Title: Methods of and devices for braking and indexing the spindle of a machine tool rotating at high speed
IPC: B23Q15/26
Filed: 1973-09-05
Abstract: 1439665 Automatic braking and indexing REGIE NATIONALE DES USINES RENAULT 5 Sept 1973 [26 Sept 1972 3 Aug 1973] 41731/73 heading G3N In the braking and indexing of a rotating spindle, braking is initiated at a predetermined angular position of the spindle, and takes place, at least in part, according to the law #=#2K(# 1 -#), where K is a constant, # = current spindle angle corresponding to angular speed #, # 1   = constant, i.e. angle at which # = 0, see Fig. 1 (not shown). The law is equivalent to constant deceleration see (1) (Fig. 1). As shown braking of mechanically coupled spindles 10, 11 is initiated when unit 27 receives simultaneously a brake order from control 28, and a shaped index pulse from pick-up 24 detecting mark 22 on disc 20 mechanically connected to the spindles, to enable counter 29 to be counted down in dependence on spindle angle by shaped pulses derived from pick-up 23 detecting marks 21 on the disc 20. The count is converted to analogue form in unit 31 and its square root, extracted in unit 32, passes via variable gain amplifier 33 to provide a time variable speed reference signal to comparator 35 receiving an actual speed signal from tachymetric current generator 19 via feedback adjuster 38. The comparator error signal output, via amplifier 36 controls system 37 itself controlling an electromagnetic brake 14 coupled to the spindles, see curve (I), Fig. 4 (not shown). Detection of the passage of the speed reference through a threshold, by unit 39 changes switch blade 34a to position II, function generator 40 providing a new speed reference also representing constant shaft deceleration (II, Fig. 4). A locking circuit 41 detects when the count of counter 29 has reduced to a predetermined value{eg. zero} and provides to adder 41a a control signal leading to forceful brake application (III, Fig. 4,) to stop the spindles in the required angular position. During machining operation the spindles are driven by motor 16, possibly via clutch 15 which may be used to decouple the spindles and motor 16, instead of de-energizing the latter, during braking. Spindle 10 supports a workpiece 17, there being a reference piece or master 18 on spindle 11, the system being used for sequential machining. In the embodiment of Fig. 2 (not shown), the spindle B is driven from an indexed initial position to rest according to a parabolic #-# law, i.e. constant deceleration.

Filed: 1959-12-09
Abstract: 936,964. Photographic cameras. VOIGTLANDER A.G. Dec. 9, 1959 [Dec. 9, 1958], No. 41910/59. Class 98 (1). In a photographic camera having a viewfinder including a prism in its ray path with the camera cap, the prism carries additional optical means whereby an image of an external adjustment scale and reference mark connected to the corresponding camera setting member is formed in or adjacent the field of the viewfinder, so that an image of the scale and mark and an image of the scene may be observed simultaneously. The camera may be a twin lens or a single lens reflex camera or a kinematograph camera. As shown for a reflex camera, a pentagonal roof prism 5 erects and laterally inverts the image seen in the eyepiece 6 of the image formed on the plane focusing screen surface of the field lens 4. A prism 26 cemented on a non- silvered face 27 of the roof prism 5 directs an image of the speed and aperture scales 8, 9 on the shutter-diaphragm unit into the viewfinder eyepiece. A shaft 25 extending from the shutterdiaphragm unit and setting shutter and diaphragm to combinations representing particular light values is connected by gearing 23, 24 to a light value setting knob 22 coaxial with the rollfilm rewinding knob 14 (Fig. 1, not shown) and having a cam 21 controlling a follow-up member 18 for the pointer 17 of a photo-electric exposure meter, both the follow-up member and pointer being disposed close to the bottom face of the prism 5. The view seen by an eye at 7 is shown in Fig. 9. By arranging the supplementary prism on the lower scene finder reflecting surface 35 of the prism 5 the scales appear within the limits of the finder field, while by causing the beam forming the scale image to be reflected at the junction between surfaces 27, 35 the scales straddle the finder field boundary. A negative lens may be attached to the inlet face of the supplementary prism 26 so as to allow an image of the focusing scale 1 and depth of focus indicators 11 to be formed in the eyepiece 6. Alternatively by providing vertical extensions of the rings bearing the scales 1, 8, 9 close to the base of the face 35 of the prism 5 to which is attached a positive lens with or without an intervening wedge prism the scales may be visible at the bottom of the finder field.

Title: Digital control system for positioning shafts
IPC: H03M1/00
Filed: 1959-12-14
Abstract: 883,737. Programmed electric control systems. SOC. D'ELECTRONIQUE ET D'AUTOMATISME S.A. Dec. 14, 1959 [Dec. 19, 1958], No. 42389/59. Class 38 (6). The angular position of a shaft is controlled from a binary coded record by first positioning an auxiliary shaft which carries a coding disc until the outputs of the disc and the record coincide; and then rotating the main shaft until it coincides with the auxiliary shaft. The desired sequence of shaft positions is recorded on a punched tape 12, as follows. In the first row of 5 bits, a signal in the 5th column indicates the direction of rotation, the remaining 4 columns remaining blank. The second row contains the " tens " of a decimal number using a 4-bit binary code. The third row similarly contains the " units." The arrangement then repeats as desired. The shaft thus has 100 possible angular settings. The " excess 3 " code is used, i.e. zero is expressed as conventional binary 3, one as conventional 4, &c. The direction of rotation signal amplified at 16 is stored at 17 and also controls a reversing relay 29 controlling a motor 4 which drives the auxiliary shaft 3. Auxiliary shaft 3 carries a coding disc 9, which is rotatable past eight photo-electric readers 11. The disc, Fig. 2 (not shown), is divided in 100 sectors numbered in the reflected binary code. The four inner code rings defining the " tens " and the outer four rings the " units." The outputs of the " tens " readers are passed by gates 22 to a coincidence comparator 20 for comparison with the " tens " output of the tape reader. This output is first converted from the excess 3 binary code to the reflected binary code at 19. Any output from comparator 20 causes motor 4 to rotate the disc 9 into coincidence. The tape 12 is then moved and the " units " read, and gates 23 are closed so that the " units " from the disc are read, and the motor 4 is again energized until the disc 9 is in coincidence. The tape 12 is again moved on and the next direction of rotation sign read and stored. The original direction of rotation sign moves on to an auxiliary store 33 to control a reversing relay 35 for the motor 2 driving the main shaft 1. A gate 38 is now rendered conductive and the motor 2 drives shaft 1 until light from a source 7 falls on a photo-diode 8 through an index slot in a further disc 5 also on shaft 3 so that shafts 1 and 3 are in coincidence. The diode 8 then renders gate 38 non-conducting and also applies a transfer pulse to a gate 18 so that the tape 12 steps forward to the next "tens " instruction and the cycle repeats.
