Title: Composition of matter and method for conversion of c3 and c4 hydrocarbons
IPC: B01J23/78
Filed: 1986-07-24
Abstract: Compositions of matter comprise oxides of silicon, aluminum and/or titanium mixed with combinations of manganese oxide and magnesium oxide; iron oxide and magnesium oxide; calcium, strontium, barium, tin and/or antimony oxides, manganese oxide and magnesium oxide; and iron oxide, manganese oxide and magnesium oxide.

Patent EP-0194087-A3 (EP)
Title: Digital electronic inclination gauge
IPC: G01C9/06
Filed: 1986-02-24
Abstract: An apparatus for sensing and measuring changes in inclination and providing a digital readout. By sensing pulse width changes rather than amplitude, the apparatus provides improved immunity to instability and environmental changes. A variable frequency scale factor oscillator (24) allows choice of readout units. Any preset angle may be selected as a zero reference. The capability is provided to hold any reading displayed for any desired period of time. An overrange indicator (26) is actuated when the linear range of the sensor (20) has been exceeded. Digital output signals derived from the sensor (20) are applied to gate an angle generator (30) which is responsive to correction factor signals to adjust the digital count in accordance with stored offset data (32). The digital signal count is incremented or decremented in accordance with a signal representing the sign of inclination, derived from the sensor pulse widths and applied to gate the angle generator (30) accordingly. The resulting digital count signal and sign signal are used to energise a display drive (34) for actuating a liquid crystal display (40).

Filed: 1987-10-29
Abstract: A radio telephone apparatus is assigned with an 
identification code beforehand and includes a parent unit (1) 
and a radio telephone set both storing this identification 
code. When the radio telephone set is put on the parent 
unit (1), a charging path through which a battery of the radio 
telephone set is charged by a charger (13) of the parent unit (1) 
and a data channel through which data is 
transmitted/received between control circuits of the parent 
unit (1) and the radio telephone set are formed. The control 
circuit (14) of the parent unit (1) transmits an identification code 
request signal to the radio telephone set in response to a 
charging start signal from the charger (13). The control 
circuit of the radio telephone set sends back the 
identification code stored therein. The parent unit (1) 
compares the received identification code with the 
identification code stored therein. If the two 
identification codes are not coincident with each other, 
the parent unit (1) controls an alarm unit (16) to generate an 
alarm.

Patent EP-0248644-A3 (EP)
IPC: G01F1/32
Filed: 1987-06-03
Abstract: A vortex shedding bluff body for generating 
vortices in a fluid flowing through a passageway 
within which the bluff body is supported. The bluff 
body extends only partially across the width of the 
passageway such that a significant proportion of the 
fluid flow occurs between the free end of the bluff 
body and the side of the passageway towards which the 
bluff body extends. A relatively short bluff body 
extending for example only one fifth of the way 
across a passageway can generate vortices the 
characteristics of which enable an accurate 
measurement of the fluid flow rate to be derived. 
This means that the introduction of a vortex shedding 
bluff body need not significantly reduce the carrying 
capacity of the pipe into which it is introduced.

Title: Circuit arrangement for the automatic adjustment of the steady current in a push-pull end stage
IPC: H03F1/32
Filed: 1988-08-06
Abstract: 2.1 The quiescent current of a push-pull output stage is automatically adjusted by providing a sensing element in each branch of the output stage. The two voltages measured across the sensing elements with respect to reference potential are input to a differential amplifier stage, the output voltage of which is compared with a reference value with the aid of a comparator. The circuit exhibits a frequency-dependence of the automatic quiescent-current regulation due to the cut-off frequency of the output transistors used. 2.2 To avoid this frequency-dependence, a phase-rotating section is connected to one input of the differential amplifier, which worsens the common-mode suppression of the differential amplifier at high frequencies. The result of this measure is that the frequency- dependent error is compensated. 2.3 Push-pull output stages with quiescent-current control. <IMAGE>

Abstract: A base region (26) is formed in a semiconductor 
structure and an emitter region (30) is disposed on a surface 
of a first portion (26″) of the base region (26), the emitter 
region having upper and side surfaces. An active base region (26″) 
is formed in the first portion of the base region (26) and an 
inactive base region (26′) is formed in a second portion of the 
base region (26). A layer (34) of insulating material is formed 
over a surface of the inactive base region (26′) and over the 
upper and side surfaces of the emitter region (30). Portions 
of such layer are selectively removed to expose the upper 
surface of the emitter region (30) and a portion of the surface 
of the inactive base region (26′), and to maintain a region (34a,34b) 
of insulating material between the exposed surface portion of the 
inactive base region (26′) and the side surface of the emitter 
region (30). Silicide contacts (36,38) are formed on the exposed 
surface portion of the inactive base region (26′) and the exposed 
upper surface of the emitter region(30), with the insulating 
material (34a,34b) region insulating such contacts from each other. 
The spacing between the base and emitter contacts (36,38) is 
defined by the width of the insulating materials region (34a). 
A collector region (32) is formed similarly at the same time and 
has a surrounding region (34c,34d) of insulating material and 
a silicide contact (40). A silicide contact (44) formed over a 
p-n junction between a p-type inactive base region (26′) and 
an n-type epitaxial layer (14) forms a Schottky diode junction (45).

Title: Improved method of making explosively bonded multi-laminar composite metal plate
IPC: B23K20/08
Filed: 1988-11-04
Abstract: A method of explosively bonding metal plates into a multi-laminar composite plate wherein the metal plates are assembled over a restraining means,eg an anvil,in overlapping spaced-apart relationship, a driver plate having a mass of at least the total mass of the plates to be bonded is disposed over the top plate of the assembly at a stand-off distance of at least half its thickness, a buffer layer of granular inert material is disposed between the driver plate and the top plate,and an explosive layer is placed on the driver plate and detonated in the direction parallel to the driver plate. The number of plates which can be bonded in a single operation can be increased by placing an explosive layer driver plate and a layer of granular inert material symmetrically on each side of an assembly of metal plates and detonating each explosive charge simultaneously. The method produces multi-laminar composite plates having improved uniformity of bond quality at the interfaces.In addition the method allows increased areas of metal plate to be bonded without producing excessive wave amplitude at the interfaces.
