Title: Improvements in apparatus for controlling the delivery of measured quantities of material
Inventor: SMITH ALAN
IPC: G01G13/24
Filed: 1959-02-23
Abstract: 853,605. Automatic feed weighers. LANCASHIRE DYNAMO ELECTRONIC PRODUCTS Ltd. Feb. 23, 1959, No. 6163/59. Class 143 Apparatus for controlling the delivery of material feeds the material to a measuring device, such as a weighing machine, which operates in response to the delivery of a certain quantity of material thereto to cut off the feed, and incorporates a time delay device by which the time lag between the operation of the measuring device and the cut-off of the feed is made to depend on the rate of delivery, the delay device providing a delay which is automatically made a constant fraction of the time taken to deliver the quantity of material necessary to operate the measuring device. The invention is described with reference to an automatic feed weigher in which a conveyer feeds wool to a bucket on a weighbeam, a capacitor being charged at constant current from the initiation of the feed to the time the weighbeam tilts, the delay of cut-off being defined by the time taken to discharge this capacitor at a rate greater than the charging rate. In the circuit shown, microswitch 11 is closed by the weighbeam when the weighbucket empties and energises relay A whose contact a 1  closes to engage the conveyer clutch while contact a 2  initiates charging of capacitor C, the charging current flowing through resistor 19 and rectifier 17 and being maintained substantially constant by virtue of the fact that the pentode V1a, cathode follower V1b and capacitor C constitute a feed-back loop whereby the potential of the grid of V1a, and hence the potential drop across resistor 19, is held substantially constant. When the potential of the cathode of V1b rises above that of the wiper of potentiometer 10, relay B operates to lock the clutch by means of contact b. When the weighbeam tilts, microswitch 11 opens, relay A drops out and its contact a 1  opens while a 2  moves into the position shown, so that capacitor C discharges through resistor 18 and rectifier 16 until the potential of the cathode of V1b falls below that of the wiper of potentiometer 10, when the clutch is disengaged by the opening of contact b. Potentiometer 10 is set so that the time taken to complete the discharge of capacitor C, at the rate determined by the value of resistance 18, after relay B has operated is equal to the "over-run" time of the conveyer (i.e. the time taken for it to come to rest after the clutch is disengaged). As an alternative to the circuit shown, the time delay device may comprise a cam rotated at a constant speed during the loading of the weighbucket until the beam tilts and then driven in the reverse sense at a higher speed to effect stopping of the conveyer when the cam returns to its initial position.

Abstract: 1355938 Making filled wafer biscuits F HAAS 10 Feb 1972 [11 Feb 1971] 6306/72 Heading A2A [Also in Division B8] Filled wafer biscuits are produced in a machine comprising a conveyer belt 2, at least one wafer sheet laying device 4 comprising a magazine 5 and an extractor conveyer 6 for transferring wafer sheets from the magazine to a well 7 over the conveyer 2, and at least one coating device 8 for applying filling material to the wafer sheets on the conveyer belt. The machine shown has three wafer sheet laying devices 4, 4', 4" of which each except the first is followed by a pressing roller 11, 11', and two coating devices 8, 8' each of which comprises a cream reservoir (not shown), an applicator roller 9 and a wiper 10 whereby a curtain of cream 23 is deposited on the wafers. Wafers are accommodated between rows of prongs 20 extending across the conveyer 2. Engagement of a prong with a microswitch 21, 21', 21" initiates operation of the corresponding extractor conveyer 6 whereby a wafer is transferred to the well 7, a support roller (not shown) keeping the wafer substantially horizontal until it is clear of the conveyer 6. Downward movement of the wafer is then assisted by air jets (not shown), and the passage of the wafer down the well interrupts a light beam to stop the extractor conveyer 6. The well 7 has slots, and the rollers 11, 11' are grooved, to allow the passage of the prongs.

IPC: C07C205/59
Filed: 1950-03-14
Abstract: The invention comprises compounds of the general formula <FORM:0673413/IV (b)/1> wherein R is an alkyl group containing from 1 to 4 carbon atoms, R1 is an alkyl group containing from 1 to 4 carbon atoms or a divalent saturated hydrocarbon group forming with the group R2 and the adjacent nitrogen atom a cyclic radical, R2 is a hydrogen atom, an alkyl group containing from 1 to 4 carbon atoms or a divalent saturated hydrocarbon group forming with the group R1 and the adjacent nitrogen atom a cyclic radical, and their salts, and a process for the preparation of the above compounds by reacting the propylene oxide <FORM:0673413/IV (b)/2> and the amine <FORM:0673413/IV (b)/3> wherein R, R1 and R2 have the above signif cance, or by reacting epichlorhydrin with the compound <FORM:0673413/IV (b)/4> in the presence of alkali to form the above propylene oxide which is then reacted with the amine.  The preferred compounds are those having the two substituents in the para position, and such compounds may be further substituted in the meta position with respect to the ester group, by an alkoxy or aliphatic acylamino group containing not more than 6 carbon atoms.  Salts are formed by the usual methods of converting bases into salts, e.g. hydrochloric, hydrobromic and sulphuric acids and organic acids such as lactic acid may be used for salt formation.  the groups R, R1 and R2 may, for example, each be a methyl, ethyl, propyl or butyl group including the isomeric forms of the latter two groups, or R1 and R2 may complete a piperidine ring.  In the examples the following compounds are prepared: methyl p - (g  - diethylamino - b -hydroxy)-propoxybenzoate and the corresponding ethyl and n-butyl esters, ethyl m-(g -diethylamino - b  - hydroxy) - propoxybenzoate, n - butyl p - (g  - dimethylamino - b  - hydroxy)-propoxybenzoate, ethyl p - (g  - di - n - butyl-amino - b  - hydroxy) - propoxybenzoate and the corresponding g -piperidino and g -isopropylamino compounds, isobutyl o - (g  - diethylamino - b  - hydroxy) - propoxybenzoate, ethyl p - (g  - diethylamino - b  - hydroxy) - propoxy-m-methoxy-benzoate and the corresponding m-ethoxy and m-acetylamino compounds.  Propylene oxides of the general formula <FORM:0673413/IV (b)/5> where R has the above significance, are prepared by the method referred to above.  In an example, ethyl p-(b -g -epoxy)-propoxybenzoate is prepared from epichlorhydrin and methyl p-hydroxybenzoate.  The corresponding compounds containing in the meta position a methoxy group, an ethoxy and an acetylamino group are prepared by a similar method.  Ethyl m - acetylamino - p - hydroxybenzoate is prepared by the nitration of ethyl-p-hydroxybenzoate, catalytic reduction of the nitro group and acetylation of the resulting amino group with acetic anhydride.

Title: Improvements in the manufacture and production of lubricants
IPC: C10M109/00
Filed: 1934-03-17
Abstract: Synthetic processes for the manufacture of lubricants are carried out in presence of such added organic oxygen compounds as are antioxidants and contain a cyclic radicle and at least one oxygen atom directly connected with 2 different carbon atoms. Aromatic ethers, diphenylene oxide, alkyl derivatives thereof, and naphthyl-ethyl-ether, in proportion of 0,05--15 per cent are suitable.  The synthetic may be prepared by "voltolization"; polymerization or condensation, e.g. of olefines, mineral or tar oils, waxes, fats, high molecular acids or alcohols, in presence of aluminium chloride, zinc chloride, iron chloride, or like catalyst; or by hydrogenation of rubber, resins, or other polymers of high m.w. The synthetics may be added to lubricating oils and greases, 0,1--10 per cent being suitable to reduce the setting point and improve the viscosity index and stability.  For example, 100 lb. of chlorinated paraffin wax is diluted with 100 lb. of kerosene and condensed at 30--40 DEG  C. for 24 hrs. with 5 lb. of naphthalene in presence of 5 lb. of diphenyl oxide or diphenyl ether, 7 lb. of aluminium chloride, and 6 lb. of zinc oxide.  The inorganic matter is then removed by centrifuging, the diluent by distillation, and the unchanged wax and light lubricating oil by steam distillation in vacuo.  3 lb. of the highly viscous oil product added to 100 lb. of a mineral machine oil reduces the pour point 25 DEG  C.
