Abstract: An apparatus for handling empty two-piece capsules includes a vertically reciprocating feeder which extracts capsules from a hopper and forms randomly ordered linear arrays. A horizontal row of capsules are fed by the feeder to key-shaped slots in a block below the feeder. A blade reciprocally positioned adjacent the wider portion of the key-shaped slots moves into the slot at about the middle of the capsule to turn the capsules so as to be partly positioned within the narrower portion of the key-shaped slot. Each capsule is then ejected by projectable pins into a channel where the capsules are pneumatically accelerated into a pair of mated receiving rings which separate the two halves of the capsule.

Abstract: An improved electronic particle counter is described in which the electrodes (152,154) and at least part of the signal processing circuitry (160) are integrally formed on the pane (132) in which the orifice (130) is located. The pane (132) is formed from a wafer of sapphire of the grade customarily used in the manufacture of silicon-on-sapphire integrated circuits. A silicon layer (162) is first formed epitaxially on one side of the wafer and integrated circuits (160) are then formed in the silicon layer (162) using conventional photo­lithographic techniques. Illustratively, the integrated circuits (160) provide the same particle counting and particle sizing functions that are available in separate packages with state-of-the-art particle counters. An electrode (152) is formed on the same side of the wafer as the integrated circuit (160) by converting some of the epitaxial silicon to a conductive polysilicon or by depositing a metallic layer; and the electrode (152) is connected to the signal input lead of the integrated circuit. A second electrode (154) is then formed on the opposite surface of the wafer by deposition of a metallic layer. An orifice (130) is formed in each pane (132) in the sapphire by etching or drilling. Finally the wafer is diced so as to separate the individual panes (132).

Abstract: 2.1. In refuse collection vehicles, in which the filled and removed refuse collection container for intermediate storage, e.g. for a recycling, performs a transporting and storing function for the refuse, considerable space on the chassis is wasted because the refuse is filled into the compression device and is conveyed from this into the refuse collection container. The new refuse collection vehicle is intended to combine a simple construction with an optimum refuse-holding capacity. 2.2. For this purpose, the path of the pusher element (16) extends through the opening (8, 8') into the refuse collection container (5, 5'), so that the compression element in the refuse collection container can be moved to and fro, the refuse-filling opening (7) is furthermore arranged on the refuse collection container, so that the refuse can be compressed solely in the refuse collection container, and, finally, the opening (8, 8') is closed by the compression element (V) when the refuse collection container is situated on the chassis. This gives a simple construction in combination with optimum holding capacity of the refuse collection container. The simple compression device requires little space behind the driver's cab when the refuse collection container is filled directly. 2.3. The refuse collection vehicle is especially suitable for an environmentally conscious refuse disposal with intermediate storage and recycling. <IMAGE>

Title: Fast summing circuit
Inventor: ISHIZUKA AKIRA
IPC: G06F7/50
Filed: 1988-06-14
Abstract: A summing circuit (20) is for summing up zeroth through n-th input data signals A(0) to A(n) to produce a sum signal S consisting of zeroth through m-th output bits s(0) to s(m) where n represents a first predetermined natural number and m represents a second predetermined natural number which is not less than the first predetermined natural number. A preprocessing circuit (22) preprocesses the zeroth through the n-th input data signals A(0) to A(n) into a preprocessed signal which is (n + 1) bits long. A logic circuit (24) carries out a logical operation on the preprocessed signal to produce the sum signal S. For example, each of the zeroth through the n-th input data signals A(0) to A(n) is given by an equation:      where a(d) represents a d-th coefficient having one of logic zero and one values, k represents a predetermined integer which is not less than zero, and A represents a common coefficient having the logic zero value. Each of the zeroth through the n-th input data signals A(0) to A(n) may be given by another equation:      where p(d)'s represent zeroth through n-th discrete integers.

Abstract: An intramedullary anchorage nail for the treatment of fractures in long tubular bones consists of a hollow body (1) of histocompatible metal and a similarly histocompatible non-metallic inner body (2a, 2b) whose material has a lower resistance to deformation than has that of the hollow body (1). The inner body (2a, 2b) lies secure against twisting in the hollow body (1). The hollow body (1) and the inner body (2a, 2b) have mutually complementary holes (12 to 15, 17, 18). So that reductions in the cross-section of the hollow body (1), which may occur when driving the hollow body (1) into the medullary cavity of a bone, do not too greatly impede the insertion of the inner body (2a, 2b), it is proposed that the inner body (2a, 2b) consist of two partial bodies (2a, 2b) whose longitudinal extent is as great as is necessary for the retention of screws introduced into their holes (14, 15, 18). <IMAGE>

Abstract: A filtering device is made by inserting into an injection mold a porous, rigid or semi-rigid filtration element that has inflow and outflow faces separated by a peripheral surface and then injecting resin into the flow channel of the mold at a pressure and temperature such that the resin does not significantly penetrate into the peripheral surface beyond its surface pores. The resin can be a thermoplastic rubber and can form the facepiece of the respirator mask. An inhalation plenum for the mask can be formed at the same time by inserting into the flow chanel of the mold a thin layer of a second resin which substantially does not melt at the pressure and temperature at which the first resin is injected. A complete respirator mask can be produced at a single station in a single insert-molding operation by inserting an exhalation valve and harness attachments together with said filtration element before injecting the first resin. Hence, the respiratory mask can be manufactured inexpensively while affording extraordinarily long service life.
