Patent EP-0296091-A3 (EP)
IPC: B62B5/04
Filed: 1988-06-13
Abstract: A brake, suspension and wheel locking unit for baby 
carriages, of the type comprising a terminal bracket 
(1) on the frame members (2) to which the support (11) 
of the shaft (12) of wheels (13) is pivotably mounted 
and which comprises a pivoted brake lever (10) and a 
suspension spring (20) between said terminal bracket 
(1) and shaft support (11), the object of this inven­
tion being to provide on the four frame members of the 
carriage a unit comprising: the terminal bracket (1) 
for the frame members, a locking arm (5) pivotably 
mounted to said bracket and locking a finger (14) which 
is an extension of the wheel holder support (11), which 
is pivotably mounted to a projection (9) of a bushing 
(8) rotatably mounted on the terminal bracket (1), to 
which projection (9) there is also pivotably mounted an 
angle brake lever (10) extended by one of the arms

Patent EP-0275246-A3 (EP)
IPC: B01J10/00
Filed: 1988-01-14
Abstract: In accordance with the practice of this invention there 
is provided an improved apparatus for the preparation of chlorine 
dioxide which employs an improved chlorine dioxide generator 
comprising a small reaction chamber (15) with means for injecting a 
concentrated metallic chlorate solution (35), a concentrated sulfuric 
acid solution (40), and gaseous sulfur dioxide (45). The sulfur dioxide 
gas is injected into the reaction chamber from the bottom through a 
porous medium (23) which disperses the gas as extremely fine bubbles 
into the aqueous reaction medium in the chamber.  
     The reaction chamber is equipped with an internal 
Teflon braided cooling coil (65) inserted therein which not only cools 
the reaction medium but also provides a tortuous path for the 
sulfur dioxide bubbles. By retarding the upward path of the 
bubbles, the sulfur dioxide is held in solution for a longer period 
of time allowing more time for reactant gas dissolution and 
corresponding chemical reaction.  
     The reaction chamber is maintained under 
superatmospheric pressure so that the chlorine dioxide that is 
produced is maintained in solution. Keeping the reaction chamber 
under pressure, as opposed to atmospheric pressure operation, also 
promotes sulfur dioxide solubility. Because the chlorine dioxide 
isn't handled in a separate gas phase, operation of the unit is more 
simple and inherently safer than prior art systems which handle 
chlorine dioxide as a gas.

Title: Electrophotographic photoreceptor and method of producing the same
IPC: G03G5/05
Filed: 1989-06-06
Abstract: Disclosed is an electrophotographic photoreceptor in 
which an organic lubricant (6) is provided on the surface of an 
organic photoconductive layer (5) or on a protective layer(11) 
formed on the organic photoconductive layer. Elements (8) of 
the organic lubricant are partly exposed from the surface 
of the organic photoconductive layer or the protective 
layer while the remainder portions (7) of the elements 
embedded or fixed by chemical reaction in the surface 
region of the photoconductive layer or the protective layer 
so that the exposed portions of the elements of the organic 
lubricant provides a lubricating surface layer. The 
lubricating surface layer suppresses wear of the 
photoreceptor thereby enabling the photosensitive layer to 
withstand a long repeated use without impairing 
electrophotographic characteristics.

Low-speed interfaces respectively receive the demultiplexed TDM signals to 
detect the time slot in which the alarm signal is contained and transmits a 
line fault signal to a respective one of low-speed transmission lines.

Title: Method and apparatus for advance warning signalling to a motorist of an ice condition on a driving surface
IPC: G08B19/02
Filed: 1990-01-17
Abstract: A method and apparatus for advance warning signal­
ling to a motorist of an ice condition on a driving surface. 
The method steps include mounting a plurality of traffic 
signalling devices along a driving surface for sensing the 
prevailing temperatures and thereby continuously signal a 
motor vehicle operator of the changes in temperature as he 
approaches a driving surface subject to freezing to permit 
him to take any necessary precautionary corrective action 
in driving the motor vehicle. The signalling devices 
utilize thermostat elements for sensing a narrow temperature 
range adjacent the freezing temperature and provide visible 
signals, preferably two colors for signalling a warm or non-­
hazardous temperature, a cold temperature signalling a 
frozen driving surface or a combination or mixture of the 
colored signals to permit the motor vehicle operator to be 
warned, in advance, as he appraoches a driving surface that 
is becoming colder, leading to a stretch of a driving 
surface that may be frozen.

Title: Method and apparatus for washing circuit boards
IPC: H05K13/00
Filed: 1990-01-30
Abstract: The present invention concerns a method for washing off 
flux residues subsequent to soldering from a circuit board 
or equivalent component. The circuit board washing procedures 
of prior art have either been detrimental to the 
environment or poor in their washing result. These problems 
have in the present invention been solved by including at 
least one step in the procedure in which steam is sprayed 
on the circuit board or equivalent. The steam spraying step 
is advantageously combined with preceding water washing and 
rinsing steps. A circuit board or equivalent component 
rinsed with hot steam is recovered in a cleaner condition 
than before, and moreover, entirely dry.

Abstract: The invention relates to a support (1) for an electric motor (4) of a kitchen machine, in particular a lemon squeezer, which has a board (2) consisting of insulating material with a holder for the attachment of the motor (4). Constructed on the board (2) are end sections (13 to 16) which can be connected via connecting cables (which are not shown) to an electrical power source and which are used for the connection of contact tabs or contact pins (18) which are constructed on the motor (4). The contact pins (18) are connected to the end sections (13 to 16) in the form of touching contacts. The end sections (13 to 16) are constructed on conductor tracks (5 to 8) which are stamped out of sheet metal and are constructed to be elastically deformable in such a manner that the contact pins (18) of the motor (4) can be pressed in a resiliently elastic manner against the end sections (13 to 16) when said motor is being displaced in the longitudinal direction of the motor axis. Contact tabs (23, 24) which are adjacent to one another on the conductor tracks (5, 6) are integrally formed in order to form a switch, one of which contact tabs (23) can be pressed against the other contact tab (24) by elastic deformation, with the aid of a moveable operating element (27). In consequence, a connection of the contact pins (18) of the motor (4) to the end sections (14, 15) which are constructed on conductor tracks (5 to 8) is formed in a manner which can be produced cost-effectively and can be installed easily, the conductor tracks (5 to 8) also forming an electrical switch (23, 24) at the same time. <IMAGE>

Title: Photomultiplier tube
IPC: H01J43/26
Filed: 1992-01-10
Abstract: A photomultiplier tube includes a tube (1), a focusing 
electrode unit (6,7) formed with a photoelectron 
transmission hole (8) whose centre is positioned offset 
from a central axis of the tube (1) and a dynode (10) 
positioned in confrontation with the transmission hole (8). 
A centre of the dynode (10) is also offset from the central 
axis of the tube (1). A grid type electrode array (11) is 
positioned at the same axial position as the dynode (10) 
and positioned beside the dynode (10) in the radial direction 
of the tube (1). The focusing electrode (6,7) 
provides desirable uniformity in distribution of 
photoelectrons over the dynode even though it is offset 
from the central axis. By positioning the dynode (10) away 
from the central axis in the radial direction of the tube, 
the grid type electrode array (11) can be positioned beside 
the dynode (10). Thus, entire length of the tube (1) can be 
reduced without any increase in the diameter of the tube (1).
