Abstract: 1,257,449. Draft regulating device. KLOCKNER-HUMBOLDT-DEUTZ. AG. 9 Jan., 1969 [9 Jan., 1968], No. 11866/71. Divided out of 1,253,411. Heading A1P. A draft regulating device for a hydraulic power lift of a tractor comprises a link 53 which, when the work resistance of an implement increases, tilts a lever 50 moving a control device 40 thereby moving a valve spool from neutral (N) to lift (H). A pump 59 supplies fluid, via a non-return valve 65 to a power lift cylinder 64 thereby raising the implement. Simultaneously, fluid enters an annular chamber 45 and forces a piston 42 against spring 44 which switches the valve spool to neutral. Fluid now seeps through a throttle 46 to a reservoir 61 allowing the level 50 to regain its original position if the working resistance is at its required level, if still too high, the cycle is repeated. If the working resistance decreases, the lever 50 tilts in the opposite direction, causing the valve spool to move to its "lower" (S) mode. Fluid now flows from the cylinder of the power lift 64 via ducts 63, 66 to the reservoir 61, thereby lowering the implement.

Abstract: 1,258,225. Master cylinders. ALFRED TEVES G.m.b.H. 16 July, 1970 [23 July, 1969], No. 34474/70. Heading F2F. A master cylinder for a dual-circuit hydraulic brake system including a brake force booster which utilizes an auxiliary pressure in such a manner that upon brake actuation the auxiliary pressure is applied to the effective surface 10 of the master cylinder piston 4 by the opening of a valve 19, the piston and a control slide 16 are slidably arranged one behind the other in a cylindrical housing 1, a first chamber formed between the slide and the piston including the effective surface of the piston is connectible to one brake circuit 15 and a second chamber 5 disposed at the end face of the piston opposite to that adjacent the slide and is connectible to the other brake circuit. The valve 19 is arranged in the slide via which a connection is provided, when the valve is open, between a connection port 22 for the source of auxiliary pressure and the first chamber and the valve co-operates with a cut-off valve 14 which controls, the passage of the pressure medium between the first chamber and a reservoir, connected at port 7, via bores 12, 13 in the piston, in such a manner that the valve 19 opens when the valve 14 closes and vice versa. As shown, the piston 4, biased by a spring 3 on to a shoulder of the cylinder housing 1, has a peripheral recess to form a chamber 8 in communication via a bore 9 with a reservoir connection 7 and the bore 13 connecting with the bore 12 which is provided with a conical seat which co-operates with the conical valve head 14 coupled to the conical valve head 19 seated within a chamber 18 of a control slide 16 and connected via bores 17, 20 to a chamber 21 surrounding the slide. The chamber 21 communicates via bore 22 with one chamber of an accumulator 2 which chamber receives hydraulic pressure medium pumped from the reservoir; the other chamber of the accumulator is filled with pressurized gas. When the control slide 16 is moved to the right as seen in the Figure, the valve 14 seats in the bore of the piston 4 and the valve 19 opens to allow passage of pressure medium from the accumulator to the chamber between the control slide and effective face 10 of the piston 4 and to the brake connection 15; the pressure medium acts on the piston 4 also to compress the medium in the chamber 5 and to operate the brakes on a second axle. In modifications, (a) the accumulator instead of being integral with the cylinder housing as shown is screwed to the housing, and (b) the valve body is carried by a rubber plate which is compressed at the edge thereof by a piston so as to yield at the centre in the direction of the control slide movement and thereby add to the accumulator pressure.

Abstract: 1,258,618. Aircraft cabin pressurization system. INTERCONTINENTAL DYNAMICS CORP. March 14, 1969, No. 13445/69. Heading G3P. In an aircraft cabin pressure control system, the main control valve 12 has a reference chamber 75 connected via restrictor 60 to static ambient pressure port 1, and a bellows 42 controls air leakage via pilot valve 55 into chamber 75 in response to cabin pressure. Before changing altitude, the new altitude is selected on indicator 25 by rotating knob 35 and gears 32, 29. This causes pin 30 on gear 29 to move relative to pin 49 on a further gear 44 thereby tensioning spring 50 via one or the other of the spring ends 50, 51. The subsequent movement of pin 49 (and gear 44) by the spring back into alignment with pin 30 is controlled by escapement 48, and this movement causes axial movement of the end 41 of bellows 42 through screw threads thereby maintaining the rate of change of cabin pressure less than the rate of change of altitude. Valve 12 includes safety pilot valve 78 and is controllable alternatively by 3-way manual valve 15 upon selecting manual control by valve 14. An auxiliary valve 13 is controlled by a safety pilot valve and a solenoid valve 93. (For Figures see next page)

Abstract: 1297774 Optical prisms PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 3 Dec 1969 [6 Dec 1968] 59069/69 Heading G2J [Also in Divisions H3 and H4] In a time delay device acoustic or light waves are propagated through a triangular-shaped prismatic body ABC along a multi-section path, indicated by arrows, extending between an input T 1  and output T 2 . The angles A, B are in the range 45 degrees-60 degrees and preferably are 48 degrees. The multiple reflections of the wave path ensure that slight inaccuracies of the angles A, B do not adversely affect the properties of the path. Thus in the instance where the waves are acoustic and T 1 , T 2  comprise piezo-electric transducers, a wave entering perpendicularly at T 1  emerges perpendicularly at T 2  and the delay time is not disturbed. In the instance where the waves are light waves an incident beam striking the surface AB at an agle other than a right angle emerges from the same surface in a beam parallel to the incident beam. The body ABC may be of glass or may comprise a vessel containing a liquid. If phase or amplitude modulation of the light beam is required the body is made of a material having a refractive index which may be varied; for example, the material may be potassium dihydrogen phosphate the refractive index of which may be varied by the electric field strength applied thereto.

Abstract: 1309763 Moulding opening and closing mechanism H ERLENBACH 16 March 1970 12607/70 Heading B5A In a moulding machine, of particular use with foamed plastics, comprising a pair of central mould parts carried by member 1 and a pair of outer mould parts 2a, 2b, reciprocable into and out of engagement with the central mould parts to define a pair of closed moulds, the outer mould parts are actuated through bent levers 6a and 6b by rotatable arms 5, the arms being pivoted at their centres to a drive shaft 7 passing through the member 1, preferably in a sleeve 8. Each lever is journalled to its associated outer mould part by a sleeve 10 rotatably mounted within the lever, which sleeve is itself eccentrically rotatably mounted upon a pin 9a or 9b carried by the mould part. The ends of the levers are split and clampable to the sleeves 10. In use the length of levers 6a and 6b are effectively altered to change the stroke and thus closing pressure of the machine by unclamping the ends of the levers, rotating the sleeves to the desired position, and then reclamping the levers. In the closed position of Fig. 2, which is reached by clockwise rotation of arms 5 from the position of Fig. 1, all the pivot pairs lie in a straight line. Partly due to this and partly due to the fact that further clockwise movement of arms 5 is prevented by abutment of levers 6a and 6b with one another, the position of Fig. 2 is rendered self locking. If desired the arms 5 may overrun the position shown in Fig. 2, this configuration being rendered self-locking by virtue of mutual abutment of levers 6a and 6b. Also if desired the open position of Fig. 1 may be overrun to give a self-locking configuration. In alternative embodiments, the levers 6a and 6b may be of adjustable length or the adjustability may derive from making the connection points of levers 6a and 6b and arms 5 of an eccentric nature. If desired, there need be no effective adjustability in length of the levers.
