Title: Improvements in and relating to control means for sliding sashes and shutters for windows and the like
IPC: E05F11/38
Filed: 1938-09-26
Abstract: 519,648. Operating - mechanism for windows and shutters. ETABLISSEMENTS G. KLEIN & CIE. Sept. 26, 1938, No. 28051. Convention date, Sept. 25. 1937. [Class 20 (iii)] The operating-mechanism of a sliding sash or shutter comprises at least two control members which are so arranged that either of the said members can by itself alone and through mechanical connections only, effect the movements of the sash or shutter in both directions, and means are included in the gearing connecting the control members with the sash or shutter by which one control member remains immovable when the other control member is being operated to raise or lower the sash or shutter. The sash 2 shown in Figs. 1 and 2 slides in guides 4 and is operated by driving mechanism or rack-andpinion' type 7, 8 provided at each side of'the window. Each pinion 8 is provided with an integral socket 11 which is engaged by the spindle 12 of an operating handle or wheel 9 with an interposed expanding spring 10 carried on a sleeve 13a on the spindle 12; the handle 9 cannot be operated by the pinion 8, but, when the handle 9 is rotated, a catch 13 on the spindle 12 causes the spring 10 to expand and grip the socket 11, thereby driving the pinion. Alternatively, the mechanism may be such that actuation of the crank causes a peg moving with the crank to effect temporary coupling with the member to be driven, such as the socket 11. The sash may be locked in any position by mechanism operated by a separate handle 15. Alternatively. the locking mechanism may be adapted to be released automatically whenever either of the cranks is operated ; for example, the relative displacement, when the crank is operated, of two members mounted coaxially with the spindle 12 may be used to cause the projection of a peg controlling from a distance the locking mechanism. In the mechanism shown in Fig. 4 there is provided a single rack-andpinion device 7, 8 which may be operated from either of two control handles 9 through a differential gear system 23, and pinions 24, 25. The handles 9 are at opposite sides of the window and are each connected with the shafts 22', 22<2> of the differential gear by worm-andworm-wheel gearing 20, 21, which, although it allows the transmission of the drive by the worms from the cranks. does not allow the transmission of a reverse drive from the differential gearing by the worm-wheels to the worms and cranks. The shaft 22<1> may be in two parts which are normally connected together by a clutch, but when disconnected by operating the spring-controlled push-rod 30 enable the sash to be operated by hand. The rack and pinion 7, 8 of Fig. 4, may be replaced by a chain drive as shown in Fig. 7 ; the chain 32 which is driven by a pinion 33 and slides in casings 34, 35 is provided with a cross-bar 36 which is attached to a plate 37 fixed to the sash. The window may be provided with a balancing system including a roller which is carried by an arm and bears on the lower cross-bar of the sash.

Title: Distant electric control device
IPC: G08C19/38
Filed: 1928-10-01
Abstract: 300,608. Granat, E., and Compagnie des Forges et Acieries de la Marine et d'Homecourt. Nov. 16, 1927, [Convention date]. Controlling extent of travel.-In distant control arrangements for moving guns or other objects where a working motor R, Fig. 1, arranged to run synchronously with a distant transmitter T may accidentally get out of step, the lag or lead is automatically corrected by imparting rotation to the motor field in response to movements of hunting switches 27, 44, 59. One element of each hunting-switch receives movement from one of a set of auxiliary transmitters 18, 19, 20 related to corresponding auxiliary receiving motors 21, 22, 23 in the same way as the main transmitter T is related to the main motor R ; the other element of each hunting-switch is driven by the controlled object. The hunting- switches remain in the zero position shown in the drawing so long as synchronism persists between R and T. If there is a lag or lead, the switches temporarily make a circuit to an electromagnet 67 which closes a reversing-switch 68 for starting a correcting-motor S adapted to rotate the previously stationary field of the main motor R, this action continuing until all the hunting-switches are again at zero. Several switches, all connected in series with the electromagnet 67, are suitably geared up and geared down in relation to the main transmitter so that they act successively to determine correction with increasing degrees of accuracy. The synchronizing arrangement between the main transmitter and the main motor may be of the kind described in Specifications 174,082, [Class 40 (i), Electric signalling systems &c.], and 260,579. In a modification adapted to the distant control arrangement described in Specification 267,100, correction is obtained by feeding the stator of the main motor with three. phase currents producing rotation of the resultant field. In a further modification the several hunting-switches are connected in parallel instead of series, and control separate reversing switches for the motor performing the corrections. The invention is applicable to the simultaneous control of a number of guns at different firing-stations and may include limitswitches for breaking the circuits of the correcting-motors independently of one another so as to suit different firing-zones.

Abstract: 1,037,319. Counters. VACUUMATIC Ltd. July 17, 1964 [July 16, 1963], No. 28191/63. Heading B6B. [Also in Division G4] Apparatus for counting sheets by turning up their corners comprises an incomplete drum 16 rotating in one sense and a suction head 24 rotating in the opposite sense about an axis parallel to the drum and rotating with the drum. The drum is positioned over a corner of a stack of sheets 43. The suction head 24 lifts the corner which rides over edge 16a of the drum. Suction is then cut off, the corner is lifted until it rides on the top of the drum, Fig. 5f. Counting is effected at 107 by a magnetically-operated switch 108, Fig. 1, which counts the rotations of a driving shaft. Counting is disabled if no sheet interrupts the path from a light 38 through slots 5 and 6 to a photo-electric cell 39. The relative position of suction head 24 and drum 16 is adjustable, an early pick-up being used for flexible sheets. The position of the counting-separating head relative to the stack is adjustable by a double screw 104 controlling rollers 96, Fig. 6. As the head turns up the corners it descends the stack by a screw-thread drive (Fig. 3, not shown) driven in synchronism with the counting head. The rollers 96 strike the bottom plate before the whole of the stack has been counted, fork arms 95 then swinging up to permit continuation of the count. A photo-electric cell 82 disconnects the drive if no sheets lie in the path from a light source 83.

Title: Improvements relating to vehicle steering mechanisms
IPC: B62D3/08
Filed: 1949-11-04
Abstract: 684,768. Loocking rods. BURMAN & SONS, Ltd., and BRIGGS, W. H. Oct. 17, 1950 [Nov. 4, 1949; Feb. 3, 1950], Nos. 28252/49 and 2810/50. Class 80 (iii). In a vehicle steering mechanism the drop arm shaft a operated from a steering worm c is provided with two freely rotatable discs o between collars h, fixed on the shaft which co-operate respectively with fixed friction pads s, s<SP>1</SP>. The shaft is mounted with a small amount of lateral play at its end in the casing cover t and the discs o have wedging balls q between them engaging in tapered recesses and are acted upon by springs r so as to maintain a light contact with the collars h. On force being transmitted from the road wheels in either direction the shaft a moves laterally to increase the pressure of one of the friction pads on its disc o, and relieve the pressure of the other. This results in a jamming action of the balls q tending to lock the discs o against the collars h and prevent the forces being transmitted to the steering wheel. For normal steering forces from the steering wheel the shaft a moves in a direction to bring the opposite friction pad into action which has the effect of relieving the locking action. Instead of the balls q working in recesses in the discs o the discs may be provided with interacting tapered teeth which serve the same purpose. Additional friction plates may also be provided. Specification 654,326 is referred to.

Title: Circuit arrangement for flashing light installations
IPC: H01Q21/12
Filed: 1970-06-11
Abstract: 1,244,960. Road traffic signals on vehicles. WESTFALISCHE METALL INDUSTRIE K.G. HUECK & CO. 11 June, 1970 [16 June, 1969], No. 28365/70. Headings G4F and G4Q. Front and rear direction indicator lamps BLv, BLh are flashed by a flasher unit comprising transistors T1, T2, resistors R1 . . . R4, condenser C and relay A, acting as an astable multivibrator, when a direction indicator switch F is operated to engage contact L or R. The relay contact a which flashes the lamps BLv, BLh is shunted by a resistance R5 so that during the "dark" phase of the flashing when the contact a is open the resistance is in series with the lamps to produce a voltage drop, the current then flowing through the lamps being too small to illuminate them. This voltage drop is used in a control circuit comprising transistors T5, T6, diodes D4, D6 and resistances R6 . . . R9 to indicate failure of an indicator lamp by causing the multivibrator to operate at a higher frequency. Thus, failure of a lamp BLv or BLh causes an increase in the voltage drop across the resistance R5 so that transistor T5 becomes non-conductive whereupon transistor T6 becomes conductive and the voltage to which the frequency-determining condenser C is charged during the dark phase becomes smaller owing to the voltage division between the resistances R4 and R6. A pilot lamp K connected between contacts L, R flashes at the rhythm of the multivibrator. The rear indicator lamps BLh are connected in series with resistances R10, R11 shunted by contacts b1, b2 of a relay B. On closure of a switch S by switching on the normal vehicle lights the relay B is energized and operates in synchronism with the multivibrator so that for night driving, during the periods when the contact a is closed, the contacts b1 b2 are open and the resistances R10, R11 are effective to dim the lamps BLh. However, during the dark phase when the contact a is open, the contacts b1 b2 are closed and the resistances R10, R11 are ineffective. Hence the voltage drop across the resistance R5 during the dark phase is not affected by the resistances R10, R11 to give a false indication of lamp failure. In modifications (Figs. 2-4, not shown) the relay B and switch S are connected differently in the circuit.

Abstract: 694,656. Fluid-pressure servomotor-control systems. CLAYTON DEWANDRE, CO., Ltd. Nov. 21, 1951 [Nov. 21, 1950]. No. 28432/50. Class 135 [Also in Group XXXIV] A hydraulic servomotor in a control system of the kind wherein free circulation of liquid through the system can be interrupted to set up a pressure to actuate the servomotor, and wherein a hydraulic accumulator may augment the pump supply to the servomotor or entirely supply it should the pump fail comprises for the operation of, e.g. vehicle brakes, a casing 6, Fig. 2, having an inlet 22 from a pump 2, Fig. 1, an outlet 21 to a reservoir 3 and an inlet port 30 from an accumulator 5. The casing houses a plunger 9 having passages 10, 11 through which liquid normally flows from the pump to the reservoir 3, and a servomotor piston 16 having passages 32, 27 for connecting the accumulator port 30 with a chamber 23. The piston 16 slidably mounts a valve device 14 having a first valve member 13 co-operable with the plunger passage 11 and a second valve member 17 controlling communication between the piston passages 32, 27. Upon operation of a brake pedal 8, the plunger 9 engages the valve member 13 to interrupt liquid flow between the inlet 22 and the outlet 21 and so create a pressure in the chamber 23 to move the piston 16 to the right and, through a rod 26, apply the brakes. Should the pump run too slowly to develop sufficient pressure to fully operate the brakes or fail altogether, further pressure applied to the brake pedal unseats the valve member 17 to connect the accumulator 5 with the chamber 23 to operate the piston 16.' The accumulator 5 is charged with pressure liquid by the pump up to a pressure determined by an unloader valve 4 which then opens to pass the excess liquid through the system to the reservoir until such time as the plunger 9 seats upon the valve member 13.
