Title: Apparatus for Making Symbols, particularly for Coordinatographs
Inventor: FRENZEL FRITZ GUSTAV LEOPOLD
IPC: B43L13/00
Filed: 1966-11-15
Abstract: 1,166,494. Writing machines; selective printing. CARL ZEISS JENA, VEB. 15 Nov., 1966, No. 51082/66. Headings B6F and B6P. In a writing machine, a marker 3 provided with an exchangeable stylus 6, is suspended in ball-joint fashion in a bearing 2, and is capable of axial movement against the force of a compression spring 7. The end adjacent the stylus 6 is received in the aperture of a ring 41, which ring is moved in the and y co-ordinate directions according to the profiles of a series of cams 19, 21 carried by a rotatable drum 18. In operation, an electric motor 61 drives, in step-wise fashion via a Maltese cross 50 (Fig. 3) and a gear-wheel 46, a disc 16 to which is attached the drum 18. In this manner a certain series of cams is selected. Thereupon a motor 44 rotates a cam follower 12 about the axis X-X, so that a wheel 14 rolls on a cam surface 15 of a ring 4 mounted on the disc 16. The drum 18 is therefore lowered, so that the ring 41 is moved into its starting position by two levers 29 and (30, Fig. 2) following the profiles of the selected cams 19 and 21. At the same time a bell-crank lever 26 is pivoted about 25 in conformity with the cam 20, so that the marker 3 is moved axially downwards, to bring the stylus 6 into contact with the drawing surface. As the drum 18 moves upwards under the action of a compression spring 22, the stylus describes a curve corresponding to the profiles of the selected cams, before the marker 3 is returned to its starting position by lever 26. Energizing an electromagnet 74 causes an armature 73 to rotate the lever 26, so that the marker 3 is lowered to the drawing surface for point marking.

Title: Apparatus for article theft detection
IPC: G08B13/24
Filed: 1971-11-03
Abstract: 1329194 Inductive signalling KNOGO CORP 3 Nov 1971 [2 Dec 1970] 51113/71 Heading H4U [Also in Division G4] Theft of articles is indicated at 20 by the effect of a timed circuit attached to each article upon a signal supplied to an antenna 10 near an exit from the protected area, and erroneous operation is inhibited at 28 by a duplicate system 2 having another antenna 21. The signal generator 11 energizing both antennae has its frequency swept by 13, 14, 12 and a drop in signal amplitude at 16 due to presence of a timed circuit near the antenna 10 is detected as a pulse at 18 to operate a relay 19 and alarm 20 which may be audio, visual, or an automatic door locking arrangement. Spurious signals which may energize the pulse detecting system 15-18 of the main antenna 10 also energize the duplicate pulse detecting system 2 (22-25) controlled by the second antenna, and operate a relay 27 to disable the alarm 20. The antenna 21 is placed far enough from 10 however not to be affected by a stolen article. The same oscillator 11 as shown or a separate one may be used to energize the duplicate system. A refinement of this arrangement (Fig. 3, not shown) has both main and second antennae 10, 21 arranged to detect a stolen article at one exit, and both antennae 10, 21 of a second similar pair of detecting systems (39, 43) arranged to detect a stolen article at a second adjacent exit, but with the duplicate detecting systems 42 (43) arranged to disable the alarms of the non-associated main detectors (39) 36. This prevents the system at one exit responding to a stolen article at the other. In a differently arranged embodiment (Fig. 2, not shown) the main antenna and associated pulse detector (3) is associated with one exit and an identical arrangement (4) constituting the duplicate system with an adjacent exit. The pulse amplitudes produced (at 18) are compared in discriminators (34, 35) which enable appropriate gates (19) so that the antenna whose detector produces the largest pulse is allowed to operate its alarm. This again prevents stolen articles in one exit operating the alarm in an adjacent exit.

Filed: 1976-12-08
Abstract: 1521395 Double acting jack P COLLY 8 Dec 1976 [24 Dec 1975] 51220/76 Heading F1D A double acting jack, Fig. 1, comprises a hollow piston 3 reciprocable in a cylinder 2 the stroke of the piston being limited by contact between a stop ring 17 and a nut 15 which is prevented from rotating by a projection 16 which engages an opening 20 in the inside wall of the piston 3, a lead screw 14 which is rotatable by means of a worm 24 and gear 23 to adjust the position of the nut 15 which screw threadingly engages the lead screw, an endplate 4 and seals 6, 8, 30. Pressurized fluid supplied by line 29 to channel 31 passes into a channel 35 Fig. 2, formed in the lead screw, via annular openings 32, 33 formed in the lead screw 14 and end-plate 4 respectively, and then via an opening 36 cut-out 37 and channels 11a to the working chamber 25 of the jack causing displacement of the piston. As the piston nears the end of its stroke the stop ring 17 contacts the nut 15 causing axial movement of the lead screw so that a shoulder 26 of the lead screw abuts a ring 28 thereby preventing further flow of fluid to the chamber 25. In this way the force exerted on the nut 15 is limited. The piston may be returned by admitting fluid through a line 43 to an annular chamber 41 the fluid in the chamber 25 being expelled via channel 38, check valve 39 and line 40.

The predetermined number is preferably five or four. The first phase difference (which is a number between 00 and 99) is entered from 23 into the two stages 1 and 2 of a BCD counter. The lowest significant figure is transmitted as a pulse train to store 12 when energized by line L01 and the next figure from counter 1 to similarly energized store 11. The contents of all stores 8-12 are decoded at 13-17 and displayed on seven segment indicators 18-22. Logic circuitry 3 then sets into the counters the value 5 minus the value in store 11. The next phase difference is added to the value in the counter and the figure in counter 1 is then transferred to store 10 when energized by line L 1 . The counter is again set using the most significant figure of the partial result which, this time, is in store 10. The succeeding phase differences are similarly processed, there being as many stores and seven segment readouts as desired. This system allows for phase errors of up to 5%. A meter 24 connected to digital to analogue converter 25 indicates the number in counter 2 which equals 5 plus the percentage error and may be calbrated to read this error directly.
