IPC: H01H13/08
Filed: 1982-01-27
Abstract: A portable electric tool has an elongated lever (16) pivoted (22) intermediate its length and contained fully within the tool housing (2). The rear end (42) of the lever (16) operates a reversing switch (14), and the forward end (24) of the lever engages in an actuating member (28) slidable along a transverse slot (74) in the lower wall (34) of the motor compartment (6). Intermediate the forward end of the lever (16) and its pivotal axis (22), a downwardly projecting pin (36) coacts with a partition (40) in the upper part of the trigger (12) of a trigger-switch (10) to prevent pivoting of the lever (16) while the trigger (10) is in an inward position energizing the tool. A brush-board assembly (56) is rotatably mounted in bearings (106, 112), and has a stud (66) engaged by an upwardly extending forked arm (68) of the lever (16). With the trigger-switch in the "off" position, the lever (16) is pivoted by the member (28) to simultaneously rotate the brush-board assembly (56) and actuate the reversing switch (14) for the chosen direction of rotation of the motor (44).

Abstract: Apparatus for forming a bend in sheet material comprises two pivotally mounted jaws (10 and 12) between which is a gap (13) for receiving sheet material (14) which is fed incrementally or indexed through the jaws (10, 12) in the direction of the arrow 15. Rotation of one or other jaw by a controlled amount, together with a controlled extent of incremental feed of the sheet material (14) applies to the sheet material a number of incremental bends which in total form the desired curved profile to be introduced in the sheet material. Other embodiments (Figures 3 and 4) use linearly movable heads to engage the sheet material as the latter is incrementally fed, instead of pivotally movable jaws.

Abstract: quantitative corneascope for use with a surgical microscope in performing corrective techniques on the eye includes a pair of hinged image projection housing members (29) movably mounted on each side of a surgical microscope (11) and a light and image source for reflecting partial segments of placido rings (mires) from the corneal surface of the eye. The microscope utilizes a beam splitter to provide multiple viewing by an operating doctor, an assistant and a television camera. The camera permits viewing of the mires as reficeted from the eye, on a monitor. The monitor is provided with apparatus for generating cursor lines on the viewing surface, which cursor lines represent predetermined radii of curvature corresponding to the range of spherical eye shapes. The cursor lines may be adjusted to discrete values in this range of radii of curvature which in turn changes the spacing between the straight lines of the cursor display. The cursor lines may also be adjusted along the X-Y coordinates of the viewing surface. 
     The use of this instrument involves placing the microscope and surgical corneascope muonted thereon over the patient's eye at a fixed distance. A focus mark is displayed on the viewing surface to accommodate this adjustment. The mires may be reflected from the eye and displayed on the viewing surface. The cursor lines are brought into coincidence with the mires to provide an image of the preoperative condition of the eye. This information relating to the pre-operative eye condition is stored for later use. 
     The surgical procedure is then performed together with suturing of the eye. The corneascope is again brought into its operative position to show the present condition of the eye as compared to the cursor lines which are set to coincide with the pre-operative shape of the eye. The sutures are then adjusted to bring post-operative shape into alignment with the pre-operative shape. Other uses involve bringing a post-corrective shape of the eye into coincidence with a predetermined shape to provide corrected refractive shape to the corneal surface. The quantitative aspect of the mires permits real time refractive error measurement which when compared with cursor lines relating to a predetermined corneal curvature, permit real time correction of refractive error.

Abstract: In such bodies, in particular for musical instruments, loud speakers and the like, there is the problem of damping undesirably strongly prominent higher frequencies. As a solution, the sound-radiating surface (SF) is provided at least partially with a fine-grained granular material (GR). At the same time, a force-transmission joint is produced between the granular material and the surface by a binder (BM) which is preferably solid, but may possibly also be viscous. The latter produces relatively strong frictional damping in certain frequency ranges, whereas the former operates more as a result of increased mass coating. Preferably, metals, in particular heavy and noble metals, are suitable for the granular coating. <IMAGE>

Abstract: The implication of lymphokines in the body's defense mechanism against leprosy makes them suitable pharmaceutical agents to combat this disease. Either IL-2 or -interferon, separately or together may be administered as a therapeutic agent to an indivdiual suffering from leprosy. When used as anti-leprosy agents the lymphokines may be administered topically at sites of injection or may be administered systemically. 
     It has been found that peripheral blood mononuclear cells from 10 out of 10 lepromatous (LL) patients displayed no release of y-IFN upon stimulation by the specific antigen. In contrast, 6 out of 6 tuberculoid (TT) patients, and borderline tuberculoid (BT) had strong y-IFN responses. The low responsiveness to antigen of some of the borderline lepromatous cases (BL) case suggests that this assay can be helpful in evaluating the prognosis of the disease, suggesting which patients display suppression of cell-mediated responses and would tend to follow the lepromatous course.

Title: Analogue wave filter device
Inventor: SHARPE ROBIN
IPC: H01L27/01
Filed: 1984-02-20
Abstract: An RC active filter device which is implemeted with integrated circuit technology. Each RC filter element of the device has a distributed series resistance and a distributed shunt capacitance. The series resistance is formed by a strip of resistive material which overlies a resistive plate (or substrate) with an intervening insulating layer to form the shunt capacitance. The filter device can be designed to have a pass-band ripple response which is not affected by variation in nominal absolute resistance and capacitance values resulting from process spreads. These variations only stretch or compress the filter response along the frequency axis. The filter device shown in Figure 2 comprises three RC filter elements 1, 2 and 11, and an operational amplifier 3. The RC filter elements 1 and 2 determine a low pass band. The filter element 11 prevents high frequency components outside the low pass band being leaked directly to the filter device output.
