are separated by respective filters (30, 31). A further filter (37) selects a part of the sideband corresponding to the narrow band signal, and this part is fed with the narrow band signal to a mixer (33) which produces an output at twice the nominal carrier fiequency. This output is limited (35) and fed to a frequency divider (36) which halves the frequency and supplies the output demodulator (39). A change of frequency due to Doppler shift or to frequency drift affects equally both inputs to the demodulator (39) so that the output is unaffected. In the arrangement shown in Figs. 1-3, the narrow band pilot signal is on the opposite side of the carrier from the information sideband signal, and this requires one of the oscillators in both the transmitter and the receiver to operate at a frequency which is not a round number. In a modification, Figs. 4-6 (not shown), the narrow band signal is transposed to a frequency range beyond the sideband signal by means of an extra modulator (57, Fig. 4, not shown), at the transmitter, and transposed back again at the receiver (modulator 80, Fig. 6, not shown). This system allows the use of oscillators at frequencies which are round numbers. A stable local oscillator (94, Fig. 6, not shown), may be provided in the receiver as an alternative source of carrier signal to that described above.

Patent GB-715202-A (GB)
Title: Improvements in stabilisers for polyvinyl chloride and interpolymers containing vinyl chloride
IPC: C08K5/21
Filed: 1951-08-24
Abstract: Vinyl chloride polymers are heat-stabilized by incorporating in the polymer, which may be plasticized, an epoxyurea of the formula: <FORM:0715202/IV (a)/1> in which Ar represents a substituted or unsubstituted aromatic radical.  The polymer may be polyvinyl chloride or a copolymer of vinyl chloride and vinyl acetate. Specified stabilizers are ureido-phenyl-glycide ether and ureido-naphthyl-glycide ether. Plasticizers mentioned are dioctyl phthalate, dialkyl adipates and tricresyl phosphate.ALSO:Epoxyureas of the formula <FORM:0715202/IV (b)/1> where Ar represents an aromatic radical which may be substituted are made by reacting hydroxy-arylamines with a cyanate to form the desired hydroxyphenylurea and converting the latter with epichlorhydrin into the epoxyurea.  In example (1) ureido-phenyl glycide ether is made by reacting epichlorhydrin and metahydroxyphenylurea made from meta-aminophenol hydrochloride and potassium cyanate; in example (2) para-aminophenol replaces meta-aminophenol whilst in example (3) a ureidonaphthyl glycide ether is obtained from 6-amino-1-naphthol in a manner similar to example (1) by way of hydroxynaphthylurea.  The epoxyureas are used as stabilizers for vinyl chloride polymers.

Title: A new or improved mechanism for variably controlling needles of a knitting machine
IPC: D04B9/00
Filed: 1933-07-14
Abstract: 410,640. Knitting - machines. HEMPHILL CO., Central Falls, Rhode Island, U.S.A. -(Assignees of Lawson, R. H. ; 55, Cooke Street, Pawtucket, and Gagne, A. ; 107, Hendricks Street, Central Falls, both in Rhode Island, U.S.A.) July 14, 1933, No. 20004. Convention date, July 18, 1932. [Class 74 (ii).] In a machine of the independent-needle type the needles 6 interengage with jacks 9 but are capable of movement independently thereof for stitch and pattern forming purposes. The jacks are constantly actuated during a plurality of courses and are further controlled so that the ones selected shall cause their companion needles 6 to function differently from the rest. Companion needles and jacks have interengageable formations 122, 123 which cause the needles to move with the jacks to non-knitting positions. Each jack has a lower butt 135 and a number of frangible selecting butts 131 and can be freed from its needle by an outward movement. This is imparted by a cam 120, the jacks rocking about points adjacent their lower ends. The jacks are restored to needleengaging position by selective action of plungers 15 on the butts 131. The action is assisted by a radially movable cam 132 acting on the needle butts 133. This cam is operatively connected to the instep cam and is held away from the butts 133 during reciprocating knitting. The jack-retaining spring bands 170 are held out of the path of movement of the plungers 15 by plates 172. The plungers 15 are selected by a drum consisting of a number of pattern discs 11 with frangible butts, removed according to the pattern to be formed. The drum is racked during the knitting of special stitch fabric and then comes to rest until brought within range of a starting pawl. The stud 12 on which the drum pattern disc assembly turns is mounted on a pivoted base the position of the drum relative to the plungers 15 being regulated by the main pattern drum. In a modified form of pattern disc assembly the plungers 15 are permitted to yield on impact with an oversize jack and thus avoid damage to the machine. The butts 135 are lowered by a cam controlled from the main pattern drum. This cam has two positions so that it can, during knitting of the stocking foot &c. miss the shorter butts extending part way round the jack circle and corresponding to the non-patterned sole. Specification 20101/09, [Class 74 (ii)], is referred to.

Abstract: 666,796. Phase-difference measurements. ELLIOTT BROS. (LONDON), Ltd., HAWKES, H. D., and THOMPSON, L. G. Sept. 8, 1950 [Aug. 5, 1949], No. 20471/49. Class 37. In a moving-iron phase displacement meter a single rotatable element of magnetic material is magnetized by an energizing coil whose magnetic circuit is substantially a closed path of magnetic material. The stator comprises a shallow cup-shaped housing 13. Fig. 2, of magnetic material provided with a number of coils 14 wound on inwardly projecting poles 15. The housing 13 has a central upstanding boss 16 forming an iron core for the exciting coil 17. The boss is bored with a clearance hole for the spindle 18 which is mounted on a foot bearing. Secured to the spindle 18 is a sector 19 of magnetic material having a radius such that its arcuate edge moves between the poles 15 with minimum clearance. The clearance between the sector 19 and the upper edge of'the boss 16 also represents an air gap in the magnetic circuit of the coil 17 and is made a minimum. The spindle carries a pointer 20 or a pen arm or a mirror. A flux distribution ring 21 is secured to the poles 15 to form an annular path for the flux of the rotating field. Assembly of the meter is simplified as the field winding 14 on the stator and the exciting coil 17 can be assembled in the housing independently of the moving system. In a modification, Fig. 5, the stator assembly consists of an annulus 22 and a disc 23, both of magnetic material spaced apart by magnetic cores 24 on which are wound the field windings 25. At the centre of the disc 23 is an upstanding hollow boss 26 forming the core of the energizing coil 27. The bore through the boss 26 forms a. clearance hole for the spindle 28 carrying the magnetic sector 29. For indicating the power factor of an unbalanced threephase load three stator units are coaxially mounted and the moving iron systems have a common spindle, on which the magnetic sectors are mounted displaced with respect to each other by 120 degrees. The phase displacement meter may be used as a synchroscope by exciting the field windings from one supply and the energizing coil from the other.
