Title: Apparatus for checking the circumferential edge surface and the diameter of disc shaped objects
IPC: C22B3/00
Filed: 1970-12-10
Abstract: 1331976 Checking disc-like objects GRANGES ESSEM A B 10 Dec 1970 [ 23 Dec 1969] 58762/70 Heading G1M [ Also in Division G4] Apparatus for checking the circumferential edge surface and the diameter of disc-like objects 24 such as coin blanks comprises on arcuate chute 17 made up of a stationary arcuate guide 18 and a rotating pulley 23 having a tapered groove 37. Objects to be gauged are fed one at a time from delivery chute 10 into the arcuate chute 17 and correct objects are carried around chute 17 to exit chute 22 by the rotation of pulley 23. Pulley 23 is movable axially against spring 35 and a correct object causes the pulley to be moved upwardly to the position shown in figure 2 in which the object does not abut a lip 41. When a defective part of an object such as a notch 25 on object 24 in figure 1 is adjacent pulley 23 or surface 18, or when an undersize object is in the chute 17, spring 35 pulls the pulley downwardly and as a result the object abuts and pivots about lip 41 Figure 3, (not shown) and falls from the apparatus. A catch 14 is provided to admit the objects one at a time. When an object is located in chute 17, catch 14 springs upwardly as shown in Figure 2 to prevent further objects from entering the chute 17. When the object leaves the chute at the end or is rejected, pulley 23 moves downwardly under the action of spring 35 and presses catch 14 down to admit a further object to chute 17. Arcuate test chute 17 may be replaced by a linear test chute.

Abstract: 1282174 Tobacco-smoke filter manufacture HAUNI-WERKE KORBER & CO KG 7 July 1969 [27 Sept 1968] 60536/71 Divided out of 1282173 Heading A2C A device for continuously wrapping a filler material, e.g. filter material 106, within a wrapper strip 114 provided with a band or hot melt adhesive (17) at one edge to form an overlap joint in a continuous wrapped rod 128, comprises a conveyer 107 for feeding the strip 114 and the material 106 superimposed on it in the axial direction through a rod forming unit 101 which folds the strip 114 around the material 106 and causes the adhesive-bearing edge to lap over the opposite edge of the wrapper strip 114, and means forming part of or immediately preceding said rod-forming unit 101 to ensure that the adhesive is in the active condition at the point where the adhesive-bearing edge of the strip 114 is laid down on to the opposite edge. The adhesive activity may be obtained by applying hot adhesive to the edge of the strip 114 immediately in advance of the said point, or a previously applied band of adhesive (17) may be activated either by heating the strip 114 immediately before the filter material 106 is placed on it or by heating the strip 114 within a guide member 103 forming part of the rodforming unit 101. The guide member 103 comprises upper and lower blocks each provided with a semicircular channel that cooperates with the other to form a guide for the rod 128, and each having bores 131a, 131b connected by manifold-like chambers 133a, 133b through which a heated liquid is circulated. Preferably a guide member (303B, Fig. 5 not shown), of similar construction to the member 103, and to which cooling air is supplied in place of the heated liquid, follows the rod forming unit 101 to positively cool the adhesive after the joint has been formed. The wrapper strip 114 may include additional bands of adhesive (18, 19) parallel to the band (17) on the edge of the strip, for connecting the strip 114 and the filter material 106.

Patent GB-661874-A (GB)
Abstract: 661,874. Transfer mechanism. AKTIEBOLAGET FACIT. April 22, 1948 [April 25, 1947], No. 11129/48. Class 106 (i). Transfer mechanism for a calculating machine comprises Geneva mechanism so arranged that a transfer from a numeral wheel to the numeral wheel of the next higher denomination begins as the lower numeral wheel starts to rotate in a positive direction from its zero position and is completed as the lower numeral wheel completes a full revolution, there being between these two points at least one pause during which the higher numeral wheel receives no transfer movement. The acceleration of the transfer mechanism at transfer is thus reduced, as compared with that occurring when transfer takes place suddenly, and yet is sufficiently high to produce a control impulse to stop operation of the associated differential actuator in division operations. Each numeral wheel 23 is geared to a gear-wheel 21 connected by co-operating Geneva wheels 26, 27 with a gearwheel 29 meshing with a gear-wheel 17. A planet wheel 18, carried by the wheel 17, meshes with a sun wheel 20 fast to the gearwheel 21 of the next higher denomination, The gear-ratios and Geneva pair are such that as a numeral wheel rotates through a quarter of a revolution from its zero position, the numeral wheel of the next higher denomination is rotated through a twentieth of a revolution, in which position it remains while the lower numeral wheel rotates through a further halfrevolution, and while the lower numeral wheel rotates through its final quarter-revolution; the higher numeral wheel rotates a further twentieth of a revolution to complete the transfer. In order to add to the transfer motion of a numeral wheel, a motion corresponding to that of the corresponding differential actuator, the latter is geared through a transmission wheel 12 to a toothed ring 13 mounted on a bearing 16 carried by the gear-wheel 17 and meshing also with the planet wheel 18, the parts being shown drawn apart axially. The gear-wheel 17 of the lowermost denomination is held against rotation by a pin 31. To control the differential actuators in division operations, the gear-wheels 21 have one or more elongated teeth 21a depending on the ratio of the gearing connecting them with the numeral wheels. Specification 661,873 is referred to.

Abstract: A mechanism is described by which the rudder bar and rudder of a kayak or similar craft can be turned to port or starboard by simply moving the left or right foot laterally along the footrest (10). The mechanism comprises a plate (26) pivotally mounted about a central pivot (22) which is supported by a bracket (16) attached to the footrest (10). Control lines (40, 42) are attached to opposite ends of the plate (26) which is symmetrically cut away along its rearwardly facing edge on opposite sides of the central pivot (22), to provide two concave depressions (44, 46). The ends (48, 50) of the plate (26) are not cut away in this manner and the plate is dimensioned so that these ends (48, 50) extend over and behind the footrest (10). By aligning the cutaway regions (44, 46) of the plate with the positions along the footrest normally occupied by the canoeist's feet, so the canoeist can bring his foot into contact with one or other of the two ends (48, 50) by simply moving his foot laterally outwards along the footrest. A spring (not shown) can be provided to return the plate or the rudder to the straight-ahead position. <IMAGE>

Title: Magnetic recording and reproducing apparatus
IPC: G11B23/00
Filed: 1978-09-19
Abstract: In the magnetic recording of a SECAM color television signal, the luminance signal is modulated in angle, while the frequency of the chrominance signal is converted to a predetermined lower frequency band through frequency division means solely or in combination with frequency conversion and recorded on a recording medium after having been superposed on the angular modulated luminance signal at a low band thereof. For reproduction, the luminance signal modulated in angle and the chrominance signal having frequency stepped down to the lower band are separated from the reproduced signal. The separated luminance signal is demodulated to obtain the reproduced luminance signal, while the separated chrominance signal is restored to the original frequency through frequency multiplier means solely or in combination with frequency conversion means and mixed to the reproduced luminance signal, thereby to produce the original SECAM system color television signal. By utilizing azimuth angle, high density recording such as guard-bandless recording can be attained. <IMAGE>
