Abstract: 1,227,403. Iriter-recorJ gap noise suppression. HONEYWELL Inc. 13 May, 1968 [24 May, 1967], No. 22661/68. Heading G4C. The invention is concerned with the detection and elimination of unwanted signals, referred to as noise, particularly those which are read as information signals from the inter-record gap between normal records for example on magnetic tape, which unwanted signals comprises a number of signals less than a predetermined number. In the preferred embodiment, signals from a magnetic tape unit are fed by way of amplifiers, a deskewing register and an output register to the input bus of a central processor for storage in an area of a main coincidentcurrent memory starting from a predetermined start address. A counter which is preset to said predetermined number (e.g. 8) before each reading operation is decremented by unity for each unit of information (data character) received by the output register. If the end of a record block is detected before the counter has reached zero, the information just read is treated as noise, the reader is not stopped and the next block of data detected is fed to the memory starting at said predetermined start address so as to overwrite the noise signals just stored. Means are provided whereby special short blocks of data (e.g. tape marks comprising unique initial characters) may be detected and the above noise detection mechanism suppressed. This may apply whether the tape is moved forwards or backwards, the initial character in the backwards direction of movement being a longitudinal parity check, transverse parity also being included for each 6-bit character group.

Abstract: 1,229,003. Defrosting. ROBERTSHAW CONTROLS CO. 22 Nov., 1968 [24 Nov., 1967], No. 55603/68. Heading F4H. [Also in Division H1] In a cooling system in which a fan forces air over an evaporator, pressure is sensed downstream and/or upstream of the evaporator and the pressure or the difference between the pressures is applied via a fluid amplifier to a defrost initiation switch to initiate defrosting when icing of the evaporator has blocked the air flow to a given degree. As illustrated, pressure is sensed upstream of the evaporator 14 and is applied to a control nozzle 30 of a proportional fluid amplifier 28 whose other control nozzle 32 is closed. Pressure at an amplifier outlet port 38 is applied to a pressureoperated switch 44 (see Division H1) which, when a given pressure is reached, de-energizes the refrigerant compressor 10 and the fan 16. Defrosting may take place by natural melting, or the switch 44 may be a change-over switch which switches on an evaporator heater when de-energizing the compressor and fan. The control nozzle 32 may be connected to a point downstream of the evaporator so that the pressure difference across the evaporator is applied to the amplifier. The switch 44 is reset to terminate defrosting either manually or by means sensitive to evaporator temperature.

Abstract: 1,233,107. Fluid resistors. GENERAL ELECTRIC CO. Oct. 22, 1968 [Nov. 1, 1967],  No. 50062/68. Heading G3H. A variable fluid resistor comprises a non- rotatable disc 6 provided with slots 7, 8 which are connected to inlet and outlet bores 9, 10 and which are bridged by a slot 13 in a member 5 which is rotatably adjustable to vary the effective lengths of the slots.

Labelling apparatus as disclosed in U.K. Specification 1,129,822 is characterized in that a plurality of label receptacles such as 6a, 6b are provided, and the label carrying elements 4 are divided into different groups 4a, 4b each arranged to co-operate with a different one of the label receptacles in transferring labels from the appropriate receptacle to a labelling cylinder 7. As shown, the elements of each group are arranged in alternating sequence, i.e. a, b, a, b. Respective cams 15 withdraw the receptacle 6a from the path of the elements 4b and the receptacle 6b from the path of the elements 4a. The elements are cam controlled so that their curved adhesion faces extend concentrically to a central pivot 1 as they pass a glue applying roller 5 and the cylinder 7. On passing a receptacle, each element pivots anticlockwise on its axis 3 so that its adhesion face performs a rolling action over the front of a label stack to pick up a label. On passing the cylinder 7 each element pivots clockwise to deliver the label to the cylinder at a faster rotational speed characteristic of the cylinder. An alternative embodiment (Fig. 6, not shown) comprises a labelling cylinder (7), three transfer members (2) rotating about mutually spaced axes and each having two label carrying elements (4), each member (2) being associated with its own glue applying roller (5) and label receptacle (6). In this embodiment the elements may pivot anticlockwise to deliver a label to the cylinder at a slower rotational speed.

Abstract: 1,234,151. Electrolytically depositing layers of nickel-iron alloy. STANDARD TELEPHONES & CABLES Ltd. Jan. 8, 1969, No. 1232/69. Heading C7B. [Also in Divisions H3-5] A multi-layer magnetic bridging structure for the ferrite plate 1 of a "waffle-iron" data store, (see Division H3-H5), is formed by electrolytically depositing a layer 4 of a body-centred cubic nickel-iron alloy having not more than 25% by weight of nickel on a cleaned, lapped and polished molybdenum substrate 3, followed by the electrolytic deposition of a thicker anisotropic layer 5 of a face-centred cubic nickel-iron alloy having between 70% and 95% by weight of nickel. Optionally a further layer 6 of the same composition as layer 4, but thinner, may be added. The layer 4 is formed by using the molybdenum substrate as the cathode in a D.C. plating bath composed of ferrous chloride (FeCl 2  . 4H 2  O), nickel chloride (Ni Cl 2  . 6H 2 O) and aluminium chloride (Al Cl 3  . 6H 2  O) maintained with concentrated hydrochloric acid at apH between 0À7 and 1À0 at 65‹C. Pure iron anodes and a calomel electrode are used, and the cathode is disturbed periodically by knocks always applied in the same direction. The cathode potential as measured between the cathode and the calomel electrode is increased during plating. After washing the plated substrate, the layer 5 is deposited in a second electro-plating bath with an applied magnetic field to give the required anisotropy. The composition of the second bath is nickel sulphate (Ni SO 4  . 7H 2  O), ferrous sulphate (FeSO 4  . 7H 2 O), nickel chloride (Ni Cl 2  . 6H 2 O), boric acid (H 3 BO 3 ), sodium lauryl sulphate and saccharin, the pH being 2À2 and the temperature 20‹ C.

Granulated hop comprises hop powder the particles of which are encrusted with hop extract. The hop powder may be one enriched in lupulin. The term "hop extract" is defined as the dry residue obtained by evaporating to dryness a hop solvent extract viz. an organic solvent extract containing the bitter principles or an aqueous extract of the tannins. The granulated hop has an overall particle size in the range of from 30 to 30, 000 microns and the thickness of the hop extract encrustation amounts to 10 - 10, 000 microns. The granulated hop is produced by mixing the two components by one of the several specified methods, involving mechanical mixing or attrition, blending, spraying or pneumatic agitation. The hop extract may have been moistened with water or organic solvent. Preferably the hop extract is heated to its softening temperature (between 45‹ and 70‹ C) before it is mixed with the hop powder and the mixture, after its initial formation, is suddenly cooled to a temperature of from - 1‹ C to 30‹ C. to aid granulation. Pellets of the granulated hop are obtained by applying a pressure of at least 50 Kg/cm<SP>2</SP>. Mention is made of ordinary mixtures of hop powder with tannin extract.

Latch member 17 is pivoted at 20 to the rod 12 which is slidable in a slot 22 in member 16. The device 18 is pivoted to member 16 and urged in a clockwise direction by a spring 30 which is weaker than spring 30. Member 17 has a surface 33 engageable with an abutment surface on member 18, and has an arm 34 which can abut a face 35 on member 18. Operation. The device is employed in a sewing machine having control mechanism wherein displacement of the pedal changes the motor speed; on release of the pedal the latter moves to an intermediate position where the motor is disengaged and the machine stops with the needle lowered; the pedal is then raised to operate a thread severing device and cause the machine to move into a needle raised position. In the first movement of the pedal the biassing spring 25 maintains the latch member 17 in engagement with shoulder 27. On raising the pedal bar 13 presses 16, with abutment member 18, upwards the faces 36, 33 engaging to turn latch 17 anticlockwise to clear 26 from shoulder 27, the turning also causing arm 34 to engage face 35 to swing 18 against spring 30, allowing faces 33, 36 to clear each other and member 17 to return to the position shown dotted.
