Title: Improvements in or relating to finger or the like stalls
IPC: D05B91/04
Filed: 1930-07-17
Abstract: 359,457. Fingerstalls. McDOUGALL, C. B., 173, Riddiford Street, Wellington, New Zealand. July 17, 1930, No. 21663. Convention date, July 18, 1929. [Class 141.] A fingerstall is provided with an elastic insertion 4. In the form shown in the drawing, the fingerstall is made from two pieces 1, 2 of leather or other suitable material, the piece 2 being cut away as shown, the pieces being seamed together each side at 6.

Title: Improvements relating to machines for moulding dough or the like
IPC: A21C5/06
Filed: 1920-07-19
Abstract: 170,394. Lutze, A. July 19, 1920. Rotary-mould-table machines.-A machine for moulding dough &c. has moulds C' - - C', Fig. 5, open for their whole length along the periphery of a continuously rotating carrier B, Fig. 1, so as to be filled when passing under the feed-hopper A with material which is alternately compressed and discharged by pistons D' - D<3> opposite pairs of which are connected by levers F<1>, F<2>, guided by pins L moving in slots K and supported by the sphere T, which may be axially adjusted in the carrier B by the spindle H. The carrier is rotated by the shaft M, Fig. 2, which also actuates the pistons by oscillating about a fixed pivot, the arm T having at one end a member U, the curved surface of which presses against rollers on the pistons. A reciprocating movement is also given to the arm T by mounting it on slots x. The weight of the material in the moulds is determined by the pressure of the plate I, Fig. 5, which is adapted to allow surplus material to return to the hopper and is reciprocated by means of levers 3, 5, and rods 4 connected to the crank disc S<1> on the shaft M. Excess pressure is avoided by connecting the lever 5 to a rod 4 by a slotted guide and balancing the pressure on the plate I by means of an adjustable weight 12. In an alternative arrangement the material is also fed to the moulds by means of a worm. The pistons may also be actuated by rollers mounted on the circumference of a rotating disc.

Title: Projectile with a stabilizing element at its rear end
IPC: F42B10/30
Filed: 1966-05-17
Abstract: 1,141,534. Projectiles. SWEDEN FORSVARETS FABRIKSVERK, DIRECTOR GENERAL OF. 17 May, 1966 [14 June, 1965], No. 21936/66. Heading F3A. A projectile 3 is provided with a rearwardly directed stabilizing tube 1 having integrally formed flaps 5 which open out under residual gas pressure as the projectile is fired from a barrel. The flaps are defined by weakening means such as longitudinal slots 4 and by transverse weakening recesses or grooves 6 which initially have an outwardly diverging cross-section and which close up to limit the amount by which the flaps open out. In another form, four flaps (9), Figs. 4 and 5, are formed each with a radial fin (10, 12) across which a transverse weakening groove (13) extends. In a further embodiment the tube (15) is fixed to a rearwardly tapering projectile. This tube has a bottom wall (16) with a central aperture (17). Six flaps (21) are formed by slotting the bottom and side wall at (18, 20). A radial fin extends from each bottom section and forms a " V " with a fixed fin (23) on the side wall, the two fins abutting in open position of the rear fin. In a modification of this latter arrangement, a piston (29) slides on a fixed guide sleeve (28). Residual pressure finds its way behind the piston so that it forces open the flaps (27) along with the fins (39). The piston is looked in open position by a spring ring (33) entering a groove in the sleeve, thus positively locking the opened flaps in position. The transversely weakening recesses or grooves may be at a slight angle so that the opened fins assume a position to cause rotation of the projectile.

Title: Automatic exposure control arrangement for a camera
IPC: G01J1/42
Filed: 1966-05-18
Abstract: 1,149,623. Photo-electric camera exposure control. BELL & HOWELL CO. May 18, 1966 [May 20, 1965], No.22097/66. Heading G1A. [Also in Divisions G2, G4 and H3] An automatic camera exposure apparatus adjusts the diaphragm opening and shutter speed in dependence upon both the illumination of a scene and any motion in the scene. A photo-detector 30, preferably a photo-resistor, receives an image of the scene through a grating 32 so that as the object moves, in a direction transverse to a line between the object and camera, its image moves across the grating to give an alternating output from the photo-detector whose frequency is proportional to the speed of the object. This output signal is amplified and triggers a monostable multi-vibrator 36 to provide regularly shaped pulses and a D. C. signal is created at integrator 38 which is linearly proportional to frequency of the pulses. This D.C. signal by itself controls the shutter speed and together with a signal indicative of the illumination from photo-detector 24 provides a signal of from sum- - ming circuit 41 to control the diaphragm opening. Film speed variations are provided for by an adjustable plate in front of photo-detector 25. The grating 30 may have horizontal, diagonal or circular opaque and transparent lines or alternatively differing reflective areas. Instead of using a multi-vibrator 36 (also Fig. 6 not shown) a pulse clipping and shaping circuit can be used Fig. 11 (not shown).

Title: Method and means for copy-grinding
IPC: B24B17/02
Filed: 1951-09-24
Abstract: 700,136. Copy grinding ; trueing. FOUQUET, E. Sept. 24, 1951, No. 22352/51. Class 60 The grinding wheel 2A, Fig. 1, and the follower wheel 2B of an apparatus for copygrinding are of the same profile and diameter and have their diameters progressively reduced during the grinding of a work-piece P, the similarity of the profiles of the grinding wheel and follower roll being maintained. The reduction may be effected by a continuous trueing of both wheels by crushing rolls or by diamonds 25A, 25B, mounted on shafts 23A, 23B oscillated by a belt-driven crank 31, a connecting rod 29 and two forked members 28A, 28B. The latter two members are connected together by a ball-jointed rod 47 to ensure that the diamonds oscillate in unison. The shafts 23A, 23B are mounted in members 22A, 22B keyed to a shaft 19 and adapted to be tilted about the axis of this shaft to feed the diamonds to the wheels by a screw and nut feed device such as 36A, 39A operated by a pawl and ratchet from the reciprocation of the rod 47. The rate of feed may be adjusted by a tooth mask on the ratchet wheel. The grinding wheel and follower wheel are journalled in arms 1A, 1B, respectively and are rotated through belt drives 16A, 16B by electric motors 14A, 14B. Both arms are counterbalanced by a weight 13 and keyed to a shaft 3 mounted on one end of a support 5 oscillated about a fixed shaft 6 by a belt-driven crankshaft 8 and a connecting rod 12 to produce a transverse reciprocation of the grinding and follower wheels. The workpiece P and the pattern G are mounted between a common headstock 58 and centres 55, 59 adjustably secured to a table 48 reciprocated by a belt-driven rack and pinion. To enable a preliminary adjustment of the arms 1A, 1B to be effected, each screw 36A engages a nut 43A pivotally connected to an arm and is provided with a hand wheel 44A. The work piece and pattern may be rotated continuously or be indexed according to their shape. The follower wheel may be made from a material similar to that which serves as a binder for the abrasive of the grinding wheel. Fig. 3 shows a modification in which the follower wheel consists of a spool of tape which is gradually unwound by a ratchet-operated friction drive comprising two rollers 114, 115 one of which has a rubber-covered surface. The ratchet is operated in synchronism with the trueing device for the grinding wheel. A spring-loaded shoe 107 ensures that the tape remains tightly coiled. The tape may be magnetic and have a curved transverse profile to correspond with that of the grinding wheel.
