Title: Combined paper punch and binding apparatus
IPC: B26F1/04
Filed: 1990-07-03
Granted: 1993-01-14
Abstract: A paper punch and binding apparatus has two punch mechanisms, one for punching round holes in a paper sheets stack and one for punching rectangular holes in another paper sheets stack. A single lever or crank simultaneously operates and drives a series of round end punches to shear the round holes and a punch plate with integral rectangular punch elements shear rectangular holes. A four-bar linkage connects the lever to the punch plate and the series of the punches in a manner that both the plate and punches are driven in a vertical straight line and with a greater mechanical advantage at the start and over the first increments of the punching operation. In a preferred embodiment, a binding station is provided in an apparatus base portion particularly for binding with a Douvry-type plastic resilient loops binding element. The binding station has an operating knob which operates a simple gear interconnect train for uncurling the resilient loops and allowing the punched hole stack to be inserted thereon. In an additional embodiment two rows of large and smaller diameter punches are provided in one round punch mechanism with an apertured translatable bar for rendering inoperative one or the other of these rows of punches.

Title: Multi-focal spectacle lens having at least one progressive surface
Inventor: FURTER GERHARD
IPC: G02C7/02
Filed: 1986-07-29
Granted: 1989-10-19
Abstract: The invention contemplates a multi-focal spectacle lens having two progressive zones which are spatially separated from each other and which provide smooth transition of dioptric power, from one to the next of three different viewing-distance regions. This progressive surface is calculated in accordance with the technique of spline analaysis and is twice continuously differentiable. Such a progressive lens, which is illustratively described for use at computer-screen work stations, has an upper viewing-distance region designed for distant vision, a middle viewing-distance region designed for viewing the computer screen as well as a document arranged alongside the screen, and a lower viewing-distance region designed for near-vision requirements of keyboard operation. Laterally of the near-vision region the power of the lens decreases so that documents lying to the side of the keyboard can also be seen sharply, without moving one's head.

Title: Disc mascara applicator
Inventor: BOUIX HERVE F
IPC: A46B9/02
Filed: 2001-07-20
Granted: 2004-08-19
Abstract: A disc-type cosmetic applicator has a plurality of individual discs connected by integrally molded springs to yield a single disc array. The space between the individual discs of the disc array is compressible during withdrawal from a container so that excess product can be removed from the applicator by a wiper. After passage through the wiper, the springs between the individual discs are biased to return to the array to a fully expanded position. The compressing of the discs during withdrawal allows a controlled amount of product to remain on the applicator for application by the consumer, and the returning of the discs to their expanded position by the spring causes the discs to assume a configuration which allows the applicator to effectively comb and separate the eyelashes. The single unit construction of the multi-disc array allows efficient and convenient assembly of a complete applicator by securing a single disc array to a conventional applicator stem with a simple pin.

Title: Device for manually applying self-adhesive film to a curtain rail - using film reel adjustably spaced from a pressure roller
IPC: B29C63/02
Filed: 1971-04-16
Abstract: A manually operated device for applying a self-adhesive plastics tape to a curtain rail or venetian-blind bar comprises a supply roll for the film and a pressure roller which are both rotatably supported between parallel side walls. To effect application, the film, which passes underneath the pressure roller, is drawn-off in the longitudinal direction of the rail whilst the device is being pressed-on and then moved back. The side walls for the supply roll and the side walls for the pressure roller are adjustably connected with a base plate for guiding the applied film. This also allows adjusting the distance of supply roll from pressure roller. The side walls protrude laterally beyond the base plate so as to facilitate guiding the device along the rail. This protrusion (or overhang) amounts to less than the thickness of the rail. The construction ensures improved guide control of the applicator during operation. Reliable application of the self-adhesive film is independent of the pressure exerted by a user onto the pressure roller.

Title: Self supporting winding for electrical machine - has skewed conductors and end connections at one end only
IPC: H02K3/04
Filed: 1971-05-26
Abstract: The winding space utilisation of a small self supporting winding for an electrical machine, is improved by an asymmetrical arrangement of the coil ends. At one end the end windings form a chord across the armature diameter. At the other end the active conductors change direction at a point on the cylindrical surface. The conductors run at an angle across the cylindrical surface. The proposed construction makes the angle between the coil sides a selectable quantity, and not dependent upon the ratio of armature diameter to active length. This allows a greater freedom in winding design.

Title: Electronic instrument keyboard circuit - controls tone generation according to keyed voltage rise time representing keying impact
IPC: G10H1/053
Filed: 1972-03-17
Abstract: A keyboard for electronic musical instruments generates control voltages according to the degree of impact on each key to control electronic valves for the individual tones of the register. These tones are fed to the amplifying system. The circuit modifies the rise time of the voltage corresponding to each tone valve. The network consists only of resistances, which may form voltage dividers for each tone valve. The key (11) may close the contact (12) so that the condenser (14) charges through the resistance (13) to a voltage (UA) which controls the tone valve through the transistor (15). The tone valve is a current-operated switch with transistor (19).

Title: Multi-circuit brake system control - has valves operated via single spring with radial arms one of which is longer and separately spring to act in advance of others
IPC: B60T15/04
Filed: 1973-01-17
Abstract: The separate control valves (4, 6) for the different brake circuits are arranged in a cluster about a central vertical axis. They are operated by a master control element via a single spring with radial arms (11) leading to each valve. At least one of the arms is longer and is braced at one point by a separate spring. The special arm operates its valve slightly in advance of the others. This provides a loading signal for the trailer brakes and prevents slewing of the towing vehicle and trailer.
