Filed: 1960-05-11
Abstract: 948,449. Pick-finding mechanisms. L.STRACH. May 11, 1960, No. 16571/60. Heading D1E. The invention concerns a pick-finding mechanism in the kind of loom which stops at front centre on weft fault with the jacquard cylinders already turned on for the next shed but with the hooks and griffe engaged for the last shed so that, on "unweaving", it is necessary to turn back the cards initially twice, and thereafter once, per backward revolution of the loom. For normal weaving the cylinder is intermittently moved by a sleeve 22 having a pin 27 engaging a star wheel 37 and the presser frame 32 is moved by a cam lift 30 on the sleeve 11. On "unweaving" the sleeve 22 is moved axially to disengage the pin 27 and cam 30 and to engage a rephased cam 31 with the presser frame 32. During the first pick of unweaving two pins 28,29 successively turn the card cylinder star wheel 37 and then the sleeve 22 is moved (not fully) back axially so that only the longer pin 29 engages the wheel 37 for each successive pick.

Filed: 1951-07-12
Abstract: 702,856. Jointer-planer work holder. FORD, R. S. July 12, 1951 [July 19, 1950], No. 16587/51. Class 145 (1) A work holder for a jointer-planer has two pressure elements acting in the same direction on the work, a rigid member connecting the two pressure elements, and a support for the rigid member mounted for limited movement to allow the pressure elements to move towards and away from the work ; the pressure elements being so arranged that when the work passes under the second pressure element the first element is lifted clear of the work. The front pressure element 1 is arranged to hold the work piece 28 whilst it is fed to the cutter 33 and the rear pressure element is comprised by two rollers, 2 and 3, which grip the work after the first part of it has been formed with a true under surface on which the wood is now located, the front element 1 being lifted off the work by the pivoting of the arm 10 about the axis 16. The pressure elements are urged on to the work by a spring 19 the end of which may be held in any one of a series of holes in a member 21 to adjust the tension. An adjustable stop 17 prevents the pressure elements from falling on to the guiding surfaces 32, 34 when the work piece is finished. The two pressure wheels 2, 3 are joined'by a rigid member 5 which is pivoted at 7 to the part 4 of the arm 10 and the member 5 is urged in a clockwise direction by spring 9 up to a stop 8. The effect of this is to distribute the downward pressure between the two wheels and a stable grip results ; however, the wheels 2 and 3 may be substituted by a single wheel pivoted directly on to the arm 10. In a modification, not shown, the arm 10 is carried on parallel motion linkage. The wheels 1, 2 and 3 may be set with their axes normal to the direction of the motion of the work piece or slewed thereto to force the work against the lateral guide. If the wheels are arranged normal to the motion of the work they may be encompassed by an endless belt and a power feed applied to one of the end wheels. Fig. 7 illustrates an additional member consisting of the wheel 124 which forces the work against the guide 6 by means of the spring 123 which is adjustable in the same manner as spring 19. An adjustable stop 26 is provided to prevent the wheel 124 falling against the guide fence 6 when the work piece is removed. The member 122 supporting the wheel 124 also acts to guard the cutter block. A kick-back stop consisting of an eccentrically arranged wheel in frictional contact with one or more of the pressure wheels may also be provided.

Title: Circuit arrangement for switching off after a predetermined time
IPC: H03K17/28
Filed: 1974-04-17
Abstract: 1455039 Transistor switching circuits; time control of receivers SABA SCHWARZWAELDER APPARATE-BAU-ANSTALT AUGUST SCHWER SOEHNE GmbH 17 April 1974 [18 May 1973] 16753/74 Headings H3T and H3Q In a circuit for switching off electronic equipment such as a radio 1 after a predetermined time by an electronic timer started by a keying switch 4 the timer comprises a first amplifier 13 having an integrating network including a capacitor 25 and a second amplifier 14 having its inverting input connected to the output of the first amplifier 13 and its output connected via a resistor 29 in a feedback path to its noninvesting input and the output of the second amplifier 14 is connected to the base of a first transistor 33 whose collector is connectible to the base of a second transistor 27 which has its collectoremitter path connected in parallel with the main on-off switch 2 of the electronic equipment 1. As shown the timing period is started by pressing the key switch 4 so as to momentarily engage contacts 7-9, c and d the movable contact of the switch 4 then returning to engage contacts 7-9 b and c. The collector-emitter of the transistor 27 is momentarily bridged by contacts 8c and 8d so as to turn on the radio 1 and a transistor 11 which connects the battery 3 to a stabilizing circuit 12 which stabilizes the supply voltage for the timing circuit at half the battery voltage UB. The momentary contact of contacts 7c and 7d causes a potential lower than a reference potential applied to the inverting input of an operational amplifier 13 to be applied to the non inverting input of the amplifier 13. The subsequent engagement of the contacts 9c and b cause transistor 27 to turn on so as to maintain the radio 1 and the transistor 11 on. After the predetermined time the output voltage determined by 25 and 24 from the amplifier 13 reaches a predetermined value and the output from the amplifier 14 changes positive. This causes transistor 33 to turn on to switch off the transistor 27 and the radio 1 and so end the timing period. During the timing period which can be an hour an ammeter 28 indicates the time still remaining until switch off. If the slider of the potentiometer 24 is set to its upper stop the meter 28 reads half the battery voltage when the timing circuit is switched on so that the meter gives an indication of the on load condition of the battery 3. In the off position 2 of the timing switch 4 the meter 28 is connected as a timing indication with contacts 5a and 6a connected to a discriminator voltage.
