Abstract: Piston rods of three linear hydraulic motors are connected at their outer ends to two spaced apart transverse frame members. A cylinder housing is driven back and forth along each pair of piston rods. Three transverse drive beams are provided. Each drive beam is directly connected to an associated one of the cylinder housings. Three sets of floor slat members are provided. Each set is connected to azn associated one of the transverse drive beams. The linear hydraulic motors are operated for moving the floor slat members in one direction, for advancing a load, and for retracting them in an opposite direction. Each cylinder housing has four fluid chambers. First and third chambers are interconnected and the second and fourth chambers are interconnected. This arrangement provides adequate force producing area with a relatively small diameter cylinder housing. Fluid passageways are formed in the piston rods. Transfer valves are incorporated in end portions of some of the linear hydraulic motors. Each transfer valve includes an actuator rod which extends through the passageway in its piston rod. U-shaped tubes are clamped onto the outer end portions of the piston rods by means of clamp plates and interconnecting nut and bolt assemblies.

Abstract: The folding box is made from a single-piece blank, the blank being provided with impressed folding lines in the end and side walls which lines adjoin a central base area. In the production of complex packages, e.g. for chocolates or the like, a folding box is firstly produced without a projecting edge. A piece of cardboard, possibly provided with a padded insert, is bonded to said folding box. In this case, if the piece of cardboard is larger, a projecting edge results in relation to the base area of the folding box, which gives a visually attractive impression. However, the manufacturing costs are relatively high in respect of the large requirement of material and the large number of production steps required. In the new folding box, the bonding of a piece of cardboard, provided with a padded insert, is avoided due to the special type of folding. The new folding box can be manufactured automatically and requires only a small transport space when being transported from the manufacturer's to the user. <IMAGE>

Abstract: A method of selectively incrementing and decrementing the decimal values of digital filter tap coefficients is disclosed. Each tap coefficient is represented by a plurality of cannonic signed digit (CSD) encoded "nibbles". The combined CSD-encoded values of the individual nibbles bear no direct relationship to the decimal-valued tap coefficient, the range of each nibble is restricted to allow such a direction relationship. Each CSD-encoded value is adjusted by incrementing, decrementing or placement at an endpoint of its range and direction reversed, whereby the resulting decimal value will be incremented or decremented. The sign and direction of movement within the range of each nibble is readily ascertained by reference to a set of simple rules.

Abstract: A new method and apparatus are provided for sensing refrigerant temperatures in refrigerator systems, and for the control of refrigerant loading in a plurality of refrigerator evaporator circuit coils (34a,34b) connected in parallel. Such evaporator coils are supplied with refrigerant through a thermostatically controlled flow control valve (30), which is controlled by a sensor (50) to restrict the flow of the liquid refrigerant and ensure a predetermined amount of superheat. The usual minimum superheat is about 5.5 DEG C (10 DEG F) and it is often found that the evaporator coil clearly is underloaded, and in the case of a multi circuit coil evaporator, that many of the circuit coils are underloaded. To avoid this the refrigerant is rendered thoroughly turbulent and mixed, and in the multi-coil evaporator the flows issuing from all of the circuit coils are similarly thoroughly turbulated and mixed, by a turbulating and/or mixing device (48) that intercepts the entire refrigerant flow just before the sensing of the superheat, thus ensuring that the temperature is accurately measured. In the multi-circuit coil system the device averages the temperatures of all the flows, any liquid from circuits with lower heat transfer being broken, mixed with and evaporated by superheated vapour from circuits with higher heat transfer. Different turbulator/mixer devices are described and two or more such devices may be used in flow series. The amount of superheat can now safely be reduced to about 2 DEG C (4 DEG F), the efficiency of the entire system is increased, and close matching between valve size and coil loading is no longer required.
