Title: Molding articles having a pile- like surface
IPC: B29C37/00
Filed: 1981-03-23
Abstract: An apparatus is described for molding articles of resinous materials, the surface of the molded article having a pile-like texture or structure, an example being a plush toy animal. The pile-like structure is composed of the material of the surface stratum of the article and is formed by the adherence of such material to the surface of the mold cavity wall in which the article is molded and by pulling the article away from the mold cavity wall while at least the surface stratum thereof is in a deformable condition such as a semimolten or plastic state resulting from the elevated temperature thereof caused either by the manner in which it is cooled or by applying heat thereto through the mold cavity wall. The entire surface of the article may be formed with short or fur-like filamentary formations or selected portions thereof may be so formed by selectively heating the mold cavity wall in a manner to maintain portions of the surface stratum of the molded material in a tacky condition such that it adheres to the surface of the mold.

Title: Digital timing system
IPC: F02P5/15
Filed: 1981-06-11
Abstract: A system suitable to set spark timing in accordance with engine speed includes a counter (14) to count clock pulses between engine speed reference pulses.

Title: Wheel cylinder for a hydraulically operated drum brake
IPC: F16D65/22
Filed: 1981-10-16
Abstract: The wheel cylinder consists of a cylinder housing 1 which is supported against one brake shoe. Mounted for axial displacement in the cylinder housing is a piston 2 which can be acted upon by the pressure of a liquid. Further mounted for axial displacement in the cylinder housing is a thrust bolt 3, one end of which is supported against the piston 2 and the other end of which is supported against the other brake shoe. In order to prevent the vibrations which occur as a result of friction when the brake shoes are applied against the brake drum, it is provided that the piston is displaceable, against the force of a compression spring element 6, in the axial direction, towards the end of the thrust bolt supported against the brake shoe. The extent of this relative axial displacement is limited by stops. <IMAGE>

Title: Antennas
IPC: H01Q5/45
Filed: 1981-11-12
Abstract: A radar antenna includes a box horn radiator 1 which is capable of simultaneously transmitting X band and S band signals. The S band signals are transmitted as a resultant of the TE01 and TE03 mode, which is generated within the box horn. Additionally, the X band frequencies are fed into an off-set input port 3, which launches the X band signal as a surface wave. By position the box horn at the focus of a reflector, azimuth pointing errors are prevented but different elevation patterns are produced. <IMAGE>

Title: Childproof closures
Inventor: SUMMERS KENNETH L
IPC: B65D50/04
Filed: 1982-04-22
Abstract: A child-resistant safety container for preventing access to the contents by small children and infants includes closure cap 23, 63 having an internally threaded side wall 29, 70 and a pair of inwardly protruding lug means 33, 34, 73. Disposed in combination With the container spout are sawtooth detent means including two series of ratchet teeth 25, 64, 65 which are spaced approximately 180 degrees apart, and which are arranged for interlocking engagement with the inwardly protruding lug means. However, one series of ratchet teeth are offset from the other series by a half ratchet tooth spacing so that the full engagement of the locking lug means with the ratchet teeth alternates from one locking lug means to the other with each angular turn equal to a half ratchet tooth. The ratchet teeth have an axial height which is such that, in order to remove the cap from the container spout, it is required that the closure cap be distorted into an elliptical shape and two turns of approximately 180 degrees each be performed. Spout 62 can be pushed into the container so that access to cap to distort the latter is prevented. <IMAGE>

Inventor: SCHLEUTER WILLIAM BRYAN
IPC: F03G7/10
Filed: 1982-05-07
Abstract: Method and system for amplifying initial electrical energy inputted into a prime mover to produce much higher levels of work output than would ordinarily be possible, by intermittently energizing an electromagnet (2) to develop strong, short-lived repelling magnetic power pulses between it and a similarly polarized permanent magnet (1); using such intermittent repelling magnetic pulses to drive a spring-loaded reciprocating piston (4); and rigging up such piston (4) to pressurize hydraulic fluid for use in a hydraulic motor (30), or to drive an engin crankshaft directly. Alternatively, the invention may be modified by using two electromagnets (Fig. 2, 1 and 2) to develop the necessary magnetic repelling pulses, or to pressurize gas instead of fluid for use as a driving medium in the prime mover.
