Abstract: Facing slabs can be suspended on transverse struts or the like by means of shackles attached to their rear side. In the process, the shackles, which can be produced from angled flat steel, have to be securely fastened to the rear side of the facing slab. A secure fastening of the shackles to thin-walled facing slabs is achieved by using a fastening element which possesses an expanding member. The expanding member engages in a blind bore provided on the rear side of the facing slab and is clamped therein. The shackle is secured by means of a retaining cap engaging over the expanding member. <IMAGE>

Abstract: A diplexer (10) for communicating signals in two different frequency bands with separate polarizations in each band may, for example, concurrently separate low frequency received signals of orthogonal polarizations from high frequency transmitted signals, also of orthogonal polarizations. To this end a common square waveguide (24) leads to serially disposed, axially displaced, orthogonal mode transitions (26, 42) at which branches (28, 43) are made to closely coupled lowpass filters (30, 44) that communicate with separate ports (18, 19) for low frequency signal bands. A smaller square waveguide (57) coupled to the second of the orthogonal mode transitions communicates with another orthogonal mode transition (58) at which axially displaced branches (56, 60) communicate with other ports (16, 17) for high frequency signal bands.

Abstract: In a control system for a spark advance engine (10), a basic spark advance value is calculated from values stored in a memory (35). An adjustment value is calculated in an adjustment device (43) and a perturbation value is set by a perturbation generator (46). The basic, adjustment and perturbation values are summed and supplied to a dwell control device (17). 
     The sum of the adjustment and perturbation value together with a value indicative of engine torque are supplied as inputs to a parameter estimator (40). This estimator (40) uses these two input values to estimate two parameters which together define the relationship between spark advance angle and torque. The two estimated parameter values are supplied to the adjustment device (43), which uses them to calculate the adjustment value using a predetermined rule. Thus, the spark advance angle is quickly adjusted to an optimum value.

Abstract: An improved integrated circuit die (45) with multiple circuits on the same substrate of semiconductor material is formed with circuit elements of the multiple circuits grouped respectively into at least first and second circuit areas or sections (46, 48) of the die. The first and second circuit sections (46, 48) of the die are separated and spaced from each other by a moat or separating boundary line (50). The separating boundary line is formed using appropriate mask lines on the fabrication masks. The separating boundary line (50) is composed of the substrate semiconductor material (60) between the circuit sections (46, 48). The separating boundary line (50) is formed without implanting buried collector layers (62, 64) or channel stop regions (65, 66) in the substrate semiconductor material (60) of the boundary line (50). Relatively high resistive substrate isolation of the circuit sections (46, 48) of the die reduces feed through coupling of AC signals between circuit elements of the respective circuit sections. Separate substrate taps (52, 54) are provided for each circuit section (46, 48) of the die (45) and separate substrate tap leads are provided to each circuit section.

Abstract: A seat insert insertable within the existing seat of a vehicle for maintaining a crew member of the vehicle in a forward posture during high G acceleration. An elongated head support member is provided for supporting the crew member's head during a forward leaning posture. A back plate assembly including at least one back plate is connected to the head support member for supporting the spine in its natural curvature. Means being connected to the back plate assembly are provided for pivoting the back plate assembly forward relative to the seat of the vehicle. Means are provided for transfering any G-induced weight from the spine to the back plate assembly and ultimately to the existing seat of the vehicle. The head support member is restrained in such a manner so as to maintain the crew member's head in an "eyes up" attitude during a forward lean. The seat insert reduces the risk of spinal injury by off-loading the pilot's spine and supporting the spine in its natural curvature, thereby preventing harmful bending of the spine and non-uniform load distribution across individual vertebrae interfaces.

Abstract: 2.1 In a communication exchange with operator positions, where queuing memories are provided to hold calls which cannot be handled immediately by the operator positions, an additional answering facility is to be provided so that calls can be accepted even when the queuing memories cannot hold any more calls. 2.2 A rerouting device is provided which is activated when a queuing memory reaches a predetermined full state and diverts the calls to a call answering device. An announcement device and speech memory are located there, in which messages input by callers can be stored. An additional identification memory is allocated to the call answering device, in which data relating to received incoming connections can be stored. These are used for designated interrogation of the speech memory and are read out so that they can be displayed at the operator position. 2.3 When a large number of calls needs to be handled in communication exchanges, in particular PBX telephone systems and multi-station broker's systems, the method offers the advantage that few calls are lost, since the call answering device becomes active in good time. This results in short-term relief of the operator positions. <IMAGE>
