Title: Dryer for animal manure - with means to break up aggregates of prod. during drying
IPC: C05F/
Filed: 1975-06-06
Granted: 1979-11-30
Abstract: A drum dryer for animal manure breaks up the pieces during drying, to form a powdered prod. In known appts. the product balls and produces material which is still wet in the centre or if the centre is dry the outside is burnt. Use of the new appts. produces good material, dry throughout. In the pref. appts. there is an input hopper which is stirred. The feed falls on to a screw conveyor driven in common with the stirrer by a variable speed motor. The feed goes to a pair of concentric cylinders which rotate. The heating is automatically controlled and may use liq. or gaseous fuel. The outer cylinder is supported on rollers and the inner cylinder contains a number of blades or a train of screws of varying pitch. Air is fed between the cylinders and is thus preheated. The outlet of the cylinders is connected to a housing contg. a fan and on the same shaft a number of blades extending radially. The housing also has a number of vertical passages through which the material passes. The prod. is collected in a vacuum cyclone.

Title: Integratable amplifier for e.g. TV receiver
Inventor: JOHNSON FRED D
IPC: H03F/
Filed: 1982-04-02
Granted: 1987-01-28
Abstract: The amplifier responds to the input signal (12) to generate first and second signal currents (I1,I2) of which the amplitude increases, decreases, respectively, for an input signal negative-going transition. A current mirror (32) provides a third signal current (I3) which mirrors the first signal current in a first output current path (34). A further current mirror (36) provides a coupling between the second input current path (30) and a second output current path (38). A feedback resistor (50) acts on the input stage to cause it to respond to the difference between the input signal and the output signal, so as to increase the current in one of the output paths. One form provides a video amplifier of which the output signal voltage amplitude is variable between five volts and about 195 volts. The circuit is suitable as a video output stage in a TV receiver and has reduced power dissipation.

Patent PT-85044-B (PT)
IPC: A61K9/22
Filed: 1987-06-08
Abstract: A diffusional drug delivery device is described which an provide for delayed onset of therapeutic effect and for delivery of the therapeutic agent in predetermined temporal patterns at optimum rates. Delay means are provided between the agent reservoir and the surface through which the agent is released by diffusion to delay the release of agent at a therapeutic rate for predetermined times after application. Suitable means include a delay membrane disposed between the releasing surface and the agent reservoir which membrane is preferably free of undissolved agent and/or is initially impermeable to the agent and thereafter becomes permeable. One or more agent chambers defined by one or more of such membranes may be provided, whereby agents are released in a predetermined temporal patterns at optimal release rates. Delayed permeability enables programmed washout periods to be obtained from the sequential and concurrent application of devices for the administration of drugs, such as nitrates, to which patients may develop a tolerance on continous administration over extended time periods.

Title: Weight magazine for strength-training traction appts.
Inventor: MOBERG J
IPC: A63B21/062
Filed: 1986-05-05
Abstract: Each weight plate of the appts. comprises a cut flat iron of suitable dimensions, and a weight of five kilograms. On these plates are welded four pieces of bent round iron (2), two on each side, and displaced so that the round iron on the underside is aligned with that on the top side of the weight plate beneath. In this way, the weight plates are fixed one on top of the other, leaving an intermediary space between them. The radius of the round iron assists in guiding the superimposed weight plates into the correct position. The other function of the round irons is to guide the pins (3) so that these meet holes in fork structures (4) on the opposite side. Via wires, the uppermost weight plate is lifted, being guided by two guides via two bronze-lined bushes. The pins are inserted in fork holes with the uppermost weight plate in the rest position.
