Filed: 1971-06-08
Abstract: 1320057 Fuel injection valve DAIMLERBENZ AG 8 June 1971 [10 June 1970] 19478/71 Heading F1B I.C. engine fuel injection valve comprises a body 3 having a bore in which slides a stepped needle 4, the lower part 7 of the needle cooperating with a valve seat 5 to close a passage 18 leading to two injection holes 19 and 20, and the upper part 6 of the needle being guided by the bore. Fuel is supplied through a pipe 2 to the annular space 8 surrounding the part 7 and also, through a constriction to a chamber 12, the lower surface of which is formed by the head of the needle. The upper side of the chamber is closed by a valve 13 attached to the bottom end of a ceramic column 14 which exhibits a Piezo-electric effect. A pulse transformer 16 surrounds the column and has a primary winding to which low-voltage rectangular pulses are applied. The induced high-voltage pulse in the secondary causes contraction of the column and unseats the valve 13 so that fluid can escape from the chamber 12 to a drain pipe 21. Due to the constriction between the chamber 12 and the feed pipe 2, the pressure in chamber 12 drops and the pressure of the fuel in an enlargement 9 of the annular space 8, acts on the shoulder between the two diameters of the needle and raises the needle off its seat 5. Fuel injection ceases when the secondary voltage reverses. The column 14 consists of a number of superimposed cylinders connected in parallel to helical conductors 15. The valve 13 may be replaced by a piston.

Title: Improvements in photoelectric control
IPC: B26D5/34
Filed: 1944-10-12
Abstract: 589,300. Thermionic valve circuits; photo-electric control of strip-feeding mechanism. TRIGGS, W. W. (Photoswitch, Inc.). Oct. 12, 1944, No. 19699. [Classes 40 (iii) and 40 (v)] In an electric control system comprising a pair of reciprocally coupled valves with a relay in the output of one, the common circuit of the two valves supplies a constant voltage to a controlling network. One valve is normally conductive and when a control impulse is applied to its grid conductivity is shifted to the other valve to operate the relay. The first valve is rendered conductive again either by the operation of a switch or under the control of a timedelay circuit. Fig. 1 shows a cutting machine operative under control of marks m on the material. Section I of the tube T2 is conductive so that contact S1 is in the position shown and relay M2 is energized, holding the cutter 20. When a mark passes the amount of light reflected to the photocell T4 is decreased so that a positive impulse is applied to grid g of valve T1, thus rendering Section I of the Tube T2 less conductive. Consequent upon this, Section II becomes conductive to trigger Section I. When relay M1 is energized, the cutter is operated through M3. The operation of the cutter operates switch S2 so removing potential from the cathode of Section II and rendering this Section non-conductive and restoring conductivity to Section I. Fig. 2 shows a modification responsive to an increase in the illumination, photocell T4 and resistance R8 being interchanged. In this arrangement restoration, instead of being effected by a switch, is effected by a condenser C8, being discharged to a potential where Section I conducts.

Title: Photographic camera
IPC: G03B7/12
Filed: 1962-05-22
Abstract: 975,117. Photographic camera shutter means. AGFA A. G. May 22, 1962 [May 25, 1961], No. 19707/62. Heading G2A. A photographic camera having for optional use a delayed action mechanism for shutter release, an automatic exposure regulating device and means for manual exposure setting, includes a change-over device for rendering the automatic exposure regulating device inoperative to allow manual setting, the said change-over device being provided with a control cam for engagement with the delayed action mechanism in a corresponding control position in order to bring the same into operation. The camera shown comprises a shutter housing 1 a shutter speed control ring 3 with a cam slot 4 engaging a pin 5 for varying the shutter speed and a slot 6 for bulb setting control. Ring 3 is linked to exploring means 12 for an exposure meter galvanometer pointer 13. Ring 3 also has a slot 76 the end 18 can engage pin 19 on a diaphragm setting ring 20. Ring 20 can be rotated manually by means of ring 27. A change-over ring 30 is provided with cams 38, 42, 52 for co-operating with lever 39, pin 43 on a delay mechanism plate 46 and pin 57 on a release lever 54 respectively. The camera is operated by a rod 60. Ring 30 may be set by means of marks 31-35 and index 36 for automatic exposure with and without delayed action, flash with and without delayed action and bulb settings respectively. For taking an exposure with automatic exposure setting without delayed action, pin 57 is set in the arcuate part of slot 58 and when rod 60 is moved in direction b it is latched by pawl 63, end 68 moves away from pin 69 so ring 50 is rotated by spring 70, ring 3 is rotated by spring 15 until means 12 abuts pointer 13 thereby automatically setting the shutter speed and diaphragm aperture, pin 72 on ring 50 engages lug 73 and operates the shutter, pin 72 then engages and rotates latch 63 which frees rod 60 which moves under spring 61 to its initial position simultaneously moving the other parts to their initial position. For automatic exposure with delayed action part 42b of cam 42 moves (by means of pin 43a) pinion 48 into engagement with toothed portion 49 of ring 50 so that the running down of ring 50 before pin 72 releases the shutter is delayed. Also pin 53 is situated in part 57 of slot 58 by means of part 52a of cam 52 thereby preventing rotation of ring 50 until lever 54 is pivoted anticlockwise by pin 59 on rod 60. For flash exposure with delayed action pin 43 is against part 42a of cam 42 and pinion 48 is again brought into contact with teeth 49, and cam 38 moves lever 39 so that it meets pin 41 and prevents ring 3 from rotating. For flash exposures without delayed action pin 43 is against part 42c<1> and pinion 48 and teeth 49 are disengaged. The same applies to exposures but in this case cam 38b rotates lever 39 until it rotates ring 3 (by means of pin 41) to the position in which lever 7 engages recess 6a.
