Title: Device for raising the surface temperature of a body for example of the skin
IPC: A61N1/40
Filed: 1975-06-17
Abstract: 1513264 High frequency heating L'OREAL 17 June 1975 [18 June 1974] 25789/75 Heading H5H A device for heating a surface e.g. human skin, comprises a resonator having an electromagnetically closed envelope 1 containing an electromagnetic coil 8 for emitting electromagnetic radiation into envelope I and an application component coupled to the resonator and located externally of the envelope I for applying energy to said surface. As shown, the application component comprises a capacitor having interdigitated electrodes 26 mounted on an insulating plate 18 at one end of the envelope 1. Within the envelope is an NPN transistor 2 the base 3 of which is connected firstly to the earthed envelope via an oscillating circuit comprising a coil 4 and a condenser 5, and secondly to the collector 7 via a resistor 6. The emitter 9 is connected direct to the envelope 1. The collector 7 is also connected to a D.C. supply via the coil 8. The capcitor electrodes 26 are connected to a coil 10 which is inductively coupled to coils 4, 8. This arrangement ensures that the cavity is brought to resonance only when the capacitor electrodes are in contact with human skin. In a modification, (Fig. 2, not shown), the application component is an antenna which is coupled to the envelope cavity by being connected directly to the earthed envelope at one end and to the collector of the transistor via a capacitor at the other end. The parameters of the coils etc are chosen to ensure that the frequency generated corresponds to the resonance frequency of the envelope and the value of the capacitor is such that unless the antenna is placed against the skin little energy will be radiated by antenna. In Fig. 6 (not shown) the power application component comprises a spike formed at one end of a coil connected to the base of the transistor in the envelope. The coil is inductively coupled to a coil in the envelope which connects the collector to a D.C. source. In Fig. 7 (not shown) low power A.C. is fed to a power amplifying transistor in the envelope. The application component is an antenna coupled to a coil in the envelope by a blocking capacitor so that energy is radiated only when the skin contacts the antenna.

Title: A process and apparatus for melting polyamide shreds
IPC: D01D1/04
Filed: 1957-08-15
Abstract: <PICT:0813527/IV (a)/1> In melting polyamide shreds by feeding them to a melting surface and withdrawing the melt at a speed approximately equal to the melting speed, the shreds are flushed in the direction of their supply with a protective gas and the dripping melt is also swept by a stream of protective gas, the gas discharging through a plurality of openings in the vicinity of the melting position. The shreds may be of polycaprolactam and may have a water content of up to 10 per cent by weight.  The protective gas may be nitrogen and may be held in the system at a pressure not more than 1 mm. mercury above atmospheric pressure.  The discharge openings may be symmetrically arranged and may be sealed by a liquid, the level of which can be adjusted.  As shown, down tube 1 is fed with shreds, which fall into melting chamber 2, travel over dome 3 and fall on the radially arranged melting bars 4.  Melt drips into sump 5, in which the melt level is controlled by contact pin 6, and is extracted therefrom by pump 7.  Protective gas is supplied through the mass of shreds in the direction of arrows b (i.e. co-currently).  Gas also enters the melting chamber under the melting surface through pipe 9, and both streams of gas leave via the discharge openings 8 and pipes 10, which are sealed by a liquid of adjustable level in the vessels 11.  The pressure of gas in the melting chamber is controlled by the valves 12.  The rapid discharge of gas carrying with it water vapour, cyclic polymers and cracking products, gives a melt of constant viscosity and improved spinning performance.

Patent GB-338236-A (GB)
Title: Improvements in or relating to governing means for steam turbines or other engines
IPC: F01D17/26
Filed: 1929-08-26
Abstract: 338,236. Baumann, K., Jolley, J. E., and Associated Electrical Industries, Ltd. Aug. 26, 1929. Centrifugal governors; fluid relays.- In a means for governing a steam turbine or other engine, a centrifugal governor operates in conjunction with a fluid relay to operate the throttle valve in such a manner that movement off the valve is proportional to the position of the governor spindle and hunting is eliminated. Fig. 1 shows the pilot valve 9 attached to the governor spindle 10 and operating in a sliding ported sleeve 12. The pilot valve controls the flow of pressure fluid from a pump 34 to two pressure relay devices which comprise spring controlled pistons 1 and 1<a> operating in ported sleeves 3 and 3<a> which in turn are contained in ported cylinders. The ported sleeve 3 is provided with a piston 5 and controlled by the spring 4 and also conected to a pivoted link 8 which is also attached to the ported sleeve 12 of the pilot valve. The sleeve 3<a> is attached to a pivoted lever 20, to which is also attached the throttle valve 19 and the power cylinder 24 for operating same. The operation is as follows :-Upon a decrease of speed, the pilot valve 9 falls and permits pressure fluid to flow to chambers 22 and 23. The piston 1 rises against its spring control and permits a flow of pressure fluid from pipe 35 through ports 3<b> to the underside of the piston 5. The sleeve 3b then rises and following the movement of piston 1 again tends to close the ports 3<b> and moves the sleeve 12 in a direction to close the ports 12<a>, equilibrium being reached when the movement of the piston 1 is proportionally the same as that of the pilot valve. A similar action takes place in the second relay, the piston 1<a> allowing the flow of fluid to the power cylinder and the movement of the power piston causing the sleeve 3<a> to follow up and close the ports. For an increase in speed the reverse action takes place wherein the ports communicate with the escape drains 25, 25<a>. The speed at which the governor operates may be adjusted by moving the pivot 11, so adjusting the mean position of the sleeve 12. Modifications are described in which the pilot valve may be connected to an intermediate point in the link between the governor spindle and the first relay sleeve, and in which the ported sleeve 3<a> is replaced by a separate pilot valve.

Title: Improvements in or relating to machine tools
IPC: B23Q1/00
Filed: 1956-08-27
Abstract: 808,009. Milling-machines. GIDDINGS & LEWIS MACHINE TOOL CO. Aug. 27, 1956 (Sept. 2, 1955], No. 26143/56. Class 83 (3). [Also in Group XXX] A milling-machine comprises a trolley 50 on a track 38 adjustably mounted above the level of the path of movement of a headstock assembly 32, and means 48 on the trolley for resiliently supporting the headstock. Two headstocks 32, 33 slide on a cross-rail 28 adjustable vertically on columns 26, which also carry vertically adjustable heads 34, 35 for milling the sides of workpieces on a table 22. The headstocks 32, 33 are supported by hydraulic means 48 on the trolleys 50 running on the beam 38 which are suspended by chains 40, 41 attached to hydraulic means 42, 43. The side-heads 34, 35 are supported by chains 56 attached to hydraulic means 54. Each hydraulic means 48 comprises a piston 72 held by fluid pressure in an intermediate position in its cylinder, which rests on an annular bearing on the trolley. The pressure is supplied to the piston 72 by a pump 84, having a low-volume, high-pressure, and a high-volume, low-pressure side, at a pressure determined by a relief valve 87 and sufficient to take the weight of the head-stock, and part of the weight of the cross-rail. The exact position of each piston 72 is determined by an adjustable stop, on a projection 166 of the cross-rail, co-operating with a valve 146. The valve 146 is actuated whenever the cross-rail 28 is moved by its feed screws, and causes fluid to be supplied to the hydraulic means 42, 43, so that the beam 38 follows the cross-rail. The highvolume, low-pressure side is normally connected to the sump 97 through an unloading valve 110. It is brought into operation by actuating a solenoid 112 which moves a valve 114 to depress the valve 110, so that the lowpressure output of the pump by-passes a checkvalve 124 and is connected to the main pressure conduit 94. The solenoid 112 is actuated whenever a switch is operated to move the cross-rail up or down at a rapid traverse rate. When the cross-rail is moved rapidly upwards, the feedscrews momentarily assume the weight of the head-stocks. Electrical, hydraulic and coolant cables are carried within the beam 38 and are tensioned over pulleys by means 192, 194, 198, such as are described in Specification 734,779. The cables supply power to the suspension means and also to the head-stocks 32, 33, to which they are guided by conduits 190.
