Title: Improvements in or relating to tractor hydraulic systems
IPC: A01B63/10
Filed: 1956-01-03
Abstract: 790,158. Tractor power-lift mechanisms. FORD MOTOR CO., Ltd. Jan. 3, 1956 [Jan. 3, 1955], No. 206/56. Class 79(1) A tractor hydraulic system of the type wherein pump output liquid is by-passed to a sump or directed to a lift cylinder 11, Fig. 1, is controlled by a valve 19 in a housing 14 and a relief valve 18 between the cylinder 11 and the sump is substantially hydraulically balanced so as to be maintained closed by spring means 27 regardless of pump pressure, but to open when the cylinder pressure rises due to an impact load on the implement. The relief valve 18 having a head 23 and body portion 24, is slidable in a bore 16 in the valve housing 14, the portion 24 having a conical nose 26 engaging a seat 22 at the junction of the bore 16 and a reduced bore 21. An axial passageway 32 and a cross port 31 are provided in the valve 18, the passageway 32 having a valve seat 33, against which is urged a ball valve 34 by a spring 36. The control valve 19 is slidable in another bore 17 in the housing 14 and has lands 43, 44 co-operating with passageways 46 and 39. In the implement lifting position of the control valve shown in the drawing the passageway 46 is closed by the land 43 whilst the passageway 39 to the sump is closed by the land 44. The pump, constantly operated by the tractor, supplies liquid through a passageway 37 to the bore 16, from whence it passes through the port 31 and left hand side of the passageway 32 to open the ball valve 34 and thus pass through the bore 21 and a pasageway 38 to the lift cylinder 11. Liquid also passes through the passageway 32 to the right hand side of the valve 18, the force on that side of the valve being substantially balanced by the forces on the annular face between the head 23 and body 24, and the nose 26 (since the valve 34 is open). When the control valve is moved so as to open the passageway 46 as well as the passageway 39 the implement is lowered since the liquid in the cylinder is discharged through the passageway 38, bore 21 and passageway 46 to the bore 17 and the sump, the pump output being bypassed to the sump. When the valve 19 is positioned so as to close the passageway 46 but open the passageway 39 the pump output is still by-passed to the sump, but impact loads on the implement cause the valve 18 to open against its spring 27, the valve 34 then being seated, and pass liquid from the cylinder to the sump.

Title: Improvements in the process of neutralising acid or alkaline constituents in a gas
IPC: G01N21/80
Filed: 1932-01-08
Abstract: The neutralization of acid or alkaline constituents in a gas is controlled by treating the gas after the neutralization process so as to obtain a liquid which contains any residual portion of acid or alkali present in the gas, adding an indicator to the liquid, and causing it to traverse the path of a beam of suitably coloured light which falls upon a photo-sensitive device adapted to control the addition of the neutralizing-agent.  The liquid may be obtained by cooling, effecting condensation of moisture present in the gas.  The neutralizing-agent is preferably administered by a continuous fixed supply insufficient to effect complete neutralization and a further variable supply controlled by the photo-sensitive device.  The Provisional Specification describes also the application of the process to the control of unspecified reactions other than the neutralization of gases.

Patent HK-59294-A (HK)
Title: Wire bonding
Inventor: NAKAJIMA MAKOTO
IPC: B23K20/00
Filed: 1994-06-23
Abstract: In ball bonding, a ball (112) is formed on the end of a wire (105) by an electric discharge between the wire (105) and a discharge electrode (116). The ball (112) is subsequently pressed onto a pad of a semiconductor pellet and bonded thereto by press bonding under heat with the application of ultrasonic vibrations. However, the pressing of the ball onto the pad may damage the pellet if the ball (112) is too hard. Therefore, a reducing gas (121) is supplied to the environs of the ball (112) during its formation, the gas being supplied at a temperature preferably between 100 DEG C and 200 DEG C. This shows the cooling of the ball (112) resulting in a finer cyrstal structure, and a lower hardness. Hence the occurrence of cracking of the pellet is reduced.

Title: Method of,and apparatus for damping of stepper motor using non-active windings
Inventor: WHITE JAMES NORMAN JACKSON
IPC: H02P8/00
Filed: 1986-09-25
Abstract: In a disk drive system which uses as stepper motor, overshooting of the desired final position is reduced by short-circuiting the windings of the stepper motor which normally remain open-circuit or are switched off. This short-circuiting provides a current path for any EMF induced in the unused windings. This effect is achieved by connecting a pair of transistors in parallel with each other and with each respective winding. The transistors are connected in opposite polarity to provide a short-circuit regardless of the polarity of the EMF across the windings. The transistors are connected to a microprocessor which is programmed such that the windings are selectively short circuited and the short circuits are applied at a predetermined time with regard to the step so that 'damping' is optimized. The microprocessor may be programmed to switch the transistors on and off as desired giving flexible timing to suit different conditions. One or more stepper motor steps may be treated in this manner.
