Title: Drive mechanism for a reciprocating member
IPC: B23D15/12
Filed: 1972-09-04
Abstract: 1367211 Punching INTERNATIONAL BUSINESS MACHINES CORP 4 Sept 1972 [28 Oct 1971] 40854/72 Heading B3W [Also in Division F2] A drive mechanism for a reciprocating member, e.g. the punch 100 of a web punching apparatus, comprises a pendulum-like oscillating drive member 111 coupled to the punch 100 by a cable 110 and mounted on a rotating support 104 and oscillatable under the control of centrifugal force resulting from the rotation of the support 104, and control means comprising a cam follower 114 coupled to the drive member 111 and controlled by a cam member 118 for initially moving the drive member 111 to one limit of its oscillating movement, so that subsequently the centrifugal force causes oscillation of the drive member 111 and corresponding reciprocation of the punch 100. The drive member 111 is an eccentrically weighted pulley, the weight 115 being so located that its mass centre of oscillation is furthest from the axis of rotation of the support 104 when the punch 100 is at the midpoint of its reciprocation stroke. The support 104 is screwed to a hollow shaft 101 for rotation. Cam follower 114 has a laterally projecting pin 116 that rides in a cam groove 117 in the inner radial face of the cam member 118 which is suitably anchored and disposed about the rotating shaft 101. Springs 103 nested in the support 104 act, through a plate 105, on the rear face 106 of punch 100 to maintain its V-shaped sides in slidable surface contact with corresponding mating surfaces of a die 107. The cutting edge 102 cuts V-shaped notches to remove triangular chips C from one edge of a web 108, the chips being removed through the hollow shaft 101 which is connected to a vacuum source. The mass and radius of oscillation of weighted pulley 111 are calculated to cause the pulley to oscillate at a fundamental natural frequency synchronized with the angular velocity of punch 100 as the punch will complete an integral number of harmonic reciprocations per revolution of shaft 101. Cam member 118 and cam follower 114 are provided merely to positively ensure that such synchronization will be maintained despite frictional drag. Driving force exerted by the pulley 111 on the punch 100 thus desirably increases as the angular velocity of the shaft 101 increases, whereas the load on the cam member 118 remains substantially negligible irrespective of angular velocity. This enables operation at very high rotational (and hence reciprocating) speeds that produce centrifugal forces significantly exceeding those possible with prior art arrangements.

Abstract: 920,200. Fuel elements. GENERAL ELECTRIC CO. Ltd. Dec. 11, 1959 [Dec. 18, 1958], No. 40903/58. Class 39 (4). A nuclear fuel element is associated with a thermocouple and is carried by a sleeve which has on its outside at least one pair of contacts connected to the thermocouple, the contacts being set apart on the sleeve and being adapted to co-operate with corresponding contacts on the wall of a channel in a nuclear reactor and one set of contacts being radially biased to engage the other set. Fig. 5 shows a fuel element, one of whose fins 31 is thickened to contain a thermocouple junction. The element is carried in a graphite sleeve 1. The leads from the thermocouple are sheathed in stainless steel and lead to spring contacts 9 and 10 mounted on ceramic discs 40. These contacts make contact with contact rings 12, 13 in the wall of the fuel channel. The spring contacts are 120 degrees apart and are axially spaced. A centring spring is also provided 120 degrees away from the contact springs. In other embodiments the contact springs may be closer together and may be replaced by spring-loaded buttons or gravity-loaded contacts. The biased contacts may be on the wall, not the sleeve. The sleeve and wall may have locating means, e.g. a tongue and groove, so that the wall contacts may be reduced in size from rings to patches. Specification 791,011 is referred to. Reference has been directed by the Comptroller to Specification 847,696.

Abstract: 1,180,799. Colour television tubes. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. 8 Sept., 1967 [13 Sept., 1966], No. 41186/67. Heading H1D In the manufacture of colour television screens of the type comprising strips of at least two different phosphors separated by opaque strips and including indexing strips overlying, for example, alternate opaque strips, the strips are formed with the aid of a set of matched masks produced from respective negatives formed from a common auxiliary mask by a radiation exposure process. Fig. 2, illustrates the production of a negative 95 on a curved glass screen 65 from the common auxiliary mask; this negative will correspond to the luminescent strips, so in the case of a three colour system two thirds of the transparent areas in the mask 2 are shielded by opaque areas in a supplementary mask 6, and two further negatives are made with the mask 6 displaced to expose other groups of strips for the other two colours. The planoparallel glass plate 4 is inclined at a small angle to displace the strips by a predetermined amount. When a negative is made corresponding to the opaque strips of the final screen (Fig. 1, not shown), the plate 4 is parallel to the auxiliary mask 2 and the mask 6 is omitted; when a negative is made for the index strips (Fig. 4, not shown) the plate 4 is parallel to mask 2 which is covered by a different supplementary mask which obscures alternate transparent areas. From the five negatives (three for coloured strips, one for intermediate opaque strips and one for index strips) corresponding masks are made by a further radiation exposure process (Fig. 5, not shown) which may include an optical system (151, Fig. 6, not shown). The radiation exposure processes may be either negative or positive. Fig. 9a illustrates the steps in an alternative method of producing the mask for the index strips. At a first exposure by a positive process the mask 208 is omitted and areas 210-214 on the negative 209 are exposed through the auxiliary mask 200. Mask 208 is then placed as shown and a planoparallel glass plate (not shown) is inserted to provide an optical shift such that areas 215-217 are exposed. From the negative 209 thus obtained the mask 218 is manufactured by a negative process.
