Abstract: 1,195,784. Strain recorders. R. H. PREWITT [trading as PREWITT ASSOCIATES]. July 31, 1968 [Aug. 21, 1967], No.36555/68. Headings G1J and G1M. Apparatus for recording strains in workpieces susceptible to motions in opposite senses comprises two plates 10, 11 secured to the workpiece, a record receiving member 16 mounted on the plate 10 for movement relative thereto, an element 32 on the plate 11 for recording motions of the workpiece by scratching the member, wires 33 for moving the member 16 in response to motions in one sense and wires 29 preventing movement of the disc during motions in the opposite sense. The two plates 10, 11 are attached to spaced areas 14, 15 of a structure subject to alternating compressive and tensile strains. The plate 10 carries a record receiving disc 16 by means of two rotatable rollers 18 having raised central portions 19 extending into a peripheral groove 17 in the disc 16 and touching the sides but not the bottom thereof. Due to motion of the areas 14, 15 toward one another a bundle of wires 33 (guided by a tube 35 on the plate 10 but secured to the plate 11 by a tube 34) engage the bottom of the groove 17 to rotate the disc 16 anti-clockwise, while clockwise rotation is prevented by a similar bundle 29 during movement of the areas 14, 15 away from one another. Thus a pointed element 32 on an arm 31 fixed to the plate 11 scratches records of successive strains on the disc 16 by radial lines for movements apart and lines oblique to radii for movements together. A recess 38 in the disc 16 prevents more than one revolution thereof. The wires 29, 33 may be metal or glass fibre harder than the material of the disc 16. The element 32 is also harder than the disc 16 and preferably the disc 16, arm 31, plate 10 and rollers 18 are of the same material to ensure the same co-efficient of expansion with change of temperature. A rectangular record receiving member 39 may be used, Fig. 5, (not shown) with a groove 41 receiving a single roller 18 and a metallic friction pad 42.

Title: Removal of polluted air from water closets
IPC: E03D9/05
Filed: 1972-08-07
Abstract: 1400498 Ventilating sanitary closets L BAMBERG 7 Aug 1972 36752/72 Heading E1C A sanitary closet pan 20 or 51 is ventilated by applying suction to the water passage for flushing the pan when the pan is not being flushed, and applying the suction to a separate air passage during flushing, the change-over being effected by a valve having three superposed compartments formed by two partitions in each of which is an opening closable by a valve, the valves being connected to a float in the lower compartment and the lower compartment being connected with a flushing pipe so that when the pan is flushed suction applied to the middle compartment and normally acting via the lower compartment on the water passage of the pan via the flushing pipe is caused to act instead via the upper compartment on the air passage. In one embodiment, Figs. 2 and 4, the air passage 27, having downwardly directed openings 28, is formed in a seat 26 hinged by stubs 29, 30 one of which is hollow and connected via a pipe 31 to the upper chamber 36 of the valve 32. A water passage 22 in the pan 20 is supplied with water by a flushing pipe (24, Fig. 1, not shown) from which a pipe 40 branches at a point downstream of a flushing valve (25) to connect with the lower chamber 39 of the valve 32. Suction is applied to the middle chamber via a pipe 38. Valves 43, 44 mounted on a stem 45 normally occupy a lower position in which opening 41 in partition 34 is closed and opening 42 in partition 35 is open, so that suction is applied via pipe 40 to the water passage 22. When the closet is flushed, water enters compartment 39 and acts on float 48 to raise the valves 43, 44 so that opening 42 is closed and opening 41 is opened so that suction is now applied via pipe 31 to the air passage 27. In a modification, Fig. 6, the air passage 54 is formed in the pan 51 adjacent water passage 52 and the downwardly directed openings 55 in the air passage are on the same level as discharge openings 53 of water passage 52, but may alternatively be below the latter openings (Fig. 8, not shown). In a further embodiment, Fig. 11, the valve is modified in that movement of the float is assisted by the action of flushing water on a cup 100 acting through linkage 97, 98, 99 on stem 95 carrying the float 96 and valves 93, 94.

Title: Improvements in or relating to x-ray spectrographic analysers
Inventor: PRICE BRIAN JOHN
IPC: G01N23/207
Filed: 1964-09-11
Abstract: 1,116,865. X-ray spectrometers. ELLIOTT BROS. (LONDON) Ltd. 10 Sept., 1965 [11 Sept., 1964], No. 37191/64. Heading H5R. [Also in Division G1] Photo-electric spectrometer apparatus comprises a casing 4 for an X-ray generator 2 and a plurality of segmental housings arranged in an arcuate array around the generator casing, each housing containing at least one spectrometer channel for the analysis of one element. The generator casing 4 is generally cylindrical is shape and has an aperture 10 in the base against which a sample holder is located. X- rays from the tube 2 are back-scattered from the sample and, by virtue of the shaping of the aperture 10, directed as a 180 degrees fan towards the array of six segmental housings which are arranged along one wall of the casing 4. Each housing has two apertures 9, provided if required with windows, for entry of X-rays into two collimators aligned with the apertures. One collimator 63 directs the rays on to an analyser crystal 50, from which they are reflected to a scintillation counter contained within its casing 51 mounted on top of the segmental housing. The other collimator directs X-rays via another crystal to a proportional counter 35 mounted inside the segmental housing. The latter crystal is angularly adjustable by means of a knob 46, the settings of collimator 63 and crystal 50 being adjustable by screws 68 and 61, respectively, while the position of the scintillation counter 51 can be moved angularly by means of its U-section bracket mounting 52. In the examination of a solid sample, a window may not be required in aperture 10, but when a liquid or slurry sample is tested a nylon thread reinforced plastics window is provided, this being part of a sample flow cell 13. The cell has inlet and outlet passages leading to and from a test chamber (Figs. 4, 5, not shown) and sealing means, together with an entry bore for lubricating fluid which prevents the erosion of the window surface by the abrasive action of the flowing sample. The apparatus is particularly adapted to examine a sample for the presence of a plurality of elements, one being evaluated by the apparatus in each segmental housing. The atmospheres in each housing (including the X-ray generator compartment) may be different or a vacuum. The outputs of the scintillation and proportional counters are handled as required. A plurality of samples or a very large one can be located beneath the aperture 10. The sample presentation apparatus may be modified to provide for measurement of X-rays transmitted by a sample. A method of constructing collimators for the apparatus, is described.

Title: Facsimile Communication System.
IPC: H04N1/413
Filed: 1967-08-14
Abstract: 1,181,528. Pictorial communication bandwidth reduction. XEROX CORP. 14 Aug., 1967 [15 Aug., 1966], No. 37248/67. Heading H4F. Video signals derived by scanning a document are: (1) converted to binary signals by limitation and time quantization under control of a clock, (2) translated into coded binary signals indicating the essential data and redundancy and (3) finally converted to variable frequency audio tone signals suitable for translation over a telephone network of limited bandwidth. A converse process is employed during reception to re-establish a signal suitable to operate a recorder. The coding of the signals takes place in two steps. The first involves the comparison of the binary signals due to successive line scans of the document so as to determine the difference. This eliminates the redundancy due to vertical correlation in typical written and typewritten documents. The resulting signal, which has a reduced number of black data bits but an increased number of white data bits, is then subjected to the second step which is based on U.S. Patent 3,035,121 and involves the production of binary numbers representing the run lengths of black and white bits. The translation to the audio frequency signal is effected by converting the coded binary signal to a fourlevel signal in which a different level is allotted to each of the four possible combinations formed of two successive binary bits. The fourlevel signal then controls a frequency modulator to produce an audio frequency signal consisting at each instant of one of four possible tones. The production of the initial binary signal is at a rate exceeding the transmission capability of the telephone network and the apparatus includes a buffer store with means for interrupting the document scanning if the store becomes overloaded. Provision is made to detect the ends of the document lines and to insert a synchronizing binary signal in the signal train. The invention is described in relation to unitary send/receive apparatus with provision for supervisory control between two stations. Means are provided to interrupt pictorial transmission to allow voice communication. The apparatus may be connected to the telephone network directly, although the particular arrangement described makes use of acoustic couplers. Interlock facilities are provided to ensure that the apparatus cannot be put into use until such elements as the acoustic coupler are engaged properly. Scanning of the original document is effected by a rotating optical head, whilst reproduction is effected by a xerographic technique using either a cathode-ray display or high-voltage recording elements carried on the same member as the optical head. Reference is made to the use of phase compensation at a receiving station to allow for distortion in the telephone network, and the provision of means to establish bit synchronization for a clock source from the received binary signals.

Abstract: 363,808. Thermally-actuated mixing valves. BECKER, H. R., 39, South Lander Street, Newburgh, New York, U.S.A. Dec. 11, 1930, No. 37378. [Class 135.] A thermally-actuated mixing valve has a valve member adapted to be rolled over a ported seat by a bimetallic thermal element. A seat member 10 having a curved contacting surface with narrow rectangular inlet ports 22, 23 is secured in a cylindrical mixing chamber by a tapered projection 15 engaging a pocket 17 and by a clamping screw 20, so as to connect the ports 22, 23 to the hot and cold water inlet pipes 6, 7 by way of passages 4, 12 and 5, 13. The valve member 25 which has curved contacting surfaces covered by a packing 27 secured by plates and screws 29 carries a transverse rod 32 rotatably mounted in a yoke 37 pivoted at 38, 39 to the seat. The holes in the yoke are slightly larger than the rod so that the valve may be firmly pressed against its seat by screws 40, 41. To prevent the valve member slipping over its seat it is provided with a pair of projections engaging corresponding recesses in the seat. The thermal element is formed of laminated plates 54, 55 each composed of metals having different coefficients of expansion and is anchored at one end 88 to a yoke 44 pivoted to the seat and connected at the other end by a yoke 48 to the pivoted member 37. The plates are spaced apart and holes 56 are provided to bring the fluid into intimate contact with the element. The yoke 44 has a roller 57, engaging a cam slot 63 in a plate 62 adapted to be rotated to adjust the device to the required temperature. The plate 62 is carried by a spindle 61 rotatably mounted in a boss 59 on a detachable cover 2 and packed by a stuffing-box having a gland 65 formed integrally with a cap screw 64. A plate 68 having a projection 74 adapted to work between adjustable stops on the front cover has a hollow boss 70 surrounding the cap screw 64 and is coupled to the spindle 61 by the adjusting handle. To facilitate the adjustment of the stuffing-box the hollow boss 70 has a hole 90 through which a pin may be passed to engage recesses formed on the cap screw to look the cap screw to the adjusting handle. The adjusting handle has a pointer adapted to co-operate with a dial formed on a plate secured to a wall in front of the device. Baffles 79, 80 are fitted to the valve seat to facilitate the mixing of the fluids.
