Title: Bale sledge
IPC: A01D87/12
Filed: 1963-05-20
Abstract: 1,075,854. Bale sledges. A. W. SAUNDERS and P. G. SAUNDERS. May 20, 1964 [May 20, 1963; Jan. 3, 1964], Nos. 19930/63 and 342/64. Heading B5F. A bale sledge comprises two compartments (B1, B2), Fig. 6 (not shown), arranged side-byside, a pivoted diverter 55 for directing bales into either compartment, means for moving the diverter 55 from one position to its other position after each compartment has been filled, and means for releasing the bales when both compartments have been filled. The sledge is towed behind a baler which delivers bales through a shoot 12 to a front compartment A in double deck formation. When an upper bale operates a member 36 a gate 20 is opened and the diverter directs the bale stack into compartment (B1). This stack operates a lever 60 which moves the diverter so that the next stack is delivered to compartment (B2). The driver then pulls a rope (82), Fig. 3 (not shown), which operates a catch 73 to open pivoted doors 69, 70 at the rear of the sledge. A stack of eight bales is thus released from the sledge and the gates 69, 70 are closed behind them by means of springs (72). A stop 24 operatively linked with the gate 20 prevents a following bale passing through the gate 20 while open to let the stack of four pass through. The sledge may run on wheels or on skids 2 which are hinged at 83 for negotiating rough ground.

Title: A device for protecting transformers, switches, motors, generators, and similar electrical machines and apparatus
IPC: H02H5/00
Filed: 1928-07-09
Abstract: 293,705. Buchholz, M. July 8, 1927, [Convention date]. Transformers. -- The evolution of gases of decomposition &c., for example from transformers or switches when conditions are abnormal, causes the operation of indicating or cut-out devices. For this purpose the gases are led past an electrically heated device so as to cause a change in the rate at which heat is conducted away from the device and therefore a change in the temperature of the device.. According to the arrangement of Fig. 1, when gases ascend from a transformer tank through a tube a, the change in thermal conductivity of the medium surrounding a current-carrying resistance wire or strip c causes a change of temperature of and change of resistance of the wire. This causes a deflection of the needle e<1> of a registering instrument d, and the needle may engage a contact e<2> and operate a signalling or cut-off device. The gases may also operate directly a second contact device f. In a modification, Fig. 2, the wire c lies in a tube containing ether or the like, the expansion of which operates a contact device. The Specification as open to inspection under Sect. 91 (3) (a) comprises also a construction, Fig. 3, in which the heat of the gases causes a wire h to sag and operate a contact device. The wire h is connected to a device i in a casing k to compensate for fluctuations of normal temperature. A modification of the Fig. 1 device is also described in which a second wire c is arranged in a Wheatstone Bridge circuit with the first wire c to compensate for fluctuations of normal temperature. This subject-matter does not appear in the Specification as accepted. Specification 241,228 is referred to.

Title: System for regulating the operating behaviour of an internal combustion engine
IPC: F02D21/08
Filed: 1975-05-13
Abstract: 1512213 Automatic control of IC engines  ROBERT BOSCH GmbH 13 May 1975 [19 Oct 1974] 19993/75 Heading G3R  The fuel/air ratio and/or the rate of feedback of exhaust gas in an I.C. engine is controlled in response to an electrical measurement of fluctuations in an operating parameter of the engine, the measurement beingmade by a pick-up 17 connected to an alternating voltage amplifier 21 whose output is compared at 25 with a desired value. The desired value is generated at 26, and may be varied in response to the absolute value of the parameter measured by the pick-up and/or the induction pipe pressure and speed. As shown the parameter is cylinder pressure, measured at 17 and amplified at 19, but it may alternatively be peak voltage at a sparking plug, integrated ion current or flame propagation time (measured as the time between threshold values of the voltage at the sparking plug and ion current at a probe spaced from the plug). In all cases the measurement is switched at engine speed by a transister 20 and pulse generator 28 to a capacitor 40 connected to an operational amplifier 22 whose output thus represents changes in the measured parameter between successive cycles. It is explained that these are a function of combustion mixture and the desired value may be chosen so that the fluctuations are high, due to a lean mixture. The comparator 25 switches a bi-stable circuit 32 when the measured fluctuations exceed the reference; the bi-stable then resets an integrator circuit 34 which otherwise integrates a constant voltage so as to progressively weaken the mixture.

Abstract: 881,120. Valves. CATERPILLAR TRACTOR CO. June 26, 1958 [April 25, 1958], No. 20503/58. Class 135. Control means e.g. for tractor steering clutches comprises two valves spools 14, 14a connected for reciprocation to independent control levers by spring-loaded telescopic control rods each having a reaction piston 47, and passages between the spool bores such that on actuation of one spool fluid flows through the bore of the other without respect to its position. An hydraulic pump supplies liquid to an inlet 37 where in the neutral position of the valve it passes through passage 41 to recesses 21, 19 and an exhaust outlet 42 for lubrication purposes and through a passage 39 communicating with recess 22. When valve 14 is moved to the left collar 18 allows pressure fluid to flow through recess 23 and outlet 44 to a clutch piston. Pressure liquid also enters a cylinder in the end of the valve spool through a radial bore in the collar 18, which cylinder is engaged by a piston 47 attached to the valve casing and together with a loading spring 34 tends to close the valve spool against the spring loading of the telescopic control rod to maintain the pressure constant in the outlet 44, any relief flow passing to the left of collar 18 into chamber 56 and exhausting at 57. Valve 14a operates in a similar manner and to reduce the sensitivity of operation the end collars and valve spools are formed with arcuate grooves 54.

Abstract: 1,182,494. Electric coils. SOC. INDUSTRIELLE DE LIAISONS ELECTRIQUES. 4 May, 1967 [4 May, 1966], No. 20755/67. Heading H1P. Electric coils are made by winding a cable on to a former having end flanges, winding a layer of fabric on to each layer of cable, the fabric not having been treated with a thermosetting material and impregnating the coil under vacuum with a thermosetting material. The impregnation may take place with the windings on the former or the former may be dismantled, the coil placed in a container and then impregnated. In the first technique, a casing is fitted over the flanges to give a vacuum-tight chamber which is evacuated through one orifice and the thermosetting material drawn in through a number of orifices. The fabric may be made of synthetic, natural or glass fibre. If the coil is used in a high voltage network, then its outer surface must be covered with fabric layers of high mechanical strength. In the first impregnation technique, this may be achieved by covering the impregnated coil with the fabric layers and impregnating a second time. In the second technique, the outer fabric cover is provided on the coil after removal of the former but before impregnation.
