Title: Pocket dispenser for powdered saccharin - has rectangular cross section to provide ample capacity in compact size
IPC: A47G19/24
Filed: 1968-10-16
Abstract: The pocket dispenser for powdered saccharin (1) has a case of rectangular cross-section with semi-circular ends. The saccharin storage section (4) is divided from the upper section (3) by a partition (2). The upper section (3) houses the actuating cap (5) which is held in the closed position by a spring (6).

When the cap (5) is pressed downwards the collar (18) is brought into contact with the edge of the hole (14) allowing the saccharin trapped in the hole between collar (18) and cone (16) to be ejected.
Patent DE-1965220-B2 (DE)
Title: Miniature hysteresis motor - has spring coupling between rotor and shaft helping to demagnetise additional clapper type armature
IPC: H01F7/08
Filed: 1969-12-29
Abstract: The present design minimises the danger of the clapper type armature (8) sticking to the auxiliary pole faces when the motor is switched off. The rotor (13) is joined to the shaft (17) by a spring coupling (18, 19, 20, 21) such that when the motor is switched off the rotor is moved through a short arc by the energy stored in the spring. If switch off was at full flux in the stator the subsequent motion of the rotor hysteresis elements would induce a demagnetisation cycle enabling the armature to drop off. In addition the facility permits the use of weaker pull off springs (10) and very small or non-existant air gaps.

Title: Gas lubricated rotor bearing system - is protected against overloading by a permanent magnet overload coupling
IPC: F16C17/20
Filed: 1970-11-24
Abstract: The rotor bearing system has a gas lubricated main bearing. The bearing plate which supports the rotor journals is stationary under normal operating conditions. However, this plate rotates together with the rotor when a certain torque is exceeded. The arrangement prevents damage to the bearing faces of a gas lubricated bearing due to excessive out of balance of the rotor, shock loading, dirt in the lubricant gas or failure of lubricant gas supply. Between the bearing part formed by the shaft (14) and the fixed component (20) is fitted a permanent magnetic overload coupling with magnetically conducting projections (23) on the shaft. The permanent magnets (22) are fitted on the fixed component.

IPC: G01P3/488
Filed: 1971-10-01
Abstract: A slip detector for vehicle wheels has a sensor on each wheel producing wheel peripheral speed dependent signals which are converted into pulses of interval corresp. to peripheral speed in a pulse generator. The circuit has temp. and frequency stability of the duty cycle of the rectangular output pulses. The duty cycle is also less sensitive to the pulse generator coil impedance, component tolerances, and supply voltage variations. The generator coil (28) ends are connected to the bases of a differential transistor amplifier pair (80,81). The commoned emitters of the pair are connected via a resistor to the generator output (56). One transistor (81) base is supplied from a potential divider (87,88) and its collector drives a switching transistor (58) with a coupling resistor.

Title: Direction finder using single antennae in arc - uses computer to compare rotating direction pattern with theoretical pattern to give bearing error
IPC: G01S1/02
Filed: 1972-01-13
Abstract: The direction finder uses single antennas located on a circular arc and connected together to generate a rotating direction pattern. A delay network contg. by-pass lines sets the main group beam directions and drives a switching matrix to scan neighbouring antennas by steps. A computer compares the antenna signals with the theoretical antenna group radiation field to give the bearing error. The direction patterns of several main beam directions are simultaneously evaluated so that a single antenna may belong to only one group at any time.

Title: A foaming nozzle
Inventor: MADDEN THOMAS
IPC: F15D1/08
Filed: 1996-01-19
Abstract: A foaming nozzle (1) is provided comprising an inlet (2) having a first diameter, an outlet (3) having a second diameter greater than the inlet diameter, and defining therebetween a stepped chamber (14) comprising successively increasing diameter portions (5,6,7) each greater than the inlet diameter but less than or equal to the outlet diameter of the nozzle, each stepped portion comprising a plurality of air ducts (11,12,13) communicating with the nozzle exterior. Such a nozzle is used to introduce air to a water-based foam-forming solution for example containing detergent, or the like, in order to produce a very fine foam in relatively high volume. For example, in many industrial applications there is a need to produce a very fine foam which is capable of adhering to a surface and which does not degrade quickly in ambient air, to give time for a detergent, for example, to act upon the surface being treated.

Abstract: An ink-jet printing apparatus performs a printing process by discharging ink from color ink heads (30C, 30M, 30Y, 30K) and treatment liquid from a liquid head (31) for making the ink insoluble or coherent. The printing apparatus has the minimum amount of memory (114) to be required to eject the treatment liquid as far as possible and performs excellent printing. For discharge data of one scanning performance of the color ink heads, the apparatus has only memories (101, 102, 103, 104) for each color ink head (30C, 30M, 30Y, 30K). Discharge data for the treatment liquid is formed by a treatment liquid discharge data creating portion (113) based on the data stored in the memories (101, 102, 103, 104) upon switched by data-switching portion (121, 122, 123, 124). Then the discharge data for the liquid head is supplied to the head (31) after being stored in a buffer (114) as much as the number of orifices of the head. <IMAGE>
