IPC: B26F1/38
Filed: 1971-05-27
Abstract: 1295020 Sharpening machine cutters in situ KARL REICHERT GmbH [trading as KRAUSS U REICHERT SPEZIALMASCHINENFABRIK] 27 May 1971 [27 May 1970] 17552/71 Heading B3D [Also in Division B4]  A machine for cutting a pile of cloth 12 comprises a reciprocable knife 18 and a reciprocable sharpening head 29, the head 29 including two levers 57, 58 pivotable transversely of the reciprocation to bring grinding means into contact with respective sides of the knife 18 under the control of an element 63, acted on by an adjustable brake 66-73 during head reciprocation to act through a linkage for grinding one side or the other of the blade 18 according to the stroke direction of the head 29. The head 29 pivotably supports a linkage lever 61, the control element 63 being adjustably locked to a pin 62 of the lever 61 by a set screw 64 cooperating with one of a range of depressions 65. On a downward stroke of a bar 27 supporting the head 29 for reciprocation, the element 63 is drawn between parts 69, 70 of the brake, against the action of a spring 66. The lever 61 is thus urged by the drag of the brake to pivot about its mounting, a slot 60 in its lower arm acting on a pin 59 to pivot a double lever 56 about a bushing 30. The lever 58, rigid with the double lever 56, thus urges a grinding belt 43 into engagement with the knife 18 against the action of a spring (51), Fig. 2 (not shown). On the return stroke of the bar 27, the brake acts on the element 63 in the opposite direction, corresponding pivoting of the lever 56 applying a grinding belt 42 to the knife 18 by means of the lever 57. Drive for the belts 42, 43 is supplied by a shaft 26 through a telescopic connection and gears 33-35, (36), and the element 63 has inoperative portions of reduced cross-section at each end to limit the extent of the grinding operation. In a modification, Fig. 5 (not shown), the element 63 is connected to the pin 62 by means of an axially locked rotatably adjustable sleeve (76) on the element 63, a set screw (78) of the pin 62 being engageable with a helical groove (77) of the sleeve (76). In an alternative construction, Fig. 6, the grinding means comprises wheels 98, 99 on respective arms 91, 92 forming the two levers.

Abstract: 1296567 Colour television receiver INTERNATIONAL STANDARD ELECTRIC CORP 10 Sept 1970 [13 Sept 1969] 43282/70 Heading H4F A PAL receiver colour switch and colour killer comprises a bi-stable multivibrator, negatively directed horizontal flyback pulses being applied via capacitor 9 to one input E1 and via capacitor 3 and resistor 4 to the other input E2 to which is also applied via capacitor 5 and resistor 6 a sinusoidal voltage of half line frequency derived from received swinging colour bursts, and via a resistor 2 a positive potential + U v  which raises the amplitude required to trigger the multivibrator. The phase of this sinusoidal voltage is such that its maxima coincide with the horizontal flyback pulses and its amplitude is such that when it is added to the flyback pulses the multivibrator is triggered. The PAL receiver colour switching signal is taken from the collectors of the multivibrator's transistors. When there is no colour transmission the colour bursts are absent, the multivibrator remains in one of its two staple states and instead of an average-value voltage being present at points Al and A2 one will be at zero potential and the other at the supply potential, and either of these may be used to block the receiver's colour channel. The time constants of the RC circuits 10, 11 are chosen so that there is no appreciable change in the voltage at points A1 and A2 during the vertical flyback even though the multivibrator is stopped due to the absence of the colour bursts. Alternatively to ensure that no colour killer action takes place during the vertical flyback, negative vertical flyback pulses may be applied via capacitor 7 and resistor 8 to the input E2 which together with the horizontal flyback pulses trigger the multivibrator.

Filed: 1969-12-29
Abstract: 1337258 Adjustable beds STAFFORD PATENTS & HOLDINGS Ltd 22 Dec 1970 [29 Dec 1969 2 March 1970| 63107/69 and 9912/70 Heading A4J A bed frame providing for lifting and tilting of the mattress comprises a platform 1, 2 with rollers or other means slidably engaging uprights 4..7 of a supporting frame 8..11, the platform being suspended from the uprights by a flexible member or members passing beneath it, being raised or lowered by operating means which alter the effective length of the flexible member(s), and being tiltable by a second operating means. An adjustable head-rest may be provided, and may be operatively connected to the tilting means. In one form, a tape is attached to the top of each upright of the frame and wound on a roller mounted on the platform and guided in the upright. In the form shown in plan in Fig.1, the tapes 28 at the head end of the bed pass under pulleys at the corners of the platform and then round guides 30, 31 and pulley 33 to an anchorage 34, all on the underside of the platform, and the tapes 29 at the foot pass round guides 35, 36 to the pulley 33 and anchorage 34. The pulley 33 is carried by the piston-rod of a hydraulic actuator 42, worked by a hand or foot pump, whereby the effective length of all the tapes is simultaneously altered to lift or lower the platform. The guides 36 for the foot-end tapes are carried by a member 37 actuated by screwed shaft 39 with handle 41, to lift and lower the foot of the platform only, to tilt it. The raising and tilting mechanisms described may be replaced by electrically-driven mechanisms The mattress base-board (which rests on the platform) has a head-end section 48, Fig.7, hinged to the main part 46 and raised by extensible arms 55 hinged to the head section at 51 and rigid with a shaft 60 actuated by cable 62 fixed to the base-board 46 and wound on a shaft 64 by a handle 65: the cable thus simultaneously raises the head section 48 and moves the part 46 to the left. The member 37, Fig.1, may also be connected, for example by cable 66, Fig.7, to the head-rest mechanism so that the foot of the bed is lifted as the head-rest is raised. In another embodiment, Figs.8 and 9 (not shown), the suspending tapes (90) pass over guides (81, 82) on a sub-frame (87) to anchorage on the platform, the sub-frame being slidable on the underside of the platform by a screwed shaft (84) with a handle (86) to vary the effective length of all the tapes and the anchorage of the foot-end tapes comprising a shaft on which these tapes can be wound to tilt the platform.

Title: Gain controlled amplifier
IPC: H03G3/30
Filed: 1971-05-13
Abstract: 1343467 Automatic gain control in transistor circuits RCA CORPORATION 13 May 1971  [19 May 1970] 14773/71 Heading H3T A gain-controlled amplifier circuit has a first transistor connected as a gain-controlled first common-emitter amplifier stage, and a second transistor connected as a second common-emitter amplifier stage, the stages being arranged for connection in parallel with each other and the first stage having greater maximum gain and less minimum gain than the second stage. A television receiver comprises tuner 26 including R.F. and mixer stages, a first I.F. network 28 feeding into a first I.F. amplifier, the output of which is fed via second I.F. network 30 to subsequent I.F. stages 14, video detector 16 and first video amplifier 18. The first I.F. amplifier comprises cascaded emitter-followers 56, 58 and a cascode amplifier comprising double-emitter transistor 64 in common base connection, the first emitter being coupled to the collector of a high gain transistor 62 in common emitter connection, and the second emitter to the collector of a low-gain transistor 66 which is provided with emitter circuit degeneration by means of resistor 70. The collectors of transistors 56, 58 and base of transistor 64 are biased by means of a dynamic noise filter 50, described in Specification 1,290,092. An A.G.C. voltage is derived from the video signal by means of a keyed A.G.C. circuit 20 of the type described in Specification 1,290,091 and is applied to the base of a transistor 98. The collector of transistor 98 is coupled into a bias network 36, 44, 42, 40 so that variation of the current in this transistor varies the bias on emitter-follower 56 and hence on emitterfollower 58 and amplifier 62. The emitter of transistor 56 is also coupled to the base of a transistor 72 the collector of which is coupled via emitter-follower 80 to the base of double-emitter transistor 82, one emitter of which is coupled back by a negative feedback loop to the base of transistor 72; it is also coupled via a potentiometer network 68, 70 to control the bias on transistor 68. This second A.G.C. control circuit is provided with an adjustable delay, by means of potentiometer 46. The second emitter of transistor 82 provides a delayed A.G.C. potential for the R.F. amplifier, via amplifier 90. At high signal levels emitterfollower 56 is cut off and thereafter acts as a varactor diode, by virtue of the base-emitter capacity 56d; this, with resistor 76 forms a variable attenuation network which gives a further range of gain control. The Specification also describes an integrated circuit construction comprising the transistors 52, 62, 64 and 66 (Fig. 2, not shown).

Title: Electronic control apparatus

Filed: 1972-05-12
Abstract: 1345651 Control of DC motors H MIZOULE 12 May 1972 22349/72 Heading H2J [Also in Divisions G1 and A6] A control circuit for a device such as a D.C. motor is operated in response to the displacement of an electrostatic charge in the vicinity of a pick-up A. In the arrangement of Fig. 2 the supply circuit of motor M is controlled by a bi-stable circuit of SCRs T3 and T4. Normally FET T2 is conducting and the potential on the gates of SCRs T2, T4 is such that they are non- conducting and the motor M is not energized. If an electrostatically charged rod is now placed adjacent pickup A the displacement of the charge thereon switches off the FET T2 so that the rise in potential at the anode switches on SCR T4. The supply circuit is thus connected to the motor M. If the charged rod is again brought up to the pick-up A a second time SCR T3 is rendered conducting and SCR T4 is blocked by the discharge of capacitor C2 so that the supply of current to motor M is open-circuited. Instead of using a bistable arrangement only one SCR may be used, Fig. 1 (not shown), in which case a switch operated by the motor after a predetermined time is utilized to shortout the SCR and subsequently disconnect the motor from the supply. The motor may be incorporated in a toy vehicle, animal or doll, see Division A6, and if these are made of plush or like synthetic material the FET may be operated by movement of the hand instead of the rod.
