Abstract: 956,635. Moulding chipboard and like panels. E. GRETEN, [trading as BAHRE-METALLWERK KOMM.-GES.]. April 25, 1962 [April 25, 1961], No. 15749/62. Heading B5A. In the moulding of panels from discrete particles, a loose mat of particles is laid on a continuous movable conveyer and is cut into individual sections of predetermined length by cutting a narrow channel transversely of the uncompressed loose mat while concurrently tamping and compacting the particles forming the opposed walls of the channel. One embodiment of a suitable apparatus (Fig. 1) comprises a continuously moving conveyer 1 carrying cauls 4 under the mat-forming station 6. The mat of loose particles 13 is cut into sections 14 by the cutting, tamping and compacting mechanism 7 which is mounted via frame 8 on a wheeled carriage 9 for movement along the track 10 so that cutting may be performed while the conveyer is moving. Fig. 4 is a view along lines 4-4 of Fig. 1 showing the cutting saw 47 carried below a box-like housing 24 provided with rollers 25 for movement along track 32 effected by motor 38. This entire system is capable of vertical movement along screws 33 driven by motors 33a. The rotary saw 47 is supported below the housing 24 by convergent members 44 (Fig. 6) and has a suction device (not shown) to exhaust the cuttings. Means for tamping the sides of the cut channel are provided by hollow members 53 positioned slightly to the rear of the leading saw edge. Lines 59 and 60 deliver and exhaust hydraulic fluid to effect vertical reciprocation of piston 57 to actuate through rod 56 a lazy tong linkage 55 and thereby oscillate members 53 about pivots 54 at a speed rapid in comparison to the rate of movement of housing 24 transversely across mat 13. The compacting of particles along the sides of the channel may be facilitated by maintaining the compacting faces of members 53 at an elevated temperature by the introduction of a heated medium through lines 61 and, if desired, by discharging a hot fluid on to the channel sides through openings 62. This fluid medium may contain supplemental adhesive if required. In an alternative apparatus the cutting and compacting device is stationary and the mat forming station is movable. Other tamping assemblies and an electrical control system for the apparatus are also described.

Title: Method of and means for driving pins into solid material and pins suitable therefor
IPC: B25C1/16
Filed: 1955-06-03
Abstract: 780,388. Driving pins into structures by means of explosively-actuated tools. SCHULZ, W. June 3, 1955 [July 8, 1954], No. 16017/55. Classes 9(1) and 119 In driving pins with screw threaded shanks into structures by means of explosively-actuated tools, each pin before it enters the structure is caused to rotate corresponding to the hand of the screw thread at a speed so related to the pitch of the thread and the velocity of projection of the pin that the pin is effectively screwed into the structure. In one form the tool barrel 1, Fig. 2 is formed with a steep right-hand rifling 2<SP>1</SP> which may be uniform or, as shown, decreasing in pitch towards the muzzle and terminating at a point 3 short of the muzzle. The shank 4<SP>1</SP> of the pin has a right-hand screw thread of pitch corresponding to the smallest pitch of the barrel rifling. The head 5 of the pin has no thread and is covered with a softer material which presses into the barrel rifling. Alternatively a temporary head of softer material may be fitted to the pin head proper to guide it in the barrel rifling. Fig. 3 shows a pin which can be fired from a smooth bore barrel and has a head portion 7 with a standard righthand screw thread for mounting a nut when the pin has been driven home. On firing, the action of the gases has a turbine effect on the threads causing the pin to rotate in an anti-clockwise direction. The shank 8 of the pin is thus provided with a left-hand screw thread. Alternatively spiral grooves of high pitch may be specially formed in the head to create the turbine effect, or as shown in Fig. 5 oblique passages 10 may be bored through the pin heads. Temporary heads provided with grooves or passages may be secured to screwed head 7 shown in Fig. 3. The shank of the pin may be provided with a multiple thread extending to the tip of the pin and the thread may be interrupted where it is desired to fire into soft material such as wood. In a further modification the pin may be constructed for rocket propulsion, the head 13, Fig. 7 being provided with oblique passages 14 filled with propellant or constructed as a chamber containing the propellant which emerges from an opening provided with thread-like flutings 15, Fig. 8. A standard cartridge may be used to initiate the forward movement of the pin and to ignite a propelling charge carried by the pin. Alternatively the striker pin may be arranged to strike a percussion cap which in turn ignites the propelling charge or ignition by a striker may be replaced by an electrical ignition system.

Abstract: 1,009,433. Retractive switches; switches held set and freed mechanically; momentary-contact switches. R. T. HAMILTON. April 27, 1962 [Oct. 30, 1961], No. 16115/62. Divided out of 999,538. Heading H2B. [Also in Division F2] In an hydraulic braking system (Division F2)  a switch unit 21 may be provided on the lower part of the vehicle bulkhead 10 and comprises a slidable plunger 23, operated when the brake pedal is depressed, an annular contact block 26 and two electrical switch plungers 33 connected to an indicator lamp mounted on the vehicle dashboard. When the pedal is in its off position the contact block 26 is urged by a spring 25 against an end wall 39 of the body of the switch unit and in this position the two switch plungers 33 bear against the insulating ring 29 so that the lamp is not illuminated (Fig. 2). As the brake pedal is depressed it bears against the switch plunger 23 to move the latter against the action of the spring 25 together with the contact block 26 until the switch plungers 33 bear on conductive contact 32 to close the lamp circuit. This indicates to the driver that the hydraulic system is in an efficient state. Should partial failure occur the brake pedal may move on to the position wherein an insulating ring 30 is in contact with the switch plungers 23 so that the lamp circuit is closed only momentarily. If complete failure occurs, the brake pedal will be pushed down to the bulkhead so that the insulating ring 30 will move past the switch plungers 33 which will then contact an electrically conductive stop collar 27 so that the lamp is illuminated and the switch is locked in this position until the defects are rectified (Fig. 3). Instead of switch plungers 33, resilient blade contacts may be provided (Figs. 4 and 5, not shown). The switch may be integral with the brake master cylinder (Figs. 6 to 10, not shown) Specification 1,009,434 also is referred to.
