Title: Machine for compressing straw, hay and the like into balls
IPC: A01D85/00
Filed: 1981-01-27
Abstract: The agricultural baling machine for forming hay, straw etc. into circular bales has a triangular chamber formed by endless belts, inside which the material is rolled. This chamber is formed by a horizontal belt (12) and the bases (13,14) of two upper belts passing around rollers to form two isosceles triangles, these two belts rotating in opposite directions. These rollers (15,16,17;18,19,20) are carried by frames so that they can be swung apart to eject the bale when rolled to a maximum size. The two frames carrying the rollers are attached to springs (22,23) which enable the chamber to increase in size to match the size of the bale as it is rolled. The outermost roller (16,20) is attached to a bell crank lever (31,32) connected to a spring at the other end. A deflector plate behind the horizontal conveyor, which assists formation of the bale can be swung down during bale ejection.

Abstract: A wheeled land vehicle in which at least one free-running ground-engaging wheel (4, 5) has power take-off means connected thereto for providing power in or on the said vehicle, comprising a drive shaft (6) coaxial with and drivingly connected to said ground-engaging wheel and extending inwardly therefrom through a non-rotary hollow axle shaft (1) which mounts the wheel at its outer end.
Patent EP-0075872-A3 (EP)
IPC: F02P19/02
Filed: 1982-09-23
Abstract: An engine auxiliary start igniton system for a multi-­
cylinder diesel engine which forcedly ignites an air-fuel 
mixture supplied into each combustion chamber after actua­
tion of an engine starter motor, preferably when an engine 
cooling water temperature is below a predetermined value. 
The engine auxiliary start system is continuously actuated, at 
least until the engine has achieved a spontaneous ignition 
state or preferably until a predetermined period of time after 
the engine has achieved the spontaneous ignitable state. A 
detecting means for detecting the spontaneous ignition state 
of the engine includes (a) a combustion pressure detecting 
means which detects combustion pressure within a combus­
tion chamber and outputs a signal when the combustion 
pressure exceeds a predetermined value, (b) an engine 
speed detecting means which detects engine speed and 
outputs a signal when the engine speed exceeds a predeter­
mined value; (c) an oxygen concentration detecting means 
which detects the concentration of oxygen in exhaust gas 
and outputs a signal when the concentration of oxygen 
exceeds a predetermined value; (d) an engine starter motor 
stop detecting means which outputs a signal indicating that 
the starter motor has stopped; (e) an exhaust gas tempera­
ture detecting means which detects exhaust gas temperature 
and outputs a signal when the exhaust gas temperature 
exceeds a predetermined value; or (f) an engine cooling 
water temperature detecting means which detects engine 
cooling water temperature and outputs a signal when the 
engine cooling water temperature exceeds another predeter­
mined value. When the engine auxiliary start system re­
ceives the output signal from any of the ignition state 
detecting means, the ignition system for auxiliary starting 
the diesel engine stops so that air-fuel mixture is ignited 
stably without misfire and the engine revolves smoothly.

IPC: G07D5/02
Filed: 1982-03-18
Abstract: Discrimination between two coin-denomination (Xp, Yp) 
of equal diameter but different thicknesses, is made in a 
coin-sorter by sweeping the coins round an 
annular plate (10) in abutment with the inner edge (13) of an 
upstanding rim (11) which in the region of a sizing aperture 
(143) for receiving the thinner denomination (Xp) is undercut 
to admit coins of that denomination, but not of the other, 
thicker denomination (Yp), into abutment with an outer 
auxiliary edge (17) such that only coins of the thinner 
denomination (Xp) will be accepted within the diametral 
threshold set for that aperture (143) from the auxiliary edge 
(17). The thicker coins (Yp), because they abut the undercut 
edge (13), lie outside this threshold but are accepted within 
the same threshold set from that edge (13) at the next 
aperture (144). In another sorter coins are 
tipped from an inclined and slotted shoulder (30) by 
deflectors (35 to 37) depending upon diametral thresholds 
set from the top (38) of the shoulder (30) or the bottom (40) of 
the slot (39) according to coin thickness, whereas in other 
apparatus discrimination is made photoelectroni­
cally in response to coins which run along different rails (60, 
61) according to their thicknesses (or other characteristics).

Patent EP-0122092-A3 (EP)
IPC: C23C14/56
Filed: 1984-03-30
Abstract: A vacuum metallizer comprises a vacuum chamber split 
into a number of sub-chambers by partitions (5 to 8). A ma­
terial transport mechanism (2, 3, 4) is disposed in one sub-­
chamber and metallizing sources (11, 12, 13) the others. Sub-­
chambers are individually pumped to provide close control of 
sub-chamber pressures. Sources are activated and when the 
length of material is drawn past them the metal of the sources 
is deposited thereon. Each partition comprises two sealed 
parts (20 and 21) one of which moves with the web transport 
mechanism whilst the other remains in the vacuum chamber 
when the chamber is opened. This enables a close gap to be 
maintained between partitions and mechanism which in turn 
restricts gas leakage between adjacent sub-chambers.

Abstract: The present invention briefly refers to equipment for 
closing conduits and comprises a closing lid (1) having two cir­
cular disks with a peripheral sealing ring of resilient material. A 
tightening device connects the two disks at the center thereof 
causing during tightening to compress the sealing ring radially 
outwardly. The tightening device is of very stable construction

movement between the closing lid (1) and the support plate 
(43) or a pulling movement between the closing lid (1) and the 
main clamp (39).

Abstract: A liquid flow sensing device which incorporates a flow 
sensor having a liquid flow passage through which liquid can 
flow. A first electrode is disposed with a first wall of the flow 
passage such that the electrode extends about a portion of the 
flow passage. A second electrode is disposed with a second 
wall of the flow passage in that portion of the flow passage 
about which the first electrode extends. The first and second 
electrodes are so disposed that at least portions of the elec­
trodes are in an opposing disposition. Electronic circuitry is 
coupled to the electrodes and in use of the device electronic de­
tection circuitry detects a varying capacitance between the 
electrodes as the amount of liquid flowing through the flow 
passage varies.  
     The flow sensing device is particularly suited for sensing 
milk flow in apparatus for the machine milking of animals. The 
sensing device includes a switching arrangement operable in 
response to detected liquid flow to open and close the flow pas­
sage and actuate a vacuum operated ram to remove teat caps 
from a milking animal.
