IPC: B43K1/08
Filed: 1964-03-17
Abstract: 1,078,681. Making pens. I.R.C. Ltd. March 15, 1965 [March 17, 1964], No. 11280/64. Heading B3A. [Also in Division B6] The ball 12 of a ball-point pen is initially inserted into a cylindrical cavity formed in the pen tip. The ball is positioned by a stop 19, Fig. 1 (not shown), while the walls of the cavity are constricted around the ball in a conventional manner by a conical die 20. This initial operation forms a base seat 14 and a lateral seat 15 of part spherical form. A second operation is to apply a hollow cylindrical die 22, Fig. 2 (not shown) to the forward end of the nib, which die exerts an external pressure at a plane 23 located at a distance approximately one ball diameter to the rear of the ball centre. This operation enlarges the lateral ball clearance along the lateral seat 15. A third operation is to push the ball 12 outwards from the socket a distance equal approximately to one-tenth of the ball diameter. This is achieved with a pin 24, Fig. 5 (not shown), introduced from the rear through the ink feed duct 17, and results in a further enlarging of the lateral ball clearance. The finished ball-point nib is characterized in that when the ball 12 is pushed along the longitudinal axis of the pen into contact with the base seat 14, there exists a clearance between the ball surface and the lateral seat 15 Fig. 6, which in all transverse sections normal to the longitudinal axis of the pen nib forms a circular annulus of uniform width and in all longitudinal sections containing said longitudinal axis increases in width from the lower edge of the lateral seat towards its upper edge.

In the projector illustrated light from two lamps 16 (only one shown) (Fig. 2) is projected by lenses 23, 38 and mirrors 24 on to a transparency held on a glass plate 41 by spring urged rollers 45, 46 and cooled by blowers and is then projected by lens 53 and mirrors 121 on to a screen. The intensity of each lamp 16 is varied by a "Variac" (Registered Trade Mark) and a variable diaphragm 27 is provided above each mirror 24. The lenses 53 (Fig. 5) are mounted on plates 59 and attached by vertical screws 61 to a support 52 so that the lenses can be adjusted vertically. They are prevented from rotating about screws 61 by rods fixed to the plates 59 and which extend through holes in the support 52. The mirrors 121 are universally mounted on the support 52. They are each rotatably mounted on a rod 95 which is mounted on the arms of a U- shaped member 81. The mirrors are also operatively connected to the head 111 of a vertically adjustable rod 87 so that rotation of knob 115 causes the mirrors to rotate about rod 95. The U-shaped member is fixed to a plate 85 and the mirror is rotatable about the vertical axis of a nipple 87 of the plate 85. The rod 95 is mounted in elongated slots 93, 94 in the member 82, slot 93 being longer than slot 94. The end of rod 95 adjacent slot 93 is engaged by a block 97 which is adjustable vertically by screw 98 to rotate bar 95 and hence the mirror about slot 94.

Title: Electrically-controlled switching circuit
IPC: H01L45/00
Filed: 1965-03-19
Abstract: 1,099,375. Semi-conductor switching circuits. DANFOSS A/S. March 19, 1965 [March 19, 1964], No. 11828/65. Heading H3T. [Also in Division H2] In a switching circuit including two or more junctionless, non-rectifying solid state switching devices each capable, upon application of a control voltage in excess of a threshold value of switching from a high resistance to a low resistance condition, by triggering one solid state switch into conduction the others are caused to follow due to transformer coupling between them. As shown a pulse from 26 causes switch 16 to conduct so that capacitor 23 which has charged from the A.C. or D.C. supply 14 via load 15, discharges through primary 19 and induces a pulse in the secondary 20 to switch on 17 and similarly 18. The pulses from 26 may be coupled to the supply 14 to obtain the correct phase sequence for A.C. operation. The switches may be polycrystalline solid state switches the threshold voltages of which can be set by suitable selection of the mixture proportions or thickness of the switch material. In a parallel arrangement of switches (Fig. 2, not shown), first switch (3) conducts and then the voltage induced in the secondary winding (8) of the coupling transformer connected to both switches causes the other switch (4) to conduct. Resistors (5, 6) connected in series with the switches (3, 4) may be chosen so that most of the load current passes through switch (4). An inductor is also connected in series with each switch so as to protect them from mains interference. In a three-phase arrangement (Fig. 4, not shown), having delaying networks (41, 46) the switches of the second and third phases receive delayed pulses so as to make the switches conduct at intervals of 60 degrees (electrical).
