Title: Pen needle
Inventor: EGAN PEARSE
IPC: A61M5/34
Filed: 2019-06-07
Abstract: A pen needle (10) includes a hub (34) supporting a needle (28) and a distal needle shield (14) that can retract to expose the needle during injection and return to the extended position after use and locked in the extended position cover the needle. A proximal needle shield (16) moves to an extended position with respect to the hub (34) to cover a proximal end (34) of the needle. A spring (64) extends between the distal needle shield (14) and the proximal needle shield (16) to bias each needle shield to the respective extended position. A locking member (78) on the distal needle shield cooperates with the hub to lock the needle shields in the extended position. An indicator (94) in the hub engages and couples to the distal needle shield (14) when moved to the retracted position. The indicator (94) moves with the distal needle shield (14) to the extended position where the indicator is visible through the distal needle shield (14) indicating that the pen needle is no longer usable.

Title: Venetian blind
IPC: E06B9/384
Filed: 1982-01-08
Abstract: In the venetian blind, at least two cords (18, 20) in each case pass through a number of slats. With the blind down, the slats are held by means of at least two cords (18, 20) extending transverse to the first longitudinal edges (12) of the slats (11) and at least two cords (18, 20) extending transverse to the other longitudinal edges (13) of the slats (11), these cords (18, 20) being provided with loops (19, 21) arranged at regular intervals. Each loop (19, 21) is in this case secured on one of the associated longitudinal edges (12, 13) by means of a clip-like securing part (22). In order to considerably facilitate the assembly of the blind prior to installation and the replacement of a defective slat (11) in the installed blind, a hook is formed on the ridge of each securing part (22), which hook is intended to receive one of the loops (19, 21) and can be brought into the closed position and open position by bending.   <IMAGE>

Title: Isolating switch for the damping register of convection furnaces
Inventor: PETZ GUENTER
IPC: H01H35/02
Filed: 1978-01-12
Abstract: The isolating switch to be arranged in the circuit of the damping register of convection furnaces exhibits a switch housing (17), which is fixed to the furnace housing, with a fixed contact (5) and a switching spring (3) which can be bent away from the perpendicular when the furnace housing is inclined. The switching spring (3) is connected via a plunger pin (28) to a plate body (25), freely supported in the switch housing, which can be tilted away by a weight (10). The isolating switch results in reliable isolation of the circuit of the damping register when the furnace housing deviates from the perpendicular operating position, which prevents unwanted overheating of the damping register. <IMAGE>

Title: Reel for a magnetic tape
Inventor: ADAIR HENRY
IPC: G11B23/037
Filed: 1978-01-24
Abstract: Each reel disc (4, 6) has two coaxial rings (26, 28, 30, 32), which run on the inside of the reel disc in the axial direction, the radially outer reel disc ring (26, 30) on each reel disc being accommodated on the corresponding radially inner part of the outer edge (10), and the radially inner reel disc ring (28, 32) on each reel disc being accommodated on the radially outer part of the corresponding intermediate ring (14, 16). The reel discs and their reel disc rings serve the purpose of supporting the outer edge of the reel core with respect to a radially inwardly directed bending and of transferring part of all the forces which act in the radial direction on the outer edge of the reel core and bend the latter inwards, for support, onto the intermediate rings. This arrangement withstands the pressure which the wound magnetic tape exerts on the reel core, in particular when there are temperature variations. Use occurs in particular in the case of magnetic tape reels for computers. <IMAGE>

The flow rate of cement fluid is also measured (27) and the data supplied to the central controller, which regulates delivery (17) of cement fluid.   The flow detector may be electromagnetic, a paddle wheel counter, a "Woltmann" turbine or an oval wheel counter. The pump may be a peristaltic, centrifugal or eccentric screw type. The conduits that carry the additive and the cement are flexible, with detectors inserted in the hoses.

Title: Plastics spacer for concrete reinforcing bars - has extruded solid hub and equispaced helical arms allowing section area variations
IPC: E04C5/20
Filed: 1975-01-24
Abstract: The extruded plastics for concrete reinforcing bars have in cross section a solid hub with uniformly spaced radial arms. The spacer can have four, six or any other number of arms. The uniform spacing of arms is useful because no attention need be paid to the given angles of arms. The extruded cross section can be a helical shape, generated by rotating the profiles on extruding. The extruded profile can be also stretched by increasing the drawing speed above the extrusion speed. The cross section of the spacer can be varied within certain limits without changing the profile die of the extrusion machine.

Title: Measuring packing thickness of printing machine rubber cylinders - using inductive head and comparison signals in bridge cct.
Filed: 1973-04-02
Abstract: The arrangement for measuring the packing thickness of the surface of rubber cylinders on printing machine, so as to ensure uniformity and obviate strips on the print, incorporates an inductive layer thickness value indicator in a bridge circuit and a display instrument. The former comprises a coil in a magnetic core inside a housing arranged in a measuring head which is pressed against the rubber blanket of the printing cylinder and actuated by a micro-switch. Power supply to the coil is established by a voltage stabiliser. The circuitry is such that the inductive indicator giving the measured value of the layer thickness is in a different branch of the measuring bridge from a comparison indicator. The latter generates a signal relating to the radial distance of the rubber cylinder blanker from its lashing ring.

Patent CH-611985-A5 (CH)
Title: Pneumatic-oil control cylinder
Inventor: IMOBERDORF MARKUS
IPC: F15B11/076
Filed: 1977-08-22
Abstract: The cylinder is divided into two chambers (8 and 9) containing oil. The chamber (9) contains a piston carried by a tubular rod (20), which is actuated pneumatically. The oil expelled by this piston must pass through an annular space (49) located at the centre of a ferrule (13) carried by a wall (1a) separating the two chambers. A component (24), mounted in a sliding manner on the rod (20), is held so as to bear, by means of a spring (27), against a stop pin (28) carried by a rod (29) passing through the rod (20), the axial position of which is adjustable. The sliding component (24) bears, during the movements of the rod (20) and of the piston (41), on the ferrule (13), closing off the annular passage (49). The oil may then pass from one chamber to the other only via a sized passage (10), which determines a slow advance of the piston. Thus, the lengths of the rapid travel and that of the slow travel of the piston are adjustable. <IMAGE>
