Title: Improvements in sewage distributors
IPC: C02F3/04
Filed: 1922-09-22
Abstract: 205,656. Hartley, J. W., and Hartley, C. J. Sept. 22, 1922. Rotary apparatus for distributing sewage to a circular filter bed comprises a distributing arm and a balancing arm oppositely arranged and rotatably mounted upon and suspended from a central supply column A by means of sling ropes T, O. passing over pulleys or quadrants V, W. The distributing arm rests upon a circular track while the balancing arm is pivoted at Q, R and is raised and lowered as the sling ropes expand or contract while the distributing arm remains at a constant level. The distributer is driven by means of a water wheel C supplied with sewage through the pipe D. The shaft of the water wheel carries a roller M which either rests on the track or, as shown, rests on two wheels L which drive on the track either by friction or toothed contact. The wheel C discharges into the perforated distributing trough G and is preferably mounted on thedistrihutor arm at a point which divides the area to be sprayed into two equal parts. The track may be slightly eccentric around the central column to give even wear to the wheels. The distributer arm is supported by means of laterally braced steel channels O which together with the feed pipe B bolted to the channel by brackets P form a rigid structure with the trough G. The balance arm is lighter than the distributer arm in order to give sufficient friction between the wheels and the rail, the amount of pressure being adjusted by means of a trough S. Where the filter bed is built up without a retaining wall an inner circular track G' is formed as shown in Fig. 7, and the arm supported on the track by a carriage E<1> carrying two runner wheels A<1>, A<2> one of these being driven by means of a spur wheel D<1> engaging a pinion keyed to the water wheel shaft. Specification 20060/14 is referred to.
Patent GB-893712-A (GB)
Title: Improvements in coin-controlled vending machines
IPC: G07F11/50
Filed: 1960-07-22
Abstract: 893,712. Coin and check freed apparatus. WITTENBORG, E. July 22, 1960 [July 24, 1959], No. 25663/60. Class 27. The locking mechanism of a drum-type vending machine comprises a fork 8 having a notch engaging a single lug 4 or 5 of a ring of lugs on the drum and the fork is movably mounted on a member' 15 which, on the correct insertion of coins, causes the fork to be released momentarily from the lug. As shown in Fig. 3, a frame 40 carries both the locking lever 15 and the advancing roller 3 for one of several drums arranged one above the other, the roller 3 being coupled by a clutch 26 with a sprocket 28 driven by a chain common to all the drums. The fork 8 is slidably mounted on the lever 15 by pins 43, 44 and a slot 42 and is loaded by a spring 46. When the correct number of coins has been inserted and a drum selector pushbutton depressed, an electromagnet 11 corresponding to the drum is energized and through a link 36 the lever 15 is turned about its pivot 25 to withdraw the fork 8 from the lug 5. The spring 46 then moves the fork along the lever so that its tail operates a switch 49 and causes an electromagnet 30 to be energized. The armature 31 of the electromagnet 30 moves a lever 27 to engage the clutch 26 and allows a switch 52 to close so that a circuit is established to the chain driving motor. The electromagnet 11 is de-energized by operation of the switch 49 and has released the lever 15 for return by a spring 41 so that the next lug 4 on the rotating drum meets the inclined surface 22 of the fork 8 and, after slipping into the notch, pulls the fork against the action of the spring 46 to release the switch 49. The driving motor and electromagnet 30 are thus de-energized, the clutch 26 is disengaged and the coin mechanism is returned to neutral position. In a modification, applicable to a singledrum machine and shown in Fig. 1, the fork 8 is formed on a lever pivoted at 13 on the sliding armature of the electromagnet 11. On momentary energization of the electromagnet by a coin 9, the fork is pulled away from the lug 5 and a spring 77 rocks the fork lever so that its arm 18 closes a contact 19 and energizes the motor 9, which is directly connected to the roller 3. The contact 19 is held closed until the next lug 4 falls into the fork.

Filed: 1971-04-19
Abstract: 1316003 Centrifugal compressors NETHERLANDS APPLIED SCIENTIFIC RESEARCH FOR INDUSTRY TRADE & COMMERCE 19 April 1971 [7 April 1970] 25721/71 Heading Fl C A centrifugal fluid vane type compressor comprises a rotor 3, Fig. 1, surrounded by a chamber 11 supplying working fluid substantially tangentially to the rotor through guide blades 13. The working fluid discharges from the rotor through outlets 19 to form fluid vanes which compress another fluid, e.g. air, delivered via inlet 7 and blades 6. The mixed fluids are delivered via collecting channel 22 into a reservoir 2 where the compressed fluid is separated from the working fluid by partitions 23, and passes to outlet 24. The working fluid is recirculated from the reservior to the chamber 11 by pump 16 and control means 15. In an alternative embodiment, Fig.3 (not shown), a pump impeller (25) is formed integrally with the rotor (3) to deliver working fluid thereto. The walls 20, 21 may diverge in the direction of flow. Alternatively, one or both walls may freely rotate with the rotor, and the periphery of the space defined therebetween may have blades which are interconnected by a wire mesh screen.

Filed: 1946-08-28
Abstract: 620,058. Nursery chairs. MULLER, R. C. Aug. 28, 1946, No. 25729. Convention date, March 17, 1945. [Class 52 (ii)] [Also in Group XV] A convertible chair for babies comprises two parts, a chair section and a support section, connected so as to either pivot or be easily separable. While connected, the parts form either a high chair or a chair with play-table and while separated a low chair and a separate device for packing. When arranged as a high chair, the chair is supported on aligned legs 1, 2, the two parts being detachably pivoted at the front legs by tapered sockets 14 embracing pins 13 connected by levers 6, 7, 8 to an operating handle 11. The parts are locked together by latches 17 at the rear legs, urged rearwardly by a spring 20. When arranged as a chair with play table (Fig. 4), the latches 17 are released and the lower part swung through 180‹ and locked by hooks 27 in the extended position, the play table being formed by a board 23. To separate the members the handle 11 is operated, withdrawing the pins 13 from their sockets 14. The upper member then forms a low wheeled chair and the lower part a baby-walker fitted with a table 29 with play-balls 31, a harness 32 and running on wheels. The chair is fitted with a tray 36 and an adjustable footrest 24.
Patent GB-600422-A (GB)
Title: Improvement in radio frequency transmission lines
IPC: H01P1/18
Filed: 1945-10-03
Abstract: 600,422. Coaxial transmission lines. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. Oct. 3, 1945, No. 25766. Convention date, March 29, 1943. [Class 40 (viii)] A device for the adjustment of a length of coaxial line consists of three concentric conductors, the middle and inner being connected to the input transmission line and the middle and outer to the output transmission line, the inner conductor being connected to the outer by means of a movable shorting plug whose movement telescopes the two inner conductors. As shown, Fig. 3, the input line 1, 2 is connected to the telescoping coaxial line comprising outer conductors 3, 17 and inner conductors 4, 16, and the output line is connected via the tapered matching portion 14, 15 to the coaxial line comprising the outer conductor 7 and the middle conductor 3, 17. Conductor 16 is connected to the adjustable shorting plug 18 and conductor 17 is fixed to the plug by an insulating block 18 or by a quarter-wave conductor. Arrows indicate the energy transfer path, whose length is varied by the adjusting screw 24. The cylinder 7 is supported by cylinder 8 and plugs 9 and 14, the former being adjusted by knob 44 to constitute with conductor 1 a quarter-wave line. Tuning of the input line is achieved by a quarter-wave line having a shorting plug 58 adjusted by knob 59. Similar tuning of the output line is achieved by the shorting 65 adjusted by knob 54. In a modification not incorporating the variable tuning, conductor 17 (and also conductor 16, if desired), may be extended through the bottom of the device and be controlled from there, so eliminating the necessity for the insulating block 19. The degree of telescoping may be controlled independently of the position of the plug 18, Fig. 2 (not shown), so that the coupling between the input and output circuits due to the air gap between the top of conductor 17 and the plug 18 may be varied. This in conjunction with the variable tuning of the input and output circuits mentioned above permits the device to be used as a band-pass filter. A more compact but less rigid construction, Fig. 4 (not shown), omits the input and output tuning stubs.

Title: Phase Comparison Circuit
IPC: H04N5/12
Filed: 1967-06-05
Abstract: 1,196,325. Automatic phase control circuits. R.C.A. CORPORATION. 5 June, 1967 [14 June, 1966], No. 25902/67. Heading H3A. A phase comparison circuit for a television receiver comprises: a deflection circuit 27 producing a recurring deflection waveform having trace and retrace portions; an oscillator 23 driving the deflection generator and producing a reference pulse at the start of the retrace portion of the deflection waveform; and a control circuit 25 arranged to receive the reference pulses and received synchronizing pulses and to produce a control signal, dependent on the interval between leading edges of the reference and synchronizing pulses, but independent of the pulse widths, which is fed to the oscillator 23. The circuit is arranged such that initiation of the retrace portions of the deflection waveform occur prior to the synchronizing pulses. Oscillator 23 is in the form of a multivibrator producing rectangular output pulses which trigger the deflection generator. These pulses are differentiated in circuit 30, to produce positive and negative-going pulses applied to the base of transistor 21, the positivegoing pulses corresponding to the start of the retrace portions. Synchronizing pulses produced by circuit 17 are shaped by circuit 20 to produce negative-going pulses which are also fed to the base of transistor 21. Transistor 21 is turned on by the leading edge of the positive pulses from circuit 30 and is turned off again by the leading edge of the negative pulses from circuit 20 to produce across integrator 25 a voltage proportional to the time during which transistor 21 is on. This voltage varies the frequency of oscillator 23.

Title: Improvements in or relating to Dial-Operated Data Exchange Systems
IPC: H04L12/00
Filed: 1968-05-30
Abstract: 1,186,643. Digital transmission systems. SIEMENS A.G. 30 May, 1968 [31 May, 1967], No. 25904/68. Heading H4P. In an exchange system when an exchange receives a series of dialling signals it compares the first signal with a set of element combinations and transmits the subsequent signals to a destination dependent on the result of the comparison. The comparison is effected bit by bit. In one example, Fig. 3, an exchange receives dial signals Ek. The first signal 1WZ is inspected to determine whether it is one of a given set of signals. Each signal in the set is one that begins an address which will lead, in the exchange itself, to a clear determination of the route. It is first assumed that by the time (t2) the third bit has been inspected it is recognized that 1WZ is not in the set, so the dialling signals must be passed to the next higher exchange. The lower exchange calls the higher (line Sg, t2-t5), and the higher acknowledges the call (line Eg, t3-t4) and at t4 returns a dial signal call-up signal W Auf. At t5 the lower exchange recognizes the call-up signal and then transmits the dialling signal to the higher exchange. If, on the other hand, the signal is one of the given set the exchange seizes the required line and subsequently switches to it. The exchange is then cleared. This occurs prior to reception of the second and subsequent dialling signals, which are thus passed to the selected line. Alternatively, where the higher exchange is required the line to that exchange is seized immediately this fact is determined, and the dialling signals are passed to the higher exchange but with shortened stop bits, Fig. 5 (not shown). Eventually one of the signals will have been transmitted in its entirety before the reception of the next signal to be transmitted. When this occurs the connection is switched through the lower exchange, and the exchange cleared, prior to transmission of that next signal.

Abstract: 836,889. Sanding. PENDERGAST, R. F. Aug. 24,1956. No. 26041/56. Class 60. A sanding or like machine comprises a frame having mounted thereon a contact roll and a second roll, an endless working belt entrained over said rolls, means for rotating one of sand rolls so as to create an approach flight of the belt to the contact roll, and means adjacent each edge of the approach flight of the belt for redirecting the belt toward the centre of the contact roll should the belt move laterally of the roll. A sanding machine, particularly for objects of irregular shape such as a hide 38, comprises a sanding belt 34 entrained over rolls 20 22 carried by uprights 12, 14 within housing 10. The contact roll 20 has a helically grooved rubber sleeve 23 and is driven by a motor to impart to the belt a linear speed of 3000-6000 ft. /min. ; a pressure roll 24 within housing 26 co-operates with the contact roll 20. The inclination of the shaft of idler roll 22 with respect to the shaft of the contact roll 20 is adjustable by a member 28 so as to centre the belt 34 before sanding begins. The uprights 12 14 carry inwardly directed brackets 42, 44 on each of which is pivotally mounted an arm 58 having secured thereto by screws 70, 72 a blade having a convex surface 66 ; in a modification, the blade is replaced by a roller 80, Fig. 9, mounted for free rotation on a shaft 82 on the end of the arm 58. The blades are positioned so that they are out of contact with the edges of the belt 34 when the latter is central on the rolls. When a hide is introduced between the contact roll and pressure roll, the belt may travel laterally until one edge engages the blade or roll, the resultant tightening of the edge causes the belt to move back towards central position.
