Title: Improvements relating to guides for cables and the like
IPC: B66B7/06
Filed: 1943-02-19
Abstract: 566,292. Fairleads. TINNERMAN PRODUCTS, Inc. Feb. 19, 1943, No. 2785. Convention date, June 26, 1942. [Class 78 (v)] [Also in Group XXXIII] A fairlead for a cable through a partition, for example, in an aeroplane, comprises a tubular guide block with a spherical exterior mounted on a clamp engaging the spherical surface and supported on the partition and in a modified form, the guide hole in the block can be adjusted laterally so as to avoid the necessity for accuracy in the original positioning of the clamp on the partition. The guide block 16 is in two parts with semi-cylindrical central recess 12 and dowel locating means 13, 14 and fits between circular openings 31, 21 in two plates 30, 20 the latter having struck-out tongues 23 with flanges 24 to engage the partition A when the whole is attached by screws c which pass through holes a<1>, 25 and engage nut-like edges 33 struck up to form threaded edges in holes 32 in the farther plate 30. In a cheaper construction, the partition D, Fig. 4, may form one cheek of the clamp. When an adjustable guide hole is necessary the fairlead is formed in three parts, a central double conical barrel 40 with guide passage 43 eccentric of U-section leading to the periphery, retained between two ring members 50 of identical form with interlocking gate and tongue 52, 57, the outer surface of the assembled members being spherical for mounting as in the preceding form in Fig. 1. A notch 45 in the barrel 40 can be used to adjust it with a screw-driver to suit the partition opening. This three-part fairlead can also be mounted, as shown in Fig. 9, with the partition D forming one cheek of the clamp.

Title: Improvements in or relating to pushers for feeding bar stock in screw and like machines
IPC: B23B13/12
Filed: 1940-02-19
Abstract: 536,546. Turning. MARTIN, S. B. Feb. 15, 1940, No. 2931. Convention date, March 2, 1939. [Class 83 (iii)] A reciprocating feed member 1 for feeding bar stock 4 in a screw machine &c. has means for releasing the grip by manual reverse rotation of the stock bar so that the bar may be removed rearwardly from the machine if necessary. The forward end of the feed member is threaded to receive a nut 3. The bar is gripped by a segmental bushing 5, contracted on to the bar by a split resilient band 8 of spring steel the band having a tapered outer face 10 coacting with an internal taper on the member 1 so that the bar is gripped and fed on forward movement of the member 1 and released on the rearward movement. The bushing 5 has offset projections 12 coacting with similar recesses 15 in the nut 3. To release the bar it is first pushed forward and then turned reversely to the spindle rotation, thereby interlocking the projections 12 and recesses 15 and disengaging the taper surface of the spring band from its seating. The bar may then be withdrawn to the left by a force sufficient to overcome the grip of the bushing on the bar. In a modification the taper 11 may be provided on a hardened insert in the member 1. The positions of the projections 12 and recesses 15 may also be interchanged. In another modification, Fig. 6, the taper surface 23 is provided on a member 17 which is threaded at 18 and is screwed past coacting threads 20 inside the member 1 so that the bar 4 may rotate with the members 5 and 17 within the feed member 1.

Title: Scanning apparatus
IPC: G03F7/20
Filed: 1976-01-27
Abstract: 1532301 Scanning apparatus G WESTERBERG 27 Jan 1976 [13 Feb 1975] 3119/76 Heading G2A [Also in Division H4] In a raster scanning apparatus, for use in making masks for manufacturing micro circuits, the fast component of scan is provided by an oscillating slide which directs a radiation beam on to a radiation sensitive medium carried by a further, slow moving slide. As described, a light-sensitive medium 14 is stepwise moved perpendicular to the plane of the drawing whilst slide 12, pneumatically mounted and bearing optical reflecting and focusing means 13, oscillates in an orthogonal direction under the influence of two helical springs so that light from laser 31, modulated at 31a scans across medium 14. The amplitude of oscillation of slide 12 may be controlled by attaching one spring either at its end or at some point of its length to a "loud-speaker coil" i.e. a coil carrying A.C. in a circular magnetic field. Alternatively the driving coil may be directly connected to the slide 12. By varying the amplitude of vibration of the coil, the amplitude of slide 12 can be varied to a greater degree. The A.C. generator 4 is controlled by a feedback signal obtained from a Michelson interferometer Fig. 4 (not shown) coupled with a photo-detector and an r.c. circuit which signal is dependent on the speed of the slide 12. The driving device (moving coil described above) may alternatively be electromagnetic, Piezo-electric or pneumatic and the interferometer may be replaced by an optical grating, or by a magnetic device. As a further alternative the amplitude of vibration of the slide 12 may be detected and a control signal produced by an inductive capacitive, pneumatic or optical transducer. Furthermore the control signal could be used to vary the frequency of generator 4 so that it approaches or recedes from the resonant frequency of the mechanical system.

Abstract: 266,527. Hollingdale, C. P. Feb. 9, 1926. Periodic-counter speed indicators.-The average speed of a vehicle &c. over successive periods is registered by means of a number of pointers coupled in turn to the prime mover under a timing-control held stationary when the prime mover is stopped. A central shaft 6 driven from the vehicle has a gear wheel 8 adapted to drive a number of pointer spindles 5 one at a time through pinions 9 fixed to spindles 10 urged upwardly by springs 11. The upper ends of the spindles 10 are engaged successively by a cam surface on a disc 13, rotated by clockwork in the space 15, so as to couple the pointer spindles 5 to the drive. When the coupling has ceased each spindle is retained against spring-return by a ratchet-wheel 17 and pawl 18. Eventually a cam on the disc 13 rocks the pawl to free the spindle so that it returns to zero preparatory to its next coupling period. A masking plate 22 is connected with the cam disc 13 in order to cover those pointers which are undergoing the zeroizing and registering operation. To stop the clockwork while the vehicle is stationary, a ratchet drive 24 is inserted between the shaft 6 and the disc 13 to permit the latter to revolve only while the vehicle is travelling.
