Title: Improvements relating to machinery and drive means therefor
Inventor: MCKAIN JOHN ANDREW
IPC: F16D11/06
Filed: 1967-03-15
Abstract: 1,217,512. Positive clutch control; machinery guards. J. A. McKAIN. 13 March, 1968 [15 March, 1967; 11 April, 1967; 3 June, 1967], Nos. 12050/67, 16411/67 and 25722/67. Headings F2C, F2J and F2L. In a positive clutch for a press wherein a clutch element 27 carried by a driven shaft 21 is spring biased into engagement with a driving wheel 24, a control sleeve 36 rotatable with the driven shaft 21 has a cam surface 47 or cam follower which co-acts with the clutch element 27 and moves the latter to a disengaged position when the control sleeve 36 is held by a pneumatically operated friction brake (55). As shown a radially slidable clutch key 27 is pressed by a spring 30 into a recess 29 in the driving wheel 24. A tension spring 41 normally rotates the control sleeve 36 with the driven shaft 21. When the brake (55) is applied to the control sleeve 36 continued rotation of the driven shaft 21 causes the clutch key 27 to ride down the cam 49 and disengage from the wheel 24. A pin 38 and slot 39 limits lost motion between the driven shaft 21, and control sleeve 36. On release of the brake (55) the spring 41 rotates the sleeve 36 relative to the shaft 21 until the cam slot 45 is aligned with the clutch key 27 to permit re-engagement. In Fig. 7 (not shown) an axially slidable clutch sleeve (82) splined to the driven shaft (21) is pressed by a spring (84) to engage teeth (83) on an end thereof with complementary teeth (81) on the wheel (24). A pin on the control sleeve (36) co-acts with a cam surface on the clutch sleeve (82) to disengage the clutch when the control sleeve is held by the brake (55). In Fig. 9 (not shown) an axially slidable clutch key (100) carried by the driven shaft (21) is pressed by a spring (101) into engagement with a recess in the wheel (24). A cam (102) on the control sleeve disengages the clutch key (100) from the wheel (24) when the control sleeve is held by the brake (55). In Fig. 10 (not shown) the tail (112) of a rotatable segmental clutch key (110), which connects the shaft (21) and wheel (24), coacts with a cam on the control sleeve to disengage the clutch. Interlock with guard.-A guard (Fig. 1, not shown), for the press is mechanically connected to a lever 63 carrying a projection 65. When the clutch is disengaged recesses 68, 70 in a flange 25 of the driven shaft 21 and control sleeve 36 are aligned and permit entry of the projection 65 during raising of the guard. Thereafter the projection 65 prevents clutch engaging relative rotation between the control sleeve 36 and driven shaft 21 until the guard is lowered. Initial movement of the guard may energize the brake 55.

Title: Improvements in and relating to arrangements for the transmission of signals from train to track
IPC: B61L13/04
Filed: 1930-08-29
Abstract: 361,447. Track apparatus actuated by trains. VEREINIGTE EISENBAHNSIGNALWERKE GES., Siemensstadt, Berlin. Aug. 29, 1930, No. 25863. Convention date, March 18. [Class 105.] For the transmission of a signal from a train to track apparatus, in which an iron mass on the train acts on an inductance-capacity circuit on the track, the circuit is made resonant. The invention is applicable to axle counters actuated by the iron of the wheels and to end-carriage indicators actuated by an iron core carried at the end of the train. Fig. 3 shows the latter arrangement, comprising a core 11 which influences the resonant circuit 13, 14 to actuate a relay 16 the armature 17 of which closes a point in the circuit of a direct current relay 18. The direct current circuit also includes a contact 20, closed by the train, which may be a slow-release treadle contact or an insulated rail. Fig. 2 shows the resonant circuit current as a function of the capacity, curve 8 showing the current with the iron mass in the field of the inductancecapacity circuit and curve 7 showing the normal current with the iron mass absent. By slightly de-tuning the circuit by choosing a capacity value a or b it will be seen that an increased current difference is obtained for actuating the relay. With a capacity value a the relay armature drops on the circuit being influenced, while with a capacity value b the relay armature is attracted. The resonant circuit relay may be a gaseous conduction lamp.

Filed: 1975-06-18
Abstract: 1491107 Measuring blood pressure B SPEIDEL 18 June 1975 [18 June 1974]  25997/75 Heading G1L In an instrument for measuring blood pressure, in particular the systole and diastole blood pressure of a patient, two indicators 12, 21 are moved by a pressure gauge 2. The movements are effected via lever converter 3 with follower arm 5 and-an  associated gear system including an arcuate pivoting member 6 and a pinion 9. The indicators 11 and 21 are immediately immobilized at the above pressure points by activating electromagnets 19, 29 which act upon locking members 18, 28 which are attached to shafts 12, 22. Thus play between the angular positions of the parts interlinked by teeth is no longer included in the measurement. The pressure gauge 2 is connected to the pressure cuff or sleeve that is affixed to the patient. During measurement, as the pressure rises, the indicator 21 is pushed around by a follower arm 31 attached to the indicator 12. When the pressure is allowed to decrease the arms tend to be rotated in the opposite direction by the action of the return springs 16, 26 until each of the electromagnets 19, 29 are actuated at the pressure points. Various modifications, Figs. 2, 3, (not shown) are described dealing with the positioning of the locking members, the associated magnets and concerning braking discs that may be included on the locking member with associated faces that are roughened, knurled or friction coated.

Title: Methods of and  systems for sharpness in the reproduction  of continuous-tone pictures
IPC: G03F1/00
Filed: 1973-05-31
Abstract: 1424410 Facsimile DR-ING RUDOLF HELL GmbH 31 May 1973 [2 June 1972] 26071/73 Heading H4F In a facsimile system using an edge enhancement or sharpness signal, said signal is or is not added to the normal video signal in dependence on the pictorial content of the original picture; thus in a colour facsimile system flesh tones are left unsharpened, and/or areas of high contrast or detail are left unsharpened. A colour original 2, mounted on a rotating transparent drum 1 is spirally scanned by means of light source 12, and optics 13, 14, 18, 20, and the modulated light from the original is split into component colours by dichroic mirrors 23, 24 and photo-detectors, 25, 26, 27. The outputs of the photo-detectors are fed to a colour analyser 71 and also to a component selection switch 38 whereby a reproduction of a selected component may be produced photographically at 5 using modulated light source 41. A cathoderay tube 28 produces a circular scan image 30 which is used to scan an area of the original surrounding the spot 19 scanned by the main beam, and gives a voltage across capacitor 46 fed by photodetector 34, indicating the average brightness value of the scanned area. The difference between this average value and the brightness of the spot 19 gives a sharpness signal representation and is produced by differential amplifier 48 receiving the output of photo-detector 27 and the voltage across capacitor 46. The amount of detail in the area surrounding scanned spot 19 is given by the A.C. output of photo-detector 34 and is used via detector 58 to block transistor 50 passing the sharpness signal when the area is determined to be already detailed enough. If transistor 50 is not blocked, the sharpness signal proceeds to transistor 53 which is controlled by colour analyser 71. On detecting a combination of colour component amplitudes giving, e.g. a flesh tone, analyser 71 blocks transistor 53. If transistor 53 is not blocked, the sharpness signal is added to the component signal at the output of switch 38. A second sharpness signal is produced by double differentiation of the output of photo-detector 27 and is fed via transistor 91 for combination with the component signal. Transistor 91 is controlled by the detected output of photo-detector 94 which scans a mask 4 indicating areas 85 in which the sharpness signal is to be added. Transistor 91 is therefore enabled for these areas.

Abstract: 506,370. Supply meters. BRITISH THOMSON-HOUSTON CO., Ltd. Sept. 7, 1938, No. 26161. Convention date, Sept. 9, 1937. [Class 37] In order to make a, multiple-element or polyphase meter comparable in size with a single-element meter, the driving magnets are arranged around the peripheral portion of the armature disc and the brake magnets are arranged nearer the shaft. As shown in Fig. 1, a three-phase induction meter has the three driving-elements 11, 12, 13 arranged around the periphery of the disc 10, the central portion of which is acted on by brake magnets 14. The aluminium disc 10 may be made of several disc layers stacked one above the other, each layer having segments insulated from each other by slits 19 and the segments in different layers overlapping. Currents induced in different disc segments are thereby prevented from spreading so as to cause interference between different driving elements. The central portion of the armature is provided with auxiliary copper discs 24, 25, Fig. 2, to increase the conductivity. Four permanent magnets 14 are arranged above the disc and four below it so that opposite poles face one another above and below the disc. They are secured to magnetic supporting plates 22, 23 at the ends remote from the armature. Two magnets on each side of the armature have north poles facing the disc, the other two having south poles facing the disc. The plates 22, 23 may be extended outwards to support the driving elements. To adjust the damping, an iron ring 27 forming a magnetic shunt surrounds each set of four magnets and is supported by bolts 28 and guide rods 26. The lower step bearing 33 is screwed into the plate 23, the upper bearing being carried by a bridge-piece attached to the upper plate 22. Specification 424,746, [Goup II], is referred to.
