Title: Antistatic coating compositions
Inventor: GRAHAM MALCOLM JAMES
IPC: C08J7/044
Filed: 1985-06-26
Abstract: Antistatic coating compositions for plastics substrates, more particularly but not exclusively for synthetic paper substrates, comprise an aqueous system containing a polymeric binder, a pigment and an antistatic agent. The binder contains carboxyl groups, and the binder: pigment dry weight ratio is in the range 15:100 to 50:100. The antistatic agent is a water soluble ionic compound (e.g. a sodium polyphosphate) present in a dry weight: pigment ratio of from 0.4:100 to 2.5:100. The composition also contains an agent which reacts with carboxyl groups of the binder on drying so as to insolubilise the binder (e.g. ammonium zirconium carbonate).

Title: Apparatus and method for supporting and working on sheet material
Inventor: GERBER HEINZ JOSEPH
IPC: B26F1/38
Filed: 1985-11-27
Abstract: A bed 110 for supporting sheet material 26 to be cut or otherwise worked on is made of a densely packed array of relatively short, stiff bristles 116 with pointed upper ends which penetrate the sheet material to inhibit it from moving laterally relative to the bed. A roller may be used to impale the sheet 26 on the bristles and vacuum may be used in the space containing the bristles to aid in holding the sheet material to the bed and to normalize the holding effect of the bristles with respect to different sheet materials. Pressurized air may also be used in the bristle space to aid in removing cut sheet material from the bed and the bristles are shaped to facilitate such removal. The cutter means may comprise a disc 200 associated with a pressure foot 202 and a reciprocable elongated blade (226, Figure 15). <IMAGE>

Title: Pressure reducing valve
Inventor: BRAKE ARTHUR LEIGHTON
IPC: G05D16/10
Filed: 1985-12-13
Abstract: A pressure-reducing valve assembly comprises a piston (58) reciprocatable within a bore (52), and having a pressure-regulating valve (94, 128, 108) located between a chamber (92) within the piston and an outlet chamber (96). The valve closes as the pressure of outlet 100 reaches a desired value. The inlet (90) to the chamber (92) is arranged so that, when the valve is closed, fluctuations in inlet pressure produce no resultant axial force on the piston (58), and so that, when the valve is open, upward fluctuations in the inlet pressure tend to act to close the valve. <IMAGE>

Title: Tool mounting apparatus
Inventor: NARUSHIMA HIROSHI
IPC: B23B31/26
Filed: 1988-11-24
Abstract: To avoid unbalanced rotation and vibration of a spindle 5 mounting a tool 18 especially when operated at high speeds, a sealed piston/cylinder arrangement 23, 19 is mounted inside the spindle 5. The cylinder 19 is filled with an elastic fluid 24 e.g. silicon liquid which can be compressed. The piston 23 is attached to one end of a push rod 22 which carries a collet 27 at its other end, engaging a tool holder 18 via a pull stud 29 when in a first position and releasing the tool holder (18) when pushed to a second position by a piston rod 30 acting on push rod 22. In this second position the fluid 24 is compressed, and when the piston rod 30 is removed, the collet 27 returns to its first position due to energy stored by the elastic fluid 24 due to its compression.

Title: Control circuit for electric discharge machining
Inventor: GURWICZ DAVID
IPC: B23H1/02
Filed: 1989-05-25
Abstract: The circuit has an inductive circuit including an inductor (22) connected to a DC source (10) through regulating means (24) arranged to maintain a constant current in the inductive circuit. A switching device, which may be a MosFet (18) is connected to the inductive circuit and to the gap (20) so that when the device is conducting, current is diverted from the inductive circuit to the spark gap. The frequency and mark-space ratio of switching of the switching device (18) is controlled to control the machining process. The circuit includes elements to establish a predetermined voltage across the switching device (18) and spark gap (20). These elements comprise a capacitor (34) connected in a unidirectional current path in parallel with the switching device (18) and spark gap (20), a second switching device (40) connected in series with an inductor (38) across the capacitor, and a comparator (42) arranged to switch on the second switching device when the voltage across the capacitor exceeds a predetermined value (VREF). A diode (46) is connected between the inductor (38) and the DC source (10) so that when the second switching device (40) is non-conducting, excess energy from the capacitor (34) and inductor (38) is returned to the source. In an alternative embodiment current is diverted to the spark gap (220, Fig 3) when switching device (318 Fig 3) is non-conducting. The circuit enables both the discharge initiating voltage and the machining current to be accurately defined, and independently variable. <IMAGE>
