Title: Rocking struts
IPC: B61F5/02
Filed: 1950-09-19
Abstract: 684,521. Struts. BEZOLD, H. VON, and KILB, E. Sept. 19, 1950 [Sept. 23, 1949]. No. 23016/50. Class 20 (ii). [Also in Group XXXII]. A strut 1 for bridges, railway vehiclewheel assemblies, &c. is rockable in at least one plane and has at each end arcuate surfaces 2 which may have a common centre and engage parallel surfaces 3 on bearing members 9, each having a curved guiding surface 5 engaging a flat guiding surface 6 on the strut to constrain the ends 2 of the strut to roll on the surfaces 3 without slipping. The bearing surface 5 may be a surface of revolution with a cylindrical curve as generator and the surface 6 may be cylindrical as shown. The rocking of the strut is limited by the engagement of a ring 4 on the bearing 9 with a conical surface 12 on the end of the strut. Elastic bellows 10 retain lubricant. A modification is shown in which the curved surface is on the strut and the cylindrical surface on the bearing 9 which arrangement is also shown in Fig. 3, which also comprises a strut formed of two telescoping parts 14, 15, and in which the supporting force is transmitted by a spring 16. When the strut rocks in one plane only the surfaces 2, 5, 6 are formed by rectilinear generators.

Title: Improvements relating to the provision of a design on a textile material
IPC: B41F17/00
Filed: 1929-07-26
Abstract: 341,931. Ornamenting textile materials. HUDSON, G. R., 9A, Margaret Street, Cavendish Square, London. July 26, 1929. No. 23021. [Class 100 (ii).] Textile material is colour embossed or coloured by placing it upon a moulded or blocked surface, superposing a moistened sheet, and applying pressure by means of a heated platen, the appropriate parts of the moulded or blocked surface having been previously covered by a dye soluble in the liquid employed for moistening the sheet. The dye is thus carried into the textile material, spreading of the dye being prevented by the provision of perforations in the mould or block to permit the escape of the generated vapour. The edges of the design may be formed as small grooves on the mould surface, and the perforations formed transversely to the grooves, channels being provided at the back of the mould to carry away the vapour generated. According to the Provisional Specification, simple embossing may be effected by placing the textile on a perforated embossing-surface, covering with the moistened sheet, and then pressing with a heated platen. Specification 317,578, [Class 100 (ii), Printing processes &c.], is referred to.

Abstract: 963,933. Packaging-machines; endless conveyers. OTTO HANSEL Jun. G.m.b.H. June 15, 1962, No. 23038/62. Headings B8A and B8C. Chocolate bars 1 are fed to the folding box 9 of a wrapping machine by means of an endless conveyer 2, 2<SP>1</SP>, the conveyer members 2<SP>1</SP> extending as shown in Fig. 2 to form a feed grating so that the bars 1 may be lifted from the grating by a reciprocating member 12 from which they are transferred to a second grating 10 by a pusher 24. As the leading bar 1 reaches the grating 2<SP>1</SP>, it operates a switch 27 to release a detent 31 enabling a spring-urged member 13 to rise in contact with the groove of a cam disc 17. Lateral movement of the member 12 is effected by a crank 21. As the member 12 is withdrawn, a folding member 6 moves upwards to force the bar 1 and its wrapping paper through the box 9. The machine operates continuously so long as further bars 1 are fed forward, but the detent 31 automatically halts it if no feed takes place.

Title: Improvements in apparatus for indicating the quotient or product of two quantities
IPC: G06G3/00
Filed: 1932-08-17
Abstract: 406,309. Calculating-apparatus; speedometers; indicating-apparatus; weighing- apparatus. PEARSON, J. L., 2, Bank Road, Billingham, Stockton-on-Tees. Aug. 17, 1932, No. 23043. [Classes 106 (i), 106 (iii), and 106 (iv).] Apparatus for indicating the product or quotient of two factors comprises two cylindrical or right-conical surfaces carrying logarithmic curves, one of the surfaces at least being moved by some exterior mechanism, the curves co-operating with a fixed reading edge in such a manner that the required result can be read off one of them. The embodiment described is used for determining the mean speed of a vehicle. An inner cylinder A is rotated in accordance with distance travelled and has around its edge a scale B of miles. If an axial line is taken on the surface of the cylinder then the logarithms of distances are marked off on this line in such a manner that the last mark has the same value as the point with which it coincides on the scale B. This is repeated for a number of axial lines all round the cylinder and the corresponding points are joined to form curves C which are marked with figures representing speeds. An outer transparent cylinder F is rotated by clockwork and has a logarithmic curve H related to a time scale G. A second curve J, similar to the curve H but for a different range, is also marked on the cylinder F in a colour different from that of the curve H. The cylinder A is placed inside the cylinder F in a casing M and the curve C which happens to be intersected by the curve H (or J) at a fixed reading edge O indicates the required speed. An ordinary speedometer is observed through an aperture V, the distance scale B through an aperture R, the time scale through an aperture S and actual time through a window T. The shafts P and Q of the drums are connected to their driving means through clutches and the scales may be illuminated by a lamp placed inside the cylinders. The apparatus is stated to be applicable to fuel-consumption meters, watt meters, altimeters, and price-and-yardage and price-and-weight machines.
Patent GB-1404509-A (GB)
Title: Apparatus for and a method of packaging articles in bags
IPC: B65B31/04
Filed: 1973-05-15
Abstract: 1404509 Vacuum-packaging apparatus W R  GRACE & CO 15 May 1973 [1 June 1972] 23126/73 Heading B8C Vacuum-packing apparatus comprises a rotating turret 4 mounting a plurality of vacuum nozzles 6 each adapted to support and evacuate a filled bag during rotation of the nozzles, and an oscillatable clipping and severing mechanism 14 adapted to rotate with each nozzle for a portion of nozzle movement and to clip seal and sever the moving bag from the nozzle whilst in motion. The turret shaft 3, Fig. 2 (not shown), is driven by a motor through gearing 19 and 20, and the clipping and severing mechanism is carried on a support member 17 and arm 63, which are oscillated about the turret axis by a crank and pinion connection 21 and 22 to the turret drive to move in synchronism with each nozzle over a portion of nozzle movement. The operation of the clipping and mechanism is automatically effected through a series of cams 30, 31 and 32 and pneumatic switches. Each nozzle comprises non-aligned upper and lower sections 54 and 56, which have co-operating flanges 73 and 74 held together by rubber bands 72, and a surrounding clamping barrel 71 which is biased upwardly from the flanges by an interposed spring 55. When an operator applies the neck of a filled bag about the barrel of a respective nozzle, the lower and angled nozzle section is swung into a vertical position thus parting the flanges to allow vacuum to be applied to the inside of the barrel and to the bag through the lower nozzle section by way of port 62. The vacuum inside the barrel causes the latter to move downwards against the spring bias to grip the bag against a resilient nozzle element 58, Fig. 4 (not shown). In a modification, Fig. 4b (not shown), the flanges are resiliently held together by a spring 80 and vacuum is fed to the barrel interior through a passage 77 when the nozzle sections are aligned on loading by the operator. In the arrangement of Fig. 6a, the filled-bag infeed conveyer 65 also acts as sealed bag discharge conveyer. In a modification, Fig. 6b (not shown), two parallel countermoving conveyers are used. The clipping and sealing mechanism may be provided with a guide arm 70, Figs. 7a, 7b (not shown), to assist the operator in ensuring that the bag contents are pushed to the bag bottom when loading a nozzle.

Title: Electronic device for maintaining the scanning raster of a flying-spot scanner in register with the film frames
Inventor: WHITLOCK IAN LOADER
IPC: H04N3/36
Filed: 1951-10-05
Abstract: 714,345. Photo electric control system. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. Sept. 11, 1952 [Oct. 5, 1951], No. 23271/51. Class 40 (3) In a device for maintaining the raster of a flying spot film scanner in register with the frame, means are provided for projecting a patch of light on to a part of the film which includes at least a part of a sprocket hole, light reflected from this part producing in a detector an output which depends on the relative position of the sprocket hole and the patch of light and is used to adjust the position of the scanning raster. As shown, the scanning raster is produced by a cathode ray tube and is imaged on to the film plane FP. The light spot which i'luminates the sprocket hole is produced by an auxiliary cathode ray tube AT and the overlapping portions A, B, and sprocket hole SH are shown in Fig. 4. Photo-electric cells PE<SP>1</SP>, PE' each receive light from one of the areas A, B, and feed a differential amplifier DA the output of which is applied to a servo system SS to adjust the light patch relatively to the sprocket hole and at the same time the position of the scanning raster of tube F.S. In a modification (Fig. 2, not shown) the cathode ray tube AT is replaced by a small projector lamp, light from which is reflected into the region of the sprocket hole by a mirror the angular position of which is adjustable. The mirror may be carried by a loud speaker speech coil. In a further embodiment (Fig. 3 not shown) the beam produced by cathode ray tube AT oscillates across one edge of the sprocket hole thus producing in a single photo-electric cell a number of square pulses whose width depends on the degree of overlap of the trace with the hole, and whose average value varies in sense and magnitude according to the duration and extent of misalignment.

Abstract: 1379658 Automatic tuning control in radio systems MARCONI CO Ltd 19 May 1972 [21 May 1971] 23551/72 Headings H3A and H3Q An automatic tuning arrangement for a filter 10, e.g. in a radio link, comprises: means for applying a sweep voltage to sweep the centre frequency of the filter through a predetermined range; means 18 for additionally applying an A.C. signal to cause a corresponding variation about the centre frequency determined by the sweep signal; means 66, 82 for detecting an amplitude modulated signal exceeding a predetermined level at the filter output and stopping the sweep when level is exceeded; and means 74 for detecting amplitude modulation at the frequency of the A.C. and for controlling the tuning to reduce this to a minimum. The sweep signal is generated by a 3 Hz pulse generator 24 whose output is fed via gate 26 to a counter 28, 30, 32, 34 whose outputs are suitably weighted by 44, 46, 48, 50 and fed to a summing point 22 to produce a staircase signal which controls varactor diodes in the filter 10. The A.C. modulating signal or 100 Hz pulse generator 18 is also fed to summing point 22, as are potentials on lines 56, 58 for setting the starting point of the sweep. The staircase signal sweeps the passband of the filter until a received signal is sufficiently near the centre frequency for the threshold of unit 82 to be exceeded, whereupon the output from 82 closes gate 26 to stop the sweep. The detected 100 Hz modulation signal from the filter output is then fed via filter 70 to a synchronous detector 74 where it is compared with the original 100 Hz signal to produce a control signal for the filter to bring its centre frequency into coincidence with the received frequency.
