Abstract: 1426887 Connecting electrical components to adhesive tape ROWE INTERNATIONAL Inc 5 Oct 1973 [30 Oct 1972] 46724/73 Headings B8C and B8P Apparatus for forming a string of different components having bodies and leads comprises means 78 (80) for receiving the leads of the components and advancing the components to a centring station where the bodies are centred, and means 162 adjacent the station for percussively driving each lead into engagement with an adhesive tape 18. The components are fed manually from boxes (34) of different components, mounted on a rotatable table (30) between guides 72, 74, 76 into grooves 100 in rotatable wheels forming the means 78 (80). A shaft 166 oscillated by a cam 182 carries a rod 176 which engages a crank (150) or 152 to cause flexible fingers (142) 144 to move inwardly to centre each component. The shaft 166 also carries hammers 162 (164) which push the leads of each component into grooves 110 in wheels 102 (104) and into engagement with a pair of spaced upper tapes 18 (22). Spaced, grooved wheels 122 press lower tapes into engagement with the upper tapes. A control system permits a single or double spacing of the components. Each box (34) has a patch of hook-like elements and a patch of loops on its base to enable the box to be correctly positioned on the table which has complementary patches.

Abstract: 1,121,128. Measuring electrical conductivity. ELECTRONIC SWITCHGEAR (LONDON) Ltd. Nov. 16, 1965 [Nov. 17, 1964], No. 46827/64. Heading G1N. In a liquid conductivity cell, one of its electrodes is arranged so that its surface area exposed to the liquid in the cell can be varied. This stainless steel electrode 22, Figs. 1 and 3 (latter not shown), is slidably housed in an electrically insulating sheath of PTFE 17, Fig. 1, or of moulded silica loaded epoxy resin 16a, Fig. 3 (not shown). A rod 20 secured within the sheath, has one end 21 screw-threaded, to co-operate with a screwthreaded bore through the electrode 22. After the adjustment has been made, by rotating the electrode along the rod 20, it may be locked into position by inserting a grub screw 23 into the exposed end of its bore. The sheath itself is screwed into an outer casing 10 of metal, e. g. stainless steel, which is screw-threaded at 11 to fit into an aperture in a fluid flow pipe or fluid container 12. The second electrode is constituted by a stainless steel, open-ended cylinder 13, with fluid flow apertures 14. In a modification, Fig. 2 (not shown), the rod 20 and electrode 22 are replaced by an electrode (30) extending through a bore in a composite sheath comprising two parts (28), (32), separated by a collar of PTFE. The electrode is adjusted by screwing it through a nut (35), and thereafter is locked into position by compressing the collar (31) by tightening a gland nut (25).

Title: Roller baling press
IPC: A01F15/07
Filed: 1977-11-11
Abstract: The rolled-bale press is equipped with a pick-up device (6) and with a following approximately cylindrical press space (3), on the circumference of which are arranged a plurality of driven conveying rollers (2) lined up in a row. Between the conveying rollers (2), the pick-up device (6) is followed by a drawing-in gap (5). To avoid chain drives involving a high outlay and requiring maintenance, the drive of the conveying rollers (2) is carried out via a central driving wheel (7) which is arranged coaxially relative to the centre axis (4) of the press space (3) and the circumference of which is drive-connected to corresponding driving wheels (10) of the conveying rollers (2). The central driving wheel (7) forms a side wall of the press space (3), as a result of which the braking of the crop during winding is avoided and a low drive power is therefore also needed. <IMAGE>

Abstract: 1,151,959. Printing-apparatus. ADDRESSOGRAPH-MULTIGRAPH CORP. 24 Oct., 1967 [25 Oct., 1966], No. 48375/67. Heading B6C. A cylinder printing machine suitable for printing from an embossed plate P comprises a bed 26 for holding a forme F to be printed, a carriage 28 supporting a roller platen 52 and adapted to be moved across the bed along a track 14 to perform the printing operation, and means 40 movable towards the bed to clamp the forme thereagainst and away from the bed to release the forme, the means 40 being moved as a result of the motion of the carriage, whereby the said means is in a clamping position as the roller 52 moves over the forme to effect printing. As the roller 52 is moved away from its home position, an actuating roller 60 rides along a cam slot (84), Fig. 3 (not shown), in the device 40 causing the device to pivot so that its plate 80 is lowered into engagement with the forme. The plate 80 is provided with an opening 82 large enough to expose the data on the plate to be printed. At about the same time a plate 44 engages a portion 64 of a trip member 62 causing a member 42 to be rotated and the roller 52 to be lowered to a printing level. The roller is maintained at this level by an overcentre spring 58 until an ear 47 on the carriage strikes a pin 66. The slot (84) is designed to allow an operator to position the forme accurately before secure clamping and printing occur. The forme is securely clamped until the roller is returned to its home position.

Title: Sound production device

Abstract: 1,118,407. Diaphragm vibrators. MATTEL Inc. 15 Nov., 1965 [12 April, 1965], No. 48387/65. Heading G5J. A sound production device comprises a resonator adapted to emit sounds when subjected to repetitive shock excitation by a rotary member and an arrangement whereby there sonator is selectively able to simulate either sounds similar to those produced by an I.C. engine or sounds similar to those of a siren, a manually reciprocable crank and a transmission system operative between the rotary member and the crank to convert the reciprocatory motion of the crank into continuous rotation of the rotary member. The device is for use in particular in toy vehicles. As shown, a cylindrical member 128 of a tone arm 110 has a ball 132 at one end which engages in a series of radial grooves cut in one side of a geared rotatable wheel 16 and the other end communicates with a piston 102 of a resonator 10. The piston is biased towards the tone arm by a spring 112 attached to a pin 116 extending from a spider 120 of the resonator. By operating a handle 144 the ball 132 may be moved to different radial positions on the wheel 16 corresponding to different series of grooves to alter the pitch of the sounds produced. By stroking a hand-operated crank 30 the wheel 16 is driven through a cluster gear arrangement that only co-operates with the small gear on the wheel 16 mounted on the opposite side to the grooves when the crank is operated in one direction. The peripheral gearing 80 on the wheel 16 engages a small gear wheel 72 of a friction clutch 70 having a series of flexible arms 74 that ride over projections 76 on the inside of a flywheel 24 until one of the arms engages a projection and the flywheel rotates with the friction clutch. Thus when the stroking of the crank has ceased the energy stored in the flywheel is sufficient to operate the device for some time afterwards. The specification gives specific examples and a general indication of the criteria to consider when selecting a material suitable for forming the resonator to give the desired sounds.
