Title: Improvements in hair waving apparatus
IPC: A45D6/04
Filed: 1937-02-10
Abstract: 482,919. Permanent waving. INDEFRISABLE AUTOMATIQUE. Feb. 10, 1937, No. 4013. Convention date, April 28, 1936. [Class 131] [Also in Group XXIX] In apparatus for permanent waving by super-heated steam the steam is admitted to the treatment chamber by a valve which remains open for a time which can be adjusted and then closes automatically, turning the steam through a byepass to keep the apparatus warm. The treatment chamber 4 is formed as a. cylinder with a gap 5, Fig. 5, through which the tress passes, and an outer covering 7 which can be turned by a handle 12 to grip the tress against a rubber edge 11 of the gap 5 ; the handle 12 at the same time closes an endcover 6 of the cylinder 4. The hair is wound on a roller 3 engaging by a helical thread with the end of a spindle 1 driven by a motor through a flexible shaft 1<1> and clutch 19. The clutch 19 is engaged by a knob 24 and lever 23 through a spring 25 and is so arranged as to slip against the action of the spring when the hair reaches a certain tension. To release the hair the cylinder can be slid lengthwise on a member 8 which also forms part of a valve for regulating the time of admission of the steam. The member 38 can rotate on a member 33, passages 29, 31, Fig. 8, in which admit the steam to and from the chamber 4 through slots 36, 37 and openings 38, 39 in a partition 34 in the member 8 when the valve is in the position shown. On turning the valve these passages open into a slot 35 and the steam is byepassed. To regulate the time of treatment the member 8 carries a pawl 44, Fig. 11, engaging with a ratchet 43 driven at constant speed by a motor. The pawl is held in engagement with the ratchet by a lever 49 carried on the member 8, a roller 51 on the lever 49 runs on a fixed rail 46 having a depression 56 so placed that the roller enters it, thus disengaging the pawl, when the passages 29, 31 are in communication through the slot 35. At starting the part of the member 8 carrying the pawl 44 is brought into contact with an adjustable stop 55, the position of which determines the length of the treatment. The sheath 57 of the apparatus is insulated from the steam pipes 27, 28 by a block 53 of asbestos &c.

Title: Apparatus for recording the duration of sunshine
IPC: G01W1/12
Filed: 1931-02-11
Abstract: 372,777. Sunshine recorders. DUFTON, A. F.. Greenbank, Garston, Hertfordshire. Feb. 11, 1931, No. 4255. [Class 97(iii).] A sunshine recorder comprises two differentially arranged heat responsive elements of which the external surface of one is black and that of the other white. A slight actuation of the controlling element may cause artificial heat to be supplied to the second element and prevent further movement. In the form shown, a blackened bulb 2 containing ether and adapted to be exposed to sunlight is connected through a bent tube 1 containing mercury to an ether bulb 3 surrounded by a heating coil 4 and painted white. A pair of contacts 5, 6 are fused in the tube 1 below the bulb 2 and connected respectively to one side of an .alternating current source 7 through resistance 8 and to the other side through condenser 9, the contact 5 being placed at a short distance above the contact 6. Normally contacts 5, 6 are immersed in the mercury and current flows through resistance 8, contacts 5, 6 and condenser 9. On heat being supplied to bulb 2, the mercury level falls below contact 5 and the current passes through condenser 9, contact 6, mercury column, contact 12 and solenoid 11, the latter operating an armature and starting the clock 10. Immediately thereafter the mercury uncovers the contact 6, the current then passing through the heating coil 4 so that the bulb 3 is brought to a temperature approximately equal to that of the bulb 3, the mercury surface at the contact 6 oscillating slightly to maintain the balance. When the bulb 2 ceases to be heated the mercury surface has to move only the short distance between the contacts 5, 6 to short-circuit the solenoid 11 and stop the clock. The intensity of the incident radiation may be indicated by a meter adapted to measure and record the amount of heat supplied to the coils 4. In a modification operated by direct current the condenser 9 is dispensed with and the contacts 5, 6 are placed below the bulb 3. In a further modification two differentially arranged metallic strips coloured black and white respectively may be used.

Title: Improved Apparatus for the Electric Driving of Ships such as Submarines.
IPC: B63G8/08
Filed: 1917-03-24
Abstract: 127,042. Marks, E. C. R., (Volta Soc. Anon.). March 24, 1917. Systems for continuous-current motors only.- In electric ship-propulsion systems, particularly for submarines, two continuous-current motors are used for each propeller shaft, one highpowered for driving at top speed, and the other low-powered for use at cruising speeds. In one arrangement, starting-up is effected by placing the armatures of the two motors M<1>, M<2>, Fig. 3, in series by means of the switch C, the field coils m<1>, m<2> being connected to the batteries S<1>, S<2> by the switch A. Starting-resistances are controlled by the switches E.. F. The field rheostats R<1>, R<2> are then used to cut out either of the fields, according as to which motor is to work, the switch C being afterwards thrown into contact with either lead 54, 55 so as to cut out the corresponding armature. A reversing-switch D is provided, and a switch B is used to place the two batteries in series or parallel. In another arrangement, a switch which is interlocked with the field rheostats controls the two motors. In its mid-position, the two motors are in series for starting. By moving the switch arm upwards, the rheostats can be adjusted to cut out the excitation of the field of the small motor and to allow full excitation of the large motor; on further movement, the armature of the small motor is shunted, and finally the small motor is discounected. By moving the switch arm downwards, the same sequence is obtained for .working with the small motor. The two motors may be replaced by a single machine having independent different-powered armature windings and independent field windings.

Filed: 1927-11-18
Abstract: 290,728. Bacon, M. L. Nov. 18, 1927. Preserving meat.-Beef, mutton, bacon, hams, tongues. and other kinds of meat are cured by insertion in an autoclave or like vessel which is then evacuated, e.g. to a pressure of about half an mch of mercury. The curing material, which may be in the dry state or in solution, is next introduced at ordinary pressure, or by gravity from an evacuated container, and evacuation is then continued and maintained for the rest of the curing process the time of which is considerably reduced thereby, e.g. to 60-70 hours. As a finishing step pressure may be employed for a short period, e.g. one hour, by introducing air or preservative liquid under pressure. In the apparatus described, the meat is treated in an autoclave A connected to a vacuum pump P through a pipe a<11> and to a tank T containing curing liquor through a pipe s<1> and a valve S. An emptying valve v is also provided. The tank T has a cover t so that it can be hermetically sealed and evacuated from pump P through pipes a<11>, p<1> and valve p<11>. Liquid under pressure may be introduced into the autoclave by a pump W. The autoclave may have heating or cooling pipes for varying the temperature therein.
