Abstract: 1,192,087. Oil filter. PUROLATOR Inc. 21 June, 1967 [22 July, 1966], No. 28633/67. Heading B1D. An oil filter of the screw-on type, for use in the lubricating circuit of an I.C. engine, composes an end closure consisting of a comparatively thin walled cover 25 backed by a thicker reinforcing plate 24, both having aligned inlet apertures and a central outlet opening, and cover 25 receiving an annular sealing gasket 28 in a groove whose floor is spaced from plate 24 so that the resilience of the cover can accommodate misalignment of the filter on the engine block. The cover has tubular extensions 25d which are flared outwards within openings 24c to secure the cover and plate together, and sealing compound may be applied between plate 24 and inner band 25b of the cover. Annular anti-drain valve 26 is backed by a spring plate 27. A by-pass valve 17 is fitted within pleated, paper filter element 12, which is urged on to outlet coupling 24d by leaf spring 22. Element 12 is supported by an internal perforated tube 16 which may have annular corrugations with the perforations in their inner floors.

Title: Improvements relating to mechanism for feeding webs
IPC: B65B41/16
Filed: 1948-11-05
Abstract: 652,834. Wrapping - machines. CAMPBELL, S. J. Nov. 5, 1948, No. 28812. [Class 94(i) [Also in Group XVI] Mechanism for laterally spacing parallel and coplanar strips of material cut longitudinally from a common web while maintaining the relative longitudinal positions of portions which were contiguous in the web includes a first spreader member over which said strips pass to change laterally their direction of movement, and a second spreader member positioned in the path of the strips leaving said first spreader member and over which second member said strips pass with a lateral change of direction which restores parellelism and coplanarity to the respective strips. As applied to a wrapping machine, wrapping- strips 70, 71, 72, 73 are cut longitudinally from a web fed from a roll 55 past a'light source 57 and photo-electric cell 58 which synchronizes the movement of the web and articles 40. The web is slit longitudinally by knives 60 and the individual strips 70-73 pass over a spreader member 62 having inclined rounded guiding surfaces 65 and 66 and rounded guiding surfaces 67 and 68 which deviate at greater angles than the former surfaces from a line normal to the vertical plane through which the longitudinal machine axis passes. A spreader member 63 mounted above the member 62 is provided with surfaces 75, 76, 77, 78 similar to and offset outwardly of the surfaces 65, 68. In passing over the member 62 the strips are caused to move angularly outwardly away from each other, but in passing over the second member 63 they will be restored to parallelism and coplanarity and will be spaced from each other far enough apart to permit them to be manipulated individually with respect to the articles. The articles 40 to be wrapped are supplied by a belt 38 on to converging shoots 39 and are fed forwardly by fingers 43 depending from an overhead conveyer (not shown). The wrapping-strips 70, 71, 72 and 73 are fed over a roll 79 upon which glue-rolls 80 apply glue to the margins of the strips, past the ends of the shoots to receive the articles 40, the entubing of the articles being completed between conveyer belts 84 and 85 and folding-blades (not shown) after which the strips are severed transversely between the entubed articles. In a modification the strips may be spaced apart by passage over spreader members comprising pulleys. Specification 652,833 is referred to.

Abstract: 825,508. Spectrometers. PARSONS & CO Ltd., Sir H. G. Aug. 30, 1957 [Sept. 21, 1956], No. 28969/56. Drawings to Specification. Class 97(1) [Also in Group XL(b)] In a grating spectrometer, the elimination of second and higher order spectra is effected by additional gratings which are arranged to produce the successive orders at the same strength as the main grating. By chopping the radiation from the main grating over one half of a cycle and the other gratings over the other half, a steady output of radiation in the second and higher orders is obtained while a fluctuating output in the first order is obtained and recorded by a photo-cell and amplifier. The gratings may have different spacings and be arranged one above the other or side by side and the output may be chopped by a gapped cylinder or disc respectively. Alternatively, the gratings may have the same spacings and be arranged one above the other, but with their faces differently inclined.

Title: Measurement of linear distances
Inventor: COOK ALAN HUGH
IPC: G01B9/02
Filed: 1964-07-17
Abstract: 1,076,991. Measuring distance optically. NATIONAL RESEARCH DEVELOPMENT CORPORATION. July 19, 1965 [July 17, 1964], No. 29321/64. Heading G1A. A distance is measured by modulating the frequency of a coherent light source, directing a fuse beam from said source over a path of known length through an interferometer, directing a second beam from said source over a distance to be measured through said interferometer, adjusting one of the parameters controlling the relative frequencies of the two light beams on arrival at a detection point at the end of said paths to bring said two frequencies to equality and measuring the extent of such adjustment. The adjusted parameter may be one of the optical paths or the frequency of modulation. In the form shown the cavity of a gas laser L is bounded by end mirrors M 1 , M 2 , the former being driven by an oscillator O to modulate the emitted frequency. The light enters a two-path interferometer, D 1  being the distance to be measured, D 2  a known distance. Beams from the recombining mirror M 3  differ in phase because of phase change on reflection but will, in general, both contain the modulation frequency as a component. The two beams fall on photo-multipliers P 1 , P 2  connected to a differential amplifier A 1  the output of which drives the mirror M 1  to vary the mean laser frequency to maintain a constant phase difference between the beams traversing the paths D 1 , D 2 . The output of P 1  is fed also to a superheterodyne detector A 2  the oscillator of which is varied in step with the oscillator O which is adjusted so that a null output is obtained from the detector. By selecting successive values of the frequency of the oscillator O which give a null output a value for D 1  can be obtained in terms of D 2 .

Abstract: 915,735. Circuits of bi-stable magnetic cores; automatic exchange systems. STANDARD TELEPHONES & CABLES Ltd. Aug. 26, 1960 [Aug. 29, 1959], No. 29584/60. Classes 40 (4) and 40 (9). A ferrite core is provided with an additional winding which is short circuited when it is desired to suppress read-out from that core. The arrangement facilitates the use of common control circuits for semi-permanent and highspeed stores. As shown, three matrices S1, S2, S3, each have one core, K1, K2, K3, relating to the same subscriber in a telephone exchange. Matrix S1 relates to semi-permanent information such as class of service, and matrices S2, S3 relate to high speed information such as the condition of the subscriber's line, or an accruing fee. The cores are written into and read-out is affected by simultaneous application of pulses to row and column wires 1, 2. Individual readout circuits 3/1 ... 3/3 are provided one for each matrix. Matrices S2, S3 may be provided with additional windings for the application of suitable inhibiting pulses to control their operation. The cores of matrix S3 are all set by the write in pulses. Read-out however is dependent on whether or not the additional windings 4 are short-circuited. This may be effected by plugs or soldered connections, or from a distance by means of switches such as relays or transistors. The loops 4 may be formed by a single wire threading the cores of a row and brought out to terminals between each pair of cores, Fig. 2 (not shown).
