Title: Stripping apparatus
IPC: B26D7/18
Filed: 1974-09-25
Abstract: 1463527 Stripping waste from cut blanks ROCKWELL INTERNATIONAL CORP 25 Sept 1974 [12 Nov 1973] 41627/74 Heading B4B  A stripping apparatus for separating waste pieces W from pro-cut sheet material 12, e.g. carton blanks, comprises a rotatable cylinder 13 provided with stripper pins 18 which co-operate with a roller 10 to impale the waste pieces as the material passes between the roller and cylinder and a combing drum 30 adapted to rotate eccentrically about the cylinder so as to remove the waste pieces from the stripper pins. The stripper pins are each provided with a point 38 and a pair of flexible legs (42, 43) Fig. 2 (not shown) formed with shoulders (46, 47). The legs are pressed through a hole 56 formed in the cylinder so that the legs spring apart and lock the shoulders on the inside surface of the cylinder. The drum 30 is provided with aligned clearance slots which allow the pins to move relatively thereto during operation as shown in Fig. 1. The cylinder 13 is mounted on discs 74, 97, the disc 74 being connected to a drive shaft 64 and the disc 97 to a stub shaft 94. The shaft 64 is rotatably mounted in a sleeve 67 secured to a side frame 61 and the stub shaft, rotatable in a sleeve 92 which is supported by an axially movable non-rotatable arbor 83. The combing drum 30 is mounted, at respective ends, on housings 76, 101 which are rotatable on the respective sleeves 67, 92. The combing drum and pin cylinder are easily removable by withdrawing the arbor from the sleeve 92 via a manually-operated rack-and-pinion drive 91, then removing the housing 101 and disc 97 so that both the cylinder and drum may be axially removed from the disc 74 and housing 76. To facilitate the separation of the waste pieces W from the material, spaced wires 22, Fig. 1, are provided.

A transformer, which may be an auto transformer, has a tertiary winding TW whose effective output voltage U3 is maintained constant by the auxiliary transformer ZTr when tap changer RS regulates the output from either U1 or U2, the other being a constant input voltage. Formulae are given for the transformation ratio of ZTr for the cases where U1 is greater than U2 and less than U2, and it is shown that U3 is then independent of the tap changer position. The voltage of further windings such as TW may be maintained constant by additional secondaries on ZTr (Fig. 3, not shown). The main transformer may have independent primary and secondary (Fig. 4, not shown). For three-phase embodiments various ways of adding the auxiliary voltages to the tertiary voltages are described (Figs. 5, 6, 7, 8, not shown).

[Also in Group XXXVIII] The vibrations at different parts of a vehicle are measured with a fixed counter-electrode, to modulate each of its own carrier frequency, and the signals are fed to a tape recorder, being subsequently reproduced and separated. As shown, an earthed member 14 whose vibrations are to be measured, forms one electrode of a capacitor, the other electrode 15 being surrounded by a guard plate 16. The capacitor 14, 15 is connected in the negative feedback path of a high-gain amplifier 18 fed from a constant current generator 20, whereby the current through capacitor 14, 15 is also constant, and the voltage output from amplifier 18 is proportional to the spacing between electrodes 14, 15. This amplitude-modulated signal voltage is combined at 31 with similar signals of different carrier frequencies derived from separate transducers 11, 12, and fed to a taperecording head 27. The tape 24 has prerecorded on it the three carrier frequencies combined on one track, which are read off at 25 and separated into the individual frequencies by filters 28, 29, 30, each controlling its constant current generator 20. Specifications 863,397 and 912,041 are referred to.

In a mounting jig for the annular cores 20 of a magnetic storage matrix in which the cores are retained by suction in locating apertures in readiness for wiring, the jig is formed of a plurality of metal plates 11, 12, 13 each having a pattern of apertures formed by a photoetching process using the same or identical templates, the lowest plate 13 through which suction is applied having its apertures 21 reduced in size by an electrodeposited metal coating 14. The method of construction enables the smaller and larger apertures to be precisely aligned. Copper plates are used which are coated with a layer of a polymer to be hardened by means of actinic rays. A transparency having the desired pattern of apertures is used to selectively harden the layer, the non- exposed places having the lacquer removed by washing. The uncovered copper on both sides is then perforated by etching to give a pattern of locating slots. The plate 13 is then formed by nickel and copper electroplating in turn. The intermediate plate may be coated on both sides before assembly with electrodeposited solder, the assembled plates being soldered together by heating.

Abstract: 1496760 Optical guidance LILLEY-WADDINGTON Ltd 17 Dec 1974 [17 Sept 1973] 43576/73 Heading H4D In the construction of a tunnel 22, Figs. 1, 2, the tunnelling shield 20, advanced by means of hydraulic rams 1-12 is guided by means of a laser beam 30 and a photoelectric target 32 mounted on the shield, the target incorporating a reference point such as to give output signals indicative of the deviation of the incident beam from the point and the shield from its correct position, which signals may be fed to an indicator or used to activate one or more of the rams. The target 32 is mounted on means enabling the correction of any roll of the shield. Fig. 4 shows the target in detail wherein the four square selenium cells or silicon photo-diodes are arranged with their edges abutting and at 45 degrees to the vertical to constitute top (T), bottom (B), left (L) and right (R) detector elements. An alternative arrangement of the detector elements is shown in Fig. 8. The detectors are mounted for horizontal and vertical movement relative to the target plate 36 and shield by horizontal-cursor 38 moving over the plate, and vertical cursor 12 moving along the horizontal cursor. The laser beam may impinge at 52. A transparent screen 60, Fig. 7, carrying radial opaque lines may be placed over the detectors to ensure that as the spot 52 moves further away from the centre of the detector a larger signal is given by the element. The signals from the elements are fed to the valves controlling the rams and also to a C.R.T. display, Fig. 5, wherein symbols 1-12 arranged around the C.R.T. screen represent the rams and the numbered concentric diamonds on the screen represent various distances of the spot 52 from the detector centre. The bright-up spot 54 corresponding to spot 52 indicates that rams 7 and 8 should be actuated to correct the displacement.
