Title: Tanks for sewage-treatment plants
IPC: B01D21/34
Filed: 1956-10-04
Abstract: 845,198. Gravity-separation apparatus. SCHREIBER, A. Oct. 4, 1956, No. 30329/56. Class 46. [Also in Groups X, XXI and XXIX] A substantially cylindrical tank, Fig. 2, consisting of staggered courses of curved bricks 1, 2, Fig. 3, the concave surfaces of which face inwards and some of which (2) are provided with vertical ribs 5 offset from their centres and projecting radially inwardly, is characterized in that successive courses of ribbed bricks are arranged one upon the other with their ribs aligned vertically to form uprights for the tank, while the non-ribbed bricks fill the spaces between the uprights. Preferably the radius of curvature of the bricks differs from that of the tank so that wedge-shaped spaces are left between adjacent bricks for the introduction of jointing material. Preferably also the length of a brick bears an integral ratio to the circumference of the tank so that only whole bricks are used in the construction and one size of brick serves for many tanks. Thus if the length is 100#/8 units, eight bricks are required for a tank of 100 units diameter, twelve for a tank of 150 units diameter and so on. Cornice bricks 8 may be provided, and may be combined to form an integral reinforcing ring of triangular section, Fig. 3, left, or a single course of cornice bricks with larger surface uppermost may be used to form the coping at the top of a tank, or a ledge for partitions or fittings (Fig. 3, right) or, (inverted) at the bottom to form a supporting base. In Fig. 10 (not shown), the tank is divided into four communicating quadrants by vertical partitions meeting at right angles at the tank centre, the liquid being introduced into the first quadrant, and supernatant being discharged from the fourth by a tilting device which operates regularly and automatically (see Group XXI). Such a device having an inlet siphon 71, Fig. 15, serves to discharge nearly all the contents of a tank. In Fig. 16 grease is detained in a tank 80 whilst the remainder of the liquid is discharged via an apertured pipe 88 having an adjustable slide 90, and a chamber 85 with outlet pipe 81<SP>1</SP>, (see also Group XXI). In Fig. 19 waste water or sewage enters at 101, supernatant is discharged at 102, and sludge via a pipe 107 and a device 108, 109 similar to that in Fig. 16.

Title: Improvements in or relating to shovels, scoops and the like
IPC: A01K1/01
Filed: 1935-11-02
Abstract: 448,823. Dustpans; handles. PRIOR, D. M., 7, Quernmore Road, Bromley, Kent. Nov. 2, 1935, No. 30356. [Class 19] [See also Group I] A shovel, scoop, or the like is provided with means for trapping material to be collected in front of its leading edge, this means being so interconnected with it as to permit relative sliding movement in a substantially horizontal direction to transfer the trapped material to the shovel or the like. The trapping means may take the form of a pusher member comprising a metal or other rigid plate or ram, or a brush or strip of rubber or other flexible material. A shovel which may be used without undue stooping comprises a walled tray 1 provided with a handle 3 and a hollow handle shaft 2 of the shape shown. The walls may be shorter than the base of the tray. A pusher plate 6 is carried by spring-pressed slide rods 5 sliding in guide tubes 4. The rods are connected by a cross-bar 9<a> connected through power-transmission linkage to a lever 10<a> pivoted on the handle 3 and movable by the hand holding the shovel. The power is transmitted through a thrust rod 12, a pivoted bell-crank lever 13, 15, and a link 16. Instead of the plate 6 being moved towards the shovel to transfer the trapped material, the shovel may be tilted so as to take its bearing on the ground by means of the lower edge of the plate 6 and may then be pushed bodily towards the plate. The power-transmission mechanism may be dispensed with. In a modification, the handle shaft may be parallel to the leading edge of the shovel and the pusher may be actuated by Bowden or other mechanism. The pusher may be arranged to fold or to be movable out of the way.

Title: Improvements in and relating to alternating-current electric generators
IPC: H02K17/42
Filed: 1922-07-25
Abstract: 210,097. Contell, F. July 25, 1922. Exciting; high-frequency machines; rotary transformers.-In an alternating-current generator excited by alternating-current in which the irequency is increased or decreased by half of the product of the pole number and the speed per second in accordance with the direction of rotation of the exciting field, for the higher frequency the generating coils are grouped in mesh and for the lower frequency they are grouped in star and the exciting current is increased in order to give approximately equal terminal volts in both cases. The exciting current may be derived from the machine itself, from mains, or from another machine on the same shaft as the main generator. Fig. 2 shows a group which gives a fixed frequency independently of the speed of the set and consists of an auxiliary alternator N excited with alternating-current and exciting a main alternator M on a common driven shaft P. If f be the frequency supplied to the machine N, for example through leads 1, 2, 3, this machine excites the machine M with a frequency of f - n p / 2 where n and p are the speed and pole number of the-machine N. The machine M has the same pole number p and is so arranged as to give a frequency of f n p / 2 + n p / 2 i.e. it gives on the bus bars 4, 5, 6 the original frequency f independently of the speed of the set. By means of two such sets of two generators and a series of alternator connected so that the current generated by each one excites the next one to give a cumulative frequency increase in the series in known manner, currents of still higher frequency may be generated as follows :-The current from the last machine of a series of sav ten generators is used to energize one set of two generators, as shown in Fig. 2, and the constant high-frequency current from this set is used to excite the first of the series of ten machines again. This gives a further increase of frequency which is taken up on the second set of two generators which remains running as a selfexciting constant high frequency machine, the series of generators being no longer required. The cores of the high frequency machine are made of non-magnetic materials to reduce hysteresis losses. Specification 23396/08 is referred to.

Title: Improvements relating to radio navigation
Inventor: ARCHIBALD BEAVAN HARRIES
IPC: G01S1/02
Filed: 1960-09-05
Abstract: 937,420. Direction finders. M. G. G. ARCHIBALD. Sept. 22, 1961 [Sept. 5, 1960], No. 30542/60. Class 40 (7). Radio direction-finding apparatus for direct use on a chart, comprises a ruler 3, Fig. 4, provided with a locating pin 5 in line with its ruling edge 4 and coupled to a directional aerial 1, for rotation therewith relative to the chart, about the pin. In use, the north of the chart 7 is aligned with the actual north and the pin 5 is stuck in the chart at the location of the beacon which is being received. The aerial and ruler are rotated about the pin to detect a null point and a position line is drawn along the ruling edge. This procedure is repeated with two more beacons to produce a " cocked hat " fix. The aerial may be mounted for rotation externally of the chart room and be connected to the ruler by means of a flexible tube coupling (Fig. 5, not shown). In a second embodiment, Fig. 6, the aerial 30 is free to rotate relative to the ruler and is provided on its mounting with a pointer 32 moving over a scale formed on a protractor extension to the ruler and marked 0 to 360 degrees in an anticlockwise direction. In use the north of the chart is aligned with the axis of the vessel and the aerial is turned to detect a null point. Keeping the aerial still, the ruler and protractor are rotated until the pointer 32 indicates the vessel's heading on the scale. A position line is then drawn along the edge of the ruler. Alternatively the protractor may be mounted on the aerial with the graduations running clockwise, and with the pointer on the ruler.

Title: A process for the production of organic phosphates
Inventor: CADOGAN JOHN IVAN GEORGE
IPC: C07F9/08
Filed: 1960-09-05
Abstract: An organic phosphate of formula Illegible Data wherein R is an alkyl, alkenyl, aryl, alkaryl, or aralkyl group optionally containing inert substituents is obtained by irradiating a phosphite of formula (RO)3P with ultra-violet light in the presence of air or oxygen.  The R groups may be substituted by, e.g. chlorine or bromine atoms, and mixed phosphites, e.g. diethyl benzyl phos phite may be used.  The organic phosphite should preferably be in the liquid state or in solution in a solvent, e.g. benzene, which must be more inert to the action of ultra violet light than the phosphite.  The process can be carried out batchwise or in a con tinuous manner and is preferably effected in a closed system.  The process is generally effected at room temperature or slightly above but in some cases moderate heating or cooling of the reaction mixture may be necessary.  It is preferred that the reaction be carried out under anhydrous conditions and it is particularly suitable to use ultra violet light having a wave length mainly within the range 2700-2800  ngstrom units.  Examples are given for the production of triethyl-, diethyl benzyl, tri-(2-chloroethyl)-, trialkyl-, tri-(2-chloropropyl)-, and tri-(2,3-dichloropropyl) phosphates from the corres ponding phosphites.

Title: Improvements in or relating to digital signal multiplexing systems
Inventor: WHITE COLIN GRAHAM
IPC: H04J3/06
Filed: 1969-06-17
Abstract: 1,246,879. Multiplex pulse code signalling. MARCONI CO. 11 Feb., 1970 [17 June, 1969], No. 30565/69. Heading H4L. In a transmission system wherein a plurality of bit streams are combined in time division multiplex at a transmitting station, each bit stream containing a synchronizing code combination of bits, at least one code combination being distinguishable from the others, the receiver comprises means for demultiplexing the received signals and distributing the resulting bit streams between a plurality of channels, means for detecting the presence or absence of the correct synchronizing code in each bit stream to provide a response pattern indicating the phasing of said streams and means responsive to said pattern to route said streams to the correct output channels. As described the transmitter is identical to that described in Specification 1,176,869 in which each of the four input channels include the same synchronizing code but in the time division multiplexed output the signals in one of the channels, including the synchronizing signal, are inverted. Receiver, Fig. 2.-The input signals are supplied via unit 22 to AND gates 23 to 26 opened in sequence by pulses from a counter 27 controlled by a clock oscillator 28 synchronized with the clock oscillator at the transmitter. The signals appearing at A, B, C, D are correctly demultiplexed but may not be correctly routed and accordingly a re-routing circuit 128 is provided, within which channels A, B, C, D are switched to channels A<SP>1</SP>, B<SP>1</SP>, C<SP>1</SP>, D<SP>1</SP> as required under the control of a code pattern detector 29. The signals at A, B, C, D also control bi-stables 34 to 37 respectively, feeding sync. signal detectors 30, 31, 32 producing an output when the correct sync. signal is detected and detector 33 producing an output when the inverted sync. signal, as arranged for that channel, is detected. Fig. 3 shows the code pattern detected at 29 when the signals are correctly routed, column 1, and when they are one, two and three steps out of phase, columns 2, 3 and 4 respectively. Channels A<SP>1</SP>, B<SP>1</SP>, C<SP>1</SP>, D<SP>1</SP> are connected via AND gates 39 to 42 to the output circuits, the output of AND gate 42 being inverted at 53 to compensate for the inversion at the transmitter. Channels A<SP>1</SP> to D<SP>1</SP> also control bi-stables 48 to 51 respectively, coupled to sync. signal detectors 44 to 47 similar to detectors 30 to 33. The outputs of detectors 44 to 47 are applied to a code pattern detector 43 which applies a signal to open each of the gates 39 to 42 if the correct sync. signals have been detected. If the pattern detected is incorrect, a signal is passed via lead 52 to detector 29 to initiate a further control signal which is passed to re-routing circuit 128 to start a further switching action.

Abstract: 687,223. Locks. YALE & TOWNE MANUFACTURING CO. Nov. 14, 1951 [Dec. 18, 1950], No. 30752/50., Class 44 A cylinder rim night latch has an inside lever handle which actuates a coupling member which is selectively displaced from a position for coupling the handle to a latch operating cam to a position in which it locks the knob to the lock casing, the coupling member being movable to said position by key operated mechanism preferably incorporated in the handle. The lever handle 1, Figs. 1 and 2, is formed to recelve a cylinder plug 2 and is provided with a hollow spigot 6 enclosing a rotary sleeve 16 having a cam groove 15, and the spigot is slotted at 8 to form a seating for a slidable coupling member 9 with teeth 10, 11. The outer tooth 10 is adapted in the normal position to engage in a recess 12 in a rotatable lever-handle cam 13 which operates the spring latch bolt 14. The inner tooth 11 projects into the cam groove 15 in sleeve 16 so that on rotation of the latter, coupling member 9 moves along slot 8 to locked position in which the outer tooth 10 engages a recess 7a in the lock case and prevents operation or the handle 1. Rotation of the sleeve 16 is effected by an eccentric projection 5 on the plug 2 which extends into the sleeve and engages a radial projection 17 (Fig. 6) therein. The lever-handle cam 13 is mounted on the inner end of spigot 6 and held by a circlip 19, and is provided with a tongue 20 located between the ends of a spring 21 housed in an annular groove 22 in the casing. A pin 23 on cam 13 extends through a camming aperture 24 in the bolt lath 25 and into the path of a cover cam 26 operated by the bar 27 of the outside cylinder lock 28. In operation, coupling member 9 is normally in position to couple the inside handle with cam 13 so that the latch bolt can be withdrawn by the handle or by the outside lock 28 on insertion of the key. By key actuation of the handle lock 2 the handle can be locked, and at the same time the cam 13 freed so that actuation of the latch by the outside lock 28 is still possible.
