Patent GB-651792-A (GB)
Abstract: 651,792. Calculating-apparatus. AKTIEBOLAGET ATVIDABERGS INDUSTRIER. Dec. 18, 1947, No. 33468. Convention date, Oct. 1, 1946. [Class 106 (i)] In a calculating machine having a driving shaft carrying cam discs, each co-operating with a mechanism which is normally ineffective, but which is rendered effective, by operation of a corresponding operation key, to engage the totalizer with actuators in appropriate timing, each such mechanism comprises two levers individually rockable on a common fulcrum, one being connected with a member for engaging the totalizer wheels with their actuators and the other being actuated by the cam disc and being detachably connected with the first lever by means of a connecting member controlled by the corresponding operation key. The invention is applied to a machine in which each totalizer pinion 1, Fig. 1, is coupled to an upper actuator rack 8 by a pinion 6 for addition and to a lower rack 10 by a pinion 7 to be rotated in the reverse direction for subtraction. The pinions 6, 7 are carried by a lever 3 which is connected to several operating mechanisms, one for each type of operation which the machine can perform. Depression of the subtraction starting key 39, Fig. 4, for example, rocks a lever 41 which, through a link 45 and lever 52, moves a link 53 carrying a stud 54 so that the latter moves from the inoperative position shown into the stem of a T-shaped slot 34 in a lever 24 to couple it to a lever 23 having an oblong slot for the stud. Thus, when the machine operates, a cam 21 controls the lever 24 so that the lever 23, coupled to the lever 3 by a link 28, engages and disengages the totalizer wheels for subtraction in the correct timing. A similar cam (not shown), is associated with a similar mechanism rendered operative by depression of an add key to engage the totalizer wheels in the same time but for rotation in the opposite direction. Other suitably-shaped cams and connecting mechanisms (not described) may be provided for positive and negative total- and sub-totaltaking. Specification 479,234 is referred to.

Title: Thermometer mounting
IPC: G01K1/14
Filed: 1978-08-14
Abstract: An assembly for mounting a thermometer in an aperture in the wall 10 of a retort comprises an elongated casing 16 receiving the bulb and lower stem of a thermometer in a position to record the temperature within the retort, a sleeve 38 gripping the stem of the thermometer and resting upon the casing to hold the thermometer in place within the casing, the casing being joined to a union piece 20 fitted within said aperture in the retort, and a sealing means 44 which prevents passage of liquid or vapour from the retort to the joint between the casing and union and thus prevents such passage to the interior of the casing. The sealing means is preferably a plastics washer. The assembly differs from the previously used devices in that the sealing means is placed below the joint between the casing and the union and thus is effective in preventing steam or condensed water vapour from reaching the bulb of the thermometer. The invention is useful for thermometers for food canning retorts. <IMAGE>

Patent GB-2019561-A (GB)
Title: Telecommunication systems
IPC: H04B10/69
Filed: 1979-04-12
Abstract: A telecommunication system has a laser-energised multi mode optical fibre 1. Data is input to the fibre by a series of modulators 4 each operating at a different subcarrier frequency. Optical radiation is detected by quadrant photodetector 3 which applies each of its outputs to respective channel sets. Each channel has a band pass filter 8 centred on a subcarrier frequency followed by a non-linear device 9. The signals from all the channels carrying the same subcarrier frequency are combined and the signals passed through band pass filters 11 centred on the second harmonic of the subcarrier frequency. Each of the modulators 4 consists of a plate bonded by a piezoelectric transducer and a pressure plate between which a length of optical fibre is sandwiched. When the transducer is energised the acoustic energy produced applies asymmetric radial strain to the fibre which induces radial or transverse birefringency, hence phase modulation of orthogonally polarised modes. <IMAGE>
Patent GB-2020355-A (GB)
Title: Reed-relay flow measurement device
IPC: G01F3/16
Filed: 1979-04-23
Abstract: A device for measuring the flow of a fluid, which employs a reed- relay 5. The device has a proportioning piston 10 which can slide relative to the relay and longitudinally between two magnetic regions 7, 8. The movement of this piston is determined by the flow of fluid through the device. The piston is magnetic and it is this magnetism which controls the action of the reed-relay causing it to generate an electrical signal which is then counted on an external counter. The magnetic regions do not interfere with the action of the reed-relay, since the magnetic field experienced by the reed-relay is due almost entirely to the magnetism of the piston. <IMAGE>
Patent GB-2021243-A (GB)
Title: Blast furnace tuyere
IPC: C21B7/16
Filed: 1979-05-17
Abstract: A tuyere is disclosed with a partition (26, 28) blocking the direct path between the inlet and outlet orifices 16, 18 in the main cooling chamber 14. Guide members 30, 32 extend from the far side (from the partition) of the orifices 16, 18 towards but not reaching the nose- end wall of the cooling chamber 14. Therefore whichever orifice 16, 18 is used as the inlet for cooling fluid, a fast moving stream is ensured at the nose end of the chamber 14 near the partition. This assists the cooling of the tuyere in this area, which otherwise tends to form a marked hotspot, especially when the inlet and outlet orifices 16, 18 are close together. The nose of the tuyere may be supplied separately with coolant by a conduit passing through the main chamber 14 and the partition may be formed by webs (26, 28) extending between the conduit and the inner and outer wall of the chamber. <IMAGE>
