Title: A counter system
Inventor: LUNDGREN GILLIS
IPC: A47F9/02
Filed: 1983-03-22
Granted: 1986-01-30
Abstract: A counter system comprising at least one counter and a plurality of shopping carts. The counter includes a cashier's section and a conveyor band for articles and assists in defining a passage for the carts to move past the cashier's section. The counter further has a receiving section having a height from the floor slightly greater than the loading surface of the carts from the floor and the passage has a width smaller than the shopping carts so that a cart can move in the passage only when it is perpendicular to the passage and its loading surface extends below the receiving section whereby the receiving section removes any articles present on the loading surface of the cart when it passes the system.
Patent DE-3362033-D1 (DE)
Title: Body from resilient foam material, such as a buffer, a seat cushion or mattress from foam rubber or synthetic foam material
Inventor: SAVENIJE FRANCISCUS GERHARDUS
IPC: A47C27/04
Filed: 1983-09-30
Granted: 1986-03-13
Abstract: The body in resilient foam material, e.g. a buffer element, seating cushion, mattress or the like in foam rubber or foam plastics, is provided with a number of spaced incisions containing compressible springs. When the body carries no load, each spring is in relaxed condition and in non-slidable contact with one or with both side walls of the incision over its entire length whilst, under load, it is in contact with both side walls. The springs may be zig-zag wire springs in straight incisions or coil springs in cylindrical incisions so that the spaces within the springs are filled with (integral) body material. Used for foam rubber or plastic mattress, seat cushion, vibration-damping equipment support, shock adsorbing member, packing element etc. The body is easily manufactured using inexpensive low-density foam material and yet provides and maintains homogeneous resilience in use so that the presence of springs cannot be felt, e.g. in a mattress or cushion. The springs remain correctly positioned when the body is deformed or bent.

Title: Annular slot antenna
Inventor: SANFORD GARY GEORGE
IPC: H01Q13/10
Filed: 1984-01-21
Granted: 1988-09-29
Abstract: A microstrip annular antenna structure is formed by four quarter-wavelength microstrip radiator patches arranged in a quadrant formation and having outwardly directed adjacent radiating apertures which together provide a composite annular radiating slot extending about 360 DEG  of azimuth. All such radiators are fed in-phase by a single centrally located feedpoint and equal length microstrip transmission lines extending diagonally therefrom to a respective matched impedance feedpoint associated with each radiator patch structure.

Title: Rotary vaned pumps
Inventor: POSS WERNER
IPC: A22C11/08
Filed: 1984-06-27
Granted: 1989-06-08
Abstract: A rotary vaned pump has solid vanes of fixed length sliding in a boss mounted for rotation about a longitudinal axis eccentrically displaced from the longitudinal axis of the pump chamber, so as to provide respective pump compartments in the pump chamber which vary cyclically in volume and are arranged to pressurize fluid entering the pump chamber through an inlet opening and discharging from the chamber through an outlet opening. Each leading vane edge that passes over the inlet opening is formed as a shearing knife edge that shear-cuts any cuttable solid material in the entering fluid that is engaged by the edge as it enters the pump chamber through the inlet. Such solid material is thereby cut into pieces which can be handled by the pump without jamming rotation of the rotor. The leading edge of the inlet opening is also formed as a knife edge that cooperates with the vane edge to shear the solid material. The vanes slide radially in the rotor boss and their tips engage the rotor chamber cylindrical interior surface surrounding the longitudinal axis, this surface being formed as a specially calculated face cam permitting the use of the solid constant length vanes.

Abstract: 0 The ribbon (17) has an external run between the type element (25) and platen of a daisy-wheel typewriter. This run stretches between terminal members (59) which protrude from side arms (33 and 34) of the cartridge casing (18) and are fixed to the distal ends of arms (39, 41) pivotally mounted in the casing (18) at (52). The arms (39, 41) are biased downwardly by wire springs (67) to expose the typing line. Ribbon lift levers of the typewriter raise the arms simultaneously to position a selected one of three tracks on the ribbon at the level of the typing point. The terminal members (59) slide on guides (62) at the ends of the side arms (33, 34), constraining the external ribbon run to lie always within and translate within a single plane. The edges of the guides (62) are curged so that the tilt of the terminal members (59) varies as they move up and down, in such a way as to maintain the ribbon tension uniform across the width of the ribbon (17). The arms (39, 41) are flexible and have pivotal play to permit these constraints on the terminal members (59).

Abstract: The atmosphere containing hydrogen, carbon monoxide and/or nitrogen is produced by catalytic decomposition of a starting fluid. The protective gas formed is passed to a use chamber, in which a temperature suitable for treating feed material prevails. To make such a process as economical, simple and universally applicable as possible, it is proposed to pass the starting fluid over a catalyst which is in heat-conducting contact with the protective gas atmosphere of the use chamber, the starting fluid being heated before it enters the catalyst.

Title: Multi peroxide stage mechanical pulp bleaching
Inventor: TIBBLING PETTER
IPC: D21C9/10
Filed: 1986-02-12
Granted: 1989-02-09
Abstract: Bleaching of a mechanical pulp, such as chemimechanical pulp (CMP), chemithermomechanical pulp (CTMP), and the like, achieves high brightness. A lignocellulose mechanical pulp is subjected to two different peroxide (P) stages (12, 18), and a hydrosulfite (dithionite) (T) stage (20). A P-P-T sequence is preferred (although a P-T-P sequence also produces good results). Bleaching is typically accomplished in all stages at a consistency of between about 8-30%. Between the peroxide stages, the pulp is preferably pressed (19). Between a peroxide stage and a subsequent hydrosulfite stage the pulp is preferably pressed (19 min ), and the pH reduced to between about 5.5-6.0 when diluting with SO2 water (26). The P-P-T bleaching sequence results in pulp with unexpectedly high brightness, brightness levels of about 83% ISO, and greater, being possible.
