Abstract: CHIP TO BOARD CONNECTION                Abstract of the Disclosure A configuration is disclosed for attaching leads (15) from several chips (1a-1d) to bus (5a) lines (9a-9m) on a printed circuit board (6).  The bus (5a) includes pads 13, each directed toward one of pads (3) on the chip to be connected by arched wires (15).  Lines (9a-9l) connect to each end of the board pads (13) and extend generally parallel to the chips (1a-1d) past the sections containing the pads (3).  Lines (9a-9l) are displaced alternately toward and away from the chips (1a-1d) at sections containing pads (13) directed toward the chips (1a-1d) or having a part (17) taking a corresponding direction.  The pads (13) alternate on opposite sides of each chip (1) to minimize the length of the leads (15) and to allow a central chip pad (3V) for carrying operating voltage (or ground) to connect to the outermost line (9m).  This reduces the board space used for a bus (5a) and minimizes the length of wires (15) connecting chips (1a-1d) to a bus (5a).

Abstract: ABSTRACT   In a wet shaving operation it is important to have the skin sur-face smooth and the hairs lifted up from the wrinkles to suit the blade(s).          This inventive device does it automatically. It is adapted to a conventional razor system between the cart-ridge and the handle and constantly delivers the most favorably conditi-oned skin surface to the blade(s) resulting in a high quality of shave, thereby reducing the possibility of irritation and skin damage.          Said shaving implement is a razor adaptor, features a pair of parallel arms with pivotal mounting means for connection between the de-vice and a razor blade assembly; a center portion  - as parallel continu-ation of said arms -  and sharing plurality of pairs of openings for recei-ving pivotal mounting connection from a handle and for selecting a prefer-red range of pressure distribution from said handle between the cartridge and a skin stretching bar fixed perpendicularly to the free ends of said center portion to constantly stretch and shape the skin ahead of said cart-ridge to suit the blade(s) following said bar in a parallel position during shaving; and finally a T shaped brace connected to the  base  parts of said arms and to said stretching bar to strengthen the structure of the device and to meet the spring finger at the center on the connecting prtion of sa-id handle to keep the device in a preferred angle relative to said handle.          No razor systems up until now have had any provision for skin preparation ahead of the cartridge to suit the blade(s) by lifting up the hairs from the wrinkles.

Abstract: THIGH SUPPORT CUSHION                        ABSTRACT OF THE DISCLOSURE     This invention relates to a cushion which is intended to be used by persons under their upper thighs while they are lying down or sleeping in supine position.  The primary object of this invention is to change the position of the pelvis of a person lying in a supine po-sition so that the lumbar spine flattens and the mechanical stresses and symptoms of lower back pain are eliminated.  This is accomplished by shifting the central body supporting surface from the buttocks to the upper thighs through the use of the thigh support cushion.  Con-sequently, the knees slightly flex, the pelvis rotates in a direction resulting in a decreased lumbo-sacral angle and the lower back flattens as a result of its own weight.  This invention will be useful in the treatment of many persons who suffer from lower back pain and will also be useful to other persons who are interested in the prevention of back problems.

Abstract: FOLDABLE PACKER HARROW IMPLEMENT            Abstract of the Invention An agricultural implement useful to pre-pare the ground before or after a seeding operation includes a number of soil packer units which are directly coupled to transversely extending tool bars or  frame  members  ahead  of respective,  trailing harrow sections.  The packer units are connected to the frame members by relatively short links for free up and down shifting movement during advancement of the implement across the field in substantial inde-pendence of vertical movement of the harrow sec-tions.  The frame members are pivotal about a paral-lel, horizontal axis to raise the harrow sections and the packer units to an upright orientation for transport, at which time a portion of the links supporting the packer units comes into firm, resting contact with a stop for precluding further movement of the packer units.   The relatively heavy packer units are located in proximal relation to the axis of pivotal movement of the frame members, to thereby reduce stresses imposed on the structural components of the implement and reduce the size and cost of the hydraulic piston and cylinder assembly for raising or lowering the harrow sections and packer units.          In use,  the trailing harrow sections smooth the compacted ground and function to reduce water and wind erosion,  enhance soil moisture retention and leave weeds on top of the ground to prevent further growth of the same.
