Abstract: Methods and apparatus for exercising or testing the strength of muscles in the lower trunk of the human body. The patient or exerciser is seated with his pelvis and legs fixed against movement and with his head, arms and upper back fixed relative to a movement arm (40) which extends above the seat (22) and is mounted for pivotal movement relative to the seat (22) about a horizontal axis (20). While the movement arm (40) is in a predetermined position, the patient applies a force through the upper back to the movement arm (40) to stress the muscles of the lower trunk, and the strength of these muscles is measured. To exercise these muscles, the movement arm is moved by a force exerted by the upper back against a bias of a resistance weight (W) to lift the weight, and then the force is released to lower the weight and the process is repeated. A compound weight system is employed to allow precise weight adjustment to suit the strength of the exerciser. The movement arm including the weight of the exerciser is balanced about the pivot axis by means of counterweights (110) including an adjustable counterweight (114).

Abstract: The catheter coupling has a hollow connection piece (10) into which a pressure element (18) can be screwed. In the cavity (12) of the connection piece (10) is the head (22) of the elastomeric clamping element (21). A tubular attachment (23) extends from the head (22) through the pressure element (18). The catheter (15) is pushed onto a support cannula (27). Upon tightening the pressure element (18), the head (22) is squeezed over the catheter (15). In addition, the attachment (23) is twisted. By means of the squeezing and the twisting, the internal diameter of the clamping element (21) is reduced so that the latter lies sealingly around the catheter (15). In this way, a considerable sealing length is obtained. The clamping element (21) is connected to the pressure element (18), so that the entire catheter coupling consists of only two parts to be handled.

Abstract: In double-walled refrigerator containers in which a base-plate (2) with T-shaped supports (3, 4) extending longitudinally thereon forms the loading surface, the problem arises that, particularly in the event of abrupt local stresses caused by the loading vehicles and by projections on the loads to be transported, the floor may be damaged and, in particular, the bond between the base-plate (2) and the insulation (11) destroyed, greatly reducing the stability of the container as a whole. A container which is insensitive to such damage can be achieved in that the base-plate (2) is corrugated, the wave crests (6) are situated at the location of the T-shaped supports (3) and the base-plate (2) is clamped to the insulation (11) by means of anchoring points (7). <IMAGE>

Abstract: In this method, a defined temperature zone is produced and spatially delimited immediately prior to the deformation zone where the strand-shaped stock, such as wire, tube, strip, bar or section is deformed. To produce this temperature zone, part of the quantity of heat arising during deformation and fed back counter to the direction of motion of the stock is used. Simultaneously with the formation of the temperature zone, a reaction space with a temperature higher than the ambient temperature is produced and a temperature range set such that the coating material applied to the stock becomes plastic or liquid in the reaction space and passes through the deformation zone in this state. The device comprises one or more elements (6, 8, 10), such as flat or curved plates, screens, nets or tubes, which are arranged in such a way in front of the deformation device (2, 3, 4) that they have no direct contact with the strand-shaped stock (1) and are connected to the following deformation device (2, 3, 4) via heat conductors (5).

Abstract: A filter, for protection against the sun, of improved contrast sensitivity has a spectral transmission (T lambda ) which for wavelengths ( lambda ) of the incident radiation in the range  lambda < 350 nm </=1% and in the range 350< lambda <400 nm is less than 20%, and which in the range 400< lambda <500 nm reaches a value of 5-30% and thereafter, proceeding from the value for T500, increases linearly with the wavelength to its maximum value. This progression is achieved by coating or colouring the filter material. In this case, it is advantageous to provide a component of the coating or colouring so that the spectral transmission (T lambda ) outside the visible spectral range, i.e. for values  lambda >780 nm, quickly reaches a value <1% again. <IMAGE>

Abstract: A mechanical torque converting transmission for producing an output with variable, controllable speed and torque characteristics comprises a rotary input shaft (12) adapted for attachment to a rotary power source and connected to a main drive gear (20). The drive gear is meshed with a plurality of pinion gears (32) which are journaled for rotation on an arm assembly (24). An eccentric device (34) is driven by each pinion gear for creating a centrifugal force that cyclically urges the arm assembly (24) in alternating forward and backward directions with a pulsating motion during each rotation of each eccentric device. A clutch (36) is provided for allowing forward movement of the arm assembly while preventing movement in the backward direction during each eccentric revolution. A resiliently displaceable device (26) interconnecting the arm assembly and an output shaft transforms the pulsating motion of the arm assembly to a smooth rotational motion of the output shaft (28), thereby causing the output shaft to rotate at a different speed and torque from that of the input shaft. Controls can be utilized to activate or deactivate the clutch and also change the phase relationship of the driven eccentric devices in order to vary the transmission output under varying load conditions.

Abstract: A mobile radio transceiver comprises a portable transceiver and a vehicular power booster (20). The portable transceiver (10) generates RF transmit signal and sets the power of the RF signal at one of power levels. The power booster (20) is coupled by a connecting cable (18) to the transceiver (10) to receive the RF signal, and includes a first power detector (28) for detecting the power of the received signal. One of multiple reference voltages is identified as corresponding to the power detected by the first power detector. A gain-controlled power amplifier stage (22) amplifies the RF signal from the transceiver for coupling to an antenna (34). The output power of the power amplifier is detected and a gain control driver (27) responds to a difference between it and the identified voltage by controlling the power amplifier so that the difference reduces to a minimum. In a modification, the power amplifier stage is a class C amplifier and the booster additionally includes a preamplifier stage. A second gain control driver is responsive to a difference between an average output voltage of the preamplifier stage and a fixed value for controlling the preamplifier so that its output is maintained constant. The output of the second gain control driver is used to identify one of the reference voltages supplied to the first gain control driver as corresponding to the power setting of the transceiver.
