Patent EP-0185383-A3 (EP)
IPC: A61M1/00
Filed: 1985-12-20
Abstract: A bag clamping arrangement, such as an arrangement 
for automatically controlling the filling volume and overflow 
of a liquid conducted into a flexible bag which is clamped in 
the arrangement. The bag clamping arrangement is essen­
tially constituted of a rigid upwardly open receptacle of 
substantially rectangular or a relatively large upper compart­
ment, and wherein a narrow compartment which in open 
communication with the upper compartment depends down­
wardly from the bottom of the upper compartment so as to 
extend longitudinally and generally centrally across the full 
width of the receptacle. The lower compartment includes 
opposite parallel sidewalls which are down so as to form a 
reducing compartment width therebetween. Towards the 
lower end of the compartment is a plate-like clamping 
arrangement essentially constituted of a flat plate member 
which may be manually engaged through an elongate slot 
and gripping portion proximate its upper horizontal edge. 
The plate member is provided along its lower edge on both 
sides thereof with sideways projecting resilient clamping 
components which, upon being inserted into the lower 
compartment of the receptacle, are biased towards the plate 
member and are dimensioned to clampingly engage be­
tween the sides of the clamping plate and the contiguous 
sidewalls of the lower compartment. A flexible bag is 
positioned on either one side, or two bags each respectively 
on the opposite sides of the clamping plate member prior to 
insertion of the latter into the receptacle, with the lower end 
portion of the bag or bags extending between the respective 
resilient clamping component and the facing surface of the 
clamping plate member such that, upon introduction of the 
clamping plate member downwardly into the lower compart­
ment, the applicable resilient clamping component upon 
being biased towards the plate member, will clamp the lower 
bag portion against the facing surface of the clamping plate 
member, thereby ensuring the secure clamping of the bag.

Abstract: Ein asymmetrischer Thyristor mit einer n⁺pn⁻np⁺-Zonen­
folge wird beschrieben, dessen Funktionsweise nicht 
beeinträchtigt wird und insbesondere dessen Rückwärts­
sperrkennlinie nicht degradiert wird, wenn er nach 
Durchlaßbelastung und anschließender Kommutierung vor 
Ablauf seiner Freiwerdezeit durch die wieder anstei­
gende positive Spannung zündet. Diese Unempfindlichkeit 
gegen Zündvorgänge infolge Unterschreitung der Frei­
werdezeit wird erreicht durch einen flachen Anstieg der 
Dotierungskonzentration von der n⁻-Zone zur n-Zone, 
wobei die Dotierungskonzentration in der n-Zone über 
eine Strecke von mindestens 50 µm annähernd exponen­
tiell ansteigt. Um bei flachem nn⁻-Übergang den Vor­
wärtssperrstrom gering zu halten, werden Dicke und 
Dotierung der n⁻-Zone so bemessen, daß bei der höchsten 
vorgesehenen Vorwärtssperrspannung die elektrische 
Feldstärke am pn⁻-Übergang etwa 1,5 . 10⁵ V/cm beträgt, 
in der n⁻-Zone annährend linear verläuft, und am nn⁻-­
Übergang etwa ¼ des Wertes am pn⁻-Übergang beträgt. 
- Verfahren zur Herstellung dieses Thyristors werden 
beschrieben.

Title: Radio clock provided with a ferrite rod antenna
IPC: G04C9/02
Filed: 1987-04-09
Abstract: A radio clock (11), in particular one designed for use in homes, should be designed so that even under unfavourable radio reception conditions or random conditions according to the position of installation, it will ensure decoding of the received time data. For this purpose it is proposed that the radio receiver be fed from a ferrite rod main aerial (21), the original directional characteristic of which is damped towards an all-round receiving characteristic by inductive coupling of a balancing aerial (22) also having a tuned aerial circuit, but which is not connected to the radio receiver (14). If, on the other hand, (instead of this or additionally) provision is made for switching between main aerials (21) with different space orientation and each having its own tuned aerial circuit (17), the aerial circuits (17) of the (main) aerial (21) temporarily not connected to the radio receiver (14) are short-circuited or opened in order to prevent oscillatory effects. <IMAGE>

Title: Brake pressure control valve
IPC: B60T13/14
Filed: 1987-05-07
Abstract: The invention relates to a brake pressure control valve which contains a brake pressure build-up valve. The brake pressure build-up valve comprises a pressure compensated seat valve. A second valve member, a rod between the two valve members and a tubular compensating piston are provided to produce pressure compensation at the valve member. The compensating piston which encloses the rod is displaceable relative to the latter and comprises a second valve seat at its end directed towards the second valve member. A sealing ring also encloses the tubular compensating piston. When the first valve member is raised from its valve seat, the second valve member can precede the tubular compensating piston, thereby preventing friction forces between this compensating piston and its sealing ring from being disruptive during opening of the seat valve. Also provided is a valve slide which only uncovers flow bores when the seat valve is opened for the purpose of increasing brake pressure. Brake pressures can be smoothly controlled by means of the control slide.

Patent EP-0270192-A3 (EP)
IPC: H03H19/00
Filed: 1987-12-02
Abstract: A filter comprises an amplifier circuit arrangement having a 
signal input (1) and a signal output (8) and a coupling (36) 
between a point (37) on a signal path (39) to the signal input 
and a point (38) on a signal path from the signal output. The 
amplifier circuit arrangement comprises an inverting amplifier 
(6) to the input (5) of which the signal an input (1) is 
connected via a series impedance (7), e.g. a resistor. A 
feedback impedance (9), e.g. a capacitor, connects the amplifier 
output (8) to its input (5) so that this input constitutes a 
virtual earth. The phase relationship between the input and 
output signals of such an arrangement changes from inverting to 
non-inverting at frequencies at which the gain of the amplifier 
drops to below unity, because of forward feed through the 
feedback impedance (9), thereby upsetting the phase relationship 
between the signals passing through the arrangement and those 
passing through the coupling. Accordingly a further impedance 
(10), e.g. a capacitance, is provided between the common point 
(11) of the series and feedback impedances and ground. At 
frequencies at which the amplifier gain is high this has 
virtually no effect, because of the virtual earth existing at the 
common point (11). However, at frequencies at which the 
amplifier gain drops to unity or below the virtual earth effect 
is lost and the further impedance forms a potential divider with 
the series impedance (7), reducing the proportion of the input 
signal which can take the direct forward path through the 
feedback impedance.

Title: Methods of and apparatus for recording signals on a disc-shaped recording medium
IPC: G11B20/10
Filed: 1987-02-12
Abstract: When a time-sequential signal such as an analog or digital data signal is recorded on a disc-shaped recording medium (11), the transmission rate of the digital data is determined or the time-sequential analog signal is sampled at a predetermined sampling frequency to obtain time-sequential digital data which is sequentially recorded on the disc-shaped recording medium (11). The rotational speed of the disc-shaped recording medium (11) is controlled in response to the transmission rate of the time-sequential digital data. The transmission rate is recognised by a speed control signal generator circuit (36) either from clock signals derived from self-clocking digital data supplied to an input terminal (31D), or from a separate signal indicative of the transmission rate supplied to a terminal (31R). In the case of an analog signal supplied to an input terminal (31A), an analog-to-digital converter (32) sets the transmission rate and this is detected by the speed control signal generator circuit (36). The rotational speed of the disc-­shaped recording medium (11) is controlled by controlling the speed of a driving motor (21) by means of a phase comparator circuit (23), an integrator circuit (24) and a motor drive circuit (25).
Patent EP-0239389-A3 (EP)
IPC: B23K20/24
Filed: 1987-03-25
Abstract: An improved method is described for ball bonding an 
aluminum wire to a contact pad of a microelectric device. 
In ball bonding, the wire is fed through and protrudes 
from a capillary hole in a bonding head, an electric arc 
melts the protruding wire into a ball, the solid ball 
thus formed is pressed and flattened onto the contact 
pad by the bonding head and the ball-contact surface 
interface is subjected to ultrasonic vibrations to form 
a bond between the flattened ball and the contact pad. 
Aluminum wire has presented a problem in forming asym­
metric, porous, faceted balls that ball-bond very poorly. 
By using an aluminum wire coated with an electrically 
insulating layer that melts above the melting tempera­
ture of aluminum and has an electrical resistance suf­
ficient to prevent the electric arc from shifting up the 
wire and away from the tip, the problem of poor quality 
balls is solved and a round, axisymmetric ball is formed 
which ball-bonds consistently well.
