Filed: 1982-09-01
Abstract: A surgical stapler including a stapling assembly, an actuator assembly remote from the stapling assembly, and a longitudinal shaft assembly having a longitudinally curved section for connecting the actuator assembly to the stapling assembly and for transmitting the forces and motions required to operate the stapling assembly from the actuator assembly to the stapling assembly.

Title: Driver circuit for printers, in particular for matrix printers of the needle or hammer type
IPC: H01F7/18
Filed: 1982-09-27
Abstract: The drive circuit for an electromagnetic actuator for the impact element in a printer includes a series circuit of a drive transistor and of a switching transistor there being a reference resistor interposed which together with a Zener diode serves as a current limiter for the current through the drive transistor and the electromagnetic element. The two transistors are controlled in that each of the base electrodes is serially connected to the emitter collector path of a control transistor and the two control transistors in turn are connected to monostable multivibrators which are triggered concurrently but furnish pulses of different duration such that the switching transistor is turned off before the drive transistor. The current limiting permits utilization of residual electromagnetic energy from the preceding actuation pulse without incurring undue losses.

IPC: G01N27/62
Filed: 1985-07-13
Abstract: The instant invention relates to a mass spectometer 
having an inlet leak and a flow-by sampling arrangement. In 
accordance with the invention, aerosols and solid impurities 
are removed from the sample by packing a portion of the 
flow-by tubing prior to the inlet capillaries or the inlet leak of 
the mass spectrometer with a packing material coated with a 
suitable nonvolatiie liquid. The packing must have the 
spaces between the particles thereof small enough to 
remove fine particles while still permitting adequate flow. 
With this apparatus the solids are collected by simple 
filtration through the packing material while the aerosols 
flowing into the packing are partitioned into the nonvolatile 
liquid coating the particles and are released at a later time 
into the sample stream as a vapor or gas.

Abstract: An improved method of reducing a binary digital image 
in size by a factor F by storing the image in bit sequence; 
removing one or more rows of bits along the vertical axis of 
the image to convert i rows of bits to j rows of bits where 
0.5i<=j<i; modifying a line adjacent to each line discarded to 
preserve selected information from the discarded line; re­

mined number of times to achieve a reduction by a factor F1 
along the vertical axis; rotating the image in a first direction 
by ninety degrees; removing one or more rows of bits along

bits to j rows of bits where 0.5i<=j<i; modifying a line adjacent 
to each line discarded to preserve selected information from 
the discarded line; repeating the steps of removing and mod­
ifying a predetermined number of times to achieve a reduc­
tion by a factor F2 along the original horizontal axis; rotating 
the image back to its original orientation; storing the reduced 
size image generated by the above steps.

Title: Process and apparatus for eliminating so3, sulfuric acid and sulfuric-acid mist from flue gases
IPC: C01F11/46
Filed: 1985-10-15
Abstract: The removal of SO3, sulphuric acid and sulphuric acid mists from flue gases of wet desulphurisation plants in the combustion of sulphur-rich coals is improved by spraying at least one separator layer of a demister system with a quantity of caustic soda, soda, aqueous ammonia or mixtures thereof, which is in excess relative to the total residual quantity of sulphuric acid in the gas. About 95% of the residual sulphuric acid in the pure gas can thus be removed. The alkali solutions flowing back into the reaction vessel do not interfere with the remainder of the desulphurisation process and the formation of large gypsum crystals.

IPC: A01B49/06
Filed: 1985-05-01
Abstract: For successively preparing the sowing bed in front of a 
sowing machine there is mounted, in front of the sowing 
machine, a harrow-like implement having stiff teeth, the 
lower ends of which are provided with rearwardly and 
laterally projecting scraper blades, which are slightly screw 
twisted rearwardly. These scraper blades act to plane off and 
laterally displace the surface layer of the ground, whereby 
the earth in this layer is effectively loosened. The implement 
is carried by a grid drum. The scraper blades behind 
consecutive rows of teeth are laterally inclined to mutually 
opposite sides, whereby the earth as displaced firstly in one 
lateral direction will get displaced back again into its original 
position, without any significant resulting displacement. The 
stiff teeth may have a lower free end portion drawing 
draining grooves in the bottom of the sowing bed as 
prepared by the scraper blades. The implement will effective­
ly prepare the sowing bed solely by the general propulsion of 
the implement, i.e. without separate powering of individually 
movable working tools.

Abstract: An electrically assisted pedal cycle is provided having 
a drive unit 10 pivotally mounted to a frame 16 adjacent a 
wheel 24, the unit comprising a drive motor 20 and, opera­
tively connected thereto a wheel engaging drive roller 22, the 
centre of gravity of the unit being arranged in relation to the 
pivot 12 such that the drive unit 10 hangs clear of the cycle 
wheel 24 when not under drive conditions.  
     The drive unit 10 can also be used in such a way that the 
drive roller 22 comes into contact with the ground surface 
instead of the cycle wheel 24.  
     A distinct advantage of the invention is that it does not 
require a clutch or other manually operated mechanism to 
bring the drive roller 22 into and out of engagement with 
either the cycle wheel 24 or the ground.

Title: Backflushed air filters with quick opening multiple discharge valve
IPC: F16K7/17
Filed: 1986-10-03
Abstract: Pleated paper barrier type air filter elements are cleaned by a reverse air jet cleaning system which includes one or more specifically shaped cleaning air valves (74) in which a plurality of jet nozzles or orifices are arranged in a predetermined pattern to provide a totally enveloping air jet which is discharged into a flow tube immediately downstream of the clean air flow chamber of a generally tubular filter element. The jet pattern provides a temporary pressure seal within the flow tube and entrains a substantial amount of ambient air into the reverse flow jet to thoroughly flush elements to clean dust cake from the exterior surfaces thereof. The multiple jet arrangement reduces the overall space occupied by the reverse jet cleaning system and provides a larger mass flow of cleaning air. Multiple jet orifice valves may be configured in virtually any geometric shape to provide a desired jet pattern.
